 as long as broad.

Type ^ in the Stockholm Museum ; type of hohemani missing ; 

 type of intermedia in the British Museum. 



The 5 possesses a very distinct anal tubercle, whereas in the ^ 

 the last abdominal segment is plane, often with two patches of setaB 

 which make it appear shallowly depressed in the middle. The only 

 character by which hohemani, Boh., can be separated from sulci- 

 collis, Gyl., is that the thorax of the former is " intra basin trans- 

 versim profunde impressus." But this character is illusory, and can 

 be produced by loosening the thorax so as to expose the deep basal 

 constriction, which is normally hidden when the thorax fits closely 

 to the elytra. The type of intermedia, Pasc, agrees very closely with 

 the type of sulcicollis.

Long. 41-91; lat. 2i-4f mm. 



Colour extremely variable, but usually uniform grey or brown, the 

 elytra having a median sutural velvet-brown patch, which is deeply 

 excised posteriorly, and a similar smaller patch on each side of the 

 suture at the base. 



Head with remote shallow punctures, the frontal carinse absent 

 normally, but sometimes slightly developed. Bostrum shallowly 

 punctured, sometimes with a trace of a central carina near the base, 

 the dorsal margins rounded. Prothorax as long as broad, sides 

 scarcely rounded, broadest rather behind middle, constricted 

 anteriorly and with the ocular lobes slightly dilated laterally ; upper 

 surface reticulately punctured, with a central furrow which is usually 

 shallow and sometimes sub-interrupted in the middle, the anterior 

 transverse impression with a deep fovea on each side of the central 

 furrow ; sides with deep scattered punctures. Elytra ovate, 

 shoulders broadly rounded in V , often narrower and more oblique 

 in ^ , apical declivity rounded dorsally ; upper surface more or less 

 irregularly and reticulately punctured, the intervals 6, 4 and the 

 apical half of 2 with rows of subconical tubercles, which vary con- 

 siderably both in numbers and in elevation, those at the top of the
