256 GEO. H. HORN. 



Prosternum simple, mesosternum with a feebly elevated transverse ridge a 

 short distance in front of the coxae. 

 Claws similar in the sexes, slender, slightly broader at base. 



Motschulsky describes the species as having five or six strice, which 

 is correct enough, although it seems to me preferable to count only 

 the five that are well marked. In my previous essay this species is 

 placed as possibly identical with hnheUis Lee, but specimens were 

 then not known to me agi'eeing with the description. 



The specimens collected in the central and in the mountainous 

 regions have more distinct sculpture than those in the warmer re- 

 gions further south, where the specimens are much less deeply punc- 

 tate and generally smoother. 



Occurs from middle California southward into the peninsula of 

 'California. 



C iiiorata n. sp. — Oval, slightly oblong, not narrowed in front, moderately 

 convex, piceous shining, the entire border paler. Thorax moderately closely 

 punctate, less distinctly and more sparsely towai'd the sides, the arcuate and 

 transverse rows of coarser punctures scarcely evident. Elytra, near the ba.se, 

 punctured similarly to the thorax, near apex much more finely and sparsely, 

 almost smooth, the outer four strite moderately impressed and entjre. the punc- 

 tures rather coarse, but not denselj^ crowded, the inner striie very faintly indi- 

 cated and scarcely extending more than a third from the apex, sutural stria well 

 impressed and longer, coarser punctures of intervals 3-.5-7-9 well impressed. 

 Body beneath piceous opaque. Femora piceous, opaque, tibiie and tarsi rufo- 

 piceous. Length .20 — .24 inch.; 5 — 6 ram. 



Prosternum simple, mesosternum with a slightly elevated arcuate ridge slightly 

 in front of the coxse. 



Claws similar in the sexes, slender, feebly arcuate, slightly broadened at base. 



At first sight this species might be mistaken for dorsaUs, which it 

 resembles superficially in form and color. That species has, how- 

 ever, five entire striie, this but four, the interstitial coarse punctures 

 are very well marked here and scarcely evident in dorsalis. 



An immature specimen in my cabinet was formerly referred to 

 mibellis, and the number of entire stria? is the same in both species, 

 but in imbellis they are not impressed, and the punctures much finer. 

 The color is quite different in the two species also. 



Occurs in New Mexico near the Moqui Villages. 



C. imbellis Lee. — Oblong oval, scarcely narrower in front, moderately con- 

 vex, piceo-ochraceous or castaneous, with the border paler, head black, thorax 

 with a large piceous space extending from ajiex to base. Thorax closely punc- 

 tulate, punctures a little coarser and less dense toward the sides, the arcuate and 

 transverse rows of coarser punctures distinctly marked. Elytra less closely 

 punctulate than the thorax, the punctures a little coarser and less close toward
