HETEROMERA. 553 
Tarpela jalapensis (p. 296). 
To the Mexican locality given, add :—Mescala in Guerrero (H. H. Smith). 
Five specimens. 
19 (a). Tarpela incilis. 
3. Oblong-ovate, rather broad, convex, dark bronze, slightly shining, glabrous. Head short and broad, 
densely, finely punctured; antenne black, reaching to about the basal third of the elytra, gradually 
thickening outwardly, the third joint not more than one-half longer than the fourth; prothorax 
moderately convex, broad, short, transversely subquadrate, very feebly margined at the sides, the sides 
parallel behind and slightly converging anteriorly, the base bisinuate, the apex broadly and feebly 
emarginate, the hind angles sharply rectangular, the anterior angles sharp and rather prominent, the 
entire surface very densely, finely punctate, the punctures separate one from another; elytra wider than, 
and three times as long as, the prothorax, deeply sulcate throughout, the interstices (except towards the 
suture anteriorly) scarcely wider than the sulci, strongly convex, closely, transversely notched on either 
side (these notches extending across the sulci), and with a few exceedingly minute punctures, the humeri 
obtuse but distinct; beneath greenish-eeneous, closely punctured—the punctures on the metasternum 
coarse, those on the venter much finer, the flanks of the prothorax with moderately coarse oblong impres- 
sions; the first and second ventral segments densely, finely punctate and pubescent along the middle ; 
prosternum coarsely punctured, acutely produced and slightly declivous behind, the mesosternum V-shaped, 
feebly excavate, the sides rounded off in front; epipleure abbreviated behind ; legs densely punctured ; 
anterior tarsi with the three basal joints moderately dilated. 
Length 63, breadth 3 millim. 
Hab. Mexico, Plan de Barrancas (Lohr). 
One specimen. ‘This species is perhaps best placed near T. torrida, but is not very 
closely allied to it. The elytra are deeply sulcate, with the interstices very convex, 
scarcely wider than the sulci, and transversely notched on either side. The thorax is 
short and very feebly margined, with rather prominent anterior angles. 
21 (a). Tarpela flohri. 
Modefately elongate, rather convex, subparallel, dark bronze, shining, glabrous. Head densely, moderately 
finely punctate ; antenne only reaching to about the basal fourth of the elytra in the male, shorter in the 
female, slender, gradually thickening outwardly ; prothorax moderately convex, transverse, very feebly 
margined at the sides, more distinctly so in front, about equal in width at the base and apex, widest a 
little before the middle, the sides feebly sinuous and converging anteriorly, constricted and strongly 
sinuous behind, the base bisinuate, the apex feebly emarginate (subtruncate if viewed from above), the 
hind angles acute and directed a little outwards, the anterior angles sharp but not produced in front, the 
surface very densely, moderately finely punctate, the basal foves shallow but distinct ; elytra considerably 
wider than, and about three times as long as, the prothorax, subparallel in their basal half, slightly trans- 
versely flattened immediately below the base, with rows of moderately coarse, oblong, approximate 
punctures placed in shallow strie, the strise becoming very deep towards the sides and apex, the inter- 
stices convex, flatter on the disc, almost smooth, the humeri very obtuse; beneath shining, eneous, 
closely, finely punctate, the punctures on the metasternum coarser, those on the flanks of the prothorax 
very shallow, dense, and reticulate; prosternum abruptly declivous behind, the mesosternum very feebly 
excavate ; epipleure abbreviated ; legs densely punctured, the tibizw roughly so; anterior tarsi similarly 
formed in both sexes, the basal joints narrow. 
Length 7-9, breadth 23-4 millim. (cb 2.) 
Hab. Mexico, Tlaltizapan (Flohr).
