NORTH AMERICAN COLEOPTERA. 97 



This 'species is uot likely to be confused with any others of its 

 series ; the prosternal lobe is here better marked than in any except 

 exem. 



Occurs in Colorado, Texas, Arizona and California. 



27. C. inali u. sp. — Form rather broad, subdepressed, color above variable 

 from dark bronze to bright coppery red, beneath more or less cupreous ; antennse 

 gradually more slender to tip, third joint as long as the next two, color greenish 

 in %, or dark bronze 9 ! front slightly convex in both sexes, very little more 

 closely punctured in the male and with two median callosities and a chevron 

 above ; clypeus (136) broadly triangularly emarginate at middle; thorax twice as 

 wide as long, narrowed at apex and base, widest slightly behind the middle ; disc 

 moderately convex, median line vaguely channeled and usually more densely 

 punctate, the surface otherwise densely, coarsely punctured with usually an ob- 

 lique callosity near the side ; elytra a little wider than the thorax, parallel, nar- 

 rowed at apical third, the margin serrulate, the apices obtuse ; disc with the 

 costje rather feebly indicated and with badly defined densely punctured spaces, 

 the first on the interval between the first and second costae, the second at the end 

 of the third costa (these often confluent) a third near the middle interrupting 

 the second costa, basal fovea rather feeble, the surface otherwise rather coarsely 

 not densely punctate ; body beneath rather sparsely, coarsely punctate, the ven- 

 tral segments with distinct lateral callosities; presternum with a short lobe in 

 front ; anterior femora with a prominent tooth, serrulate on its distal edge ; last 

 ventral segment with serrulate border, but without submarginal ridge. Length 

 .26 - .42 inch ; 6.5 - 10.5 mm. (Fig. 135.) 



Male. — Prosternum coarsely and closely punctate; anterior tibia (1391 arcuate, 

 abruptly dilated at apical fourth, the dilatation narrowing at tip ; middle tibia 

 arcuate, slightly thicker at tip, the posterior straight; last ventral segment (137) 

 semi-circularly emarginate, the last dorsal sparsely punctate and slightly emar- 

 ginate at tip. 



l^emaZe.— Prosternum a little less closely punctate ; anterior tibia slightly ar- 

 cuate, the middle and posterior straight; last ventral (138) with a small, semi- 

 circular emargiuation. the last dorsal sparsely punctate and truncate. 



Tlie variation in surface color is from the darker shades seen usually 

 in femorata to that with the entire surface quite red ; beneath the 

 difference Ls less marked. 



Specimens from the Sacramento Valley were sent me by Mr. L. 

 E. Ricksecker as infecting apple trees, others collected in Owen's 

 Valley could not possibly have had that habit. 



Occurs in California, Nevada, Utah and Colorado. 



28. C. pitsilla Lap. et Gory. — Form nearly as in the small specimens of 

 femorata, dark coppery bronze, slightly shining ; antennae gradually more slender 

 to the tip, bronzed in both sexes, third joint as long as the next two; front 

 slightly more convex in the female, punctuation rather coarse, a little denser in 

 the male, two small middle callosities in both sexes; clypeus (141) with a small 

 but broad emargiuation at middle, truncate each side ; thorax twice as wide as 

 long, narrowed at apex and base, but more abruptly in front, the sides at middle
