Atlantic States; abundant; feeds chiefly upon Clematis. The head of the 

 female is less dilated behind the eyes, and the antennae are much shorter. The 

 spurs of the posterior tibiae are as in the preceding species. 



I was at first inclined to retain for this species the name under which it is 

 usually known, though it is not properly the earliest. By the kindness of my 

 friend Prof. Lacordaire, I have received a transcript of the portion of Pallas' 

 work which relates to North American Coleoptera, and I there find that the 

 earlier name was in reality the one current among entomologists of that time. 

 I therefore must regard the substitution of Fabricius' later name as an accident, 

 arising from the wide circulation of his works, and the comparative scarcity of 

 Forster's small pamphlet. I do not understand how Fabricius, in his Syst. Ent. 

 emend., quotes Olivier, whose work bears date on the title page, 1 795, and whose 

 first volume of plates is dated 1808.

Mexican Boundary; collected by Mr. Clark, under Col. J. D. Graham. The 

 hody is a little more robust than in the preceding, black, finely and densely 

 punctured, covered with dense, yellowish brown hair. Head rounded behind, 

 not dilated behind the eyes ; antennae black, setaceous, joints not closely articu- 

 lated; labrum deeply emarginate. Thorax not narrower than the head, a little 

 wider than long, moderately convex, rounded in front, and finely channeled. 

 Elytra a little wider than the thorax, convex. Legs rufous, pubescent like the 

 hody, knees, tip of the tibiae and tarsi black. Spurs of the posterior tibiae slen- 

 der, subacute.

Missouri Territory ; tolerably abundant. The labrum is scarcely emarginate ; 

 the spurs of the posterior tibice are very slender and acute. The antennae of the 

 female are scarcely longer than the head and thorax, and are filiform ; the 2d 

 and 3d joints are rufous at base; the maxillary palpi of the male are strongly di- 

 lated and compressed. 



37. L. conspersa, atra, dense flavo-cinereo-pubescens, elytris punctis 

 paucis minutis denudatis conspersis, thorace convexiore, antennis elongatis.

Missouri Territory. This species is so similar to the preceding, that were it 

 not for the difference in the length of the antennae, they could only be considered 

 as varieties. The pubescence is slightly tinged with yellow, and is more coarse; 

 the thorax is a little more convex and more bell-shaped; the antennae in both 

 sexes are half as long as the body; the black spots are punctiform and much 

 less numerous. The male, as in the preceding species, has the palpi strongly di- 

 lated and compressed. 



38. L. v i 1 1 a t a, atra, punctulata subtilius pubescens, capite rufo, nigro bi- 

 maculato, thorace longiusculo flavo pubescente, nigro bivittato, elytris vix ru- 

 tosis luteis vittis duabus latis nigris. Long. -45 Q5.
