LOBOPODA. A407 
3. Anterior tibie sinuous, very distinctly widened on the inner side about the middle; anterior and inter- 
mediate tarsi with the four basal joints lobed beneath. Metasternal depression deep, rather closely 
punctured within. Second ventral segment carinate down the middle, the third segment very feebly so 
towards the base, the fifth segment unimpressed. The lateral lobes of the last ventral segment rather 
short, wide at the base, and narrowing and inwardly curved outwardly, the apices blunt, the inner edges 
denticulate; the central sheath rather broad, the apical portion somewhat spoon-shaped, the apex slightly 
widened but narrowing and bent a little downwards in front. (Fig. 9 a.) 
Length 94 millim.; breadth 33-33 millim. (¢ 9.) 
Hab. Costa Rica, Volcan de Irazu 6000 to 7000 feet (Rogers). 
T'wo examples. This species is distinguished by its subparallel shape, eneous surface, 
very finely and closely punctured elytral striae, flat interstices, and remarkable sexual 
characters; in this last respect it approaches Z. cariniventris. 
L. wrazuensis is not very 
nearly allied to any other species of the genus known to me. 
_ 38. Lobopoda nitida. 
Rather short, somewhat convex, bright eneous, glabrous. Head with scattered coarsish punctures ; eyes (9) 
moderately large, rather widely separated ; prothorax convex, the sides straight behind, the hind angles 
rectangular, the disc finely canaliculate behind, and a little flattened in the middle before the base, the 
basal fovere small but deep, the surface finely and moderately closely punctured ; elytra rather short, a 
little rounded at the sides, gradually narrowing from a little before the middle, with narrow but deep 
striz, the strie with oblong, rather distantly placed, coarsish punctures which (like the stris) become 
shallower towards the apex, the interstices flat and almost impunctate; beneath brownish-piceous, the 
metasternum coarsely and rather closely punctured all over, the ventral surface smooth and almost 
impunctate ; legs very sparsely pilose, ferruginous, the femora darker; antenna ferruginous. 
Length 7 millim.; breadth 22 millim. ( 2.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
One female example. JZ. nitida is intermediate between L. viridipennis and L. enei- 
pennis, but abundantly distinct from either; from the former it is distinguished by its 
eeneous thorax, deeper elytral strie, shorter form, &c., and from the latter by its bright 
geneous upper surface, flat elytral interstices, &c. 
** Upper surface brownish-black, the elytra more or less eneous ; form oblong. 
39. Lobopoda viridipennis. (Tab. XVIII. fige. 10, 10a, ¢.) 
Moderately elongate, rather broad and convex, brownish-black, the elytra golden-green, shining, glabrous. 
Head finely and remotely punctured; eyes large and subapproximate in the male, somewhat widely sepa- 
rated in the female; prothorax convex, the sides sinuate behind, the hind angles obtusely rectangular, 
the disc very shallowly transversely impressed in the middle before the base, the surface exceedingly 
finely and somewhat remotely punctured ; elytra rather broad, gradually narrowing from a little below 
the base, with very fine lightly impressed striz, the striz with fine oblong impressions which (like the 
strise) become still finer towards the apex, the interstices broad and flat throughout and each with a row of 
exceedingly minute punctures down the middle ; beneath brownish-black, almost impunctate, the middle of 
the metasternum and the fifth ventral segment only with a few fine scattered punctures, the metasternum 
longitudinally grooved in the centre; legs sparsely pilose, brownish-black, the tarsi lighter; antenne 
piceous or fusco-ferruginous,
