296 HETEROMERA. 
Four examples. This species is perhaps nearest allied to 7. eximia, from which it 
will be known by the head being rather longer and not so deeply excavate in front ; 
the antenne longer; the thorax flatter, less narrowed and straighter at the sides 
anteriorly; the elytra with the interstices flatter, and the rows of impressions much 
finer and more lightly impressed on the disc; and the upper surface not nearly so vividly 
coloured. 
Section B. Anterior angles of the prothorax less prominent (rarely rounded) ; upper 
surface varying from dull dark bronze to bright metallic bronzy-green. Species 
winged. 
1. Upper surface dull, scarcely shining ; prothoraxz narrowly margined ; anterior tarsi 
with the three basal joints rather broad, about equal in width, and sometimes a little 
widened in the male. 
a. Epipleure extending almost uninterruptedly to the apex of the elytra. 
15. Tarpela atra. (Tab. XIII. fig. 3.) 
Tarpela atra, Allard, Rév. Hélopides, L’Abeille, xiv. pp. 7 & 46+; Mittheil. der schweiz. ent. Ges. 
v. pp. 56 & 237%. . 
Hab. Mexico (coll. F. Bates 1), Puebla (Sallé 1), Matamoros Izucar, Sayula in Jalisco 
(Hoge). 
The two examples from Sayula differ from the numerous specimens of 7. atra before 
me in having the elytra a little shorter, and with the rows of impressions rather coarser 
on the disc; I do not think they represent more than a local variety of that insect. 
V 16. Tarpela jalapensis. 
Elongate ovate, subparallel, bronze or greenish-bronze, rather dull, sometimes a little shining. Head rather 
long, closely and confluently and somewhat coarsely punctured, shallowly transversely impressed in front 
and also feebly impressed between the eyes; prothorax subquadrate, rather convex, very feebly margined, 
transverse or nearly as long as broad, the sides rounded at the middle, narrowing and sinuate behind and 
less distinctly so anteriorly, the anterior angles somewhat produced and a little prominent, the apex feebly 
emarginate, the hind angles subrectangular or subacute, the base feebly bisinuate (almost straight), the 
basal foveze very shallow or obsolete, the surface very closely, equally, and rather coarsely punctured (the 
punctures separate one from another); elytra much wider than the prothorax, subparallel, subtruncate at 
the base, the hameri rounded, with rows of elongate moderately coarse impressions, the impressions more 
or less confluent (thus forming striae), the interstices flat, very distinctly but sparingly punctured, and with 
traces of shallow transverse wrinkles ; legs (including the femora) very closely and coarsely punctured, 
pubescent; beneath closely and somewhat coarsely punctured, the ventral surface and the metasternum in 
the middle more sparingly so, the former also longitudinally wrinkled, the flanks of the prothorax more 
coarsely and confiuently punctured ; mesosternum feebly excavate ; prosternum strongly declivous behind 
the apex armed with a short erect conical tubercle; epipleurse extending to the apex of the elytra. 
Length 83-12 millim. ; breadth 33-44 millim. (3 Q.)
