398 HETEROMERA. 
Three males from Guatemala, and a pair from Nicaragua. The latter differ from the 
others in being rather less elongate in shape; but as the cedeagus of the male agrees 
precisely in structure with that of the Guatemalan insect, 1 have no doubt of its specific 
identity. 
‘L. attenuata resembles L. acutangula and L. atrata in shape ; it is, however, more 
nearly allied to the latter, from which its narrower shape and much smaller size, and 
the differently-shaped cedeagus of the male, distinguish it. 
18. Lobopoda tropicalis. (Tab. XVII. fig. 17.) 
Moderately elongate, brownish-piceous, rather shining, somewhat thickly pubescent. Head with scattered 
coarsish punctures ; eyes large and approximate in the male; prothorax sparsely and rather coarsely (but 
shallowly) punctured, the disc very distinctly canaliculate, and shallowly transversely impressed before 
the base, the basal fovee not very deep, the hind angles rectangular; elytra moderately long, with 
closely punctured striw, the interstices feebly convex and somewhat coarsely punctured ; beneath sparsely 
and rather coarsely punctured, the metasternum in the middle behind closely so in the male; legs and 
antenne dark ferruginous, the former thickly clothed (especially on the inner side of the femora and tibie) 
with hairs. 
3. Anterior tibie simple. The lateral lobes of the last ventral segment long and curved, the apical portion 
widened and of a flattened spatulate shape, nearly straight, and clothed with very long hairs, the inner 
edge minutely serrate; the central sheath rather broad, gradually narrowing behind, the apex abruptly 
truncate. (Fig. 17.) 
Length 104 millim.; breadth 3$ millim. (<¢.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
A single male example. This species is of about the size and shape of L. attenuata ; 
but it is readily distinguished by the more sparsely punctured and more distinctly 
canaliculate thorax, the simple anterior tibie in the male, &c. The legs are clothed 
with more numerous and longer and more bristly hairs than in the allied forms. In 
the structure of the cedeagus L. tropicalis departs widely from any other species here 
enumerated. 
19. Lobopoda femoralis. (Tab. XVII. figg. 18, 18a, 3.) 
Rather short, varying in colour from fusco-ferruginous to brownish-piceous, dull, thickly pubescent. Head 
rather sparsely but somewhat coarsely punctured; eyes large and subapproximate in the male, much 
smaller and widely separated in the female; prothorax somewhat thickly and rather coarsely (though 
shallowly) punctured, the disc very distinctly canaliculate, and slightly impressed before the base, the 
basal fovez rather shallow, the hind angles rectangular; elytra rather short, comparatively wide towards 
the base and somewhat rapidly narrowed behind, with very closely punctured strie, the interstices feebly 
convex and moderately coarsely punctured ; beneath sparsely and rather finely punctured, the metasternum 
in the middle very closely so in the male; legs testaceous or fusco-testaceous, with the inner apical third 
of the femora piceous or black, rarely brownish-piceous with the tibie and tarsi more or less ferruginous ; 
antenne slender, testaceous or ferruginous. 
3. Anterior tibiee more or less angularly widened on the inner side just before the middle, and between this 
and the apex emarginate. The lateral lobes of the last ventral segment very long, curved and angularly 
extended on the outer side towards the apex, and then again abruptly curved inwards, the apical portion 
broadly triangular, and with its apex parallel with the lobe; the central sheath very broad, somewhat
