being bisinuate anteriorly. It does not appear to be very 

 closely allied to any of the Central American genera, and 

 may be easily recognized by its short robust form, rather 

 large truncate head, simple sinuate labrum, slender fusi- 

 form third maxillary palpal joint, short antennc\3 and non- 

 carinate prosternum. I have compared it directly with 

 31edon hrimneus Erichs. 

 We have but one species. 



L. testacea n. sp.— Robust; sides parallel; pale rufo-testaceous, elytra, 

 legs, palpi and aatennre toward apex slightly paler aud more flavate; pubes- 

 cence of elytra and abdomen fine, rather long, not dense. Head about as 

 long as wide; sides parallel, almost straight; base transversely truncate, 

 feebly sinuate in the middle third; angles right, very narrowly rounded; eyes 

 at twice their length from the base, slightly prominent; front finely subgranu- 

 lose, coarsely, very feebly and not densely punctate, with a rather broad 

 median impunctate line; antennte equal in length to the head, distinctly in- 

 crassate toward tip; basal joint distinctly longer than the next two together, 

 second distinctly longer and more rob ist than the third, the latter slightly 

 longer than wide, joints four to ten subequal in length, increasing distinctly 

 in width, the former as long as wide, the latter much wider than long. Pro- 

 thorax widest at the anterior angles, slightly s'lorter and narrower than the 

 head, very slightly wider than long; sides rather feebly convergent from apex 

 to base, very feebly arcuate; base broadly subtruncate; angles rather broadly 

 rounded; anterior angles rather more narrowly rounded; sides of apex very 

 strongly convergent to the neck, nearly straight; nuchal truncation rather 

 feebly sinuate, two-fifths as wide as the disk; the latter feebly and 

 evenly convex, finely subgranulose, rather coarsely, evenly and feebly punc- 

 tate; punctures denser aud finer than those of the head, with scarcely a trace 

 of a median impunctate line. Elytra at base very slightly wider than the 

 prothorax, as wide as the head; sides very feebly divergent, nearly ^straight; 

 together broadly and extremely feebly emarginate behind; disk as long as 

 wide, one-third longer than the prothorax, very feebly convex, scarcely im- 

 pressed along the suture, which is bordered with a thickened but scarcely 

 elevated margin; surface not granulose, polished, rather finely, evenly and 

 not densely punctate, punctures impressed, deeper but not as large as those 

 of the pronotum. Abdomen very slightly narrower than the elytra; sides 

 parallel and distinctly arcuate; border rather narrow, deep and strongly in- 

 clined; surface broadly convex, very finely and feebly reticulate, polished, 

 excessively minutely aud rather sparsely punctate, each puncture being en- 

 tirely fiUeJ by a hair. Le/js rather short and very slender. L3ngth 2.2 mm.
