die than the thorax, humeri distinct, sides feebly arcuate, surface striate, strife 

 moderately coarsely punctured, intervals flat, slightly wrinkled with a single 

 series of fine punctures. Body beneath with rather close intermixed punctuation, 

 the coarser punctures at the sides of the prothorax unusually coarse. Length .14 

 inch ; 3.5 mm. 



The antennfe in the unique before me are in part wanting, but from 

 the slender aspect of those present the entire number would extend 

 beyond the hind angles of the thorax. 



A smaller and more depressed species than any in our fauna. It 

 could only be confounded with dispersus by description, but is relatively 

 broader and more depressed, elytral intervals flatter and uniseriately 

 punctulate. 



One specimen, Florida. 



'El, bicolor Horn. — Form moderately robust, sparsely finely pubescent, shin- 

 ing, body beneath red, becoming piceous posteriorly, head and thorax red, elytra 

 black, antennae and legs rufo-testaceous. Antennae slender, not extending beyond 

 the hind angles of the thorax. Head sparsely, intermixed punctate, vertex with 

 vague depression. Thorax slightly longer than wide, sides straight and nearly 

 parallel behind, anterior third arcuately narrowing, disc convex, shining, sparsely 

 punctate, the punctures intermixed. Elytra very little wider than the thorax, 

 humeri distinct, sides feebly arcuate, disc rather deeply striate, strise punctured, 

 intervals convex in their entire length, slightly rugulose and sparsely punctate. 

 Body beneath with intermixed punctuation, not closely placed, the finer punctua- 

 tion scarcely distinct. Length .20 inch; 6 mm. 



A very distinct species by its color and deep elytral striation. 



Two specimens are known to me. That in my collection was given 

 me by Edward Tatnall, and said to have been collected in Delaware, 

 where he lived. As he made a journey to Florida there may be some 

 doubt, inasmuch as a specimen is in LeConte's cabinet collected by 

 Hubbard and Schwarz in Florida.

APTOPUS Esch. 



A. peregrin us n. sp. — Form of Cardiophorus convextis, rufo-testaceous, 

 brown or piceous, moderately shining, sparsely pubescent. Antennae as long as 

 half the body, feebly serrate. Head closely, rather coarsely punctate, front arcuate. 

 Thorax longer than wide, base slightly wider than apex hind angles feebly diver- 

 gent, sides very feebly arcuate, lateral margin without acute edge, hind angles with
