Utriculofera fuscapex. (Plate CLYIII. fijjs. 7, 17.) 



Expanse i iuch. 



Male. Fore wing dusky greenish grey ; the hase and apes fuscous ; a dark streak on the 

 eentre of the costa. Hind wing and underside of fore -ning fuscous, of liind wing ])aler. 

 Female without tlie dark base and streak on fore wing. 



ANDROSTIGMA, g. n. 



Diflers from Didut/a, Moore, in the male having bipectinated antennEe, the branches 

 being short, strong, and ciliated, and a large sexual brand of large scales with rounded ends near 

 the anal angle of hind wing. Venation as in Diduga : fore wing with a costal veiu ; two 

 subcostals before the end of cell ; the third and fourth from the end, the latter bifid ; a radial 

 from close to upper end of cell ; the lower radial and third median from the lower end ; 

 the second median from close before the end; the first median from long before the end; the 

 submedian nearly straight. Hind wing with a costal vein ; the subcostal forked before the 

 apex ; the third median from the lower end of cell ; the second from just before, the first from 

 long before, the end ; submedian and internal nervures. 



Androstigma albicosta, Hmpsn. (Plate CLVIII. fig. 25.) 



Diduga albicosta, Unipsii. III. Typ. Lep. llet. B. M. viii. pp. .5, 53, pi. cxl. fig. 17. 



Expanse ^ § inch. 



Male. Differs from the female in having bipectinated antennae and a large secondary 

 sexual patch of mouse-coloured scales near the anal angle of the hind wing. 



Pseudoblabes oophora, Zell. (Plate CLVIII. fig. 14.) 



I'scudoblabes oophora, Zell. Bull. Soc. Mosc. 1853, p. 514. 



Expanse ? % inch. 



Female. Differs from the male in the costal fold on the underside of the fore wing being 

 slighter; the hind wing is fuscous, the apex not excised, and without the tuft of raised scales. 



This genus resembles Padeniu in the strong costal fold to the fore wing and the excised 

 apex of the hind Aving in the male ; but diflers from it in venation and in having a patch of 

 modified scales below the costa of the liind wing instead of a tuft of hairs on the costa in 

 the male. Zeller's description of the venation is unsatisfactory, and his figure much more so; 

 in the fore wing the fifth subcostal comes off from the end of the cell Avhich is closed; in the 

 hind wing the costal is emitted close to the end of the cell, running through the patch of 

 scales to the apex ; the subcostal bifurcates before the margin ; the cell is open, the median 

 nervure gives off the first and third medians, the second nunlian and discoccllular being 

 aborted fragments wliich end abrujjtly. I;i tlie female tlie cell of the bind wing is closed, 

 there is a radial from the discocellulars, and two median ncrvules.
