NORTH AMERICAN COLKOPTEItA. 57 



episternum comes very far from attaining the metasternum in cereum 

 it actually borders it for a short distance in the present species. 



T. pillictatum n. sp. — Form nearly as in cereum; glabrous ; shining. 

 Head small ; rostrum very short, robust, strongly constricted at the base 

 between the eyes, enlarged at the tip, which is transversely truncate and 

 clothed at the sides with very sparse setae ; surface rather finely rugulose ; 

 front finely punctate in the middle, more coarsely so toward the eyes, 

 minutely granulose, rather strongly convex ; eyes coarsely granulate. Pro- 

 thorax slightly longer than wide, widest at the base whicli is broadly angii- 

 late, angle broadly rounded ; apex nearly one-half shorter, strongly arcuate ; 

 sides gradually divergent posteriorly except in the middle, where they are 

 abruptly arcuate for a short distance, very feebly sinuate just before the 

 basal and behind the apical angles ; angles at base and apex rather promi- 

 nent ; disk very sparsely and minutely punctulate toward the base, with a 

 very few widely scattered larger punctures ; surface polished in the apical 

 half, granulose toward the base ; just behind the apical margin there is a 

 transvei'se row of small punctures, which become very large and deep on the 

 flanks. Elytra widest at the humeri, where they are one-third wider than 

 the pronotum at base ; sides thence feebly convergent posteriorly and acutely 

 roiinded behind ; disk very convex, polished, reticulated ; very strongly, 

 coarsely, and sparsely punctate, punctures arranged in rows ; suture nearly 

 two and one-half times as long as the pronotum. Scutellum minute, longer 

 than wide. Legs robust ; last joint of the tarsi slender ; claws very small, 

 strongly arcuate. Last ventral segment as long as the two preceding together, 

 nearly flat, very strongly arcuate behind ; surface sparsely and somewhat 

 finely punctate. Color of the upper surface of the body brassy-bronze, that 

 of the lower surface black, legs piceous. Mesosternal episternum not attain- 

 ing the metasternum. Length 4.0 mm. ; breadth 1.8 mm. 



Willets Point, Long Island. 



From cereum this species differs radically in its much larger size, 

 in the shape of the prothorax and elytra, in the punctuation of the 

 latter, in the punctuation of the under surface, especially of the meta- 

 sternum and last ventral segment, and in the punctuation of the 

 pronotum. In cereum the punctures of the elytra are smaller, and 

 generally joined in the rows by at least a feeble impressed channel, 

 giving sometimes the appearance of a punctate stria, and the sculpture 

 of the last ventral segment is very close, coarse, coalescent, and con- 

 fused, more particularly so toward the tip. The greatest difference 

 exists, however, in the shape of the pronotum, the sides being abruptly 

 constricted at the base in cereum, so that it is widest before the middle ; 

 that species also lacks the row of punctures behind the anterior mar- 

 gin. The metasternum in cereum is very coarsely and deeply punctate 

 while in the present species it is sparsely and rather finely so. 



The type specimen was found clinging to the under surface of a 

 stone on the shore of a small pond.
