REVISION OF TENEBRIONID SUBFAMILY CONIONTIN^ IO5 



coarse, deep and less impressed, still coarser toward the sides; 

 prosternum finely but strongly, sparsely punctate, the process 

 broadly arcuato-truncate at tip, the beaded margin not extending 

 quite to the apex; hind femora rather strongly and distinctly 

 punctate, the abdomen very minutely and remotely punctulate. 

 Length 12.2 mm.; width 5.3 mm. Oregon (Medford), H. F. 

 Wickham proba n. sp. 



15 Side margin of the prothorax never more than slightly curved at 



base 1 6 



Side margin inflexed at base, extending along the basal margin 21 



1 6 Anterior canthus very full and broadly rounded 17 



Anterior canthus, because of the more oblique and straighter sides of 



the front, coming to a bluntly rounded point adjoining the eye.. 20 



17 Upper surface virtually glabrous, the hairs borne by the punctures 



very minute and inconspicuous 18 



Upper surface evidently clothed sparsely with short and decumbent 

 hairs 19 



1 8 Form subcylindric, strongly convex, strongly shining throughout, 



deep black, the legs and antennae dark rufous or piceous ; head 

 finely but strongly, closely punctate, the sinus broad, moderately 

 shallow, subparabolic, the anterior canthus broadly prominent and 

 but little less so than the posterior ; antenna* rather stout, com- 

 pressed ; prothorax two-fifths to three-fifths wider than long, the 

 anterior sinus circular, rather shallow, the sides strongly rounded 

 and converging before, becoming nearly straight and parallel be- 

 hind, the middle; surface finely but very strongly, distinctly and 

 closely punctate, still more strongly and closely though only a 

 little more coarsely so laterally, the beaded margin extremely fine, 

 curving at base about the hind angles only and then abruptly dis- 

 appearing; scutellum rather small, but little wider than long, 

 triangular, with the apex obtusely rounded ; elytra fully one-half 

 longer than wide, parallel, as wide as the prothorax, the apex 

 obliquely and arcuately narrowed, the extreme tip narrowly ob- 

 tuse ; surface very finely punctate, the punctures close-set in longi- 

 tudinally lineate areas separated by narrower and comparatively 

 impunctate lines ; side margin very finely reflexed ; under surface 

 and femora very minutely, sparsely punctulate. Length 8.7-10.0 

 mm. ; width 3.5-4.2 mm. San Francisco Co., Chas. Fuchs.

Form a little shorter and less cylindrical, smaller in size, convex, deep 

 black, with the legs rufo-piceous, the antennaa blackish-piceous ; 

 surface less shining, faintly alutaceous ; head finely, densely punc- 

 tate, nearly as in puncticollis but with the broadly rounded an- 

 terior canthus much less prominent than the posterior; prothorax 

 a little shorter, transverse, with the sides very feebly converging to 

 parallel from the base to the middle and usually nearly straight, 

 then more strongly convergent and moderately arcuate to the right
