Mr. W. F. Khhy— Notes on Blattlcla3. 407 



large irregular pale yellow blotch on the inner margin ; just 

 before the curve of the furrow is a small black dash beneath 

 it ; the right tegmen almost bisected hy an oblique brown 

 line running towards the tip, which it does not reach ; within 

 this the tegmen is chestnut like the other, but outside it is 

 subhyaline, darkest towards the line, and the cross-nervures 

 towards tlie margin narrowly bordered on each side with 

 white; the narrow anal furrow on crossing the transverse 

 line is lost in a large triangular hyaline spot on the inner 

 margin. Wings brownish hyaline, darkest towards the tips, 

 the costa clouded with brown and rust-colour beyond the 

 middle ; most of the transverse nervures narrowly bordered 

 with whitish. Supra-anal plate rounded, slightly incised in 

 the middle; cerci rather long, moniliform, 



Saussure's description relates to the female only ; and I 

 have nothing to add to it. His specimen was from Singa- 

 pore ; the Museum possesses both sexes from Selangor, and 

 also two specimens of allied species from East and West 

 Africa, which I no not care to describe without a longer 

 series.
