Length to tip of anal prolongation i6 — 17 mm. ; to tip of closed wings 22—23 

 mm.; width of base of pronotum S'/\—6 mm. 



Only males of this neat little species have been brought to my notice. 

 The cell opened by the separation of the postcostal ulnar nervure from 

 the postcostal one is longer in this than in the other species. Three spe- 

 cimens examined Irom Southern California. 



Mr. Morrison secured for me, in Nevada, se\-eral very small speci- 

 mens belonging to this genus Platypedia, which measure only 17 — 18 

 mm. to the tip of the closed wing-covers ; but they appear to be only 

 dwarfed specimens of /*. //////r7?;«'. Thev are not nearly as hair\- as the 

 new species here described, and chiefly display in miniature the charac- 

 teristics o{ P. piitnami, as we find it in the same section of our country 



By counting the postcostal areole as the first ulnar, we have six 

 areoles across the wing-cover, instead of the usual five. The commonly 

 cited second ulnar (third of our method) is longer and more nearly tri- 

 angular in the new than in the other species previously described.

 Hitherto found only near Vera Cruz, Mexico ; unless narrow speci- 

 mens o( JAVf^w/.sv^/A?/),;?/-?'///;?, Say, which lack one of the apical areoles 

 of the wings, should prove to be the same as the Mexican form given as 

 the type. Several specimens of J/ parvida have been examined by my- 

 self, in which six apical arciiles were present in the one wing and five in 

 the opposite one. 



PRUNASIS, Stael. 

 P. venosa, new sp. 



Tale green, or faded stiaw yellow, feebly pubescent ; form nearly the same as 

 that ol yl/i/'rtw/j,-/?/,^/,?;-!'///;?, but witli the abdomen less contracted at tip. Vertex 

 with a belt ot large dusky spots extending from eye to eye, but sometimes obsolete, 

 so as to leave only one large spot on the centre and enclosing the ocelli ; supra-anten- 

 nal plates more or less dusky ; front banded with fuscous between the transverse 

 ridges, the middle line infuscated wider above and interrupted there by a dagger- 

 shaped yellow mark ; antennas yellow, piceous at tip of second joint and base of 

 third ; rostrum reaching to near the tip of posterior coxpe, with the apex more or less 

 infuscated. Pronotum transverse, smooth on the middle line with the oblique im- 

 pressed lines each side well defined, and the surface curvedly wrinkled between them; 

 the lateral margins feebly sinuated, very narrow, but abruptly expanded, reflexed 

 and impressed at the humeri ; meso-notum moderately convex, a little sinuated each 

 side, with four ob-deltoid obscure fuscous spots, of which the two inner are very
