NORTH AMERICAN COLEOPTERA. 75 



4. C. clebilis Lee. — Form moderately elongate, slightly convex, dark brown- 

 ish bronze, sometimes slightly feneous, sides of thorax usually broadly, bright cu- 

 preous ; antennse bright cupreous % or piceous 9 > gradually more slender to the 

 tip, the third joint as long as the next two ; front slightly convex, densely punctate, 

 more finely and more distinctly pubescent in the male, two distinct callosities, the 

 occipital carina sometimes bifurcate on the vertex ; clypeus with a moderately deep 

 oval emargination at middle arcuate each side ; thorax one and a half times as wide 

 as long, the base slightly narrower than the apex, the sides arcuate, broadest at 

 apical third, disc moderately convex, surface regular, without median or other 

 grooves or callosities, the punctuation a little variable, usually not dense, some- 

 times indistinct, but with distinct transverse strigse ; elytra a little wider than 

 the thorax, parallel, narrowed at apical third, the margins serrulate, the apices 

 obtuse ; first costa elevated near the apex, the others indicated by smooth lines, 

 more or less distinct, and usually interrupted ; basal fovea distinct but not deep, 

 two fovefe at apical third sometimes confluent, another in front of middle on the 

 second costal line, surface moderately closely punctured, more densely near the 

 base ; body beneath dark bronze, rather densely punctured, the sides of the ven- 

 tral segments densely and finely punctured and rather densely clothed with 

 white pubescence, the middle of the segments more coarsely and sparsely punc- 

 tured, a narrow space on each side of sutures two, three and four smooth and 

 shining; prosternum with a well defined lobe in front; anterior femur with a 

 moderately large, serrate tooth ; margin of last ventral segment serrulate. 

 Length ,20 -..32 inch : 5-8 mm. (Fig, 15.) 



Hale. — Prosternum flat, densely, finely punctured and pubescent ; anterior 

 tibia (19) arcuate and with a short dilatation at apex ; middle and posterior tibiae 

 straight; last ventral segment (17) senii-circularly emarginate ; last dorsal 

 coarsely punctate, triangularly emarginate at apex. 



Female. — Prosternum flat, more coarsely punctured and less pubescent than the 

 male; anterior tibia slightly arcuate, the middle and posterior straight; last 

 ventral (18* truncate, slightly emarginate; last dorsal coarsely punctate, entire. 



While this species is rather inconspicuous in appearance it is as 

 easy to recognize as any in our fauna by the very well defined pros- 

 ternal lohe, the densely finely punctured sides of the abdomen with 

 the white pubescence and the elytral sculpture. I have examined 

 the types of debilis and dl^jnncta and find no appreciable difference. 

 They were originally described from uniques, but I have recently 

 examined more than twenty specimens. The elytral foveas are often 

 consjiicuously cupreous ; in the majority of specimens not so. 



Occurs in Ohio (LeConte), Texas, Arizona and southern California. 



5, C axillaris n, sp, — Form moderately elongate, not very convex, nearly 

 as in debilis, but broader ; color dark brownish bronze, the basal fovea of the 

 elytra and large humeral space, bright coppei-y red ; autennse more slender to the 

 tip, piceous, second joint as long as the next two ; front very slightly convex, 

 coarsely, closely punctate, two small tuberosities and a feeble chevron above ; 

 clypeus with a moderately deep oval emargination, arcuate each side ; thorax 

 twice as wide as long, base and apex equal, sides slightly irregularly arcuate, disc 

 moderately convex, without depressions or callosities, the surface rather sparsely
