c HALTICINiE. 



212. Paradibola nila *, sp. nov. 



Very similar to P. inclica, but larger and differing in coloration. 

 Colour pure metallic blue ; the four basal segments of the 

 antennae, the palpi, the fore and middle legs entirely, the tibiae 

 and tarsi only of the hind legs, and the abdominal sternites 

 (except part of the first) bright yellow -brown ; the seven apical 

 segments of the antennae fuscous. 



Read entirely imbedded in the prothorax ; front narrow and 

 wedge-shaped, with surface finely punctate, frontal tubercles 

 rounded, interantennal carina broad. Antennae short, passing 

 a little distance beyond the base of the pronotum, covered 

 with fine pubescence (except the two or three basal segments); 

 first segment long and club-shaped, second small and almost 

 equal to, or very slightly shorter than, third, fourth elongate; 

 from the fifth to the end the segments are almost equal. Pro- 

 thorax much broader than long, convex, and in other respects as 

 in P. indica. Scutellum triangular, with apex acute and surface 

 finely shagreened. Elytra broader than prothorax ; the whole 

 surface is very minutely rugose, and each elytron has ten or 

 eleven rows of fine punctures, the rows, at least some of them, 

 having the appearance of being placed in very faint furrows. 

 Underside : prosternum broad, elevated, with a median longitudinal 

 depression and sparsely covered with fine hairs ; abdominal 

 sternites, some parts of the hind femora, and the other parts of 

 the legs sparsely covered with fine hairs. 



Length, 5 mm. ; breadth, 3| mm. 



INilgiri Hills (G. F. Hampson). 



Type in the British Museum. Described from two examples. 



It is possible to regard this insect as a variety of P. indica, but 

 I doubt this after examining five examples of P. indica and two 

 of the present species. 



Genus ARGOPISTES, Motschuhky.

Genotype, Argopistes biplagiata, Motsch. (Amur-land). 



Body oval or round, convex. Head small, inclined in front ; 

 front with a little carina under the bases of the antennae, frontal 

 tubercles absent. Antennae closely approximated at the base, 

 extending a little distance beyond the base of the pronotum ; first 

 segment long and club-shaped, about equal to, or somewhat shorter 

 than, the following three together, third segment the shortest; 

 from the fifth the segments are gradually somewhat thickened. 

 Prothorax much broader than long, slightly narrowed in front, 

 sides sloping; no ante-basal furrow. Scidellum small, triangular,
