NORTH AMERICAN COLEOPTERA. 93 



. 22. C califoriiiea Lee. — Form very like trinerria, but rather more de- 

 pressed and broader ; color dark cupreo-seneons, sometimes slightly greenish, 

 beneath rather brassy, sometimes slightly greenish ; antennae greenish % or 

 cupreous 9) gradually more slender to the tip, the third joint as long as the 

 next two ; front flat, greenish, more densely punctured and slightly i)ubescent % , 

 slightly convex, seneous, more coarsely punctured f ^md with two indistinct 

 callosities in both sexes; clypeus (111) with a broadly oval emargination at mid- 

 dle, arcuate each side; thorax twice as wide as long, narrowed at apex and base, 

 the sides at middle often slightly sinuate ; disc moderately convex, a median, 

 broad, densely punctured sulcus limited each side by a broad elevated space 

 which is smooth in front and very coarsely punctate posteriorly, two oblique 

 callosities near the side, the surface otherwise densely and coarsely punctate : 

 elytra a little wider than the thorax, parallel, narrowed at ajiical third, the mar- 

 gin feebly serrulate, the apices obtuse ; disc with the first costa entire, hut less 

 elevated and liroader near the base, the other co.sta interrupted, the third quite 

 oblique, often joining the second at middle, the intervals between the costse with 

 alternating smooth and punctured spaces, the punctuation dense or sparse in 

 places, the basal depressions rather feeble ; body beneath coarsely but sparsely 

 punctate, the ventral segments with distinct lateral callosities; prosternum (99) 

 with a short, broad lobe in front ; anterior femur with a moderate tooth, serru- 

 late externally ; last ventral segment serrulate at the sides and with a feeble 

 submarginal elevation. Length .40 -.76 inch; 10 -19 mm. (Fig. 110. J 



Male. — Prosternum densely punctate, spar.sely pubescent ; anterior tibia (114) 

 flexed at apex and base and with a nearly semi-circular dilatation at apical 

 fourth ; middle tibia slightly arcuate and gradually broader at apical third, the 

 posterior straight; last ventral .segment (112) deeply semi-circularly emarginate, 

 the last dorsal coarsely punctate, acutely notched at middle. 



Female. — Prosternum more convex, more coarsely and not densely punctured ; 

 anterior tibia feebly arcuate, the middle and posterior straight; last ventral (113) 

 subtruncate at apex, the angles acute, last dorsal crihrately punctured with a 

 slight notch at tip. 



This species seems to vary more in size than in any of those with 

 the sculjiture of the style of trinervia, and its smaller forms greatly 

 resemble some of those, especially caurina, and for its separation the 

 presence of the prosternal lobe, although feeble, and the sexual char- 

 acters Avill suffice. 



With this species I have united vulcanica Lee. as a smaller form. 



Occurs in the northern part of California and in Nevada. 



23. C". BIancliar<li n. sp.— Form nearly as in dentipes, hut less depressed, 

 surface above very distinctly bronzed, beneath similar in color but more shining ; 

 antennffi % greenish, O bronzed, gradually more slender to the tip, third joint 

 as long as the next two ; front flat, green, densely punctured and pubescent % , 

 or slightly convex, coarsely and less densely punctured 9 - with two callosities 

 less strongly indicated 9 ; clypeus (115) broadly but not deeply triangularly 

 emarginate ; thorax twice as wide as long, narrowed at apex and base, the sides 

 almost regularly arcuate, disc feebly convex, a vague, median, densely punctured 

 sulcus, with a slightly elevated, less punctured space each side, a vague, oblique.
