AMERICAN COLEOPTERA. 313 



C. pnbernlas Lee. — Globose-oval, piceous to piceo-testaceous, elytra paler 

 toward the tip. Head and thorax very sparsely minutely punctulate and 

 finely pubescent. Elytra more distinctly punctulate, very sparsely on the 

 disc, gradually more dense to the tip, surface sparsely pubescent. Body beneath 

 sparsely minutely punctulate and pubescent. Legs and antennsB testaceous. 

 Length .04 inch; 1 mm. 



Usually a little smaller than the preceding and differing in its 

 punctuation and pubescence. 



Occurs from Massachusetts to District of Columbia. 



C TulneratiiS Lee. — Globose-oval, piceous-blaek, each elytron with an 

 indistinctly limited rufous space at middle. Head and thorax extremely finely 

 and very sparsely punctulate and pubescent. Elytra with the humeral angles 

 rectangular, surface smooth on the <lisc, very sparsely punctulate at the sides and 

 near the apex and sparsely pubescent. Body beneath very minutely punctulate 

 and sparsely pubescent. Legs and antennae testaceous. Length .04 inch ; 1 mm. 

 Easily known by the above characters. The elytral spot is probably 

 not constant, and it is possible that other specimens will show that the 

 elytra may become gradually paler to tip as in puherulus. 

 One specimen, Garland, Colorado. 



C. seminnliim n. sp.— Closely resembling puberulus in form and color and 

 differs only in having the punctuation as in vulneratus. The humeral angles of 

 the elytra are rounded as in puberulus. Length .04 inch ; 1 mm. 



Two specimens, Camp Grant, Arizona. 



CAI.YPTOMERUS Redt. 



Characters of C/am6M5 with the following exceptions: Maxillary palpi with 

 the first joint.small, second much stouter, obconical, third much smaller, fourth 

 more slender and nearly equal to the two preceding, obtuse at tip. Antennae 

 ten-jointed, first joint short and stout, second somewhat globose, as stout as the 

 first, third slender, 4 — 6 slender, gradually decreasing in length, 7 — 8 small, 

 nodose, 9 — 10 forming an oval mass the terminal a little smaller; antennse 

 arising at a distance in front of the eye in a notch in the side of the front, the 

 antennee in repose received in broad shallow cavities on the under side of the 

 head between the eyes and the gula. Abdomen with six distinct segments. 

 Elytra slightly prolonged, subtruncate at tip. Body winged. Metasternum 

 very little excavated in front. The eyes are coarsely granulated above and 

 beneath and the tarsi are longer than those of Clanibus. 



The differences between this genus and the preceding are many and 

 important, and it seems rather remarkable that the insertion of the 

 antennae at a point so distant from the eyes should have escaped notice 

 in print, as that accurate artist Mr. Jules Migneaux has not failed to 

 represent it in his figure, (Duval, vol. i, pi. 18, fig. 189). 



C. oblongnlns Mann. — Oblong-oval, convex, contractile, piceo-testaceous, 

 moderately shining, sparsely pubescent. Head large, rapidly narrowing behind 

 the eyes, occiput vaguely transversely impressed, surface sparsely minutely 

 punctulate. Thorax smaller than the head but a little wider, more than twice
