CALLIDIADJE. 173 



(229) 5. Callidium (Merman) simile. Similar C. Merium. 



C. M. ( simile J nigrum, punctulatum, pilosum ,■ prothorace utrinque pulvinatum, minutissime et confertissime confluerder punctu- 

 latum ; elytris aneo-luridis, lineis duabus elevatis callosis pallidis confiuentibus, antennis apice fernoribusque rufis. 



Similar C. Merium, black, minutely punctured, hairy, prothorax pillowed out on each side, and most minutely and thickly 

 punctured with confluent punctures : elytra bronzed, lurid, with two elevated callous coalescing pale lines ; 

 antennas at the apex, and thighs, rufous. 



Length of the body 7 lines. 



A single specimen taken with the preceding species. 



DESCRIPTION. 



This species in most respects is so like C. M. Proteus, that I had set it by as another variety ; 

 but upon further consideration I am induced to give it as distinct, since it differs not only in colour 

 but in the form and sculpture of the prothorax and other parts. 



The apex of the palpi is more dilated, so that it is strictly securiform ; the front behind the 

 antenna? is elevated and gibbous, with few scattered punctures : the sides of the prothorax are more 

 puffed out, and much more minutely and thinkly punctured, and there is a pair of impressions in 

 the disk : the antenna? also at the base are rufous : in other respects it does not differ from M. 

 Proteus. 



(230) 6. Callidium (Merium) dimidiatum. Halved C. Merium. 



C. M. (dimidiatum) obscure rufum, supra nigrum ; elytris antice rvfis ; prothorace granulato, postice canaliculato. 



Halved C. Merium, obscurely rufous ; black above ; elytra rufous at the base ; prothorax granulated, channelled posteriorly. 



Length of the body 4 lines. 



Two specimens taken in Lat. 54°. 



DESCRIPTION. 



Body not glossy ; impunctured ; hairy underneath ; and except the forebreast, which is black, 

 of a dull rufous. Head channelled between the eyes, behind them convex ; antenna? rufous, shorter 

 than the body : prothorax somewhat coarctate at the base ; minutely granulated ; obsoletely chan- 

 nelled, more conspicuously behind : elytra rufous anteriorly. 



This species comes very near to C. (Merium) AM, but it is larger and has no white bands.
