cept disk slightly beyond ocelli and occiput, which are more or less 

 black, sometimes lower hind edge of genae more or less black, and on 

 several specimens the black spot of vertex merging caiidad with occip- 

 ital black area, also proceeding over the front below antennal fossae, 

 the frontal black not solid, side margins of antennal scrobe and 

 ocular space narrowly yellow; scrobe yellow, scape lemon yellow, 

 sometimes with a cloudy black stripe on exterior lateral face, pedicel 

 brown at base and sometimes above, otherwise yellow, flagellum 

 reddish brown to light fuscous above, or quite uniformly yellowish 

 brown ; pronotum mostly ochreous-yellow, barely lighter than yellow 

 of head, a discal dark brown spot, reaching anterior and posterior 

 margins on one specimen, and almost lacking on another, mesothorax 

 ochreous-yellow or rufous-yellow, disks of prescutum and scutellum 

 always brown-black, their margins usually narrowly yellow, or dark 

 to margins on one specimen, hind margin of scutellum always so, tops 

 of scapulae and axillae with varying degrees of brown, but immacu- 

 late on the type, parapsidal and scutello-axillar grooves never dark- 

 ened completely; metathorax, except pleura, and lateral and posterior 

 surfaces of propodeum somewhat variously, ochreous-yellow; legs 

 mostly lemon yellow, posterior coxae with an exterior longitudinal 

 black stripe, femora each with a superior black stripe, never includ- 

 ing entire aspect, and not much larger or intense on hind than on 

 front femora, fore tibiae immaculate or faintly dusky, middle and 

 hind tibiae dark brown outwardly, somewhat more extensively and 

 densely on hind legs; submarginal band light brown, almost amber, 

 faint in all the specimens at hand, slightly broader than length of 

 stigma, about a half longer than wide, distal margin broadly rounded, 

 this edge scarcely extending beyond apex of stigmal vein and feebly 

 dilated at the middle, not parallel with proximal margin, the sides 

 converging to blunt terminus, secondary band almost imperceptible ; 

 petiole ochreous-yellow, dorso-median line broadly, sides and venter 

 sometimes dark brown, abdomen mostly yellowish brown, a poorly 

 demarcated dark-brown angular band above but first segment almost 

 entirely immaculate, and one specimen with entire posterior half 

 of abdomen brown black. 



Head on average slightly less than four-sevenths as long as wide, 

 face from above not broadly and uniformly rounded, but almost 

 forming a straight transverse line as seen from above, occiput less 

 than moderately concave ; several small umbilicate punctures behind 

 anterior ocellus, these more numerous on occiput; genae bare, smooth, 

 shiny; malar space coarsely strigose below groove, finely strigose 

 above mesad of groove, front with shallow, inconspicuous, and rather 

 large hair-bearing reticulations, hairs whitish, sparse; antennae mod- 

 erately stout, pedicel a fourth longer than Fl, F2 to F5 equal in
