NORTH AMERICAN COLEORTERA. 35 



and feebly piinctulate ; margin reflexed as in the protliorax, but nuicb 

 more narrowly and acutely. Dorsal surface of tlie last ventral segment 

 having three strong, posteriorly convergent, rounded carinae ; last segment 

 and the posterior two-thirds of the penultimate exposed. Legs short and 

 robust ; terminal joints of tarsi very slender, longer than the preceding joints 

 together. Length 3.1 mm. 



Arizona (Morrison). 



The reflexed margins of tlie pronotum and elytra render this a very 

 distinct and easily recognized species. 



Although T believe the type specimen to be a male, tiiere is no trace 

 of the additional ventral segment of the abdomen mentioned by Dr. 

 Horn in his revision of the Nitidulidce ; however, tiie formation of a 

 new genus seems scarcely warrantable. I see no mention of the very 

 distinct dorsal ridges of the last abdominal segment, in any of the 

 descriptions of the species of Carpophilus in the above-mentioned 

 work. 



EPURtEA. 



E. papagona n. sp. — Nearly twice as long as wide, moderately convex, 

 piceo-tlavate in color ; pubescence fine, moderate in length, evenly distributed, 

 recumbent, rather sparse. Head much wider than long ; interocular surface 

 very feebly and evenly convex ; labrum twice as wide as long, strongly and 

 acutely emarginate in the middle anteriorly ; eyes moderate in size, nearly 

 semicircular, coarsely granulated; antennae as long as the width of head, 

 third and fourth joints very slender, the former much the longer, fifth much 

 more robust, sixth slightly elongated, seventh sub-globular, eighth very 

 short and transverse, club very large, flattened, nearly one-third as long as 

 the entire antenna. Prothorax twice as wide as long, wider anteriorly than 

 the head ; sides moderately divergent posteriorly and evenly arcuate to a 

 point one-fifth the length from the base, where they become convergent and 

 strongly sinuate ; anterior and posterior angles prominent ; basal margin 

 transverse and nearly straight ; disk feebly and evenly convex, slightly 

 reflexed at the sides. Scutellum much broader than long, triangular. Elytra 

 at base as wide as the prothorax ; sides parallel and feebly arcuate for two- 

 thirds their length, then slightly convergent ; each elytron very obtusely 

 rounded behind ; disk rather strongly convex at the sides, feebly and nar- 

 rowly reflexed along the exterior edges. Legs moderate, of same color as the 

 body, somewhat slender ; last joint of the posterior tarsi as long as the first 

 two together. The prosternura is depressed behind the coxae, and prolonged 

 backward in a spatula-like process, which is wider than long and ciliate 

 posteriorly. The punctures of the entire dorsal surface of the body are 

 rather close, circular, clearly defined but very shallow, variolate ; the punc- 

 tures are uniformly setigerous. Length 2.5-2.8 mm. 



Arizona (Morrison). 



The sides of the pronotum are convergent and sinuate near the 

 basal angles to an unusual degree.
