1. Mecomycter testaceipes, n. sp. 

 Listrus corallipes, Gorh., Biol. Centr.-Am., Coleopt. iii, 

 2, p. 127 (part.). 



Moderately elongate, the head and prothorax dull, the elytra 

 moderately shining; nigro-piceous, joints 1-6 of the antennae and 

 the legs rufo -testaceous; clothed with an extremely fine adpressed 

 pubescence (giving a pruinose appearance to the surface), the 

 marginal ciha wanting. Head about as long as broad, bi-impressed 

 in front, densely, finely punctate, the epistoma somewhat produced, 

 transverse; antennae short, much widened outwards, joints 3-6 

 slender, 7-10 strongly transverse, 7 and 8 equal, much wider than 

 6, 9 and 10 broader than 8, stout, II oblong-ovate, nearly as wide 

 as 10, longer than 9 and 10 united. Prothorax, narrow, transverse, 

 convex, laterally compressed, subcorneal, with a small angular 

 projection on each side towards the base, the marginal carina in- 

 ferior, the hind angles distinct ; densely, finely, uniformly punctate. 

 Elytra, very much wider than the prothorax, oblong, rather de- 

 pressed, subparallel at the base, less than twice as long as wide, 

 incompletely covering the abdomen, with prominent tumid humeri ; 

 rather sparsely, minutely punctate and transversely rugulose. 

 Legs slender ; tibiae with a few extremely minute spinules on their 

 outer edge; fifth tarsal joint cylindrical, the claws extremely 

 slender, simple. 



Length 2|, breadth 1^ mm. 



Hab. Mexico, Toxpam (Salle). 



One specimen, probably a male, differing from M.facetus, 

 Casey, to judge from the description, in having the pro- 

 thorax and elytra much more finely punctured, the body 

 uniformly piceous, the vestiture very fine and wholly 

 decumbent, etc. 



Subfam. MELYRINAE. 



Melyeodes. 



Melyrodes, Gorh., Biol. Centr.-Am., Coleopt. iii, 2, pp. 128 



(1882), 331 (1886). 

 Alymeris, Casey, Ann. N. York Acad. Sci. viii, p. 600 (1895). 



A genus including a few species from North and Central 

 America, two being now added from the last-named region. 

 The synonymy has already been noted by Casey (op. cit. 

 ix, p. 682).
