STEPS TOWARDS A REVISION OF CHAMBERS' INDEX, WITH NOTES 

 AND DESCRIPTIONS OF NEW SPECIES. 



By Lord Walsingham. 



[Continued from p. 155. J 



Adela flamensella Chamb. 

 =:lactimaculella Wlsm. 



This species was originally described from a very bad specimen with antennas and 

 palpi broken off and therefore presumably with the wing more or less worn. 



Imperfect specimens of lactimaculella, female, in my own collection agree with the 

 description in having no markings, except a minute whitish spot at the beginning of 

 the costal cilia. The saffron head of the female is also characteristic. Good speci- 

 mens of the male (which has a black head), show three distinct spots, two costal and. 

 one intermediate and dorsal. 



Adela simpliciella Wlsm. 



A unicolorous species allied to rufimitrella Scop, and violella Tr. It can not be con- 

 fused with any North American species, being much smaller than bella Chamb. 

 A very small form apparently undistinguishable from this species occurs in Texas.. 



Adela punctiferella sp. n. 



Antennce, $ , 13 mm long, whitish tinged with fuscous towards the base. 



Palpi, roughly clothed, hoary ; the naked apical joint slightly tinged with purple 



above. 

 Head and face, roughly clothed, hoary. 

 Thorax, greenish bronze. 

 Fore-wings, greenish-bronze, with a small indistinct whitish spot at the end of the cell,. 



a little above the middle of the wing; cilia shading from greenish-bronze to 



greyish at their tips. 

 Hind-wings, deep violet, with greenish-brown margins ; cilia as in the fore-wings. 

 Underside of both pairs of wings, violet, sprinkled outwardly with greenish- bronzy 



scales. 

 Abdomen, fuscous, hoary beneath. 

 Exp. al., 10™ m . 

 Hab., Los Angeles, Cal. 

 Type, 9 , Mus. Wlsm. 



I am indebted to Dr. Riley for the specimen from which this small but distinct 

 species is described. 



Adela bellella Wlk. 



= degeerella Emmons (nee L.). 



Walker describes this species as closely allied to degeerella L. and I mentioned (P. 

 Z. S., 1880, 78) that it differed from that species "only in the richer coloring and 

 in the darker purple hind wings. The longitudinal stripes before and beyond the 

 central band, as well as the margins of the band itself, are very distinct and of a 

 brilliant shot purple-blue, whereas these and the central band itself are paler in the 

 European species." 



Specimens received from Japan are apparently undistinguishable from this species 

 as represented by Walker's type in the British Museum, but without a careful study 

 of the numerous degrees of variation in the many allied Asiatic forms, of which I 

 have a large number of specimens, it would be unsafe to attempt to define its geo- 

 graphical range.
