swollen ; eyes globular, entire ; antennae scarcely longer than half 

 the body, basal two joints thickened, third and fourth short, 

 equal, rest moniliform. Thorax transverse, convex, sides angulate 

 at middle. Femora fusiform, unarmed ; tibiae straight, intermediate 

 and posterior tibiae strongly emarginate at apex, the emargination 

 densely pubescent ; claws appendiculate. Prosternum subquadrate, 

 base truncate. 



Differs from Cattisina in the structure of the antennae and 

 in the unarmed femora. Except in the angulate sides of the 

 thorax this genus does not seem to differ from Nodina. 



647. Edistus cseruleus, sp. n. 



Dark blue ; basal joints of antennae fulvous ; apical joints, 

 underside and legs black. 



Ovately rounded. Head closely and finely punctured ; clypeus 

 not separated from the face, more strongly punctured than the 

 head, anterior margin concave ; eyes with distinct sulcus above ; 

 antennae very short, basal three joints fulvous, basal joint above and 

 the others black, first joint strongly incrassate, second rather longer 

 than the third, fourth and fifth equal, following joints triangularly 

 thickened, scarcely longer than broad, last elongate-ovate. Thorax 

 more than half as broad again as long, sides nearly straight, 

 anterior portion of disc deflexed, median lobe of posterior margin 

 broadly rounded and produced ; surface crowded with large, 

 deep punctures, evenly distributed. Scutellum ovate, black. 

 Elytra convex, not depressed below base, very strongly punctate- 

 striate, shoulders prominent. Posterior tibiae feebly emarginate 

 at apex ; claws appendiculate. Prosternnm quadrate, strongly 

 punctured ; anterior margin of thoracic episternum nearly 

 straight.

648. Edistus indicus, Jac. Ann. Soc. Ent. Bely. xlvii, 1903, p. 99. 



Beneath black, above metallic blue or aeneous ; base of antennae, 

 apex of tibiae and the tarsi fulvous. 



Bounded and convex. Head distinctly but remotely punctured on 

 its anterior portion ; clypeus not separated from the face ; labrum 

 obscure fulvous ; antennae short, black, basal five joints fulvous, 

 terminal seven short, thick and moniliform, second to fourth nearly 

 equal. Thorax strongly transverse, sides rounded, anterior portion 

 deflexed, basal margin produced at the middle into a short, 

 broadly rounded lobe ; surface evenly but not closely punctured, 

 the puncturation somewhat finer and closer at the sides. Scutellum 

 subovate, impunctate. Elytra convex, not depressed below base,
