the head, antennae (except the club), entire ventral surface of 

 body and the legs are red, the pubescence of the parts is red ; 

 the mandibles, antennal club, tips of tarsal appendages and 

 the tarsal claws are black. Vestita is a very broad species, 

 the width equaling half the length. 



Examples from the more tropical portions of its habitat 

 show this to be a variable species in coloration, the tendency 

 being for the bluish portions to become obscurely reddish and 

 the pubescence more dense. In a Guatemalan specimen in 

 my collection the elytra are violaceous, the prothorax dull 

 aenous "with a reddish tinge, the tarsi entirely red, and the 

 mandibles black at tip only ; the five apical joints of the an- 

 tennae black, the pubescence of thorax and elytra fulvous and 

 the velvety black spots of the elytra very large and round.

This species bears a slight resemblance to C. dichroa, but 

 differs from it in many respects. Elegans is a much broader, 

 more depressed species. It is a deep sanguineous red (the color 

 fading in old material to a pale red, as described by Dr. Horn), 

 the elytra blue with metallic lustre wanting ; the antennae 

 (the basal joint excepted) and the tarsi black. The prothorax 

 in this species is much more coarsely and densely punctured 

 while the elytra are less coarsely punctured than in dichroa.

This species may be easily recognized by its elongate form, 

 finely punctured thorax and coarsely punctured elytra. The 

 coloring in this species is the same as in C. elegans, with the 

 following exceptions : the blue of the elytra has a sub-metallic 

 lustre, the prothorax is more shining, the legs and antennae 

 are entirely black, while the scutellum is red, the pubescence 

 of the head and prothorax is blackish. 



Dichroa is by far the rarest species and according to Mr. 

 Hopping the larvae of the two species seem to be indistin- 

 guishable. Both species breed in the same log that of Out-rats 

 douglasii or Sierra foot-hill oak (at Kaweah, Cal.), and as this 

 oak does not grow much above 2000 feet, Mr. Hopping thinks
