BRACHIDA,.—BRACHYCHARA. 267 
Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
Antenne with elongate and slender basal joint; second joint slender, but broader 
and much longer than the slender third joint; fourth joint small; fifth to seventh 
each rather longer than broad, darker in colour than those preceding, the remainder 
broken off. Head only half as broad as the elytra. ‘Thorax very transverse, trans- 
versely convex ; base rounded and emarginate in the middle. Elytra longer than the 
thorax, covered with extremely fine granules. Lateral margins of hind body much 
elevated, and forming a sharp edge. 
Although the specimens are in such a decayed condition that only a superficial 
examination of them is possible, yet it is evident this is a very distinct species, but is 
connected with the ordinary forms of the genus by means of B. carinata. The antenne 
bend backwards at the slender extremity of the more than usually elongate basal joint, 
and thus assume a geniculate appearance. I do not detect any sexual distinctions. 
BRACHYCHARA. 
Corpus crassum, convexum, prothorace amplo, convexo, lateribus abruptissime inflexis. Prosternum brevis- 
simum. Coxe intermedia sat distantes; metasternum inter eas sat longe productum, cum mesosterno 
processu lato conjunctum. Metasternum breve; cox posteriores magne. Tarsi posteriores articulo 
basali elongato, ultimi fere squali. 
A peculiar form, indicating in several respects an. approach to the Tachyporini. The 
head is capable of great inflection ; and the segments of the- hind body are extremely. 
retractile. The head is short and broad, the parts of the mouth small, and apparently 
without much peculiarity. The thorax is very convex transversely, and the ample- 
sides are so abruptly inflexed that, viewed from beneath, they present a quite 
sharp edge; the prosternum is extremely short. The mesosternum is oblique in 
direction; and the middle coxe are rather widely separated; the metasternum is much 
produced between them, so that its process is as long as that of the mesosternum; and 
its margin is rounded in front and received in, or on, the mesosternal process, to which 
it is so accurately adapted that the outline of the two is indistinct ; the suture between 
them, viewed in a certain light, appears however somewhat thickened. The middle 
tarsi are rather short, four-jointed, the terminal joint as long as the three basal 
together. The five-jointed hind tarsi have the basal and apical joints elongate and 
subequal. 
At present the genus is, I think, best located near Brachida, to which, however, it is 
by no means closely allied.
