Easily recognized among its immediate congeners by its 

 black head, pronotum, and pygidium, also from Matiricei and 

 egreg'ia by the very much shorter laminae of its antennae, and 

 from sinuaticollis by, inter alia, the much less strongly sinu- 

 ate base of its prothorax, and the considerably closer punctu- 

 ration of its elytra. I have founded the description on one 

 of two female examples in the South Australian Museum 

 rather than on the unique specimen (male), in my own col- 

 lection, because the latter is a broken specimen, with only 

 the basal lamella remaining of its antenna! flabella, and there- 

 fore I cannot describe its antennae satisfactorily. There is a 

 difference between the two females in the Museum in respect 

 of the pygidium, fhe surface in one of them being somewhat 

 dull and coriaceous, but I regard this as a mere accidental 

 variation.
