 Type. Cat. No. 22S23, U. S. Nat. Mus. 



Described from seven specimens, two males and five females, 

 recorded under Bureau of Entomology number, Hopk. U. S. 

 10651p, and reared from material collected by Mr. F. C. Craig- 

 head, June 29, 1918, under bark on fallen limbs of Big Tree (Se- 

 quoia washingtonicino) . 



In general form this species resembles janthinum Lee., by hav- 

 ing the antennae apparently differing but little sexually, and the 

 median and lateral parts of the prothorax not separated by a 

 distinct line. It differs from that species, however, by having 

 the entire surface of a shining black color. 



Callidium juniperi, new species. 



Male. Form elongate, greenish cyaneous and strongly shining above; be- 

 neath, legs and antennae piceous black, shining with a slight metallic reflec- 

 tion; pubescence semi-erect, black and rather long on the head and pro- 

 thorax, almost wanting and extremely short on the elytra. Head coarsely, 

 deeply and confluently punctured over the entire surface; median line finely 

 impressed between the antennal tubercles. Antennae three-fourths as long 

 as the body; first joint not much thicker than the following joints; joints one 

 to four strongly incrassated at apex; second joint about one-half as long as 

 the third; tenth joint two-thirds as long as the eleventh, which is abruptly 

 pointed at apex. Prothorax moderately transverse, about as wide as the 

 elytra, one-half wider than long, widest at the middle; sides rather evenly 

 and strongly rounded, a little more rapidly converging to the base, which is 

 not subtubulate; surface with the punctures coarse, deep and close-set, be- 

 coming more rugose though only a little less shining at the sides; the abrupt 

 line separating the median and lateral areas not traceable. Scutellum broadly 

 rounded at apex; surface broadly concave. Elytra nearly four times as long 

 as the prothorax ; sides distinctly narrowing from base to the very broadly 

 rounded apices; surface coarsely, deeply and densely punctate throughout, 

 the punctures irregular and polygonally crowded, without well defined mar- 

 gins and with minute setose punctures in their depth; intervals shining, 

 nearly smooth, becoming a little more rugose towards the apex. Prosternum 

 very coarsely and deeply punctured, with a transversely and obtusely angu- 

 late rugose area before the coxae, and a narrow, nearly smooth area along 

 the anterior margin. Femora more gradually swollen than in C. pseiidot- 

 SHgae. Tibiae arcuate. 



Length 10 mm.; width 3.2 mm. 



Female. Differs from the male in having the antennae only a little more 

 than one-half as long as the body, with the last joint appendiculate. Pro- 

 thorax with the lateral areas more densely and finely punctate, the punc- 

 tures more confluent and less dtep than in the male. Prosternum very
