322 HETEROMERA. 
1. Species winged. 
A. Antenne comparatively short, the ninth and tenth joints more or less transverse. 
a. Elytra with rows of impressions placed upon shallow or obsolete strie ; the interstices 
flat (in T. interstitialis convex at the apex, and the striw in consequence deeper 
behind). 
1. Talanus neotropicalis. (Tab. XIV. fig. 1, ¢.) 
Elongate, subcylindrical, brownish-castaneous or castaneous, with a slight eneous tinge, shining. Head rather 
closely and somewhat coarsely punctured, deeply transversely impressed in front; antenne stout, about 
reaching to the base of the prothorax, widening outwardly, joints 8-10 wider than 7 and equal in width, 
9 and 10 transverse, the apical joint ovate and fully twice as long as and rather wider than 10, black, the 
three or four basal joints and the extreme apex ferruginous; prothorax very convex, the sides a little 
constricted behind, the disc shallowly transversely impressed before the base, the hind angles subrectangular, 
the surface very coarsely and somewhat closely punctured, an oblique slightly impressed space on each 
side some distance before the base more sparingly punctured; elytra comparatively very long, parallel, 
with rows of rather coarse rounded impressions placed upon almost obsolete striw, the impressions 
becoming coarser and a little more distant one from another towards the base and much finer and closer 
towards the apex, the interstices flat and almost smooth ; legs brownish-piceous, the femora often more or 
less castaneous; anterior and intermediate tibize each with a triangular tooth, and the posterior tibiee with 
two small teeth (the hinder one of which is sometimes obsolete) on the inner side some distance before the 
apex, in the male; beneath shining, very finely and sparingly, the sides of the metasternum and side 
pieces and the flanks of the prothorax very coarsely, punctured. 
Length 8-9 millim. (¢ 9.) 
Hab. Guatemata (colls. F. Bates, Brit. Mus.), El Reposo, San Gerénimo (Champion) ; 
Costa Rica (Sallé, coll. F. Bates)—Braziu, Rio Janeiro. 
Numerous examples, ‘This species is closely allied to the Cuban 7. cribrarius, Jacq. 
Duv., but larger, longer, and more or less castaneous in colour; the thorax rather 
broader; the elytra relatively longer, and with the punctures not quite so closely placed 
and finer and shallower posteriorly ; the antenne stouter, &c.; the tibie are similarly 
armed in the male, but with the teeth rather finer. 
A specimen from Rio Janeiro in Mr. F. Bates’s collection appears to be conspecific 
with our insect. 
An example from San Gerdnimo is figured. 
2. Talanus levipennis. 
Allied to 7’, neotropicalis, and differing as follows :—the antenne not quite so stout, and with the apical joint 
rather shorter; the head more finely punctured; the prothorax very much more finely, more shallowly, 
and more sparingly punctured, and rather strongly obliquely impressed on each side some distance beyond 
the middle, the sides & little constricted behind, the hind angles fine and acute; the elytra much shorter, 
narrowing from the middle, and almost elongate-ovate in form (not parallel), with rows of very shallow 
fine impressions, the impressions still finer towards the apex (not coarser towards the base, as in 7’. neo- 
tropicalis), the interstices quite flat and almost smooth, and the humeri more rounded ; the legs smoother ; 
the upper surface brownish-bronze in tint; the under surface as in 7’. neotropicalis. j 
Length 8-8} millim. ( 9.)
