LOBOPODA. 397 
comparatively wide in front, the sides slightly sinuate behind, the hind angles rectangular, the disc very 
shallowly canaliculate behind, the basal foves quite shallow, the surface very closely, subequally, and 
somewhat coarsely (though shallowly) punctured ; elytra long, gradually narrowing almost from the base, 
with closely punctured strie, the interstices feebly convex and rather finely and somewhat closely 
punctured; beneath rather sparsely punctured ; legs and antenne ferruginous, the femora darker. 
g. Anterior tibie simple. The lateral lobes of the last ventral segment short and stout, broad at the base, 
and each with a subangular laterally projecting piece above near the end, the apex blunt, the inner edge 
closely and finely serrate ; the central sheath gradually narrowing to the apex, the apical portion elongate, 
horizontal, and finely setose at the sides, the apex blunt. (Figg. 14a, 0.) 
Length 103-113 millim.; breadth 3-33 millim. (<¢.) 
Hab. Guatemata, Capetillo (Champion). 
Two male examples. This species is readily separated from most of its allies by the 
very closely punctured thorax. 
16. Lobopoda yucatanica. (Tab. XVII. figg. 15, 15 a.) 
Moderately elongate, dull brownish-piceous, thickly pubescent. Head closely and somewhat coarsely punctured : 
eyes (3) very large and approximate ; prothorax wide in front, the sides straight behind, the hind angles 
rectangular, the disc almost unimpressed, the basal foves very shallow, the surface finely and densely 
punctured ; elytra moderately long, gradually narrowing from a little below the base, with finely and 
closely punctured striw, the interstices feebly convex and finely and thickly punctured; beneath some- 
what closely and rather coarsely punctured, the metasternum (¢ ) densely so in the middle behind ; legs 
and antenne brownish-ferruginous, the former short. 
¢$. Anterior tibiz subtriangularly widened on the inner side before the middle. The lateral lobes of the last 
ventral segment short, and with a slender club-like prolongation at the end; the central sheath gradually 
narrowing to the apex, the latter blunt. (Figg. 15, 15a.) 
Length 81 millim.; breadth 3 millim. (¢.-) 
Hab. Mexico, Temax in N. Yucatan (Gaumer). 
One male example. This species is allied to Z. puncticollis; but differs in its duller 
surface, more densely punctured thorax, shorter legs, more closely punctured under 
surface, and male characters. 
17. Lobopoda attenuata. (Tab. XVII. fig. 16.) 
Moderately elongate, dark brownish-piceous or black, shining, thickly pubescent. Head with scattered rather 
coarse punctures; eyes large and approximate in the male, moderately widely separated in the female ; 
prothorax rather closely but somewhat coarsely (though shallowly) punctured, the disc obsoletely canali- 
culate, and shallowly transversely impressed before the base, the basal fovee rather shallow, the hind 
angles rectangular; elytra rapidly narrowing from a little below the base, with rather deep and closely 
punctured striz, the interstices feebly convex, a little more strongly so at the apex, and somewhat 
coarsely punctured, the apices rounded in both sexes ; beneath sparingly but somewhat coarsely punctured ; 
legs and antenne more or less ferruginous, the femora darker. 
. Anterior tibie triangularly widened on the inner side before the middle. The lateral lobes of the last 
ventral segment long, inwardly curved, and somewhat spoon-shaped, a little dilated on the upper 
side at the apex; the central sheath narrow, gradually narrowing behind, the apex slightly dilated.

Length 84-10 millim. ; breadth 3-31 millim. (d 2.) 
Hab. Guatemata, Capetillo (Champion); Nicaracua, Chontales (Belt).
