63. TiNGRA MYLOTHRINA, Sp. U. 



Looks like a small Mylothris, but is allied to T. abraxas. White, 

 slightly opaline and tinted with sulphur-yellow ; base of wings 

 orange ; primaries with the base of costa blackish-speckled ; a broad 

 apical patch commencing at external third of costal margin and 

 terminating below third median branch, but continued as a tapering 

 border by two decreasing oval marginal spots, greyish brown ; fringe 

 spotted between all the nervures with white ; secondaries with five 

 large and one small marginal brown spots : wings below white, 

 orange at base, primaries with nine marginal spots commencing from 

 the second subcostal branch ; secondaries with six marginal spots. 

 Expanse of wings 39 millim. 



Monbuttu. 



Only one example of this very distinct species was obtained, its 

 body is somewhat injured, but it appears to be normal in colouring.

Stazione Bauri, September 1883. 



As elsewhere stated, P. undularis was originally named by Bois- 

 duval, entered as Pentila undularis by Doubleday in his Museum 

 Litt, and was stated to be the type of the genus by Westwood (who 

 first characterized Pentila). There can be no doubt whatever that 



^ To give the lettering of a plate more authority than the test which corrects 

 it Beems to me utterly ridiculous ; the lettering of a plate may be tampered 

 with by a lithogi-aphic writer, and if an author has no power to point out the 

 error, he may be quoted as the originator of the most absurd nonsense-name.
