PROMECOPS. 315 
tarsi (fig. 25) with a stout dentiform process on the upper surface of the inner portion of the bilobed 
third joint in ¢ ; tarsal claws free. 
Length 44-54, breadth 12-21 millim. (¢ 9.) 
Hab. Panama, Caldera and David in Chiriqui (Champion). 
Two males and two females, the single example from David being a very large 
female with the rostrum concave above. The toothed inner lobe of the third joint 
of the anterior tarsi of the male is a remarkable character. The female is very like 
that of P. wnidentata, from which it may be known by its shorter antenne, the 
broader rostrum, the less convex, more finely punctured prothorax, which is as wide 
at the apex as at the base, the suberect long elytral sete, and the non-protuberant 
mesosternum. 
6. Promecops tridentata, sp. n. (Tab. XIV. figg. 26, 26a, ¢.) 
Oblong, robust, piceous ; variegated with a dense clothing of cinereous, brown, and blackish scales, the 
cinereous scales condensed into a curved stripe on each side of the prothorax, a spot on the scutellum, 
and two curved transverse fascize on each elytron (one, before the middle, sometimes interrupted, not 
reaching the suture, widening outwards, and connected exteriorly with a transverse humeral patch, the 
other subapical) ; the elytra also set with long, suberect, rigid setee down each interstice, and the rest of 
the upper surface with short, curled, decumbent, bristly hairs; the legs annulate, the scales on the under 
surface of the body uniformly cinereous. Rostrum broad, depressed, and canaliculate down the middle; 
joints 1 and 2 of the funiculus subequal in length. Prothorax strongly transverse, rounded at 
the sides, slightly constricted in front, finely carinate or obsoletely canaliculate down the middle from 
near the apex to the base, the surface finely, closely punctate. LElytra oblong-subtriangular in <, 
subparallel in their basal half in 9, punctate-striate, the interstices feebly convex. Mesosternum 
simple. Legs stout; all the tibia strongly unguiculate, the anterior pair in ¢ (fig. 26a) armed on 
the inner edge with three long, projecting, truncated or slightly hooked teeth, and usually with a 
smaller additional tooth near the tip, in 2 with three small teeth only; tarsal claws free. 
Length 32-6, breadth 14-23 millim. (d 9.) 
Hab. Guatemata (Mus. Brit.), Capetillo, Zapote (Champion). 
Numerous examples, the sexes about equal in number. The three long, projecting, 
more or less hooked teeth on the anterior tibiee of the male characterize this species, 
a female of which was acquired by the British Museum in 1855. 
7. Promecops clavisetis, sp.n. (Tab. XIV. figg. 27, 274, 2.) 
Oblong, convex, robust, piceous; variegated with a dense clothing of blackish, brown, and cinereous scales, 
the darker scales on the elytra condensed into a broad post-median fascia, and the cinereous scales into 
an irregular fascia below the base and a narrower and straighter one towards the apex ; the alternate 
elytral interstices also set with scattered, stout, clubbed, setiform, light and dark scales, and the rest 
of the surface with short, curled, decumbent sete. Rostrum broad, canaliculate; joint 2 of the 
funiculus longer than 1, Prothorax convex, transverse, rounded at the sides, closely punctate. Elytra 
subparallel in their basal half, somewhat gibbous, transversely depressed below the base; punctate- 
striate, the alternate interstices raised, the others feebly convex. Mesosternum not protuberant. Legs 
very stout; the tibiz feebly unguiculate; tarsal claws free. 
Length 5}, breadth 24 millim. (@ ?) 
Hab. Mexico, Toxpam in Vera Cruz (Sad/é). 
One example, somewhat injured by pinning. A robust, convex form, with somewhat
