In addition to the several characters given in the table, it may be 

 added that in this and the following species, the spines along the inner 

 edge of the basal joint of the hind tarsus are shorter and more close 

 set than in any other species known to me. 



C. fastidiosus sp. nov. 



Very closely allied to masculinus and possibly to be united with it as a local 

 variety when further specimens including males are known. The form is 

 a little less distinctly obovate, the prothorax larger, sides longer, just perceptibly 

 sinuate, and continuous with the sides of the elytra, feebly subexplanate, es- 

 pecially toward the anterior angles; not in the least so in masculinus. Length 

 4.7 mm. ; width 2.4 mm. 



A single female specimen collected at Owen's Lake, California, V-22- 

 17 by G. R. Pilate. 



C, semivittatus sp. nov. 



Moderately elongate, slightly obovate, pale flavotestaceous, the head and thorax 

 of slightly brighter tint and entirely immaculate; elytra each narrowly quadri 

 vittate with fuscous posteriorly, the two inner vittae on each extending to a 

 point a little in advance of the middle, the two outer ones represented only by 

 one or two short fragments, the suture also narrowly dark, surface (?) very 

 finely alutaceous and dull both above and beneath. Antennae with the outer 

 joints partly infuscate. Prothorax small, strongly transverse, sides nearly 

 straight, only slightly divergent posteriorly and not continuous in outline with 

 the elytra. Head and thorax very finely, not closely punctate, elytra densely 

 evenly so, almost without trace of coarser punctures. Length 4.5 mm.; width 

 2.2 mm. 



The unique female type was taken by the writer at Seligman, 

 Arizona, July 3, 1906. 



The four anterior tarsi are narrow, the first three joints elongate 

 parallel and of equal width. It is quite possible that further specimens 

 will show that the elytral vittae are not constant in their degree of 

 development. The somewhat obovate form and small thorax with 

 sides discontinuous in outline with the elytra, are quite suggestive of 

 masculinus, but the structure of the clypeus, prosternal process and 

 basal joint of hind tarsus are normal in the present species. 



C. hudsonicus sp. nov. 



Moderately elongate oval or feebly obovate, dull yellowish testaceous, head 

 more or less infuscate at sides, thorax witth small discal spot, elytra each with 

 four vittae and the suture piceous, body beneath black. Upper surface of male 

 finely reticulato-alutaceous and moderately shining, in the female more dis- 

 tinctly alutaceous and dull. Elytr-a evenly, rather closely punctate, coarser 

 punctures scarcely evident; head and thorax more finely and sparsely punctate 

 as usual. Beneath alutaceous and rather sparsely, not very coarsely punctate. 

 Front and middle tarsi of male broadly dilated, the second joint widest, the 

 claws more elongate than usual, the anterior one curved and a little shorter 

 than the posterior, which is nearly straight. In the female the claws of the 

 front tarsi are much shorter than in the male, and equal. Length 3.8 to 4 

 mm.; width 1.85 to 1.95 mm.
