TALANUS. 325 
In general facies this insect perhaps more nearly resembles 7. levipennis; it will be 
known, however, from that species by its much smaller size and narrower form; the 
thorax differently shaped and more closely punctured, and with a deep basal impression ; 
and the punctures on the basal half of the elytra more deeply impressed. 
The small variety (a single immature male) is analogous to the small form of 
L. lecontei. | 
Our examples vary in size from 43-64 millim. 
b. Elytra punctate-striate, the strie more distinctly impressed. 
* Interstices more or less convex. 
7. Talanus laticeps. (Tab. XIV. fig. 2, ¢.) 
Elongate, rather depressed, dark ferruginous, the elytra a little lighter, moderately shining. Head broad, very 
shallowly, finely, and sparingly punctured, the frontal transverse impression broad and moderately deep ; 
eyes widely separated, strongly transversely convex and projecting laterally ; antenne moderately stout, 
joints 8-10 wider than 7, equal in width and decreasing a little in length outwardly, the apical joint ovate 
and about twice as long as the tenth, ferruginous ; prothorax very acutely margined, the sides strongly 
narrowed and sinuate behind and rounded anteriorly, the hind angles subacute, the surface very coarsely 
and closely punctured, the disc with a very deep transverse impression (not extending to the lateral 
margins) before the base ; elytra rather broad, depressed on the disc, subparallel in their basal half, deeply 
striate throughout, the striz with coarse elongate very closely placed impressions, the interstices convex 
(still more strongly so at the sides and apex) and almost smooth; legs ferruginous, the tarsi beneath, and 
the tibize on the inner side towards the apex, thickly clothed with fulvous hair; the anterior and inter- 
mediate tibi each with a sharp triangular tooth some distance before the apex, and the posterior tibie 
with three or four teeth in their apical third, on the inner side, in the male; beneath more shining, 
rather sparingly but comparatively coarsely punctured, the sides (broadly) and the front of the metasternum 
much more coarsely so, the flanks of the prothorax very coarsely punctured. 
Length 7-8; millim. (<¢.) 
Hab. Panama (coll. FP. Bates). 
Two male examples. ‘This species is separated from all the others here recorded by 
the very broad and comparatively smooth head; the transverse, very convex, widely 
separated, and laterally projecting eyes ; the acutely margined and posteriorly constricted 
thorax, with very deep basal impression ; the coarsely and deeply punctate-striate elytra, 
with the interstices convex, and the disc flattened; the comparatively coarsely punc- 
tured under surface; and the strongly pronounced male characters. The tarsi and 
tibie are more thickly clothed with hair than in the allied forms, the hair on the 
tibie almost hiding the teeth from view.
