Head, pronotum, body beneath, and legs dark purplish 

 brown ; tegmina pale shining ochraceous, extreme base and 

 costal area dark purplish brown, apical area more or less 

 tinged with castaneous ; pronotum very coarsely punctate, 

 finely, centrally, longitudinally carinate, posterior process 

 tricariuate, only slijilitly elevated above scutellum, and then 

 continuously impinging on inner m.argiu of tegmina to a 

 little before tegminal apex, disk of pronotum crescented in 

 form, the lateral processes broad and prominently directed 

 backward ly, in a line with the lateral pronotal margins. 



Long, 10 mm. ; exp. lat pi'onot. process. 6 mm. 



Hah. Siam ; Chantaboun {M. H. Mouhot). 



Dacaratha, gen. nov. 



Allied to Emphusis, Buckt., but pronotum less regularly 

 crescented in form, its frontal area shorter and strongly 

 centrally carinate, the posterior process undulate and dis- 

 tinctly elevated above scutellum, the apical area upwardly 

 directed beyond the posterior angle of the tegminal inner 

 margin, the anterior lateral processes much more angulately 

 and less crescently produced. 



Type, D. nyasana, Dist. 



Emphusis appears to be confined to the Oriental and 

 Malayan regions y Dacaratha at present is only known from 

 Central Africa.

 femora black, tibiae and tarsi dark castaneous ; anterior and 

 lateral areas of sternum greyishly pubescent ; tegmina sub- 

 hyaline, wrinkled, base black, outwardly obscurely margined 

 with dull ochraceous, apical area more or less bright testa- 

 ceous ; pronotum thickly, finely punctate, centrally longitu- 

 dinally carinate, the posterior process tricariuate, convexly 

 raised above scutellum and then impinging on the posterior 

 angle of the inner tegminal margin, and beyond this it 

 straightly continues for a short distance, the lateral pronotal 

 processes short, moderately obliquely angularly directed 

 backwardly. 



Long., inch tegm., 8 mm. ; exp. lat. pronot. process. 4 mm.
