other species here transferred to the genus Stilbula. It is easily dis- 

 tinguished from the other species known to me, except -fioridana 

 (Ashmead), by its different coloration and also by having the pro- 

 podeum deeply and broadly hollowed out medially, this median de- 

 pression as well as the broad spiracular furrows with coarse transverse 

 striae, the surfaces between the median depression and the spiracular 

 grooves very prominent and very coarsely rugose. The propodeum 

 laterad of the spiracle is not strongly elevated as in some of the 

 species. 



The species is very similar to ftoridana (Ashmead), apparently 

 differing only by having the thorax more distinctly and more 

 extensively marked with black. 



STILBULA MANIPURENSIS (Clausen), new combination 



Schizaspidia manipurensis Clausen, Proc. Ent. Soc. Washington, vol. 30, pp. 



80-86, 1928. 



In this species the antennae of both sexes are long and cylindrical, 

 the scutellar process is comparatively short, and the costal cell is 

 not especially broad. These characters place the species in Stilbula 

 instead of Schisaspidia^ although the propodeum is without the pro- 

 nounced elevations laterad of the spiracles usually characteristic of 

 Stilbula. 



The characters pointed out by Clausen for distinguishing this 

 species from tenuicomis (Ashmead) will also distinguish it from 

 cyniformis (Rossi). The absence of a conspicuous fuscous cloud be- 

 low the stigmal vein will also help to distinguish the species. 



The statements "face with fine longitudinal striations, the front 

 smooth" in the original description appear to me to be inaccurate. 

 Actually that part of the head below the antennae is nearly smooth, 

 without any striations but with obscure suberased punctures except 

 on the clypeus, which is perfectly smooth, while the frons between 

 the scrobe and eye margins is longitudinally rugose. The head 

 viewed from in front is only about twice as broad as long. The 

 ocelli are very nearly in a straight line. 



Genus ORASEMA Cameron 



This genus was originally described from Panama with Orasema 

 stramineipes Cameron as the genotype. The genus apparently is 

 confined to North and South America, the West Indies, and the 

 Australian region. 



Specific characters consist for the most part of slight differences 

 in sculpture, which are hard to definej Color of the legs and an- 

 tennal scape and to some extent the degree of metallic coloration 

 of the body seem to be significant but must be used with caution.
