AMERICAN COLEOPTERA. 299 



Male. — Anterior tarsi slightly dilated. Posterior femora with a small denticle 

 at middle of lower edge. 

 Female. — Tarsi slender. Femur simple. 



Closely resembles Blanchardi and diflfers only in the confused strise 

 and punctulate intervals. 



Occurs from New Hampshire and Canada to Virginia. 



Li. basalis Lee. — Broadly oval, convex, shining, piceous-black, elytra 

 either entirely orange-red or with a humeral space of variable size of that 

 color. Head and thorax minutely sparsely punctulate. Elytra distinctly 

 sinuate on the sides when viewed laterally, surface with eight entire strise 

 of rather coarse much confused punctures, the ninth stria distant from the 

 margin at base becoming much confused and joining the margin at middle, 

 intervals scarcely visibly punctulate, the alternate with distant coarser punc- 

 tures. Body beneath sparsely punctate. Length .10 inch ; 2.5 mm. 



Male. — Anterior and middle tarsi dilated moderately. The posterior femur 

 flat beneath without tubercle or tooth. 

 Female. — Tarsi slender. 



As already noted this species varies in the color of the elytra, 

 usually there is a narrow basal red space extending from the humeri 

 to near the suture while in others the elytra may become entirely red. 

 These latter are the dichroa Lee. It is possible that black varieties 

 of this species may occur which will then closely resemble discolor 

 except in the irregularity of the elytral strise. Excepting in color it 

 also resembles obsofeta, but the punctures of the striae are here coarser 

 and the finer punctures of the intervals barely visible. 



Occurs from the Middle States north and as far west as Illinois. 



li. geminata n.sp. (Blanchard mss.) — Broadly oval, very convex, slightly 

 narrower behind, piceous-black, shining. Head sparsely minutely punctulate. 

 Thorax smooth, hind angles rectangular. Elytra distinctly sinuate on the sides 

 when viewed laterally, surface with eight rows of very much confused punc- 

 tures becoming almost double series, the ninth very short, and uniting with 

 the margin very close to the humeri, intervals very minutely punctulate. 

 Body beneath distinctly alutaceous, sparsely punctate. Length .12^— .14 inch • 

 3—3.5 mm. (PI. VII, fig. 7). 



Male. — Anterior and middle tarsi distinctly dilated. Posterior femur chan- 

 neled beneath but without tooth or tubercle. 



I have seen but two males of this species which approach in size 

 glohosa and polita but have a form more nearly resembling Tritoma 

 {Cyrtotriplax Cr.). The characters in the table are sufficient to 

 distinguish it from any at present known. 



Occurs from Massachusetts to Virginia and Illinois. 



1.. ConAtsa n. sp.— Broadly oval, not very convex, piceous-black, humeri 

 reddish, shining. Head very sparsely punctulate. Thorax scarcely perceptibly 

 punctulate. Elytra with the sutural stria moderately deeply impressed, the
