6. C Stigniaficus Gaud.— Robust, or the males frequently small and more 

 slender, black or lead black, opaque with cinereous or yellowish, sometimes 

 coarser pubescence; elytra four spotted or bifasciate with yellow. Antenna- 

 black, not stout, serrate, longer than the head and thorax in the %, , shorter and 

 more slender in the 9. Head densely punctate, with sparser, coarser punctures 

 intermixed. Thorax densely less coarsely punctate, coarser punctures sparsely 

 intermixed, sides rounded, somewhat obliquely narrowed behind, as wide as long 



%, wider than long 9, basal plicaj moderate, hind angles obliquely truncate 

 above, produced beneath, the carina not joining the submarginal behind, basal 

 lobe rather broadly emarginate, Insinuate, the median tooth scarcely evident. 

 Elytra a little wider than the thorax, with the sides rounded and rather more 

 suddenly narrowed at apex than in the last, punctato-striate, intervals rather 

 densely punctnlate. flat, a median and posterior yellow spot or fascia. Body be- 

 neath, rather strongly punctulate, not closely on the prosternum, closely on the 

 flanks, becoming coarser and confluent behind, the hind margin of the fourth 

 and the fifth ventral coarsely and densely punctured, intercosal process of the 

 prosternum very short and strongly ascending, not margined behind, hind coxal 

 plates narrowed externally, angles rounded. Legs black or piceous, varied with 

 rufous. Length .■20-.30 inch ; 5-7 mm. 



California. 



The larger measurement is of a veiy robust 9 coai-sely and 

 densely punctured beneath and with four small spots on the elytra. 



7. C piillus n. sp.— Small, narrow, very convex, black, rather shining, tibia:- 

 and tarsi pale. Antennai black, serrate, the second joint more than one half as 

 long as the third, joints 3-6 wider, less than twice as long as wide, outer joints 

 a little narrower. Head feebly convex, impressed before the vertex and behind 

 the frontal margin, which is strong, slightly depressed and subangulateeach side 

 at middle, the lateral oblique carina evident, but not marked, rather coarsely 

 and closely punctate. Thorax a little longer than wide, very convex, sides 

 rounded and moderately narrowed in front and behind to the carina, then ob- 

 liquely a little more narrowed to the tips of the hind angles, a median linear 

 impression faintly evident from before the middle, deeper behind, ba,se strongly 

 impressed each side, lobe broadly emarginate, more elevated at middle, plicte 

 rather long and well marked, carina distinctly ending inside of and before the 

 apex of the angle, strongly and rather sparsely punctulate on the disc and base 

 with scattered coarser punctures, more densely in front and on the sides. Elytra 

 slightly wider, sides subparallel, rounded and narrowed from behind the middle 

 to tip, which is rather narrow and subacute, very strongly striate, the punctures 

 moderate, rather closely placed, but not deeply impressed nor very evident, in- 

 tervals very convex, strongly not densely punctnlate, with irregularly placed, 

 fine, transverse lines or wrinkles, giving the intervals a somewhat finely rugose 

 apiiearancc. Body beneath with flanks of prothorax rather strongly and sub- 

 confluently finely i)unctate, with sparser coarser punctures evident, prosternum 

 feebly inijji-essed at middle, more shining, sparsely and strongly punctulate, with 

 a few .scattered punctures, posterior process short, not margined behind, dis- 

 tinctly, not very strongly ascending, lateral submarginal lines cariniforin, feebly 

 curved, extending from apex of hind angles above to before the middle, base 

 feebly sinuate inside the anole, metasternum and abdomen rather strongly punc-
