394 HETEROMERA. 
which is obliquely truncate and furnished with numerous long hairs; the central sheath rather broad, 
gradually narrowing, its apical portion horizontal, long, and armed with very short sete at the sides and 
beneath. (Figg. & 8a.) 
3, minor. Anterior tibie merely sinuous within ; anterior femora unarmed. 
Length 124-15 millim.; breadth 44-5 millim. (d 2.) 
Hab. Guatemata, Capetillo (Champion). 
Four examples, three males and one female. This species resembles L. tristis &c., 
but is easily separated by the punctures of the striae being elongate in shape on the 
apical half of the elytra. The cedeagus in its complicated structure closely resembles 
that of L. seriata. 
10. Lobopoda atrata. (Tab. XVII. figg. 9, 9 a.) 
Elongate, piceous-black, slightly shining, thickly pubescent. Head with scattered shallow punctures; eyes 
large and approximate in the male, rather narrowly separated in the female ; prothorax closely, subequally, 
and somewhat coarsely punctured, the disc shallowly canaliculate, and shallowly transversely impressed 
before the base, the basal fovea rather deep, the hind angles subrectangular; elytra rather broad towards 
the base, rapidly narrowing from a little below the shoulders, with moderately deep and closely punctured 
strice, the interstices slightly convex and somewhat closely punctured ; beneath sparsely and rather coarsely 
punctured, the metasternum in the middle behind closely so in the male; legs piceous, the tibie and 
tarsi more or less ferruginous; antenne ferruginous. 
3. Anterior tibie subangularly widened on the inner side towards the base. ‘The lateral lobes of the last 
ventral segment long, broad, twisted and spoon-shaped beyond the middle, and abruptly narrowed and 
incurved at the apex; the central sheath narrow, the apical portion elongate-triangular, and slightly 
setose at the sides and beneath. (Figg. 9, 9a.) 
Length 123-13 millim.; breadth 4-4? millim. (¢ 2.) 
Hab. Nicaragua, Chontales (Janson, in coll. F. Bates); Panama, Volcan de Chiriqui 
(Champion). 
Two examples. The comparatively close punctuation and the less acute hind angles 
of the thorax, the less convex interstices at the apex of the elytra, the non-excavate 
fifth ventral segment in the male, and the differently shaped cedeagus easily distinguish 
this species from Z. acutangula, which it otherwise somewhat closely resembles. 
The single example (female) from Nicaragua has the thorax more finely punctured 
than in the male individual from the State of Panama. 
11. Lobopoda subparallela. (Tab. XVII. fig. 10.) 
Elongate, black, rather dull, somewhat thickly pubescent. Head with the vertex very closely (almost rugu- 
losely), the epistoma rather sparsely, punctured; eyes moderately large, separated by a narrow space 
in the male; prothorax convex in front, the sides straight behind, the hind angles more or less 
rectangular, the disc slightly impressed before the base, the basal foves shallow, the surface coarsely and 
closely punctured; elytra long, subparallel in their basal half, with shallow, closely punctured strie, the 
interstices feebly convex, almost flat on the basal half of the disc, and coarsely punctured ; beneath coarsely 
and sparsely punctured, the metasternum in the middle behind closely so in the male; legs and antenne 
brownish-piceous, the tarsi more or less ferruginous. 
g. Anterior tibie sinuous within. The lateral lobes of the last ventral segment moderately long, inwardly 
curved, concave, and sparsely and finely setose within, and broadly rounded at the apex; the central
