base rectilinear. The punctuation strong and sharp ; the 

 punctures in the discoidal impression (which is very shallow 

 and ill-definedi 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 

 costae blackish. There are four smooth costse, the first 

 abbreviated before the middle, the second and third well 

 marked, the fourth fine and abbreviated at the base and 

 apex. The double lines of fovese between the suture and the 

 second costa and the second and third costae are regular and 

 the fovese are subquadrate. The fovese 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 underside is clotlied with fine grey pubescence. The 

 abdomen is veiy distinctly and rather closely punctured. 

 There is an oval, brown, pubescent s})ot on the basal segment. 



Long. 14 ram. 



Hab. 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. 



Polycesta Gossei, sp. n. 



Elongate-oblong, much flattened, green ; elytra ferru- 

 ginous, shaded with green at the suture. Thorax at 

 the widest scarcely wider than the elytra, only slightly 

 angular at the sides, obliquely narrowed in front, very 

 slightly narrowed posteriorly ; green, shaded with purple- 

 coppery at the base. Disk lightly impressed; the punctures 

 rather coarse, very close, and rather confused, rather smaller 

 at the sides, with two spots at the base which have only a 

 few punctures. Elytra subparallel, with a not very distinct 

 costa near the scutellum extending about a quarter the 

 length of the elytra. There are two other very distinct 

 smooth costse. The foveas which form the double lines are 

 very regular and somewhat round. Beyond the second 

 complete costa there are four rows of regular somewhat 

 round foveae or large punctures. The underside is a beautiful 

 bluish green, the legs, parts of the sterna, and margins of the 

 segments shaded with purple. Tarsi cyaneous. The abdo- 

 men has some fine greyish pubescence, and on the basal 

 segment there is a brown velvety spot. 



Long. 11 mm. 



Hab. Jamaica [Gosse).
