TARPELA. 293 
b. Prosternum horizontal, strongly acuminately produced ; mesosternum more or less 
horizontal, its raised sides vertical in front, deeply excavate. Species winged. 
8. Tarpela thoracica. (Tab. XII. fig. 24.) 
Oblong ovate, subparallel, moderately convex, brownish-eneous, with a slight golden tint, moderately shining. 
Head slightly pilose, very coarsely and somewhat closely punctured, the intraocular space exceedingly 
coarsely so and the punctures here longitudinally or obliquely confluent, the usual transverse depression 
very broad and deep and extending backwards to beyond the eyes and there ending in a rounded impres- 
sion; eyes oblique, narrow, convex; antenne rather stout, ferruginous, the four outer joints darker and 
a little wider ; prothorax very uneven, though a little flattened, transverse, broad, as wide anteriorly as at 
the base, the sides very feebly sinuate behind the middle, slightly narrowing and rounded just before the 
apex, and irregularly and coarsely crenulate in their apical half, the anterior angles very strongly and 
broadly produced (extending as far as the front of the eyes) in front and narrowly rounded, the apex 
very deeply emarginate and with the central third almost straight and somewhat raised, the hind angles 
subrectangular, the base very strongly bisinuate, the basal fovese broad and deep, the disc longitudinally 
impressed in the middle (more distinctly so towards the base), the surface punctured (the disc usually 
rather more sparingly) like the middle of the head; elytra wider than the prothorax, a little flattened 
on the disc, with rows of very coarse deep longitudinal not very closely placed impressions, the impressions 
towards the sides slightly coarser and there placed in larger and shallower excavations, the interstices very 
evidently though sparingly punctured, rather irregular and here and there transversely connected one with 
another, slightly convex outwardly, and the third, fifth, and seventh sinuously costate towards the apex, the 
humeri prominent in front; legs coarsely punctured, the tibiae still more closely and roughly so; beneath 
of a golden-brassy tint, more or less tinged with green, shining, very coarsely but not closely punctured, 
the middle of the metasternum much smoother, the flanks of the prothorax very coarsely strigose ; meso- 
sternum horizontal, V-shaped, deeply excavate within, its raised sides vertical in front ; prosternum hori- 
zontal, strongly acuminately produced. 
Length 73-92 millim.; breadth 33-5 millim. ( ¢ 9.) 
Hab. Nicaraaua, Chontales (Belt). 
Six examples. ‘This species, though differing greatly in the structure of the pro- 
sternum, is evidently allied to 7. browni. 
9. Tarpela reticulata. 
Allied to 7. thoracica and differing as follows :—The entire surface sparsely but distinctly pubescent ; the pro- 
thorax broader, more widened anteriorly, the sides more distinctly sinuate behind the middle and more 
coarsely crenulate in front, the anterior angles exceedingly prominent, the surface very coarsely and 
rugosely punctured ; the scutellum larger; the elytra longer and more parallel, more abruptly narrowed at 
the shoulders (somewhat as in 7’. costata), the humeri rounded off and not prominent in front (the base in 
consequence straighter), with rows of very coarse and deep longitudinal impressions from the base to the 
apex, the impressions still coarser towards the sides, the interstices very irregular and almost smooth, the 
third, fifth, and seventh costate (the impressions thus forming double rows, the interspaces being trans- 
versely connected one with another), the surface clothed with scattered suberect hairs; the under surface 
very coarsely punctured, the flanks of the prothorax very coarsely strigose ; the rest as in 7’. thoracia. 
Length 11 millim.; breadth 53 millim. (¢?) 
Hab. Honpuras (Dyson, in Mus. Brit.). 
A single example of this distinct species is contained in the National collection. 
10. Tarpela costata. (Tab. XII. fig. 25.) 
Oblong ovate, subparallel, moderately convex, brownish-eneous, with a slight golden tint, rather dull, slightly 
pubescent, the elytra clothed with short scattered suberect hairs. Head as in 7. thoracica, but with the
