480 Mr. F. Bates's descriptions of 



tibife finely denticulate at outer celije, the outer apical augle 

 strongly dentiform: intermediate tarsi feebly dilated, the joints 

 longer than broad: epipleural fold continued to the apex of elytra. 



Chianalus costipennis, n. sp. 



$ Oblong-ovate, dark browu ; head rather strongly and closely 

 punctured; prothorax transverse, feebly convex, wider at base 

 than apex, sides well rounded, a little uneven, margins narrowly 

 depressed; finely punctured, foveate at each side of the disc, and 

 a depression at each side at the base; the angles obtuse: elytra 

 oval, suture costiform, and on each elytron fom- stout costa?, 2-3 

 united before the apex and continued as but one ; the intervals 

 also each with a fainter costa ; finely granulose-punctate, rugulose 

 and hispid. 



$ All the costaj on elytra sui)et[ual. Length $ o^ lines ; 

 ? 5^-6 lines.

MYATis, n. gen. {Platyscdides). 



Head very short and transverse, epistoma truncated nearly 

 level with base of antenna: prothorax variable, usually curvedly 

 narrowed in front, subparallel behind ; front angles obtuse, hind 

 angles acute: elytra oblong, gently convex, shovdders more or 

 less oblique, humeral angle prominent, sometimes dentiform; 

 sides feebly rounded, narrowed and gently declivous behind ; a 

 little hispid at the apex and sides: intermediate tarsi scarcely 

 at aU dilated: intermediate tibia^ in $ thickened behind and, 

 as well as the hind tibia', densely fringed within with silky 

 golden yellow hairs, the pro- and meso-sterna are not nearly i-o 

 convex, or bulged out, as in the other genera of the grou^^: the 

 epipleural fold does not reach the apex of elytra. 



Jifi/dtis /mmeridis, n. sp.' 



Oblong, pitchy-brown, head and prothorax nitid: hear! finely 

 punctured, pubescent at sides and behind: epistoma squarely 

 truncated in front and ciliated: prothorax gently convex, nearly 

 as long as bi'oad, finely uniformly punctured, narrowed in front, 

 shghtly incurved behind, hind angles ])rominent, subacute, out- 

 wardly directed: elytra a little expanded to behind the middle,
