The original description by Xewman is as foUows: 



Niger, rugosus, abdominis segmentis 3 ultimis rufus; antennarum articulis 4 et 5 

 extus, femora apice extus, tibiae basi extiis nivea; proalse ante apicem fascia transversi 

 lata fusca stignatae. (Corp. long. 5 unc; alar, dilat. 775 unc.) 



Somewhat resembles 0. coronatus, a species inhabiting the south of Europe, but 

 differs in the detail of its coloring; the head has a crown of tubercules, is rugosely 

 punctvired, and entirely black; the antennae (a character of the genus) are situated 

 immediately adjoining the mouth at the insertion of the mandibles, and appear as if 

 belonging to the instrumenta cibaria; they are black, with the exception of the exterior
