TALANUS. 327 
intermediate pair the longest) on the inner side some distance before the apex ; beneath sparingly and 
very finely, the flanks of the prothorax very coarsely, punctured. 
Length 43-6 millim. (¢ 2.) 
Hab. Guatemata, Cerro Zunil, Las Mercedes (Champion). 
Six examples. Allied to 7. ewnetpennis, from which it is separated by the more 
ovate and more convex elytra, and the interstices convex towards the apex (in 
T. eneipennis they are flat throughout) ; the flanks of the prothorax more sparingly but 
still more coarsely punctured; and the metasternum almost without coarse impressions 
at the sides. 
** Interstices flat. 
10. Talanus ater. 
Elongate, subcylindrical, black, with a very slight bronzy tint, shining. Head closely and rather finely punc- 
tured, deeply transversely impressed in front; antenne moderately stout, joints 8-10 wider than 7 and 
equal in width, 9 and 10 transverse, the apical joint nearly twice as long as the tenth and somewhat 
bluntly rounded at the apex, black ; prothorax very slightly sinuate at the sides behind the middle, the 
hind angles acute and directed outwards, the surface coarsely and somewhat closely punctured, more 
sparingly so at the sides behind, a shallow transverse impression on the disc before the base, the impression 
obliquely extending on each side to the lateral margin ; elytra moderately long, subparallel in their basal 
half, finely and very lightly striate, the striz with fine, slightly elongate, closely placed impressions, the 
impressions becoming coarser towards the base and shallower towards the apex, the sutural stria 
(except at the base) and the fifth and sixth strie in their basal fourth more deeply impressed, the inter- 
stices flat and almost smooth; legs comparatively smooth, shining, black; beneath very finely and 
sparingly, the flanks of the prothorax very coarsely, punctured, the sides of the metasternum and side 
pieces with coarse impressions. 
Length 63; millim. (9.) 
Hab. Panama, Bugaba (Champion). 
One female example. This species is distinguished from all the others of the genus 
here recorded by the finely and lightly striate elytra, the strie finely and shallowly 
punctured ; and also by its shining black colour. 
11. Talanus zneipennis. 
Elongate, subcylindrical, brownish-bronze, the elytra seneous in tint, shining. Head, antenna, and prothorax 
much as in 7’. guatemalensis; elytra subparallel to beyond the middle, lightly but distinctly striate, the 
strie with rather fine, closely placed, elongate impressions, the impressions coarser towards the base and 
shallower towards the apex, the interstices flat and almost smooth; the male tibiz and under surface as 
in 7. guatemalensis. 
Length 5-53 millim. (d 9.) 
Hab. Mexico, Tuxtla (Sallé); British Honpuras, Belize (Blancaneauz). 
Three examples. The neous tint, flat interstices, and more lightly and finely 
punctate-striate elytra sufficiently distinguish this species from T. subexaratus; the 
above-mentioned differences and the rather narrower thorax separate it from 7. guate- 
malensis.
