Southern and Western States. Also related to the three preceding species, but inay be 
distinguished by the coarser and more sparse punctures of the elytra, and the more vague 
impressions. The thorax in my two specimens is scarcely wider in front, but I do not 
know if this will prove a constant character.

Three males; Saratoga, Mr. James Thomson. Differs from the smallest C. femorata 
by its still smaller size, and by the punctures, (especially of the elytra,) being irregularly 
diffused so as to leave occasional almost smooth spaces, and by the subsutural costa being 
undulated towards the tip of the elytra; the impressed spots are, as in the species men¬ 
tioned, a transverse anterior fascia, completed by a subsutural spot, anterior to its main 
direction, and a posterior sinuated band.

Santa F4, New Mexico, Mr. Fendler. Robust, depressed, dull bronze, head very densely 
punctured, with two smooth spots between the eyes, and an occipital bifurcating line; 
front coppery; labrum green; antennae green; third joint as long as the two following; 
thorax twice as wide as its length, rounded on the sides, deeply lobed at base; dorsal 
groove deep, densely punctured, sides rugosely punctured, with a large longitudinal callus 
extending from the tip nearly to the base, and a broad, shining, nearly smooth costa, 
contiguous to the dorsal groove. Elytra wider than the thorax, obliquely narrowed and 
finely serrate behind, then sparsely rounded at the apex; subsutural costa entire, gradually 
dilated towards the base, second costa reaching nearly to the tip, dilated at one quarter 
the length so as to join the third, and again more broadly behind the middle so as to touch 
the subsutural, then slightly interrupted; third, slender, interrupted behind, and confluent
