hairs. The gular area is deeply rugosely punctate, and 

 bears a bush of long black hair. The front of the proster- 

 num shows some deep rugae. The second joint of the 

 antennae is elongate, about as long as the first joint. The 

 third joint of the tarsus is very little emarginate. Struc- 

 ture of labrum not definitely ascertained. The species is 

 no doubt quite distinct ; it looks like the North American 

 G. agrestis or productus, but appears to be nearer to C. fcrus, 

 notwithstanding the intense black colour of the male. 



Hab. North Chin Hills, Burma. Lieut. Watson in 

 1894. 



Criocephalus agrestis, Kirby. 



Augustus, sat elongatus nlger, elytris fusco-nigris ; prothorace 

 bi-impresso ad latera vix angulato ; elytris bicostatis, inter costas 

 subtilissime sculpturatis. Long. 18£ mm., lat. 5 mm. 



This North American insect in the male sex greatly 

 resembles C. fcrus; it is rather more slender and shining, 

 and has a smaller thorax, which has a very slight angular 

 prominence at each side of the middle. I can give no 

 information as to the distribution of this species in North 

 America. 



Criocephalus productus, Lee 



Gracilis, elongatus, niger, elytris maris dilutioribus ; prothorace 

 haud transverso, disco inaequali, tri- vel quadri- impresso, ad latera 

 subangulato ; elytris elongatis, costatis, inter costas crebre perspicue 

 punctatis. Long. 20-26 mm., lat. 4£, 6| mm. 



Readily distinguished from G. agrestis by the more 

 elongate form, the less transverse thorax and the more 

 developed sculpture of the elytra. The sculpture of the 

 gular area consists of fine rugosities, and there is not much 

 beard. 



Hab. N. America. 



The species is, I believe, not uncommon in N.W. North 

 America. I have specimens from Montana {Morrison) ; 

 Vancouver (Matheiv) ; California (Hepburn). 



Criocephalus asperatus, Lee. 



Latior, robustus, niger, elytris interdum dilutioribus ; prothorace 

 disco inaequali, ad latera numerose muricato-asperato, lateribus angu- 

 latim prominalis ; elytris bicostatis, sculptura inter costas obsoleta ; 

 anteimis articulis ultimis quatuor abbreviatis. Long. 21-27 mm.,
