 Allied to C. nodicollis, Bourg., but differing from it, inter alia, 

 by the markings of the elytra much more widely than my obser- 

 vation of a good many specimens of Calochromus allows me to 

 think compatible with mere colour variety. The elytra of 

 C. nodicollis are described as being entirely ochraceous except a 

 narrow basal border, while in the present species their marking 

 consists of a large common patch touching the base but not quite 

 reaching to the lateral margins and extending hindward to the 

 length of two-thirds of the elytra and slightly narrowing towards 

 its apex, so that the red margin gradually widens slightly from 

 its base and the apical one-third of the elytra is entirely red. 

 Thus the black patch bears a rough resemblance to a hood 

 thrown back over the elytra from their base. This marking seems 

 constant. There are various details in which this insect departs 

 otherwise from the description of C. nodicollis ; inter alia the 

 interstices of its elytral cos tee are said to be rugose whereas in 

 the present species they are excessively finely granulated, — 

 scarcely more than coriaceous, and nodicollis is said "to a casual 

 inspection to remarkably recall G. scutellaris, Er.," whereas the 

 present insect is a much more robust species of considerably 

 wider form with very much longer antennae. The measurements 

 of G. nodicollis make it fully three times as long as wide ; 

 C. cucullatus is distinctly less than three times as long as wide. 

 Of the other previously described Galochromi, none seem to have 

 the remarkable clypeal sexual characters of this species, — some 

 have the prothorax bicolorous (very remarkably so in C .brevicornis, 

 Lea, and pilosicornis, Lea, in which the prothorax is said to be 

 "yellow tinged with red," - and those having a black prothorax 

 (even if the clypeal sexual characters have merely been over- 

 looked in the descriptions, — as may be the case in one or two 

 that I have not seen) present strongly marked differences that 

 make this species very distinct.
