Atlantic States; abundant; feeds chiefly upon Clematis. The head of the 
female is less dilated behind the eyes, and the antenne are much shorter. The 
spurs of the posterior tibie 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 transeript 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, 1795, and whose 
first volume of plates is dated 1808. 
35. L. nigritarsis, atra, dense fusco-pubescens, thorace subtransverso,

Mexican Boundary; collected by Mr. Clark, under Col. J. D. Graham. The 
body 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 ; antenne black, setaceous, joints not closely articu- 
Jated; 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 
body, knees, tip of the tibiz and tarsi black. Spurs of the posterior tibie slen- 
der, subacute. 
36. L. maculata, atra, dense cinereo-pubescens, elytris guttis rotundatis 
denudatis spe confluentibus conspersis, thorace subquadrato, antennis brevi- 
usculis. Long. -27—-5.

Missouri Territory ; tolerably abundant. The labrum is scarcely emarginate ; 
the spurs of the posterior tibia are very slender and acute. The antenne 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- 
jated 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 antennz, 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 antenna in both 
sexes are half as long as the body: the black spots are punctiform and much 
less numerotis. The male, as inthe preceding species, has the palpi strongly di- 
lated and compressed. 
38. L. vittata, atra, punctulata subtilius pubescens, capite rufo, nigro bi- 
maculato, thorace longiusculo flavo pubescente, nigro bivittato, elytris vix ru- 
<osis luteis vittis duabus latis nigris. Long. -45—:65.
