﻿1870.] 273 



without any metallic lustre ; head and prothorax punctured, tho punctures larger 

 and closer on the latter ; epistoma separated from the front by a well-marked lunate 

 impression : prothorax sab-quadrate, but little convex, a little wider than long, sides 

 narrowed anteriorly, the fore angles very strongly produced and pointed, very 

 slightly rounded at the sides — which are not margined, the edges neither reflexed nor 

 thickened, but strongly crenulated ; base strongly bisinuate, the angles obliquely — 

 or outwardly — produced, overlapping the humeral angles of the elytra ; two fovese, 

 one at each side the middle, near the base, connected by a rather broad, trans- 

 verse, slightly outwardly curved impression : scutellum smooth : elytra but little 

 wider than the prothorax at the base, but little convex, sub-parallel, or very 

 gradually widened to three-fourths their length, thence narrowed to the apex ; each 

 with nine rows of well-marked, oblong punctures, the intervals — except at the apex, 

 where they are a little transversely wrinkled, flat and smooth ; under-side and legs 

 reddish brown ; sterna and abdomen strongly and closely punctured ; tibiae finely 

 and densely punctured : antennas blackish-brown. 



Hab. Nicaragua (Chontales) ; discovered by Mr. E. Janson, Jun. 

 I dedicate this species to Edwin Brown, Esq., of Burton -on-Trent. 



TARPELA OBLONGOPUNCTATA, n. sp. 



Length 3 lines. — Head and prothorax brown, slightly bronzed, closely and 

 evenly punctured, the punctures well marked : prothorax a little convex, base mo- 

 derately bisinuate and somewhat strongly margined, hind angles not quite so produced 

 as in the preceding species : elytra shining green with purplish-coppery reflections, 

 and with a brilliant, purplish-coppery stripe down by the suture ; somewhat convex 

 and a little more expanded at the sides than in T. Brownii ; each with nine rows of 

 oblong punctures, which become much stronger and less approximate at the sides ; 

 intervals finely punctured, nearly flat on the middle, transversely irregular, or reticu- 

 lately wrinkled at the sides and apex ; the 3rd and 7th intervals, for a short distance 

 before their junction near the apex, are somewhat abruptly elevated, forming two 

 short costse, which converge to a point behind, at their junction : under-side reddish- 

 brown, punctured, the abdomen being also finely longitudinally wrinkled ; legs, 

 palpi, &c, a little paler; tibiaa densely punctured; two last joints of the antennas 

 blackish -brown. 



Hab. Mexico. 



The present species forms part of the collection Laferte. 



Elomosda, n. g. 



Mentum flat, subquadrate, transverse, angles rounded, very deeply and broadly 

 emarginate anteriorly,* leaving the labium entirely exposed : the latter prominent, 

 transversely cordiform : labial palpi moderately separated at base ; last joint a little 

 elongate, sub-cylindrical, the apex broadly truncated : inner lobe of maxillce un- 

 armed : last joint of maxillary palpi somewhat broadly securiform : mandibles 

 broadly truncated at the extremity; labrum prominent, faintly sinuous in front, 



* Or, perhaps, It would be bettor to say, the anterior half membjanaceous. — F. B.
