or less irregularly punctured, smooth in part, tumid, sides and po^iterior 

 face of propodeum finely shagreened, its basolateral area (undefined) 

 finely punctate. 



Abdomen 9 ovate, ist tergite with the surface punctate except the 

 translucent depressed margin but not closely nor coarsely, remaining 

 tergites with the surface obscured by oblique fine piliferous punctures 

 and the declined hairs from them, sternites with the piliferous punctures 

 stronger. Abdomen $ more elongate, tergites i and 2 more strongly 

 punctate, the translucent margins of the tergites narrower, tergite 7 

 with a flat narrow brown longitudinal smooth area extending its entire 

 length. Sternites 2-4 more or less emarginately depressed posteriorly, 

 the 4th with a triangular flattened reversed tooth on either side, 5th de- 

 pressed shining, arcuately emarginate behind, sixth retracted, the basal 

 portion with a broad median longitudinal channel and fulvous hairs 

 on either side, with an oval apical process bearing a blunt spine on its 

 ventral side just before the apex. 



The $ has the legs more incrassate, the anterior claws large and 

 evenly cleft, the anterior tibiae produced into a curved flattened apical 

 spine in the axis of the tibia, the middle tibiae are greatly subtri- 

 angularly incrassate in the middle with a much greater flattened spinous 

 process at the end which bears a brush of peculiar hairs a little before 

 the apex, its basitarsus expanded apically, the 3 median tarsal joints 

 cordate (in all the tarsi), the hind tibiae widest a little beyond the mid- 

 dle within and bear on the inner surface beyond, (as also the basitarsi), 

 long shining white hairs. 



$ Mandibles elongate, acute, the tooth reduced, bearing a tuft of 

 white hairs at base. Antennae beyond the basal bulb with depressed 

 areas, truncate at the end. 



$ Seventh sternite developed into two elongate apical parallel 

 membraneous lobes separated by a narrow slit, with sparse whitish hairs 

 apically, bent at the base of the slit and narrowed apically to y blunt 

 point, with two basal struts much as in Hylaeus; 8th sternite with a sub- 

 quadrate basal piece and an apical elongate median process strongly 

 chitinized, irregularly prismatic with four sides, with a gentle dorso- 

 ventral sigmoid curve, produced about as far as the width of the basal 

 piece, with two broad basal struts not so long as the apical process, 

 parallel separated from each other by a slit nearly as broad as each 

 strut. 



Edeagus with the cardo transverse twice as broad as long a little 

 produced medially, the stipes with the inner angle sub-basal, the outer 

 side sinuously emarginate near the base of the sagittae, with a slender 

 curved apical process arising near the apex of the sagittae ; sagittae 

 strongly geniculate near the base, their inner margin notched at base 

 and then somewhat expanded, their main mass lying above the plane of 

 the stipes and cardo, but their tips deflexed below the end of the stipes.
