400 HETEROMERA. 
22. Lobopoda opaca. (Tab. XVII. figg. 23, 23a, ¢ .) 
Moderately elongate, broad, dull black, thickly clothed with cinereous pubescence. Head coarsely and irre- 
gularly punctured; eyes moderately large, separated by a narrow space in the male; prothorax widest at 
the base, slightly sinuate at the sides behind, somewhat coarsely, irregularly, and rather closely punctured, 
the disc obsoletely canaliculate, and broadly longitudinally impressed before the base, the basal fovese deep ; 
elytra broad towards the base, gradually narrowing behind, with rows of rather coarse, oblong, not very 
closely placed impressions, the interstices flat throughout and finely punctured; beneath sparsely and 
somewhat coarsely punctured, the middle of the metasternum behind more closely so in the male; legs 
piceous, the tarsi fusco-ferruginous; antenne fusco-ferruginous. 
g. Anterior tibie slightly widened on the inner side before the middle. The lateral lobes of the last ventral 
segment short and broad, curved, and spoon-shaped, the lower edge clothed with short hairs; the 
central sheath acuminate, the apical portion horizontal, and setose beneath, the apex slightly thickened.

Length 113 millim.; breadth 4} millim. (<¢.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
One male example. This species possesses a different facies from any other of the 
genus here enumerated, except the following, from which it is at once separated by 
the diverse sculpture of the elytra. The elytra have merely rows of oblong punctures 
placed upon almost obsolete striz, and the interstices are flat throughout. 
23. Lobopoda opacicollis. 
Moderately elongate, rather broad, dull brownish-black, the elytra slightly shining, thickly clothed with greyish- 
fulvous pubescence. Head somewhat coarsely and closely punctured, the punctures shallow; eyes (2) 
moderately large and rather widely separated; prothorax with the sides slightly sinuate or almost straight 
behind, the hind angles varying in shape from obtusely rectangular to subacute, the disc broadly longi- 
tudinally impressed in the middle behind and obsoletely canaliculate, the basal fovese deep, the surface . 
opaque, very irregularly, somewhat coarsely (but shallowly), and rather closely punctured; elytra more 
shining than the prothorax, moderately broad, narrowing very little in their basal half, with finely and 
closely punctured, narrow, rather deeply impressed striz, the interstices feebly convex and finely punc- 
tured; beneath sparsely and finely punctured; legs and antennee fusco-ferruginous, the femora and tibie 
often darker. 
Length 10-113 millim.; breadth 33-4 millim. (9.) 
Hab. Mexico, Cordova, Guanajuato (Sallé), Jalapa (Hége); British Honpuras 
(Blancaneauz). 
Six examples, all females. This species can only be satisfactorily compared with the 
preceding ; it has, however, very differently sculptured elytra. Labelled Z. sulcati- 
pennis, Dugés, in the Sallé collection—a very inapplicable name, and one that I 
cannot adopt, 
24, Lobopoda hirta. 
Elongate, rather convex, brownish-castaneous, rather dull, thickly pubescent. Head with the vertex very 
closely, the epistoma more sparingly and more coarsely, punctured; eyes moderately large, separated by 
a narrow space in the male; prothorax convex, broadly and shallowly canaliculate (except in front), 
deeply impressed in the middle before the base, the basal fovese very deep, the surface very closely and 
shallowly but somewhat coarsely punctured; elytra subparallel anteriorly, gradually narrowing from a 
little before the middle, with rows of not very closely placed, oblong, moderately coarse impressions, the
