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 BoUtotherus cornutvs^ Panz., it differs from all other 

 Bolitophaginoe in tlie last joint of its maxillary palpi being 

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

 lymmus and some others, are not Avell 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.
