of St. Vincent, Grenada, and the Grenadines. 29 



i&land of Trinidad by Mr. Broadway. Allied to B. neo- 

 trojncalls, Champ., from Central America, but larger and 

 differently coloured, the thorax more narrowed in front, 

 the elytral striae more finely punctured and the interstices 

 more convex. B. pertyi, Cast., from Brazil, is also an 

 allied form. On fire- wood, and also attracted to " light '* 

 (Smith). 



ACROPTERON. 



Acropieron, Perty, Del. Anim. artic. Bras., p. 64 

 (1830). 



Acropteron quadraticolle, n. sp. 



Very elongate, narrow, convex, shining, brownish-bronze. Head 

 thickly, unequally punctate, the epistoma smoother, transversely 

 grooved in front. Prothorax convex, nearly one-half broader than 

 long, completely margined at the base, the sides feebly sinuate — 

 almost straight when viewed from above ; the anterior angles 

 very prominent but rather obtuse, the hind angles acute ; the 

 surface somewhat thickly, moderately finely punctate, a narrow 

 space down the centre excepted, and feebly transversely grooved 

 in the middle before the base. Elytra about five and one-third 

 times the length of the prothorax, gradually narrowing for about 

 three-fourths of their length, and thence rapidly converging to the 

 apex, the apices sharply mucronate and divaricate ; rather coarsely 

 seriate-punctate ; the interstices smooth, almost flat on the disc, 

 convex at the sides and apex. Posterior tibias similar in both sexes. 

 Length 15-16A, breadth 2^-25 mm. ( ^ ? .) 



Hab. St. Vincent — Leeward side; Grenada — Grand 

 Etang, alt. 1,900 feet, and Balthazar, both on the Wind- 

 ward side. 



Four specimens. Allied to A. punctlcolle, Champ., 

 from Chiriqui, but differing from it in the broader and 

 sharply transversely-quadrate thorax, the sides of which 

 are almost straight, and the angles very prominent; 

 the head and thorax are also much more sparsely 

 punctured. From A. cliahrieri, Fleut. and Salle, from 

 Guadeloupe I., it may be known by the divaricate and 

 sharply mucronate apices of the elytra, and the prominent 

 anterior angles of the thorax. The posterior tibia? are 

 simple in the male. On foliage (Smith).
