ART. 9 WEST INDIAN BUPRESTIDAE FISHER 15 



nous. Thorax not quite twice as broad as long, black, dull, broadest behind 

 the middle, strongly angular at the sides, obliquely narrowed in front and 

 behind ; the space from the lateral angle to the base rectilinear. The punctua- 

 tion strong and sharp; the punctures in the diseoidal impression (which is 

 very shallow and ill defined) moderately large and very slightly separated, 

 at the sides they are smaller and crowded together. There are two small 

 spaces at the base which have only a few punctures. The elytra are rusty 

 brown, the margin and eostae blackish. There are four smooth costae, the 

 first abbreviated before the middle, the second and third well marked, the 

 fourth fine and abbreviated at the base and apex. The doui)le lines of foveae 

 between the suture and second costa and the second and third costae are 

 regular and the foveae are subquadrate. The foveae which form the more 

 lateral lines are regular, but a little less quadrate. Viewed beneath, the 

 lateral ridge of the thorax is very sharp. The whole under side is clothed 

 with a fine, gre.v pubescene. The abdomen is verj- distinctly and rather 

 closely punctured. There is an oval, brown, pubescent spot on the basal 

 segment. Long. 14 mm. EaJ). St. Domingo (or possibly Dominica). 



This species is very close to P. Chevrolati, but is smaller, and the lines 

 of punctures on the elytra are very regular. 



A single specimen from an old collection, with the locality indistinctly 

 written. 



The type of this species is in the British Museum, and since I 

 have heen unable to examine it, the species is given its position in 

 the key solely from the characters given in the original description. 



POLYCESTA CHEVROLATI Thomson 



Polycesta chevrolatii Thomson, Typ. Bupr., 1878, pp. 43. — Keeremann, Mon. 

 Bupr., vol. 1, 1906, pp. 4SS-489. 



The following is a translation of Thomson's original description : 

 Polycesta chevrolatii (Guerin Mss.) Thomson. — Habitat: Cuba. 

 Length, 21-26 mm. ; width, 81/^-11 mm. Form of P. thomae Chev- 

 rolat, but entirely black. Head granulate-punctate. Prothorax with 

 the sides strongly dilated behind the middle, feebly depressed at 

 middle, with a feeble longitudinal line at the base; surface punctate, 

 the punctures coarse and densely placed at the middle and sides. 

 Elytra carinate-fossulate, the fossae densely placed and generally 

 subelongate; sides toward the apex denticulate, with apex bispinose. 

 Body beneath and legs sparsely punctate. 



Allied to P. thomae Chevrolat, but differs from it: first by the 

 general appearance (livree) ; second, by the prothorax being straight 

 anteriorly and not as strongly punctured ; third, by the fossae on the 

 elytra generally elongate, and finally by the underside less densely 

 punctured. 



There is a single specimen of this species in the British Museum, 

 but it has not been examined by the writer. The species was un- 

 known to Kerremans, as he simply quoted Thomson's description in 

 his Monographie des Buprestides.
