This is the commonest and most widely distributed species of the genus in our region ; 
it agrees sufficiently well with Miklin’s description! to be identified therewith. 7’. subex- 
aratus will be known from T. lecontei and its allies by the elytra being shorter, broader, 
less parallel, and comparatively very deeply and coarsely punctate-striate, the interstices 
smooth and more or less convex (sometimes flatter on the basal half of the disc); the 
antenne about reaching to the base of the thorax, widening towards the apex, and 
with the ninth and tenth joints more or less (in some specimens strongly) transverse. 
Maklin’s description of this (and also of his other) species is based upon very insuffi- 
cient material. The long series of upwards of seventy examples before me vary greatly 
in size, colour, and sculpture, and apparently, at first sight, represent several species ; 
but as the different forms were collected together in several localities, and are more 
or less connected one with another, I prefer to regard them as representing one very 
variable species. 
In addition to the rufo-ferruginous variety « (common to several other species of the 
genus), noticed by Maklin}, I here indicate one other :-— 
Var. B. Elytra rather longer, the striz not so deeply impressed, the punctures still coarser and more scattered 
and more elongate in form. 
Hab. Panama, Volcan de Chiriqui (Champion). Two examples (¢ @ ). 
In some few examples the inner side of the posterior tibize of the male is finely and 
irregularly serrate towards the apex, instead of being armed with a small triangular 
tooth, as is usually the case. ‘The hind angles of the thorax are usually rectangular, 
occasionally acute. Our specimens vary in size from 5-74 millim. 7. humilis, Makl., 
from Colombia, to judge from the description, may possibly be a small form of this 
variable insect. 
9. Talanus guatemalensis, (Tab. XIV. fig. 3, 3.) 
Elongate, convex, brownish-piceous, the elytra neous in tint, shining. Head closely and coarsely punctured, 
the transverse frontal impression deep; antenne reaching to a little beyond the base of the prothorax 
joints 8-10 wider than 7 and about equal in width, the tenth transverse, the apical joint ovate and 
nearly twice as long as the preceding, piceous, with the basal joints ferruginous, or entirely ferruginous ; 
prothorax coarsely and somewhat closely punctured, more sparingly so on the disc and towards the base. 
the sides a little narrowed and sinuate behind, the hind angles rectangular or subacute, a transyerc 
impression extending to the lateral margins some little distance before the base ; elytra comparatively 
rather short, convex, somewhat ovate in form, widest in the middle, distinctly punctate-striate, the 
impressions rather fine, elongate, coarser towards the sides, and finer and shallower on the posteriie 
half of the disc, the interstices flat (or nearly so) on the disc, a little convex outwardly and towards 
the apex, and almost smooth; the tibie in the male each with a sharp triangular tooth (that on the
