The above abridged description of Walker fits very well (as 

 far as it goes) for the insects I refer to this species, but another 

 supplementary description drawn up from the specimens ex- 

 amined may serve to define it better. The meso- and meta-notum

 brown, antennae ferruginous, hirsute, as long as the body. 

 Abdomen dark-brown in the disk ; last dorsal segment, supra-
