black. Wings hyaline, iridescent, the nervures and stigma black. The 

 oral region, u andibles, and a spot on the pleurae below the tegiilae ru- 

 fous. Antennae, thorax, and legs covered with a pale pile. Median seg- 

 ment coarsely aciculated, the basal area more shining, almost smooth. 

 Pleurae strong^ aciculated, almost punctured, the upper part of the 

 mesonotum smooth and shining, the lower part almost striated. Abdomi- 

 nal petiole curved, as long as the second segment and the half of the 

 third. Apex of metanotum with an oblique slope. Female. Length 2 mm.; 

 terebra one-half mm. Taken near Stanford University, California. 



Ophionidae. 



Enytus gen. nov. 



Clypeus not separated. Eyes not emarginate, converging at the top. Me- 

 tanotum with two transverse keels, on the middle only with the basal 

 one, the second more distinct. Fore wings without an areolet. Claws sim- 

 ple. Apex of clypeus broadly rounded. Abdomen of equal thickness from 

 the first segment, not compressed; the post-petiole clearly separated. 

 Apical nervures in hind wings entirely obliterated. Abdomen aciculated. 



This genus can only be confounded with the Indian genus Bosmina 

 and with Amorphota known from the Palaearctic and Neartic Regions; 

 the latter has an areolet; the former has the claws armed with stout 

 stiff bristles and the metonotum is areolated; in both the hind wings are 

 provided with nervures at the apex. 



3967 Enytus maculipes sp. nov. 



Black, a mark on the under side of the scape, mandibles except at the 

 apex, palpi, four anterior coxae, trochanters and the apical joint of th3 

 hind trochanters pale yellow; the rest of the legs rufo-fulvous, the hind 

 coxae, base of trochanters, femora, base and apex of tibiae and the hind 

 tarsi, black; the base of hind tarsi broadly and the calcaria testaceous. 

 Wings hyaline, the stigma and nervures fuscous. Female. Length 4 mm., 

 ovipositor 1 mm. Taken near Stanford University, California. 



Head opaque, coarsely alutaceous, covered with white pubescence. Tho- 

 rax closely minutely punctured, the median segment more closely than the 

 rest, its apical slope finely closely transversely striated. First abdominal 

 segment smooth and shining, the rest opaque, aciculated, covered with 

 white pubescence. Radial cellule wide; the transverse cubital nervure 

 short, the recurrent is received double its length from it; the transverse 

 median joins shortly beyond the transverse basal. Basal two joints of the 

 flagellum equal in length.
