1 SOME MEXICAN NEUROPTERA. BY NATHAiY BANKS. The following sixteen species of Neuroptera were collected by Dr. Gustav Eisen and Mr. Frank H. Vaslit mostly in the Cape Region of Baja California; a few, however, are from Tepic, Territory of Tepic. Although the collection is too small for generalization, it may be noted that the described species from Baja California were previously known from California ; and there is not a single species of general distribution in the United states. The three species of Chrysopa which appear to be new have the wings less veined than usual, the cells being larger than in our eastern species. Of the three species from Tepic one appears to be new, though it would seem strange that such a prominent insect had escaped observation. All of the specimens are alcoholic. SIALIDB. R~~PHIDIA AUSTRALIS nov. Sp. Length 13 mm. Face yellowish; palpi fuscous, annulate with white ; antennz yellowish, darker toward tips ; head granulate, above and behind shining greenish, with a smooth, elongate, rufous spot reaching nearly to the ocelli; sides of head behind the eyes straight. not convex; prothorax slender, rufous, contracted before middle, granulate, each granule giving rise to a short hair, an indistinct black fork on the basal portion ; legs pale yellow ; abdomen black, with many longitudinal rows of yellow spots, those on sides are larger and more or less connected, a black median line on the yellow venter, ovipositor nearly as long as the abdomen, upcurved. Wings quite short, but six or sel-en costal transverse veinlets, subcosta runs into the costa at a point before the pterostigma twice the length of the latter; pterostigma short, 2n SER., TOL. 7.

Previousl~ known from Arizona, Texas, California and Mexico. BRACHYNEAIURUS CALIFORNICUS nov. SP. Length? 26 mm., 8 35 mm., alar expanse mm. Head yellowish, a broad fuscous band through antenna1 sockets from eye to eye, vertex with two transverse rolts of fuscous spots, and behind on each side a brown and a black spot; antenne with two basal joints pale, a band in front and behind on first one, rest annulate with fuscous; prothorax with a broad fuscous stripe each side, which is forked in front and contains a pale spot behind; on each lower side is a shorter and less definite fuscous stripe; many fuscous spots on each upper side of mesoand metathorax, forming a more or less maculose stripe; other spots on middle, some of them shining black; a broad black stripe below wings, containing an interrupted pale line; legs thickly dotted with fuscous, black on tips of tibiz, third and fourth tarsal joints wholly, and the tip of the fifth joint; spurs about as long as the basal joint. Abdomen of $ longer than the wings, of the? shorter; pale, lineated with fuscous, near the tip often broken into spots more or less connected; second segment mostly fuscous, the others with a median and side stripes, the former narrow in the middle, usually wanting on basal part of basal joints, last segment almost ~vholly fuscous. Nearly every~vhere scantily clothed with white hair and black bristles. The appendages of the $ pale, and dotted with fuscous, twice as long as last segment, slender, bowed and slightly upcurved, a comb of stiff bristles above near tip. Wings narrow, hyaline; veins fuscous, pointed with white; small fuscous spots, most distinct on radius and

Numerous specimens from San Lazaro, Sierra El Taste and San Jos6 del Cabo, Baja California. September. By its biareolated costal space it is evidently related to B. i~zscri$tzss Hagen, but the markings are quite different. BRACHYNEMUKUS FRATERNUS nov. sp. Length? 18 mm., 8 26 mm., alar expanse mm. This is so extremely similar in structure and in coloration to the preceding species (B. calzfornicus) that it may be but a small variety of it. But the specimens were taken at the same time and place, and show no intermediate sizes, so I shall consider it, for the present at least, as distinct. It differs from B. calfornicus, besides the size, only in that the appendages of the 6 are scarcely twice the length of the last segment of the abdomen; and the markings on the sides of the abdomen of the 6, and on the prothorax are usually much less distinct. Several specimens from San Lazaro and San JosP: del Cabo, Baja California. September. Length? 28 mm., 6 42 mm., alar expanse min. Head yellowish, a broad black band across antenna1 region, vertex with two comma - shaped black spots, sometimes connected behind to the prothoracic stripes; antennz brown, the basal joint pale above, annulated with pale; prothorax yellowish, with a dark brown stripe each side, forked at posterior third, inner branch reaching an-

Wings hyaline, veins pale; both pairs evenly spread with many small fuscous spots, of about equal size, usually having for their center the base of a transverse veinlet; pterostigma large, distinct, cream yellow. Wings broad, costal space not biareolate till near middle of wings, space behind radius simple, cubitus forks beyond the origin of radial sector, but before the forking of radial sector. Antennz of 8 longer than thorax, a little shorter in the? ; spurs longer than basal tarsal joint; abdomen in the $ longer than wings, in the Q shorter; appendages of the $ shorter than last segment of abdomen, nearly parallel, upcurved, their tips divaricate, a comb of stifi bristles near the tip above. 4 number of specimens from Tepic.

Venation like U. hynlina. Several specimens from San Jos6 del Cabo, September, and Sierra El Taste, Baja California. Differs from U. hynlimz principally in the shorter antennz and light colored pterostigma.
