136 HETEROMERA. 
1. Trichoton lapidicola. 
Trichoton lapidicola, Haag in litt. 
Broad ovate, dull black, clothed with coarse light brown or ferruginous appressed scale-like hairs, and the upper 
surface also with scattered suberect short stout bristly hairs. Head rather coarsely but not very closely 
punctured ; prothorax irregularly, sparingly, and rather closely punctured (more closely towards the base), 
the anterior half of the disc smoother, somewhat densely clothed with scales towards the sides, the dise from 
base to apex more or less bare; elytra rounded at the sides, regularly and closely punctate-striate, the 
punctures coarse and transverse, the interstices smooth or feebly wrinkled, convex from the third outwardly 
(the third, fifth, and seventh more distinctly raised and broader), the pubescence arranged in scattered 
tufts ; anterior tibie in the male stout, gradually widening outwardly, inwardly curved from the middle, 
and obliquely truncated at the apex. 
Length 7-74 millim. (<¢.) 
Hab. Nicaragua, Granada (Sallé), Chontales (Belt)—Soutn America, Venezuela 
(coll. F. Bates). 
Single examples only from each locality. 
2. Trichoton curvipes. (Tab. VI. fig. 25, 2.) 
Narrower and more parallel in form than TZ. lapidicola, not so dull, slightly shining (when the scales are 
removed); the prothorax more closely punctured, the expanded lateral margins rather less concave 
(especially anteriorly) within ; the elytra longer and narrower and more parallel, the upper surface (in 
addition to the usual scale-like pubescence) more thickly clothed with suberect short ferruginous bristly 
hairs ; the anterior tibia in the male thin, slightly widening outwardly, abruptly twisted and inwardly 
curved before the apex, and the intermediate and posterior tibice in the same sex slightly widened, curved, 
and produced at their inner apices, before which very narrowly emarginate. 
Length 7-74 millim. (¢ @.) 
Hab. Panama, near the city (J. J. Walker). 
Three examples differing as above. 
CNEMEPLATIA. 
Cnemeplatia, Costa, Ann. degl. aspir. Nat. ser. 2, 1. p. 146 (1847) ; Horn, Rev. Ten. N. A. p. 360; 
Lec. & Horn, Class. Col. N. A. p. 380. 
Autocera, Wollaston, Cat. Col. Madeira, p. 154, t. 1. figg. 2, af; Lacord. Gen. Col. v. p. 280. 
Two or three species of this minute but interesting and widely distributed genus 
have been described from the Mediterranean region, one from Madeira, and one from 
California; we have to add yet another species from the State of Panama. An allied 
genus devoid of eyes (A/audes, Horn) is found in California. 
1. Cnemeplatia laticollis. (Tab. VI. fig. 24.) 
Elongate oval, subparallel, feebly convex, somewhat depressed above, pitchy or dark reddish brown, clothed 
with yellowish brown silky appressed scale-like pubescence. Head very broad, short, feebly emarginate in 
front, base almost truncate and extending (very narrowly) on each side as far as the small and not very pro- 
minent eyes, with a curved oblique impressed line (starting from the inner upper margin of the eyes, and 
extending forwards, but not reaching the middle) on each side, closely and finely punctured ; prothorax 
strongly transverse, the base and apex feebly bisinuate, the sides feebly rounded and slightly narrower at
