(^blong-Dval. Grayish or fusrous; wlu'ii clean often purplish. Clyp<nis 

 broadly rounded ; front with four small tufts of brownish hairs. Thorax 

 \\ ith sides feebly curved, gradually wider to base, the median groove shal- 

 low but entire, surface each side roughly punctured. Elytral tubercles 

 feebly elevated, widely distant; intervals with minutr tulicrcles or granules, 

 tliese subobsolete on the sides; intervals one (o three cacli with four slightly 

 elevated broken lines. Length 9-10.5 mm. 



Southern half of State; fro(|iiont. April 12-I)eceinher 25. 

 Clean specimens can be quickly recognized by the fine "capillary 

 lilies" on the intervals near the suture. Say's specific name was 

 ])aso(l on the presence of these lines.

 these with two rows of very short brown, scale-like hairs ; intervals each 

 with a row of minute brownish tufts of hair and two rows of large, trans- 

 verse, shallow punctures. Length 9.5-11.5 mm. 



Southern half of State ; frequent. May 2-June 10. Larger than 

 capUlarh, and readily distinguished by the carina-like lines of 

 elytral tubercles and the larger and more distinct rows of punctures.

 Oblong-oval, broader behind. Dull black. Clypeus broadly rounded. 



Thorax two-thirds wider than long, sides nearly straight, ciliate with very 

 short hairs; median groove slightly interrupted, its sides somewhat sinuous; 

 surface roughly punctured and witli a rounded impression each side on 

 basal half. Elytra each with four rows of tubercles, those on basal half 

 of first and second rows more elongate ; intervals each with a single row of 

 small distant tubercles. Front tibia> finely toothed above the median tooth. 

 Length G-S mm. 



Jennings, Putnam, Dubois and Posey counties; scarce. A])ril 

 24-May 12. This and the i-ciuaining five species are all small in 

 size and difficult to separate. Tliis is the largest of tlic six, more 

 robust and broader behind th(; middle. It resembles inherculalus in 

 form and sculpture, but is distinctly sinallci' and has the scales of 

 the tubercles much paler.
