the middle finely and closely strigose. Pygidium and the apical 

 dorsal segment of the abdomen finely and closely strigose, the former 

 very prominent and feebly bi-nodose at the apex. Underside coarsely 

 but rather sparsely punctured on the meta-coxae and sides of the 

 metastemum ; mesosternal process gradually narrowed to the apex 

 where it is acute. Legs closely strigose on the femora and outer 

 side of the tibiae, anterior tibia with the two marginal teeth and the 

 produced apex very acute. Length 33 mm., breadth 15 mm. 



Khasia Hills, Assam (Type in coll. Jans on). 



The strongly raised margins of the apical lobes of the 

 clypeus form a semicircular rim to a pit-like cavity on 

 either side, and coalesce with the narrow median carina 

 at the base of the excision : this peculiarity and the strongly 

 punctured and non-sulcate prothorax and closely strigose 

 legs will suffice to at once distinguish C. arroivi from all 

 the hitherto described members of the genus. In general 

 aspect it most nearly resembles narrow examples of C. 

 budda, G. P., that are without the usual yellow markings 

 on the upperside. 



Pseudochalcothea ritsemae, n. sp. 



Body of a narrow oval form and deeply channelled along the 

 median line of the upperside. Dark grass-green, shining; the 

 sides and sutiu:e of the elytra with a reddish tinge in some lights; 

 head, sides of the prothorax and underside golden green ; antennae, 

 palpi, tibiae and tarsi fulvous tinged in parts with green and coppery 

 red. Head sparsely punctured, convex and smooth in the middle ; 

 clypeus a little widened in front, margined at the sides and deeply 

 notched at the apex. Prothorax strongly narrowed in front, the 

 sides sinuous and slightly emarginate at the basal half, the basal 

 angles produced and sub-acute, smooth on the disc, punctured and 

 strigose at the sides. Scutellum punctured at the base only. 

 Elytra gradually narrowed posteriorly, separately rounded at the 

 apex, the sutural angles a little produced and acute, some scattered 

 fine punctures in the sutural depression and a regular row next the 

 suture, at the sides four or five rather confused rows of punc- 

 tures on the basal half and thence irregularly strigose to the apex. 

 Pygidium prominent and closely strigose, deeply grooved and bi- 

 nodose at the apex. Underside of the body almost impunctate; 

 sternal process broad at the base and obliquely narrowed to a point 

 at the apex ; abdomen concave in the centre and broadly emarginate 

 at the apex. Front tibiae slender, curved and without marginal 

 teeth ; hind tibiae on the inner side with a broad, thin and flattened
