AMERICAN COLEOPTERA. 21 



dense!}' in the usual position of the oblique impression. Elytra as wide as the 

 thorax at base, suboylindrioal. gradually narrowed to tip and finely serrulate; 

 disc with strife of moderate punctures not closely placed, intervals flat, uniseri- 

 ately punctulate; surface rather irregularly maculate with yellow without any 

 distinct pattern. Body beneath dark bronze, sparsely pubescent. Prosternum 

 as in pu/chella. Abdomen sparsely punctured, last ventral with very distinct 

 submarginal carina. Length .26 inch ; 6.5 mm. 



This species is of the size form and general aspect of cn/fa but 

 may- be known by the surhice having the usual hairs and not setae 

 and by the last ventral having a distinct subapical carina. 



Two specimens Texas. 



A. versuta, n. sp.— (PI. I, fig. 3.3.) Form cylindrical, slightly depressed, 

 very little narrower at tip than in front, piceous slightly bronzed, sparsely 

 clothed with erect brownish hairs. Head densely punctate, front feebly im- 

 pressed, vertex not carinate. Thorax unicolored. nearly twice as wide as long, 

 apex slightly narrower than base, slightly prolonged at middle over the head, 

 sides rather strongly arcuate and slightly sinuate in front of base, margin very 

 narrow not visible from above; disc convex, a very slight depression at middle 

 of base, on each side a more distinct depression ; surface sparsely punctured at 

 middle, verv densely at the sides. Elytra as wide as thorax, sides parallel, at 

 aj)ical third arcuately narrowing and finely serrate ; disc moderately conve.^, 

 striate, < uter striae deeply impressed, punctured rather distantly, intervals flat, 

 uniseriately punctulate; surface with yellow spots arranged in a discal row of 

 fine equally distant, a marginal series of five or six irregularly placed. Sur- 

 face beneath bronzed sparsely hairy. Abdomen with the first three segments 

 sparsely punctured, last two more densely, last ventral with distinct double 

 margin at tip. Length .26 inch; 6.5 mm. 



Supertifially this species greatly resembles gnttlfera but the ab- 

 dominal characters abundantly distinguish it. The last two ventral 

 segments are in the pre.seut species mo|^ densely punctured than 

 those which precede, the punctures of the fifth segment are coarse, 

 those of the fourth unequal, the punctures neatest the base of the 

 segment are finer and denser than those at the tip. 

 One specimen Mariposa, California. 



A. guttifera, Lee— (PI. I. fig. 34.) Form cylindrical subdepressed, sur- 

 face piceous, faintly bronzed, sparsely clothed with brownish hairs. Elytra 

 witb three dorsal spots the first median the other two posterior, a marginal 

 series of five unequally placed. Body beneath bronzed. Ventral segments 

 unequally punctured, the first two very sparsely at middle and somewhat 

 more densely at the sides, the secon.l at sides rather more densely pubes- 

 cent; last three segments subopaque, very densely and very finely punctured 

 and clothed with moderately long fine, silken, erect hair which curves toward 

 the front; fifth ventral without any trace of subapical cariua. Length .28 

 inch ; 7 in m. 



Of this species I have seen I'Ut one specimen from Fort Tejon, Cali- 

 fornia, which is so abundantly distinct by its abdominal characters as
