ghbuli/orme, Macl. ?), and the conspicuous puncturation (large and 

 fine punctures intermingled) which extends all across (but in a 

 somewhat acervate manner) the retuse front face of the pronotum. 

 The part of the frontal margin in front of the frontal wings is 

 (as in B. globuliforme, Macl., nitens, Blackb., cfec.) very short.

B. CARINATUM, Sp.nOV.- 



Breve; subrotundatum; sat nitidum; supra glabrum; subtus 

 hirsutum; rufo-brunneum ; mandibulo sinistro (superne viso) 

 extus vix sinuato; capite fere ut B. mandibular is, Blackb., sed 

 eminentia frontali marginum frontalium extremitates posticas 

 conjungenti, capitis margine utrinque magis elevato; prothorace 

 fortiter transverso, supra aequali (foveis sublateralibus exceptis), 

 minus acervatim minus sparsim (a partibus lateralibus et anticis 

 retrorsum et medium versus gradatim magis sparsim) sat fortiter 

 punctulato; scutello vix vel subobsolete punctulato; elytris sat 

 fortiter 15-punctulato-striatis, striis 14*^ 15^que baud (vel antice 

 vix) inter se confluentibus (9^ antice abbreviata), interstitiis planis 

 vel vix subconvexis, femoribus posticis subtus sat crebre punctu- 

 latis, tibiis anticis extus 7-denticulatis. Long. 4-5, lat. 2J-3 lin. 



This species is readily distinguishable from all the others known 

 to me of the Third Group by its frontal elevation being an elon- 

 gate carina reaching the hind extremity of the frontal margin on 

 either side, so that the frons is margined in every part by a well- 

 defined cariniform outline. I have seen enough specimens (14, 

 mostly taken by the Calvert Expedition) to justify the opinion 

 that both sexes are represented, but there is very little difference 

 that seems likely to be sexual. About 6 of the specimens are 

 considerably smaller than the rest and of lighter colour, with 

 their pronotum a little more punctulate; I take these specimens 

 to be of sex different from the others. The presence of 7 distinct 

 external teeth on the front tibise is an unusual character.
