One specimen, Pennsylvania; Mr. Rathvon. Closely resembles the preceding, 

 and might readily be taken for a variety of it ; but the antennae are entirely 

 black, the postpectus and tip of the femora are also black; the limits between 

 the red and black of the plytra are badly defined; and the punctures of the under 

 surface are very much finer.

Middle, Southern an*d Western States. Latreille was the first to apply to this 

 species the description of Fabricius, with which it by no means agrees ; the 

 other authors above mentioned have merely copied the error from him. 



1 should have applied the name given by Newman to this species, were it not 

 that the size mentioned in his description (long. *6 unc. ; lat. '03 unc.) could 

 never be attained by it. The relative proportions of the length to the breadth 

 are., however, impossible in this genus, and in other respects the description 

 agrees with the species here described.

One specimen, Georgia: resembles in appearance L. puncticollis, but is longer 

 and narrower. Body rufous ; head finely punctulate. Antennae shorter than the 

 head and thorax, black, with the second to the sixth joints slender, subequal ; 

 the 7th is slightly dilated, but not more than half as wide as the 8th, which 

 again is narrower than the 9th; 9th and 10th equal, slightly transverse ; 11th 

 rounded. Thorax nearly one half longer than wide, widest about the middle, 

 broadly rounded on the sides, convex, finely, not densely punctulate, with a dis- 

 coidal oval black spot reaching from the apex to behind the middle. Elytra not 

 wider than the thorax, bluish black, with fine rows of punctures becoming obso- 

 lete at the tip. Beneath rufous, first and second segments of the abdomen 

 sparsely, coarsely punctured ; fourth and fifth segments black. Legs black, basal 

 half of the femora rufous. 



9. L. teed a t a, piceo-rufa, nitida, capite postice nigricante, thorace latitudine 

 fere sesqui longiore antrorsum angustato, lateribus rotundato, parce punctata, 

 macula dorsali indeterminate nigra, elytris aeneo-r.igris, subtiliter striata -punc- 

 tatis, antennis nigris. pedibus fusco-rufis, femoribus acnescentibus. Long. -41. 



One specimen found on the sea shore near New York. Body moderately slen- 

 der, dark rufous tinged with piceous and brassy; head sparsely punctured, punc- 

 tures finer towards the occiput, which is nearly black. Antennae shorter than 

 the head and thorax, joints 2 6 slender, the third being twice as long as the 

 second; 7th slightly dilated, 8th still more dilated, but not as wide as the 9th 

 and 10th, which are somewhat transverse; 11th larger, rounded. Thorax nar- 

 rowed at the base, more narrowed anteriorly; sides broadly rounded ; disc mo- 

 derately convex, sparsely, not finely punctured, with a large rounded, ill-defined, 

 dorsal spot. Elytra brassy black, shining, finely striato-punctate, striae finer 

 posteriorly, but extending almost to the tip. Under surface entirely rufous with 

 a piceous tinge, uniformly sparsely punctured. Legs fusco-aeneous, femora, ex- 

 cept at base, piceous black tinged with brassy; tarsi almost rufous.
