Coleopterological Notices, IV. 453 



clouded spot at the middle nearer the side than the suture, and an- 

 other smaller and rounded at apical fourth ; surface feebly shining, 

 the vestiture very sparse, consisting of short robust recumbent 

 hairs, yellowish in color and especially evident on the elytra near 

 the base, in an oblique band just before the middle, and another at 

 apical third not attaining the suture. Head and beak closely and 

 deeply punctate, the former with a small depressed cluster of hairs 

 at the middle of the vertex, separated from the beak by a broad 

 transverse impression which is obsoletely foveate at the middle. 

 Prothorax very nearly as long as wide, broadly rounded at the sides, 

 narrowed and with the sides broadly, just visibly sinuate toward 

 apex, the latter strongly arcuate ; disk very coarsely deeply evenly 

 and densely punctured throughout. Elytra at base not wider than 

 the disk of the prothorax, three-fourths longer, widest at basal third 

 where they are two-fifths wider than the prothorax, minutely punc- 

 tulate throughout, more obsoletely in the black spots, and with ob- 

 soletely impressed series of very distant punctures, becoming coarse 

 toward base and minute toward apex. Length 4.0-4.2 mm. ; width 

 1.8-1.9 mm. 



Illinois and Missouri. One of the most distinct species of our 

 fauna, perhaps most closely allied to variegata, but radically differ- 

 ent in its shorter oval and confusedly punctulate elytra, with the 

 humeri scarcely at all exposed at base, and in its very dense cribrate 

 punctures of the prothorax. 



6 T. variegata Horn— Proc. Am. Phil. Soc, XIII, p. 468 (Analois). 



Oval, strongly convex, rather shining, in great part glabrous, 

 black, the pronotum feebly rufescent near the apex and the elytra 

 with small widely scattered rufous patches, of which a narrow 

 oblique subsutural spot just before the middle and a wide, broadly 

 and posteriorly arcuate band at apical third or fourth, are particu- 

 larly noticeable, the rufous areas clothed rather sparsely with fine 

 recumbent }^ellowish-white squamules, the black portions glabrous. 

 Head and beak very densely, rather finely punctate and dull through- 

 out, with a small impressed frontal fovea ; beak in the female nearly 

 twice as long as wide. Prothorax slightly longer than wide, the 

 apex narrower than the base and strongly, evenly arcuate ; punc- 

 tures large, deep, unevenly distributed but rather close, fine toward 

 apex. Elytra at base one-third wider than the prothorax, fully 

 twice as long, the sides parallel and nearly straight in basal three-
