HETEROMERA. 
** Upper surface dark bronze, the elytra of a lighter eneous tint. 
3. Lobopoda asperula. (Tab. XVII. figg. 2, 24, 6, ¢ -) 
Elongate, broad, brownish-bronze, the elytra lighter in tint and with a more distinct eneous tinge and 
more shining, thickly clothed with ashy pubescence. Head coarsely and irregularly, but rather sparsely, 
punctured; eyes moderately large, rather widely separated in the male, separated by a broad space in the 
female; prothorax broad, narrowing from the base, the sides rather strongly sinuate behind, the hind 
angles subacute and extending outwards (reaching almost as far outwardly as the humeri), the disc 
obsoletely canaliculate (except in front), impressed in the middle before the base, and with a shallow 
irregular impunctate depression on each side about the middle, the basal fovese very deep, the surface 
closely, coarsely, and irregularly punctured: elytra long and broad, subparallel in their basal third, 
gradually narrowed beyond, somewhat broadly rounded behind, comparatively deeply impressed at the 
base on each side within the humeri, with very finely and closely punctured stri, the strie very lightly 
impressed, the interstices each with an ill-defined, much interrupted, and rather sinuous series of feeble 
longitudinal elevations, almost flat on the basal half of the disc, and with a few scattered punctures, the 
punctures not much finer than those of the strie; beneath sparsely and moderately coarsely punctured, 
the middle of the metasternum behind more closely so in the male; legs stout, fusco-ferruginous, the 
femora darker and seneous in tint; antennee fusco-ferruginous. 
¢. Anterior tibie angularly widened on the inner side before the middle. The fifth ventral segment deeply 
and semicircularly excavate in the middle at the apex. The lateral lobes of the last ventral segment long, 
strongly sinuous (though parallel if viewed from beneath), the apices produced and recurved upwards, 
forming a sort of hook, and almost pointed; the central sheath broad, gradually narrowing, the extreme 
apex recurved and somewhat hooked. (Figg. 2a, 20.) 
Length 124--17 millim.; breadth 54 millim. (¢ 2.) 
Hab. Mexico (coll. F. Bates), Yucatan (Sallé, Gawmer). 
A large number of examples of both sexes. In the peculiar sculpture of the elytra 
this species somewhat resembles L. gigantea, though it is very different in shape. 
Labelled Z. asperula, Deyr., in the Sallé collection, and J. senex, Dup., in Mr, F. 
Bates’s collection. 
Sect. II. Anterior (and in several species the intermediate) tarsi in the male with the 
four basal joints more or less lobed beneath, the penultimate joint of the 
anterior and intermediate pairs strongly so in both sexes; prosternum 
abruptly declivous behind. (Lobopoda, Sol., Lacord.) 
a. Body pubescent. 
* Upper surface black, piceous, or reddish-brown. 
+ Anterior and intermediate tarsi in the male with the four basal joints lobed beneath. 
4. Lobopoda acutangula, (Tab. XVII. fige. 3, 3a.) 
Elongate, moderately broad, brownish-piceous or black, shining, rather sparsely pubescent. Head with 
scattered moderately coarse punctures; eyes large and approximate in the male, rather smaller and mode- 
rately widely separated in the female; prothorax sparsely and somewhat coarsely punctured, the disc 
indistinctly canaliculate, and transversely impressed before the base, the basal foves deep, the sides a 
little sinuate before the base and somewhat rapidly converging from the more or less acute outwardly 
directed hind angles, the latter extending laterally as far as the humeral angles of the elytra; elytra
