 PISOXOPSIS Fox. 



(1) Pisonopsis triangularis, n. sp. 



9. -Length G mill. Stature of Bothy nostethns d/stinctus Fox^ 

 Bhck, closely, op iquely punctate. Ocelli arranged almost in an 

 equilateral triangle. Eyes slightly convergentabove. with a median 

 emargination within, but not deeply emargiuated, as in Pison. 

 Clypeus wMth a median triangular production Mandibles beneath 

 strongly emarginate at basal third and rufousfrom the emargination 

 to apex. Metathorax rugulose, with a median furrow and a delicate 

 carina, the furrow lineated on either side trom the carina. Wings 

 sabhyaline. the tegulae, stigma and veins brown-black; the sub- 

 median cell is distinctly shorter than the median ; the first recurrent 

 nervure is interstitial with the first transverse cubitus, while the 

 second recurrent joins the second submarginal cell at its apical 

 fourth. Abdomen distinctly punctate, the dorsal segments 1-4 

 broadly depressed at apex and clothed with a silvery or at least glit- 

 tery pubescence, e.speci illy noticeable laterally; ventral segments 

 2-5 niiTowly testaceous at apex and finely, closely punctate. 

 Longer spur of hind tibiae neirly as long as the basal joint of tarsi.

Type, No. 50G4, U- S. N. M. 



NITELIOPSIS Saunders. 



(2) Niteliopsis striatipes, n. sp. 



9.— Length 6.5 mm. Head and thorax black, finely, closely, 

 cribrately punctate, the face, temples, pronotum and pleura with 

 a .silvery pubescence; abdomen rufous; legs black, the tarsi more or 

 less rufous, brownish at base, while all the tibiae have a white stripe 

 outwardly. The clypeus is strongly produced medially and again 

 produced medially into a quadrate production. Wings hyaline, 

 broadly fuscous at apical margins; the second submirginal cell re- 

 ceives both recurrent nervu res; while the submedian and median 

 cells are nearly of an equal length.

 peus, the scape beneath, a stripe on the front tibiae anteriorly and a 

 slight line on middle tibiae near the base, yellow; mandibles, except 

 apex,black. The metathorax has a distinct triangular area at base, 

 which is smooth except some liueations at extreme base. Wings
