TALANUS. 323 
Hab. Guatemata, Las Mercedes, Cerro Zunil (Champion). 
Four female examples. This insect is distinguished from its allies by the fine and 
very lightly impressed elytral punctures, the punctures being shallower and finer than 
in any other species of the genus known to me. 
3. Talanus subopacus. 
Elongate, subcylindrical, brownish-piceous or dark reddish-brown, rather dull. Head rather closely and finely 
punctured, deeply transversely impressed in front; antenne as in 7’. neotropicalis ; prothorax coarsely and 
very irregularly punctured, the sides broadly behind the middle (in one example with large smooth spaces) 
and the base very much more sparingly so, the sides rather strongly sinuate behind, the hind angles acute 
and directed outwards; elytra strongly convex, comparatively broad, long, subparallel to beyond the 
middle, the scutellar region depressed, the humeri a little prominent in front, with. rows of rather fine 
slightly elongate impressions, the impressions distant one from another and gradually becoming very much 
finer and shallower towards the apex, the interstices quite flat and almost smooth; anterior and intermediate 
tibie each with a sharp triangular tooth, and the posterior tibia with two or three small teeth on the 
inner side some distance before the apex, in the male ; beneath very sparingly and finely, the flanks of the 
prothorax very coarsely and closely, punctured, the sides of the metasternum and side pieces with scattered. 
shallow coarse impressions. 
Length 93-94 millim. (¢.) 
Hab. Mexico, Jalapa (Hége); British Honpuras, R. Hondo (Blancaneauz). 
Two male examples. This species can only be compared with 7’. levipennis, from 
which it is separated by its larger size and subopaque surface; the thorax is more 
coarsely punctured, and with much more acute hind angles; and the elytra are broader, 
longer, and more parallel, and with the punctures coarser, more elongate, and more 
distant one from another. 
4. Talanus lecontei. 
Elongate, subcylindrical, varying in colour from dark brownish-castaneous to castaneous, with a slight bronzy 
tint, shining. Head closely and moderately finely punctured, deeply transversely impressed in front ; 
antenne stout, reaching to a little beyond the base of the prothorax, joint 7 much wider than 6 and sub- 
transverse, joints 8-10 wider than 7, almost equal in width and transverse, the apical joint ovate and 
half as long again as the tenth, piceous, the three or four basal joints and the apex ferruginous, sometimes 
entirely ferruginous ; prothorax a little narrowed and sinuate behind, the hind angles rectangular, the 
surface coarsely and rather closely punctured, the dise with a shallow transverse impression some distance 
before the base, the impression extending more or less distinctly on each side to the lateral margin; elytra 
long, subparallel, with rows of coarse slightly elongate impressions placed upon almost obsolete striee, the 
impressions somewhat closely placed and becoming gradually finer towards the apex, the interstices flat 
and exceedingly minutely punctured ; legs varying in colour from piceous to ferruginous ; the tibie in the 
male each with a sharp triangular tooth on the inner side some distance before the apex; beneath very 
sparingly and minutely, the flanks of the prothorax and the metasternum narrowly at the sides, and the 
side pieces very coarsely, punctured. 
Length 43-64 millim. (¢ 2.) 
Hab. Mexico, Vera Cruz (Sallé), Jalapa, Cordova, Teapa in Tabasco (Hége) ; Britisy 
Honpvuras, Belize, R. Hondo, R. Sarstoon (Blancaneaux) ; GUATEMALA, Panzos, San Juan 
in Vera Paz, Chiacam, Cahabon (Champion).
