BRYAXIS.—PSELAPTUS. 33 
the club should be called uni-articulate or three-jointed ; the head is differently formed, 
the thorax shorter, and the elytra exhibit a slight sculpture. It is unique. 
21. Bryaxis edipus. 
Rufo-castanea, elytris sanguineis, omnino minutissime pubescens, sat nitida; antennis brevibus, clava magna ; 
capite anterius impresso, utrinque inter oculos minute foveolato, vertice subconvexo ; prothorace brevi; 
elytris stria suturali subtiliter impressis, intra humeros obsoletissime depressis ; abdominis segmento basali 
quam secundum duplo longiore; tarsis anterioribus (? maris) articulo basali crassiore. 
Long. vix 13 millim. 
Hab. Guatemata (Sallé). 
Antenne with joints 3-8 small, the ninth and tenth joints also small, but transverse, 
the terminal joint very large, acuminate. Head transversely depressed in front, the 
clypeus being angulate in the middle and depressed; on each side near the eye is an 
obscure fovea, which is only indistinctly separated from the frontal depression. Thorax 
short and broad, much narrowed behind, without fovee, the base slightly transversely 
depressed. Elytra with only a fine sutural stria, and a very feeble impression at the 
shoulder. 
This insect also is unique ; it is allied to B. impudis, though abundantly distinct. The 
example is probably a male, the metasternum being broadly impressed, and it is very 
probable that the peculiar swelling of the front tarsus may be peculiar to this sex. 
PSELAPTUS. 
Pselaptus, Leconte, Tr. Am. Ent. Soc. viii. p. 184 (1880). 
This genus was established for a Texan insect, and distinguished from Bryawis by the 
absence of strize from the elytra. The single species from our region agrees with 
Pselaptus in this respect, but whether it be really congeneric with P. belfragei, Lec., 
must remain doubtful at present. 
1. Pselaptus batrisoides. (Tab. I. fig 17.) 
Convexa, laevigata, polita, rufa, elytris dilute sanguineis; antennis gracilibus, clava valde elongata; capite 
anterius subimpresso, utrinque inter oculos foveola minuta; prothorace inimpresso; abdominis segmento 
basali quam secundum vix duplo longiore. 
Long. vix 14 millim. 
Hab. Guatemaa, El Reposo (Champion). 
Antenne rather slender, joints 3-8 small, the ninth joint slightly broader, as long as 
wide, the tenth joint a little larger but similar, the terminal joint very long. Head 
rather broad and short, rather vaguely impressed in front, and with a small obscure 
fovea on each side. Thorax nearly as long as broad, smooth, and shining. Elytra 
convex, polished, without fovez or strie. Legs elongate. 
Unique.
