wide, barely a fifth wider than the prothorax, alutaceous in both 

 sexes though more strongly in the female; surface (9) punctured 

 laterally and basally as in longicollis, the fine punctures of the outer 

 two intervals very feeble, or (cf) with the punctures more minute 

 and very sparsely scattered on the basal parts of the fifth, to nearly 

 throughout the seventh, interval", the minute punctules of the outer 

 two intervals extremely few in number and subobsolete; hind tarsi 

 with very few fine hairs above. Length (cf 9 ) 10.5-13.0 mm.; 

 width 4.0-5.0 mm. Rhode Island and New York (Plattsburg). Six 

 examples dolosus n. sp. 



II Form parallel, the prothorax about as wide as the elytra 12 



Form more oblong-oval, the prothorax always visibly, though never 

 greatly, narrower than the elytra 13 



12 Size moderate, not very convex, shining, the elytra only feebly alu- 

 taceous in the female, blackish-castaneous in color, the under surface 

 more rufous, the legs pale testaceous; head well developed, three- 

 fifths as wide as the prothorax, the eyes moderately prominent, the 

 antennae slender, moderate in length; prothorax a fourth to third 

 wider than long, nearly quadrate, the parallel sides very feebly 

 rounded, more converging anteriorly, the apex distinctly narrower 

 than the base, which is transverse, margined throughout, with the 

 angles right and narrowly rounded; surface feebly convex, rather 

 widely reflexed at the sides, the gutter strongly punctate, gradually 

 slightly widening and merging in the general flattening near basal 

 fourth; basal parts strongly punctured throughout the width, more 

 finely medially, coarsely in the large vague foveae and more sparsely 

 near the sides; elytra oblong, parallel, with very feebly arcuate sides, 

 not three-fifths longer than wide, the sinus feeble, the striae coarse 

 and deep, extremely finely punctulate along the bottom, the scutellar 

 long, coarse and free; intervals (-cf ) flat or nearly so and impunctate, 

 or ( 9 ) with the fifth and seventh usually having very widely spaced 

 subserial puncture and the two outer intervals very minutely, sparsely 

 punctulate, the foveae of the lateral line strong, uninterrupted; hind 

 tarsi almost completely glabrous above. Length (cf 9 ) 10.5-13.5 

 mm.; width 3.3-5.0 mm. Rhode Island to Missouri. Common.

Size much larger, rather depressed, blackish-piceous in color, rufescent 

 beneath, the legs pale flavo-testaceous, shining, the elytra (cf) very 

 feebly alutaceous; head not quite three-fifths as wide as the prothorax, 

 the foveae minute, linear, lying in large impressions; eyes rather large, 

 moderately prominent; antennaa unusually long, slender, extending 

 well behind the thoracic base; prothorax less than a third wider than 

 long, widest well before the middle, the sides broadly rounded, feebly 

 converging and less arcuate thence to the very obtuse and narrowly 

 rounded angles, the base transverse, somewhat wider than the apex, 

 feebly arcuate near each side, margined; surface depressed, with 

 strong median stria from the feeble anterior impression to the base; 

 sides coarsely reflexed and punctate, the gutter but slightly wider 

 posteriorly and losing itself in the flattened hind angles; foveae large, 

 very densely and rugosely punctured and rather deep; elytra nearly
