LOBOPODA. | 393 
not very closely placed punctures on each side, the apices in the female slightly thickened and divergent ; 
beneath piceous, almost glabrous, sparingly but somewhat coarsely punctured, the metasternum more 
closely so in the middle in the male, the fifth ventral segment broadly impressed in the centre in both 
sexes; legs and antenne dark castaneous. 
g. Anterior tibiee broadly and subangularly dilated on the inner side a little beyond the middle, the dilated 
part concave within ; anterior femora with a short tooth a little before the middle. The lateral lobes of 
the last ventral segment somewhat spoon-shaped, very long, and inwardly curved, the upper edges very 
finely serrate and the lower edges clothed with long fine hairs within ; the central sheath broad, narrowing 
to the apex. (Fig. 6a.) 
Length 15-16 millim.; breadth 5-53 millim. (¢ 2.) 
Hab. Panama, Caldera in Chiriqui 1200 feet (Champion). 
Two examples. This species is distinguished by its large size and deeply impressed 
thorax, and by the elytra being comparatively broad towards the base. 
8. Lobopoda mucronata. (Tab. XVII. fig. 7, 9.) 
Moderately elongate, broad, piceous-black, shining, sparsely pubescent. Head with scattered, rather coarse, 
punctures; eyes ( 2 ) comparatively rather large, somewhat narrowly separated ; prothorax broad, coarsely 
and moderately closely punctured, the disc canaliculate, with a rounded impression on each side about the 
middle, and broadly transversely impressed before the base, the basal impression deep and connecting 
the fovex, the hind angles a little prominent and directed outwards though somewhat obtuse; elytra 
moderately long, broad, deeply striate, the strie closely punctate, the interstices convex, and with a row 
of distantly placed punctures on each side, the apices produced into a rather long mucro in the female ; 
beneath more shining, sparingly but rather coarsely punctured, the fifth ventral segment broadly impressed 
in the middle; legs and antenne ferruginous. 
Length 144 millim.; breadth 53 millim. ( 9.) 
Hab. Panama, Bugaba (Champion). 
One example. Closely allied to L. panamensis, and differing as follows:—The eyes 
(in the female) are more narrowly separated; the thorax is more closely punctured, 
and has the impressions rather deeper; and the elytra are sharply mucronate at the 
apex. LL. mucronata is perhaps a variety of L. panamensis, but in the absence of the 
male it is impossible to say for certain; the strongly mucronate apices of the elytra 
may prove to be a variable character, as it is in L. mexicana. 
9. Lobopoda apicalis. (Tab. XVII. figg. 8, 8 a.) 
Elongate, brownish-piceous or black, shining, rather thickly pubescent. Head sparingly but rather coarsely 
punctured; eyes very large and approximate in the male, rather smaller and very narrowly separated in 
the female; prothorax rather finely and very sparsely punctured, widest at the base, the disc shallowly 
canaliculate, and broadly transversely impressed before the base, the basal fovee deep, the sides a little 
sinuate behind, the hind angles rectangular or subacute; elytra long, somewhat deeply striate, the striz 
with rather coarse impressions throughout, the impressions closely placed and rounded in shape from the 
base to the middle and thence to the apex elongate and more scattered, the interstices rather convex and 
sparingly punctured, the apices slightly pointed in the female; beneath sparingly and somewhat coarsely 
punctured, the fifth ventral segment impressed in the middle in both sexes; legs dark reddish-brown or 
piceous, the tibize and tarsi more or less ferruginous ; antenne ferruginous, the three basal joints darker. 
é; major. Anterior tibie strongly triangularly widened on the inner side a little beyond the middle; anterior 
femora armed with a short tooth. The lateral lobes of the last ventral segment broad and short, some- 
what extended laterally, and each armed at the apex with two short curved processes, the outer one of
