slightly shorter than the fourth ; tarsal characters as in pimdulata, except 

 that the third joint of the intermediate tarsi is feebly lohed.

The unique specimen, which is fortunately a male, represents a 

 remarkably distinct species, not at all closely related to any other 

 here described, and readily known by its cuneate elytra, dull lustre 

 and peculiar pronotal punctuation. 



The anterior tibia? of the male are broadly, very obtusely toothed 

 internally at basal two-fifths, this character being common to the 

 males of a large number of species; in punctulata and oculatifrons 

 it is more nearly in the form of a broad swelling. 



L.. punctulata Melsh.— Proc. Ac. Phil., Ill, 1846, p. 59.— Elongate- 

 oval, dark castaneous ; under surface and legs piceous-black, the tarsi and 

 antenniB rufo-ferruginous ; surface strongly polished throughout, the pubes- 

 cence rather fine, somewhat long and sparse. Head rather strongly, sparsely 

 punctate ; eyes very large ; antennae slender, filiform. Prothorax one-half to 

 three-fourths wider than long, the sides distinctly convergent and nearly 

 straight from the basal angles nearly to the apex, then strongly rounded for 

 a short distance to the apex, which is truncate and three-fourths as wide as 

 the base, the latter transverse, the sinuations broad and deep; basal angles 

 right, not blunt ; disk obsoletely, broadly impressed along the middle, very 

 coarsely, nearly evenly and rather closely punctate, the punctures separated 

 by two to three times their width ; basal foveae distinct. Elytra four times as 

 long as the prothorax and scarcely perceptibly wider than the base of the 

 latter, gradually acute behind from the middle ; sides nearly straight thence 

 to the base ; disk rather finely but deeply striate, the punctures moderately 

 coarse and not very approximate ; intervals feebly convex, rather finely and 

 not very closely punctured. Abdomen somewhat strongly, sparsely punctate, 

 a little more closely so along the middle in the male. Legs long, slender, the 

 basal joint of the hind tarsi equal in length to the remainder. 



Male. — Narrower than the female ; eyes broadly rounded throughout inter- 

 nally and subcontiguous through an interval equal to one-half the length of 

 the epistoma ; antennae fully one-half as long as the body, with the third joint 

 two-thirds as long as the fourth ; anterior tarsi with the four basal joints 

 strongly lobed beneath, the intermediate with the fourth only, the posterior 

 with the penultimate narrowly and rudimentarily lobed. 



Female. — Eyes separated by fully one-half their own width ; antenufe two- 

 fifths as long as the body, the third joint but slightly shorter than the fourth ; 

 anterior tarsi with the three basal joints perfectly simple, the fourth strongly 

 lobed, intermediate and posterior nearly as in the male. 



Length % 9.0, J 9.3-9.7 mm.; width % 3.0, 5> 3.5-3.7 mm.
