terior tarsi even more feebly dilated than usnal, with the papillae 

 of the under surface rather coarse and only moderately dense, the 

 pad of the first joint small and apical. It agrees quite well with 

 the figure of Motschulsky, but is probably not a very character- 

 istic specimen, as the elytral intervals are almost entire. The 

 form figured by Motschulsky under the name ventricosus, which 

 is referred to this species by Dr. Horn, is certainly quite different, 

 but it is probable also that it does not represent ventricosus ; it 

 is wholly indeterminate fi'om the figure. 



33. B. cupripennis n. sp. — Elongate, feebly ventricose, shining fehrotigli- 



out, black, the elytra bright metallic cupreous-red, with a brilliant green 

 margin; legs and under surface piceous. Head moderately stout and elongate, 

 triangular, the gense very feebly developed and having an exceedingly small 

 angular nick; supra-orbital ridges very fine posteriorly, moderately strong at 

 the antennse, the latter slender, scarcely % as long as the body, with the basal 

 joint notably thicker and nearly as long as the next two, the seta at apical 

 seventh or eighth ; vertex nearly smooth. Prothorax relatively rather well de- 

 veloped, about as long as wide, moderately dilated and rounded anteriorly, 

 the sides more strongly rounded well before the middle, thence oblique and 

 almost straight to the base, the angles much more than right and bluntly 

 rounded; base fully ^2 the maximum width and as wide as the head; disk 

 feebly convex, the median line rather deeply impressed; sublateral longitudi- 

 nal impressions distinct, extending before the middle; reflexed margins mod- 

 erate. Elytra evenly elongate-elliptical, nearly y^ longer than wide, 3 times 

 as long as the prothorax and scarcely more than 2^4 times as wide, obliquely 

 and evenly rounded and not very full at the humeri ; reflexed margins ample, 

 with very coarse punctures; disk evenly and moderately convex, the striae 

 ■coarse, slightly uneven, broadly impressed, deep laterally but rather shallow 

 toward the suture, the punctures coarse, uneven and close-set; intervals con- 

 vex, but slightly uneven at the sides. Femora stout. Length 15.0 mm.; 

 width 6.0 mm. 



Washington State. 



The two males before me represent a species allied to margina- 

 tus but slightly larger, and differing greatly from that, and all 

 other forms of the present group, in the thicker femora and much 

 more dilated anterior tarsi. The intercoxal plate of the meso- 

 sternum is rounded, flat, with abruptly elevated and rather fine 

 side margins and the usual large posterior emargination. 



34. B. insularis n. sp. — Elongate, rather feebly ventricose, shining 

 throughout, black throughout the body and legs, the elytra rather dusky 

 cupreo-violaceous, with narrow and bright aeneous side margins. Head rather 

 stout, moderately elongate, the vertex almost smooth, the broadly impressed 

 transverse nuchal constriction rather pronounced ; gense feebly developed, with
