156 PROC. ENT. SOC. WASH., VOL. 22, NO. 7, OCT., 1920 



Snyder on freshly cut branches of Douglas fir (Pseudotsuga taxi- 

 folia). In the collection there is also a specimen labeled "Oregon, 

 Coll. Hubbard & Schwarz," and another labeled "Santa Clara 

 Co., Cal., Collection Coquillett." 



This species falls in the group where the antennae differs con- 

 siderably in length in the sexes and having the line separating the 

 median and lateral parts of the prothorax well marked. It is 

 closely allied to antennatum Newm., but differs from that species 

 by having the upper surface entirely black. 



Callidium sequarium, new species. 



Male. Oblong, black throughout above, shining, parallel, pubescence 

 "erect, black and bristling from the head and prothorax laterally, almost 

 wanting and very short on the elytra. Head coarsely and densely punctured 

 over entire surface; median line slightly impressed in some specimens, absent 

 in others. Antennae two-thirds as long as the body; first joint not quite 

 two times as thick as the following joints; joints one to four strongly incras- 

 sated at apex; second joint half as long as the third; joints ten and eleven 

 about sub-equal in length ; last joint broadly rounded at apex, not appendicu- 

 late. Prothorax not quite as transverse as in pseudotsiigae, narrower than 

 the elytra, one-fourth wider than long; widest just in front of middle; sides 

 strongly rounded, roundly converging towards apex, more rapidly converg- 

 ing and rounded from about the middle to the base, which is not at all con- 

 stricted or subtubulate; surface coarsely, deeply and closely punctate, the 

 punctures becoming deeper and more rugose, although only a little less 

 shining, at sides; the abrupt line separating the median and lateral areas 

 scarcely traceable. Elytra three and one-half times as long as the prothorax; 

 sides parallel, obtusely rounded at apices; surface very coarsely, deeply and 

 densely punctate, the punctures distorted and without well defined mar- 

 gins, the minute setose punctures in their depths not as well defined as in C. 

 pseudotsugae. Scutellum broadly and obtusely ogival, surface coarsely punc- 

 tate. Prosternum very coarsely and deeply punctured, with a transversely 

 and obtusely angulate rugose area before the coxae, and another similar 

 area along the anterior margin, the punctures distinctly separated and well 

 defined. Beneath black without any bluish reflections, shining; surface mod- 

 erately punctured and sparsely clothed with long semi-erect hairs. Femora 

 strongly swollen. Tibiae arcuate. 



Length 11 mm.; width 3.5 mm. 



Female. Differs from the male in having the antennae only one-half as 

 long as the body with the joints not quite as strongly swollen. Prothorax 

 with the densely punctured lateral area more shining, the punctures finer, 

 more confluent and less deep. Prosternum very finely, sparsely and trans- 

 versely punctato-rugose, shining. Femora not as strongly swollen as in the 

 male. Tibiae scarcely arcuate. 



Length 11-12 mm.; width 4-4.5 mm.
