in front, in punctata square or almost convex in front. It 

 will appear from these remarks that Lacordaire's description 

 of the genus (Gen. Col. ix. 2, p. 475), in which he mentions 

 " leurs crochets des tarses divariques " and their " saillie 

 mdsosternale lamelliforme, recourb^e en arri^re, ddclive et 

 obtusement tuberculeuse en avant, non contigue h la saillie 

 prosternale," is quite inapplicable, and was probably taken 

 from his own species only. For this species {simplex^ 

 Lacord., op. cit.) I propose to substitute the generic name 

 Sormida^ with characters as given by Lacordaire for the 

 genus Heteroclytomorplia.

Black, subnitid, with oval and linear spots of a pale grey 

 colour. Head with the carina of the vertex distinct enough, 

 and with a pale grey interrupted line in the channel between 

 them. Clypeus, labrum, base of mandibles, cheeks, and 

 round the eyes also pale grey. Prothorax punctured above, 

 with a pale grey vitta on each side and four spots of the same 

 colour on the disk ; the two posterior spots are at the base, 

 are short, and lie close together. Scutellum nearly semicir- 

 cular, slightly grey behind. Elytra thickly enough punc- 

 tured on the basal half, and each with about twelve very 

 distinct pale grey spots, arranged as follows : — four at the 

 base somewhat indistinctly united to each other; two, of 

 which one appears nearly double, beneath the shoulder ; three 

 oval spots at the middle, and, with the corresponding three of 

 the other elytron, forming an irregular hexagon ; then follow 

 an elongated spot, and, at the apex, two linear spots, one 

 near the suture and one near the margin, which unite poste- 

 riorly. The outer angles of the apices mucronate. The legs, 

 underside of the body, except in the middle, and basal joints 

 of the antennae covered with a slight greyish pile. 



By the colour and disposition of its spots, and by the deep 

 blackness of the parts between, this species may be distin- 

 guished from the other species of the genus.
