double rows with two distinct longitudinal costae that extend from 

 the shoulders downwards to near the apex. Underside and legs 

 fulvous. Claws appendiculate. 



Length 6 mm. 



Hab. Burma : Teinzo. 



This small species, which differs much from most other species of 

 Corynodes by its peculiar colour, also varies greatly from the typical 

 forms in the apparent absence of the deep sulcation at the sides of 

 the vertex, which is present in all its congeners ; the head is how- 

 ever, in the type contracted within the thorax up to the margins of 

 the eyes, hiding therefore the vertex, which may possibly be found to 

 be sulcate, if exposed to view ; the flat lower portion of the face also 

 differs from most other forms placed in the genus. On account, 

 however, of the general typical shape and the other structural 

 characters which are present, I have retained this insect in 

 Corynodes.

Metallic blue, green or cupreous ; basal joints of antennae 

 black. 



c . Head coarsely and closely punctured, with a more or less 

 distinct central groove ; a small tubercle at base of clypeus, the 

 latter closely and finely punctured, finely pubescent ; labrum 

 black ; antennae extending to about the middle of the elytra, 

 terminal five joints broadly dilated, second joint sometimes obscure 

 fulvous. Thorax when seen from above subconical, about half as 

 broad again as long, lateral margins nearly straight, surface very 

 sparingly but deeply punctured. Elytra rather strongly punc- 

 tured in closely approximate rows which are occasionallv in pairs, 

 last interspace near the lateral margins thickened ; area below the 

 base rather feebly depressed. Claws appendiculate. 



Length 10-11 mm. 



Hab. Bengal: Calcutta. 



The strongly and remotely punctured thorax, subconical shape 

 of the latter, the strongly punctured elytra and bright metallic 

 coloration distinguish this species.

" Dark bluish-green. Head dark blue, impunctate, with a faint 

 medial longitudinal impression ; antennas very long, rufo-fuscous, 

 apical five joints broadly dilated. Thorax narrowed in front, very 

 finely and sparingly punctate. Scutellum impunctate. Elytra 

 robust, with a transverse depression on either side behind the 

 shoulders, surface finely punctate-striate. Abdomen and underside
