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 Callisina 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 Noclina. 
647. Edistus casruleus, 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 hroad, 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. Prosternum 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. 
Hounded and convex. Head distinctly but remotely punctured on 
its anterior portion ; clypeus not separated from the face : labrurn 
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,
