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.

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 occasionally 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 ; antennae 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
