URAPTERYGID^. 



URAPTERYX, Leach. 

 Urapteryx excellens. (I'lato CXXXV. fig. 13.) 



Creamy white : primaries sliglitly tinted witli sulphur-yellow; costal margin narrowly 

 black ; an oblique dark grey band, commencing just beyond the basal fourth of eosta, and 

 running to about the external fourth of inner margin, continued as a slender blackish line 

 almost to external angle, where it unites with a second similar baud from third fiftii of costa; 

 between these two bands is a dark grey discocellular stripe ; a longitudinal dark grey stripe 

 along the submedian vein from the base to the first oblique band ; fringe of inner margin 

 grey, tipped with white; costal area towards the base crossed by short dark grey lines, two 

 of which are also present between the two grey bauds ; disc transversely striated with blackish 

 lines; outer margin, excepting at external angle, black, with dark grey fringe : secondaries 

 with a bright yellow band near outer margin from first subcostal to first median braneii, 

 bounded internally by an oblique blackish streak and a series of groups of black scales ; first 

 median branch mottled with black ; submedian vein black; five black marginal spots ; fringe 

 dark grey, excepting at anal angle ; an apparently grey arched central band produced hy the 

 transparency of the wing, which renders the markings of the under surface visible above : 

 face spotted with brown in each corner. Under surface of wings pale stramineous, shading 

 into oehraeeous ; grey and blackish markings as above, but better defined, costal borders 

 blotched witli blackish : secondaries with a small black spot at the end of the cell followed by 

 an arched black band from third fifth of costa to extremity of interno-median fold : body 

 below white; legs mottled with black. Expanse of wings 52 millim. 



Cashmere. 



In form this species comes nearest to U. maculicaudaria ; but in colouring it is unlike 

 any other described Urapteryx ; it somewhat reminds one of Tristrophis veneris, but the 

 ueuration is that of the typical genus. 



ENNOMID^. 



TETRACIS, Guea* 



Tetracis indica. (Plate CXXXV. fig. 16.) 



Pale brown, the primaries and abdominal half of secondaries slightly suffused with pink; 

 a slightly darker central band with dentate-sinuate greyish edges, the denticles iudicated here 



* Represented by a female example only, the palpi of which are injured ; it is therefore possible 

 that it may represent the type of an allied new genus.
