various Central American Coleoptera. 17 
compact 3-jointed club, and the 4-jointed, simple tarsi. 
The genus can be placed for the present in Colydiidae, 
near the Cerylinae. TJ. rufus has been found in Ceiba 
(Bombaz) bark in Cuba.

the legs and palpi testaceous. Head sparsely, finely punctate ; 
antennae not reaching the middle of the thorax, joints 1 and 2 stout, 
2 transverse, 3-6 gradually widening outwards, 3 about as long as 
broad, 4-6 transverse, the club as long as 3-6 united, 8 strongly 
transverse, 9 blunt at the tip. Thorax short, transversely convex, 
rounded at the sides, the latter sinuate before the base, the hind 
angles acute; the surface sparsely, finely punctured, and with 
several coarser impressions on each side near the base. Scutellum 
transverse, flat. Elytra moderately long, somewhat flattened on 
the disc, of the same width as the thorax, parallel in their basal 
half, the humeri angular; with rows of scattered punctures, which 
become almost obsolete towards the apex, the interstices broad, 
flat, smooth. Beneath very sparsely, finely punctate; fifth ventral

Hab. Guatemata, San Gerédnimo, El Jicaro, Tamahu 
(Champion) ; CuBa, Cayamas (Schwarz, in U.S. Nat. Mus.).

others were found by Mr. Schwarz in Cuba. 
*Tyrtaeus cribripennis, 0. sp. 
Smaller and less elongate than 7’. rufus, obscure ferruginous, the 
antennal club infuscate. Antennae with the intermediate joints a 
little shorter, the club nearly as long as the rest of the joints united. 
Thorax very sparsely, finely punctate, with some coarse punctures 
along the basal margin. Scutellum triangular. Elytra shorter than

antennae is so closely articulated to the club that it is not 
easily seen.
