Callidium pseudotsugae, new species. 



Male. Oblong, dull black throughout above; beneath, legs and antennae 

 shining black, with a faint bluish reflection; parallel; pubescence erect, black 

 and bristling from the head and prothorax laterally, almost wanting and 

 extremely short on the elytra. Head coarsely and confluently punctate, 

 punctures coarser and more distinct between the eyes; median line finely 

 impressed. Antennae as long as the body; first joint twice as thick as the 

 following joints and two times as long as the second; joints one to four strongly 

 incrassated at apex; second joint a little more than half as long as the third; 

 tenth and eleventh joints sub-equal in length; last joint rather broadly 

 rounded at apex, not appendiculate. Prothorax transverse, two-fifths wider 

 than long, slightly wider than the elytra, widest at about the middle; sides 

 strongly, evenly rounded, rather roundly converging towards apex, more 

 rapidly converging and rounded from a little behind the middle to the very 

 fainty subtubulate base; surface with the lateral parts very densely and 

 deeply punctured and separated from the median impressed part, with coarse 

 but very shallow punctures, by a well defined and abrupt line, which has a 

 well marked sinus just behind the middle. Elytra three and one-half times 

 as long as the prothorax; sides parallel, obtusely rounded at apices; surface 

 alutaceous, coarsely irregularly punctured, margins of punctures indefinite, 

 with minute setose punctures in their depth. Scutellum nude, very ob- 

 tusely and broadly ogival; surface broadly concave. Prosternum densely 

 and deeply punctured over entire surface, similar to the lateral part of pro- 

 thorax. Beneath moderately punctured and sparsely clothed with long erect 

 blackish hairs. Femora strongly swollen. Tibiae arcuate. 



Length 10-13 mm.; width 3.5-4.5 mm. 



Female. Differs from the male in having the antennae only two-thirds 

 as long as the body. Prothorax as wide as the elytra with the median part 

 not impressed and the entire surface uniformly punctured with coarse but 

 very shallow punctures. Prosternum finely, sparsely and transversely punc- 

 tato-rugose, shining. Femora and first antennal joint not as strongly swollen 

 as in the male. 



Length 10-12 mm. ; width 3.5-4.5 mm.
