310 HETEROMERA. 
longitudinally wrinkled and minutely punctured in the middle, the sides of the metasternum and side-pieces: 
with scattered shallow coarsish impressions, the flanks of the prothorax, very finely and shallowly strigose ;. 
prosternum strongly declivous, the apex unarmed ; mesosternum declivous, feebly excavate. 
Length 10 millim.; breadth 4 millim. (<¢.) 
Hab. Mexico, Juquila (Sal/é). 
One example. This species is remarkable on account of the very long and slender 
legs and antenne (the latter with very long apical joint, in the male), the expanded. 
sides of the thorax, the closely punctured fine elytral stria, subparallel depressed form, 
&c.; it approaches 7. silvicola. 
39. Tarpela suturalis. 
Oblong ovate, rather convex, subparallel, very shining, colour variable—more or less metallic bronze-green, with 
cupreous and golden reflections. Head broad, somewhat coarsely and not very closely punctured, the: 
vertex smoother, bronzy-green, the anterior half and the intraocular space golden, the epistoma rather 
long, truncate in front, and limited behind by a very shallow groove; antenne long, reaching to the 
middle of the elytra in the male, joints 8-10 long and narrow, ferruginous; prothorax strongly trans- 
verse, rather convex, strongly margined, the margins a little expanded and somewhat broadly grooved 
within, the sides rounded at the middle, narrowing and rather strongly sinuate behind, and obliquely 
converging in front, the apex rather deeply emarginate, the anterior angles broadly rounded and. 
prominent, the base bisinuate and very distinctly margined, the basal fovez shallow, the hind angles 
subrectangular, the disc with a shallow transverse sinuous impression before the base, the surface 
sparingly and finely punctured (in one example much smoother), colour—in one example golden-green, 
with the sides and a narrow longitudinal space on the disc cupreous, in the other light bronzy-cupreous,. 
with a narrow line on the disc, and the base and apex more or less tinged with golden or green; elytra 
moderately long, rather convex, subparallel, rather deeply punctate-striate, the punctures elongate and 
distantly placed towards the sides, and finer and shallower on the disc and at the apex, the interstices slightly 
convex, flatter on the disc, and almost impunctate, colour metallic green, the sides, the base narrowly, the 
suture, and a narrow oblique stripe from the shoulder to the apex, golden-cupreous ; legs dark ferruginous, 
the femora darker; anterior tarsi in the male with the three basal joints a little dilated, but distinctly 
decreasing in width outwardly ; beneath brownish-bronze, with a slight golden tint, shining, very sparingly 
and finely punctured, the ventral segments 1-3 much more distinctly so, and also longitudinally wrinkled, 
and similar in both sexes, the flanks of the prothorax rather coarsely strigose; prosternum declivous, the 
apex produced and a little raised; mesosternum moderately excavate. 
Length 9 millim.; breadth 4-43 millim. (¢ @.) 
Hab. Guaremaia, El Tumbador (Champion). 
Two examples. This insect is allied to 7’ stlvicola; the thorax, however, is broader, 
and more distinctly sinuate at the sides behind the middle; the elytra shorter, less. 
parallel, more deeply striate, the strie more coarsely punctured towards the sides, the 
interstices slightly convex; the prosternum differently formed, &c. In the structure of 
the anterior tarsi, and the sculpture of the ventral surface, the male agrees with the 
same sex of 7. silvicola.
