from eacli other, becoming rather indistinct towards the hind 

 angles. The elytra are very gradually narrowed posteriorly, 

 rather acute at the apex ; the punctures forming the lines 

 are moderately strong, rather close together, but not equi- 

 distant; the interstices are very gently convex, very finely 

 punctured, the punctures irregular and slightly separated.

This species closely resenibles G. viridipennis, SufFr., from 

 Cuba. It is, however, rather smaller than any specimens of 

 that species before me ; there is a well-marked fovea between 

 the antennge ; the thorax is moderately closely and distinctly 

 punctured, although the punctures are not sharply defined. 

 The scutellum is long and narrow, shining, brassy black. 

 The elytra are of a brassy green tint, with the posterior 

 margins and apex dirty yellowish. There are lines of strong 

 punctures, but the punctures are somewhat unequal in size, 

 larger at the base than on the disk, scarcely half the size they 

 are in C. viridipennis, and the lines are scarcely at all im- 

 pressed except at the sides and apex, and consequently the 

 interstices are scarcely convex. 



NEUEOPTERA. 



DON AT A. 



The specimens of this order were so injured by transit as to 

 be unrecognizable. The fragments, however, are evidently 

 those of one of the Libellulidse. There are also larvas of one 

 of the ^schnidse.
