294 HETEROMERA. 
intraocular space still more coarsely and confluently punctured ; antennz rather more slender towards the 
base than in 7’. thoraciea; prothorax much as in TZ’ thoracica, but with the entire surface still more 
coarsely and closely punctured, the punctures exceedingly coarse and obliquely or longitudinally confluent ; 
elytra rather more parallel (at least in the male) than in 7’. thoracica, with regular rows of coarse deep 
longitudinal closely placed impressions from the base to the apex, the interstices about as wide as or 
scarcely wider than the rows of impressions (the sutural interstice from the end of the sutural row much 
the broadest), regularly and strongly convex throughout, and almost smooth, the humeri prominent in 
front ; femora very coarsely and rather closely punctured, the tibie still more closely and roughly so ; 
beneath golden-bronze, more shining, exceedingly coarsely punctured, the middle of the metasternum 
smoother, the punctures on the sides and ventral surface more or less longitudinally confluent, the flanks 
of the prothorax very coarsely strigose; mesosternum horizontal, V-shaped, deeply excavate within, its 
raised sides vertical in front; prosternum horizontal, strongly acuminately produced. 
Length 7-8; millim.; breadth 33-4 millim. (¢ @.) 
flab. Mexico, Acapulco (fHége). 
Six examples. This species will be readily identified by the peculiar sculpture of the 
elytra, the exceedingly coarsely punctured thorax and under surface, and the sparingly 
pilose surface. 
11. Tarpela foveipennis. (Tab. XII. fig. 26.) 
Elongate ovate, moderately convex, subparallel, brownish-bronze, with a slight greenish tint, not very shining. 
Head very broadly transversely impressed in front, and with a shallow rounded impression between the 
eyes, very coarsely, closely, and subequally punctured, clothed with short scattered decumbent hairs, the 
labrum densely fringed with fulvous hair; antenna rather short, piceous ; prothorax very uneven, trans- 
verse, widest about the middle, the sides sinuate and a little narrowed before the base, slightly rounded, 
and about equally narrowing anteriorly, and rather strongly margined, the margins coarsely crenulate 
before the middle, the anterior angles broadly and strongly produced and rounded, the apex with the 
central part almost straight and slightly raised, the posterior angles subrectangular, the base strongly 
bisinuate and very distinctly margined, the basal foveee broad and deep, the disc with traces of a smooth 
impressed central line and with a shallow rounded impression on each side above (and within) the fover, 
the surface subequally punctured like the head but rather more coarsely so, the punctures mostly separate 
one from another, of a greener tint than the head or elytra; elytra wider than the prothorax, iong, sub- 
parallel, the humeri a little prominent, with rows of very coarse deep longitudinal impressions, the 
impressions shorter, finer, and much more closely placed on the basal fifth, if anything finer outwardly, 
and at the sides and apex placed in large shallow excavations, the interstices sparingly but very distinctly 
punctured, rather irregular, somewhat raised, and here and there transversely confluent towards the sides _ 
and apex, the third, fifth, and seventh sinuously costate behind, of a brownish-bronze tint ; legs coarsely, 
the tibie very roughly and confluently, punctured, clothed with short decumbent hair, the inner sides of 
the tibiae and the femora beneath with longer hair; beneath greenish-bronze, shining, very coarsely 
punctured, the flanks of the prothorax very coarsely strigose ; mesosternum subhorizontal, V-shaped, 
moderately deeply excavate within, its raised sides subvertical in front though rounded off above; pro- 
sternum horizontal, strongly acuminately produced. 
Length 123 millim. ; breadth 54 millim. 
Hab. Mexico, Chiapas (Sallé). 
One example. This species is closely allied to, and of the size of, 7. thoracica; it 
differs, however, in the head being less deeply impressed in front, and more equally 
punctured ; the thorax more rounded at the sides and rather strongly sinuate before the 
base, with the anterior angles less produced, and the surface more equally punctured ; 
the legs more pubescent and more coarsely punctured; the mesosternum a little rounded
