MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARIA. 391 
Small, rather short, subdepressed, scarcely shining, finely punctate and thinly griseo- 
pubescent, deep testaceous. Head rather large, densely and finely punctate, slightly 
impressed on each side in front. Thorax narrowed in front, with the sides nearly straight, 
emarginate at the apex, truncate at the base, with the anterior angles nearly right 
angles and the posterior angles acute ; densely and finely punctate, with the lateral mar- 
gins distinct and reflexed. Scutellum broad, subpentagonal, thickly punctate. Elytra 
broad, a half longer than the thorax, closely faintly punctate, with the apex edged with 
black or brown, the lateral margin distinct and reflexed; apex of each elytron obliquely 
truncate; exterior apical angles sharply rounded. Abdomen finely punctate. 
This species has a good deal of the short broad form of C. antiquus, and was mistaken 
by Melsheimer for a variety of it. It is not shining likethat species, but has considerable 
affinity to it, and should perhaps have been placed beside it rather than here. j 
From Carolina and other southern districts of North America.

Leconte, in Proc. Acad. Nat. Sc. Philad. March 1858, p. 62 (1858). 
Forsan mas C. caudalis, Leconte, loc. cit.: vide C. CAUDALIS, ante. 
Oblongus, fere depressus, piceus, nitidus, subtiliter pubescens, elytris macula testacea 
triangulari, postice truncata, antice attenuata, utrinque ornatis; pedibus antennisque 
rufis, his clava paulo infuscata. Long. 3% lin. 
Habitat apud flumina Colorado in California. / 
Oblong, almost depressed, piceous, shining, finely pubescent ; antennz rufous, with a 
fuscous club. Thorax short, sides rounded, more faintly punctate. Elytra twice as long 
as the thorax, more strongly margined and more faintly punctulate, with a testaceous 
patch of a triangular form, truncate behind and attenuated in front on each side. Legs 
rufous. 
Somewhat allied to C. marginatus, Er., but larger, more regularly oblong, and more 
flattened. Dr. Leconte suggests that it may be the male of C. caudalis, which in every 
respect corresponds with it except in having three segments of the abdomen exposed 
instead of two. 
Found near the Colorado River in California. In Dr. Leconte's collection. 
89. CARPOPHILUS USTULATUS. 
Parvus, elongato-ovatus, depressus, sat nitidus, levissime punctatus, ferrugineus, elytris 
apice late indeterminate nigro-fusco. Long. 1 lin., lat. $ lin. 
Habitat in Nova Guinea. i 
Small, elongate-ovate, depressed, somewhat shining, very finely punctate, with scarcely 
any pubescence, ferruginous or piceo-ferruginous, with the apex of the elytra blackish. 
Head broad, very finely punetate, smooth, with very slight impressions at the base of the 
epistome; eyes large. Thorax transverse, broader than long, slightly convex, even, very 
little narrower in front than behind, the sides slightly rounded, apex slightly emarginate 
and bisinuate, gently and slightly projecting in the middle, anterior angles rounded, pos-
