This species and L. suturalis, though of broad form, are distinguished from their 
allies by the narrower and more pointed process separating the hind coxe ; this 
character, combined with the deep coarse thoracic stria, should enable them to be 
easily recognized. The thorax is a little undulating at the sides, and there is a distinct 
denticle behind the middle. The three elytral strie are widely separated, and the 
intra-marginal costa is quite distinct ; the sides external to this costa are perpendicular ; 
the epipleure are broad and horizontal. The under surface is polished and shining, 
only sparingly and obsoletely punctate. The punctuation both of the upper and under 
surfaces is variable, and is sometimes almost entirely obsolete. Thirty-two specimens. 
L. distinguendus is no doubt allied to the Texan L. terminalis, Casey, as well as to 
the European L. denticulatus, Preyssl.

Deplanatus, levigatus, capite prothoraceque parce punctatis ; rufo-testaceus, circa scutellum nigricans; antennis 
minus gracilibus, articulis tribus ultimis evidenter paullo latioribus ; prothorace valde transverso, utrinque 
profunde unistriato ; elytro singulo evidenter tristriato, exterius costato-marginato.

anterius leviter emarginato.

Elytris margine exteriore nigricante. Maris linea epistomatica obsoleta, a labro latius separata. 
Hab. Mexico, Jalapa (Hoge). 
This species is very closely allied to LZ. distinguendus: though the males of the two 
are readily distinguished, I am unable to point out any characters that will distinguish 
the females without actual comparison. JL. suturalis, 2? , has a longer after-body, a more 
distinctly punctured head and thorax, and the thorax is a little less rounded at the sides. 
The difficulty of determining this species is increased by the fact that the male 
characters become so much diminished that in some specimens scarcely any external 
distinction remains as regards the head and antenne ; the sexes are, however, readily 
distinguished by the number of joints in the hind feet.
