 modice elongato, secundo longiore quam latiore, cseteris gradatim 

 brevioribus et compressis, 7-10. subcordatis, ultimo obcordato, 

 ProtJiorax gibbosus, in medio bicornutus, lateribus crenatis, pos- 

 tice rotundatis. Elytra elevata, parallela, prothorace basi latiora.

 breves. Prosternum postice verticale. Abdomen breviusculum. 



Of this remarkable insect I have seen only a single speci- 

 men, and this, without doubt, a male. While in habit it is 

 most like Bolitotherus cornutus, Panz., it differs from all other 

 Bolitophaginge in the last joint of its maxillary palpi being- 

 long and fusiform. The epipleurse of the elytra, as in Ca- 

 lymmus and some others, are not well marked off from the 

 flanks of the elytra. As in most other genera of this sub- 

 family, it is probably, in a perfect state, covered with a hard 

 brownish crust, remains of which are still visible.
