narrowing and produced towards the apex, and armed with a few short coarse sete beneath, the extreme 
apex a little widened and rounded. (Fig. 14a.) 
Length 84-10 millim.; breadth 3}-33 millim. (d 2.) 
Hab. Panama, Bugaba, Volcan de Chiriqui, La Caldera (Champion). 
Three examples. From ZL. obsoleta and L. cariniventris this species may be distin- 
guished by its rather larger size, smoother thorax, and the much more deeply striate 
elytra, &c.; the apical interstices of the latter are very sharply raised. 
44, Lobopoda —— ? 
Hab. Costa Rica, Cache (Logers). 
A single male example of a species no doubt belonging to this genus, and perfectly 
distinct from any other here enumerated; the unique individual is without head. The 
following is a brief description :— 
Elongate, narrow, subparallel, sparsely pubescent, dark bronze, shining; prothorax sparsely but somewhat 
coarsely punctured, the sides almost straight behind, the disc shallowly canaliculate; elytra subparallel 
in their basal half, with closely and rather coarsely punctured striz, the striz deep towards the apex, the 
interstices feebly convex and very sparsely punctured; beneath with scattered coarse punctures, the 
metasternum very coarsely punctured at the sides and closely and more finely so in the middle. 
¢. Anterior femora incrassate, the anterior tibiae widened on the inner side before the middle; the lateral 
lobes of the last ventral segment broad, long, and curved, spoon-shaped, broadly rounded at the apex ; 
the central sheath gradually narrowing behind, and rounded at the apex. 
Length 11 millim.; breadth 33 millim. (<.) 
TEMNES. 
Last joint of the labial palpi broad, triangular ; last joint of the maxillary palpi very stout, broadly triangular, 
its apical side longer than the outer; mandibles bifid, very deeply cleft ; labrum very prominent, rather 
broader than the epistoma ; eyes moderately large, widely separated ; antenne rather short, moderately 
slender, subfiliform, the intermediate joints the widest, joint 3 about four times as long as 2, and longer and 
narrower than 4, joints 4-11 gradually decreasing in length ; prothorax transverse, subquadrate, rather 
convex, the sides feebly margined, the margins not visible from above; elytra much wider than the pro- 
thorax ; intercoxal process narrowly triangular ; anterior and intermediate tarsi with the third and fourth 
joints strongly and equally, and the posterior tarsi with the penultimate joint, lobed beneath ; first joint 
of the posterior tarsi long, as long as the following three joints united; fifth ventral segment in the male 
abnormal; prosternum abruptly declivous behind; body oblong ovate, hirsute. 
The single species included in this genus has much the facies of certain forms of 
Lystronychus or Xystropus ; it is, however, at once separated by the very deeply cleft 
mandibles, broadly lobed tarsi, and other particulars noticed above. 
T. ceruleus has 
very remarkable male characters. 
1. Temnes ceruleus. (Tab. XVIII. figg. 15, 3; 15a, mandible.) 
Oblong ovate, rather convex, bright metallic cxruleous with a violaceous tinge, thickly clothed with long 
bristly hairs. Head coarsely and rather sparsely punctured; prothorax convex, transverse, the sides 
rounded in front and straight from before the middle to the base, the hind angles rectangular, the basal 
foves small and very short (in great part hidden by the convexity of the surface), the disc unimpressed
