subtruncate behind, about as long as the dorsal um; radial cell nar- 

 rowly elongate, truncate, and with an appendiculation; three sub- 

 marginal or cubital cells, the first much larger than the other two 

 united, the second triangular, petiolated and receives both recurrent 

 nervures, the third submarginai oblique and is a little narrower above 

 than below; cubital vein of hind wings originates far beyond the 

 apex of the submedian cell ; tibia? and tarsi scarcely armed with 

 spines, middle tibia? one-spurred ; anterior tarsi without comb; pul- 

 villi large, claws small, entire ; abdomen narrower and a little 

 shorter than the thorax, dorsal segments 1-3 transversely depressed 

 at base and apex ; second dorsal without any longitudinal impression 

 in the middle; last segment conical, without pygidial area. 



Niteliopsis plenoculoides Fox. 



IV. plenoculoides Fox, Psyche, Nov. 1893, p. 555. 9 . 



9- — Clypeus strongly carinated down the middle; front finely 

 granulated, distinctly impressed down the middle, along the inner 

 eye-margins the front is finely punctured ; eyes strongly convergiug 

 to the top, the space between them at the vertex is about equal to 

 one-half of the space at the clypeus ; ocelli in a triangle, the lower 

 one situated a little further away from the hind pair, than the hind 

 pair are from each other ; from each hind ocellus, there extends down 

 a short furrow, which reaches a little beyond the fore ocellus ; an- 

 tenna? tolerably long, reaching to about the tegular, the flagellum 

 tapering on apical half, joints 2 and 3 of the flagellum longest, the 

 first and fourth about equal ; dorsulum with exceedingly close and 

 fine punctures ; metathorax above and on the sides finely granulated, 

 with indistinct striations when viewed in certain positions, at the ex- 

 treme base of upper surface there is a transverse series of small foveae 

 and down the middle there is an impressed line (this is not distinct 

 in one specimen), the posterior face transversely rugose ; tibia? and 

 tarsi, with exception of the calcaria unarmed; tarsal claws rather 

 short, stout and not toothed ; abdomen elongate-ovate, the first three 

 dorsal segments when viewed from the side are seen to be contracted 

 basally and apically; last dorsal segment without a pygidium ; three 

 submarginai cells, the second petiolated, receiving both recurrent 

 nervures, black; two transverse spots on the collar above, posterior 

 half of tubercles, a spot near the middle of hind tibia? and the tibial 

 spurs, whitish; apex of mandibles tegulse and tarsi, testaceous; wings
