Mas. Latum; robustum; sat nitidum; supra glabrum; subtus 

 hirsutum; rufobruuneum; mandibulo sinistro (superne viso) extus 

 vix sinuato; capite (partibus extero-posticis exceptis) confertim 

 ruguloso; clypeo antice verticali; eminentia clypeali in medio ut 

 cornu breve obtusum elevata, ab hoc utrinque ut carina retrorsum 

 oblique ad marginem frontalem continua, cum hoc ut tuberculus 

 conicus utrinque conjuncta; eminentia frontali nulla; capitis parte 

 extero-postica utrinque concava fere Isevi; prothorace fere ut pr^e- 

 cedentis {B. tenacis, Blackb.) sed cornubus intermediis magis latis 

 magis parallelis magis porrectis et inter se magis distantibus et 

 parte postica linea longitudinali impressa; scutello Itevi; elytris 

 ut B. tenacis; tibiis anticis (exempli typici) carentibus; tibiis 

 posticis ut B. tenacis. Long. 11, lat. 1'i lin. 



This is another ally of B. armigerum, Macl., from which (and 

 from B. tenax, Blackb.) it differs by its clypeal (not frontal) 

 elevation being raised into a horn, the horn, moreover, being a 

 simple conical elevation like an exaggerated tubercle. The pro- 

 BOtum agrees with that of each of the abovenamed species in 

 having 4 horns placed more or less transversely, but differs by its 

 intermediate horns being parallel, very widely compressed (much 

 like the horns of B. laticorne, Macl.) and placed so as to project 

 straight forward; in ai^migei'iwi they are curved somewhat down- 

 ward, and in teriax somewhat upward. It is very much larger 

 than any example that I have seen of either armigeruin or tenax. 

 The unique specimen was given to me by Mr. Froggatt.
