scarcely longer than the head and prothorax, moderately incras- 

 sate toward tip; basal joint cylindric, perceptibly longer and 

 thicker than the second, the latter ovo-cjdindric, | longer than 

 wide, thicker and much shorter than the next two ; third f longer 

 than wide ; third to eighth gradually increasing in thickness and 

 decreasing in length, the eighth subglobnlar ; ninth to eleventh a 

 little more rapidly but gradually and almost continuously incras- 

 sate ; ninth and tenth moderately transverse ; eleventh gradually 

 pointed, as long as the preceding two. Prothorax subquadrate, 

 scarcely as long as wide, fully |- wider than the head, moderately 

 dilated, parallel and rounded laterally toward apex, the sides per- 

 ceptibly convergent and broadly, feebly sinuate thence to the base ; 

 surface evenly convex, feebly and confluently biimpressed near the 

 base at the middle, the lateral fovea large and distinct, the lateral 

 edge acute near the fovea, becoming more obtuse again at the 

 base. Scutellum moderate in size. Elytra minutely and sparsely 

 punctulate, elongate-oval, strongly convex, ^ longer than wide, 

 2^ times as long as the prothorax and fully f wider, the sides 

 broadly, evenly arcuate, gradually and continuously rounding and 

 convergent to the base of the prothorax, the humeral plica short 

 and only moderately prominent ; subhumeral impression short, 

 the inner long and strong ; subsutural impressions obsolete, the 

 suture minutely elevated toward base. Abdomen convex, sparsely 

 but strongly pubescent, the last two segments longer but together 

 shorter than the first four, the sixth parabolic, with a small exca- 

 vation at the apex. Legs long and slender, the femora very 

 feebly dilated toward tip, the anterior more distinctly ; hind tarsi 

 long and slender, with the basal joint as long as the next two, the 

 anterior stouter toward base and clothed beneath with long pale 

 hairs. Length 1.9 mm. ; width 0.62 mm. 



Queen Charlotte Islands (Massett — Mr. J. H. Keen), Sitka — 

 Mannerheim and California — Motschulsky (possibly in error). 

 This distinct species may be identified immediately by the very 

 deep and conspicuous excavations of the head ; the rather large 

 and very profound excavation above each eye was not observed 

 by either Mannerheim or Motschulsky. 



The two specimens sent to me by Mr. Keen are evidently 

 males, but there are no visible crural modifications. The exca- 

 vation at the base of the head will prove to be perfectly asexual, 

 though the pits above the eyes, and particularly the tumidity of
