NEW PHYTOPHAGOUS COLEOPTERA. 



81 



verse band at the middle, another near the apex, and the suture 

 narrowly purplish, margined with green. Length, 9-10 mill. 



Head cupreous, remotely punctured, the vertex with a deep central 

 groove ; the spaces surrounding the eyes and the clypeus metallic 

 blue or green, the latter closely punctured ; labrum and mandibles 

 black; antennaB dark purplish, the last five joints gradually and 

 broadly dilated ; thorax about one-half broader than long, slightly 

 narrowed in front, the anterior angles produced, the surface convex, 

 strongly and remotely punctured, the sides and the base nearly im- 

 punctate, the latter portion metallic green, the anterior part cupreous, 

 or the entire surface of the former colour; scutellum purplish, im- 

 punctate ; elytra not depressed below the base, rather strongly and 

 closely punctate-striate, reddish cupreous, with a transverse purplish 

 band at the middle, which narrows greatly towards the suture with- 

 out extending to the latter ; another similarly coloured band of curved 

 shape extends across the suture near the apex, but not to the lateral 

 margins, the suture itself also narrowly purplish and margined like 

 the bands with metallic green ; below and the legs varied with purplish 

 or green ; claws appendiculate. 



Hab. Burmah and India. 



I have given here a more detailed and correct description of 

 this handsome species than Baly has done, who described the 

 head and legs as black, which certainly is not the case in the 

 type contained in the British Museum. Two other specimens I 

 received from Herr Bang-Haas. 



Chrysomela gahani, sp. nov. 



Very convex, black ; head and thorax impunctate, sides of the 

 latter with a deep longitudinal sulcus ; elytra dark fulvous, entirely 

 impunctate. Length, 9 mill. 



Head subquadrate, black, shining, impunctate ; clypeus distinctly 

 separated from the face ; antennae slender, black, the terminal joints 

 elongate, gradually thickened ; thorax more than twice as broad as 

 long, the sides straight, the anterior angles produced but blunt, the 

 anterior margin straight at the middle, the disc entirely impunctate, 

 the sides thickened, bounded within by a deep sinuate longitudinal 

 groove ; scutellum broader than long, blackish ; elytra very strongly 

 convex at the middle, dark fulvous, impunctate ; under side and legs 

 black, shining, impunctate ; prosternum narrowly elongate. 



Hab. Ceylon. 



This species, of which I possess a single example, will not be 

 difficult to recognise on account of the entirely impunctate upper 

 and under surface, a rare instance in species of this genus. 



Haltica semipiceus, sp. nov. 



Below and the legs piceous ; above dark blue ; basal joints of the 

 antennae fiavous ; thorax very finely punctured, the sulcus obsolete ; 

 elytra very closely and distinctly punctured. Length, 3 mill. 



Head impunctate at the vertex, the frontal elevations narrowly 

 transverse, interrupted at the middle by another transverse groove ;
