 Type, S. femorata, Drury, from India, China and Ceylon. 

 Range. Africa ; Madagascar ; India ; Ceylon ; China and some 

 of the Malayan Islands.

 this genus are sufficiently distinguished from the rest of the 

 Chrysomelidce by their large size, metallic colouring and peculiarly 

 formed long hind legs.

(Alurnus) Spec. Ins. i, 1781, p. 115. 

 Sagra tridentata, Weber, Obs. Ent. 1801, p. 62, <$ . 

 Sagra druryi, Lacord. Man. Phytoph. \, 1845, p. 32. 



Cupreous metallic blue or green, generally more or less green 

 on the elytra, sometimes entirely blue in specimens from India. 

 Thorax subquadrate, the anterior angles slightly produced, the 

 surface impunctate ; elytra with a more or less distinct depression 

 at the base near the suture ; shoulders prominent with a few 

 short rows of fine punctures ; rest of the disc nearly impunctate. 

 3 . With rather slender and very elongate femora to the posterior 

 pair of legs, these extend well beyond the apex of the elytra and 

 are armed with a large outer tooth near the apex with a smaller 

 one beyond it ; tibiae of the posterior legs curved at the base, with 

 a tooth near the apex on each side ; first abdominal segment more 

 or less pubescent. $ . Femora of the posterior legs not, or very 

 slightly, prolonged beyond the apex of the elytra, the apical teeth 

 on them so prominent in the d 1 replaced by a toothed ridge on 

 the underside. 



Length <5 $ 16-20 mm. 



Hob. Throughout India and China; extending to Borneo and 

 Java. 



2. Sagra longicollis, Lacord. Man. Phytoph. i, 1845, p. 35. 



Metallic greenish-blue. Antennas reach to about the middle of 

 the elytra ; thorax elongate, its anterior angles prominent ; elytra 

 deeply depressed, below the base finely coriaceous, punctate- 

 striate, the striae often obsolete. d" Femora of the posterior 

 legs elongate, the apex bidentate ; apex of tibiae mucronate, biden- 

 tate, the outer tooth large. 



Length 20-22 mm. 



Hob. " India orient." Assam (Atkinson). 



Very closely allied to S. femorata, but distinguished from that 

 and other species of the genus by the elongate thorax which is 

 about one-fourth longer than its anterior width. Lacordaire 

 described this species from two specimens contained in the Dejean
