 Jacmel. December, 1912, W. M. Mann.^ 



This species differs conspicuously in appearance from the preceding 

 ones in lacking any distinct light markings, the color of the head and 

 tergites being fuscous or blackish throughout, though under the micro- 

 scope some individuals show very obscure traces of lighter markings 

 arranged much as in the other species. Legs and under surface of 

 the body yellowish. Antennae blackish, uniform. The impressed 

 area above the base of each antenna is circular and sometimes yellow 

 in color. The striations of the tergites are in general similar to those 

 in the preceding species. The inferior processes of the posterior 

 tergites are distinct; but they are throughout shorter and more 

 obtuse than in the other species, the greater shortness and obtuseness. 

 being strikingly obvious in the case of the penult tergite. 



Length, 4-6.5 ram.
