AMERICAN NEUROPTERA. 365 



IVIYR.^IELEONOIDEA. 



MYRMELEONID^E. 

 Acaiithaclisis fallax Eambur. 



A male from Cuernavaca, June. Widely distributed throughout 

 the tropical regions of America. 



Iflyruieleon iininaculatus De Geer. 



Specimens from Cuernavaca, June, and Teocelo, Vera Cruz, 

 August, do not differ much from our forms. 



Bracliyiieniiiriis Tersutus Walker. 

 B. mexicana Bauks. 



I think my species must be the same as Walker's, but several of 

 his statements are considerably at variance with all my specimens. 

 Several specimens from Cuernavaca, Durango and Esclava in Sep- 

 tember and October. 



WlC'KOLiEON gen. uov. 



No spurs; legs short; first tarsal joint of leg'l as long as next 

 three. Three cross-veins before the origin of radial sector; anal 

 vein ends near middle of hind margin, about over the origin of the 

 first fork of the radial sector ; radial sector with but three or four 

 branches; between anal and cubital veins but one series of cells (in 

 this respect resembling Crypfoleon and its allies) ; sometimes a few 

 of the costal veinlets forked ; in hind wings the cubitus does not 

 fork till end of the anal. Antennae short, capitate. 



Type 31. apicalis. 



Readily separated from all other genera on account of the sim- 

 plicity of its venation. From Maraccmda it is distinguished by the 

 fact that the cubital fork of hindwings does not run parallel to the 

 anal. It is probably closely related to Hagen's Myrmeleon pygnueus. 



Mi<^roIeoii apicalii^ n. sp. — Face browu ; two median pale spots and one 

 each side from the lower part of eye ; vertex black ; a white mark each side above 

 the eye, and sometimes four pale dots near the middle; antennae annulate, club 

 yellowish ; pronotum brown, a median pale stripe on anterior part, and some- 

 times a pale spot on each side ; thorax .brown, a few pale spots, mostly on the 

 lateral lobes; abdomen brown, the basal segment rather reddish ; legs and palpi 

 pale yellow, with many black bands. Wings hyaline, the apical third brown ; 

 the pterostigma large, snow-white; venation dark brown and margined with 

 brown, some of the longitudinal veins interrupted with white; around the tip, 

 between each pair of veinlets, is a minute white dot. Hind wings marked like 

 the front pair. Length 15 mm., expanse 29 mm.
