Mr. W. F. Kiiby — Notes on BlattidjB. 405 



rich tawny in front, the centre filled up with a large black 

 figure, with irregular front and side borders, and slightly 

 narrower below, where it unites with a deep black terminal 

 band, which extends sliglitly upwards on the sides nearly to the 

 middle; one or two indistinct tawny spots in the black figure; 

 tegmina light tawny, broadly varied with darker, with the 

 usual black basal line extending to two fifths of the length ; 

 abdomen above apparently tawny, with a broad black sub- 

 marginal band on each side ; underside generally tawny, 

 abdomen with a festooned moderately broad submarginal black 

 band on each side, meeting at the extremity. 



Hah. ? {Distant). 



Allied to B. Sulzerii, Guer. Guerin's description does not 

 agree with Sulzer''s figure of B. surinamensis, which is bad, 

 and probably represents another species. B. postica, Eiichs. 

 ( = tho7\icica, Sauss.), belongs to the same group. 



CoSTDIIN^. 



Genus CoRYDiA, Serv. 

 Corydia tonkinensis, sp. n. 



Long. Corp. cum tegm. 18 raillira. ; lat. tegm. 11 millim. 



Female, — Closely punctured, pubescent; pronotum trans- 

 versely oval, broadest at about two thirds of its length ; 

 pronotum and tegmina dark metallic green or blue, sometimes 

 with purplish reflections on the hinder half of the tegmina ; 

 tegmina crossed beyond the middle by a fulvous band, ex- 

 panded on the costa, and projecting towards the base in the 

 middle, and on the inner margin ; abdomen beneath violet- 

 black, with the three subterminal segments tawny ; antennae 

 black, slender, hardly moniliform, with about seven of the 

 middle segments pale yellow. 



Hah. Tonkin {Fruhstorfer) . 



Described from two specimens. This and the two follow- 

 ing species appear to be somewhat intermediate between 

 Corydia and IJyscologamia. 



Corydia purpuralis, sp. n. 



Male. — Allied to the last species, but rather longer and 

 narrower. Pronotum and tegmina deep metallic greenish 

 black, the costa shading into rich purple ; tegmina with a 

 large oval fulvous blotch on the costa beyond the middle, 

 and a rather darker transverse band on the inner margin 

 opposite extending half across the wing, beyond this the
