head and elytra are also alutaceous, the former unusually coarsely and closely 

 punctate, the elytra as a rule rather sparsely and finely punctate, but more 

 coarsely so than the prothorax. The color is very variable. In the type the 

 head and prothorax are black, the latter with side margins pale, very narrowly 

 so at middle, more broadly so at the angles ; elytra each with broad bluish black 

 vitta, narrowed at basal third, the sutural, apical and lateral margins almost to 

 base, pale ; venter black ; femora black, tibiae and tarsi pale. The prothorax 

 varies from entirely black to entirely pale, the elytral vittse may be black, 

 bluish or greenish and are often completely interrupted; in one example in my 

 collection from Santa Rosa, Cal., the prothorax and elytra are entirely black ; 

 the legs vary to almost entirely black. Several names have been given to color 

 varieties and others might be given with equal propriety — or lack of it. 



Var. insulatus Lee. Smith. Miscel. Coll., 1865, p. 94. 



Elytra quadrimaculate, prothorax rufous with broad median black stripe. 

 The type is considerably above the average size (4 mm.) but I have seen very 

 similar smaller examples. 



The t3'pe is from California; a second example in the LeConte 

 cabinet is from New Mexico; I have seen it also from the Santa 

 Rita Mts., Arizona. 



Var. utahensis Schaef. Can. Ent., 1912, p. 187. 



This is insulatus with the prothorax entirely black. 



The type is from South Creek, Beaver Co., Utah. It is known to 

 me also from St. George and Nephi, Utali, and from " Col." and 

 Rifle, Col. 



Var. texanus Schaef. Can. Ent., 1912, p. 187. 



This again is insulatus with the prothorax entirely rufous. The type is 

 from Brownsville ; it has also been taken by Professor Wickham at Tucson, 

 Arizona. 



The species is quite widely distributed in the southwest, occurring 

 from "Missouri Territory" (type) and Brownsville, Texas, to Cali- 

 fornia. The following specific localities are known to me : Texas- 

 Brownsville, El Paso; New Mexico — Las Cruces ; Arizona — Santa 

 Rita Mts., San Bernardino Ranch, Tucson ; Colorado — Rifle ; Utah — 

 Clear Lake, St. George, Nephi, South Creek; Nevada — Sutro; Cali- 

 fornia — Santa Rosa, Pasadena, Pomona. 



C. validus Horn. Trans. Am. Ent. Soc, 1870, p. 82. 



Our largest species, and unapproached in size by any other of ours with 

 maculate elytra except the larger specimens of balteatus. The size, together 

 with the bimaculate prothorax and entirely pale legs, are entirely characteristic. 

 With the exception of scutellatus and certain specimens of pulchellus all other 

 species of this group have the legs, at least in part, black.
