4 XVII A NEW MYRMELEONID FROM YUCATAN NATHAN BANKS Specimens of an ant-lion fly and the larvae collected in caves in Yucatan occurred near the entrance of the caves. These specimens prove to belong to the genus Eremoleon, one species of which was known from Cuba, and one from Mexico and Arizona. The Yucatan species is different from them, and as the case with many cave forms~ it differs in the longer appendages, legs, antennae, wings. Eremoleon longior n. sp. Body pale yellowish; head with a large black mark around antennae, truncate in front, above reaching to vertex; across vertex are three dark spots in a row, the laterals are transverse, the middle one consists of two elongate spots, close together and not divergent behind (in macer these diverge behind). Last joint of maxillary palpi partly dark, tip of antennae very dark; pronotum with a more or less distinct large dark mark, divided by a pale median stripe, each side behind are two shorter, curved pale stripes, uniting in front (much as in 1nacer); rest of notum largely dark, but with a median pale line on front part, and sorne pale each side near base of wings. Abdomen with segments dark on apical half above (as in macer). Legs pale, dark at tips of femora and tibiae and faintly toward base of tibiae. Fore wings hyaline, venation pale, marked with dark streaks (as in macer); many cross-veins wholly or partly dark; stigma white, with dark at base, and a larger dark cloud at rhegma, that near end of cubital fork scarcely distinct. Head as in E. macer; antennae much longer than in macer, reaching beyond base of the abdomen, latter a little longer th an in macer, pronotum also more slender than in macer. Legs and their parts also much longer th an in macer, the long inner spur of the front tibia being nearly as long as the distance from eye to eye. Wings a little longer than in macer, but with no more veins, the cells thus often longer than in that species; six to seven cross-veins before radial sector (eight or nine in macer), radial sector with eight branches, a few costals toward stigma are forked, the apical area is without gradate veinlets (normally several in macer). Length of fore wing 32 mm., width 9 mm. From Yucatan; Xtoloc Cenote Cave, Chichen Itza June 24; Chakxix Cave, Tekax, August 1; Puz Cave, Oxkutzcab, July 20; ail taken by A. S. Pearse. Type M. C. Z. No Other specimens, which were doubtless E.longior, were seen in San Bulha Cave, Merida, J uly 13; Ebizt Cave and second cave on the San Roque Road, Oxkutzcab, July 18 and 23. Readily separated from E. macer Hag. by more elongate body, legs, and antennae; by few cross-veins before radial sector, and lack of apical gradate veins. According to the descriptions, Segura vitreus Navas from Cuernavaca, and N ovulga mexicana Navas from Vera Cruz are the same as Eremoleon macer; both are said to have eight or nine cross-veins before radial sector, and the figures show a denser venation th an E. longior. 1 have specimens of E. macer from Cuernavaca. 235
