17. C. ectypa u. sp. 



This species resembles obesula so closely that the following differ- 

 ences only need be given : 



Surface distinctly a-neous. Aiiteniia; rufotestaceous at base, tlie five outer 

 joints piceous. Thorax distinctly alutaceous, the punctuation extremely fine, 

 indistinct and sparse, the basal marginal line consists of fine, closely placed 

 punctures. Anterior and middle femora brown, the posterior femora piceous, 

 tibife and tarsi rufotestaceous. Length .06 inch. ; 1.5 mm. 



(3ccurs at Los Angeles, C'aliforni;i, also in Arizona. 



18. C. pareepiinctata ("rotcli.— Oval, robust, surface »neous, shining. 

 Antenuffi rufotestaceous at base, piceous externally. Head finely alutaceous, 

 impunctate. Thorax nearly twice as wide as long, scarcely narrowed in front, 

 sides arcuate, basal marginal row of punctures distinct, but somewhat irregular, 

 disc indistinctlj' alutaceous or even smooth, the punctures fine, sparse and indis- 

 tinct. Elytra distinctly wider at base than the thorax, humeri rounded, umbone 

 moderately prominent and smooth, the striae not distinctly impressed, the punc-

 Abdomen sparsely and indistinctly punctate. Femora piceous, the tibiae and 

 tarsi brownish or rufotestaceous. Length .06 inch. ; 1.5 mm. 



As already stated this s|)ecies is closely related to m'lnuta in form, 

 size and color, the sculpture is also nearly identical, except that here 

 the head is iiu))unctate. As a rule the thorax here is more distinctly 

 punctate. 



Occurs in Mas.sachusetts (Blanchard), Pennsylvania, Maryland, 

 North Carolina, Florida and Texas.

 cuate, slightly obliquely truncate at the front angles, basal marginal line distinct, 

 closely punctured from the sides nearly to middle, surface distinctly alutaceous 

 and subopa(iue, the punctures fine, feebly impressed and sparsely placed. Elytra 

 a little wider at base than the thorax, humeri rounded, umbone smooth, distinct, 

 the striae faintly impressed, the punctures relatively coarse, closely placed, not 

 crenate, the intervals slightly convex, very little wider than the striae, surface
