smooth. Fore wings narrow, slender, lanceolate, pointed, smooth ; costa somewhat 

 depressed at middle of wing. lo veins, 4 and 8 absent, all separate, 7 to costa, i^ 

 forked at base. Hind wings under I, lanceolate, 6 veins, 3 and 4 absent, cell open, 

 5 and 6 stalked from independent stem, 7 independent. Hind tibice smooth with two 

 groups of long, stiff bristles above the spurs, one at the middle, the other at the end. 

 At rest the hind legs are stretched upwards above the wings. 



Type : ^. pispniella Bu.sck. 



This genus resembles very much Lifliariaptoyx, Chambers (Can. 

 Ent., VoL VIII, p. 217, 1876), in head, wing form, venation and gen- 

 eral habitus ; but it is distinguished at once by the two groups of stiff 

 bristles on posterior tibiae and differs also in the forewing by having 

 vein lb distinctly and greatly furcate at base while in the hindwing 

 the submedian vein is simple.

 flections. At base is a dorsal aureous patch and at the middle of the wing is a nar- 

 row transverse aureous fascia ; at basal fourth is a small black costal dot, surrounded 

 by metallic purple scales. Cilia dark ashy gray. Hind wings silvery gray becoming 

 darker outwards towards the top where they are shining purplish black. Cilia with a

U. S. National Museum, type no. 5357. Cotype in collection of 

 Dr. Meyrick, England. 



Described from four specimens, bred in February from Pisonia ob- 

 tiisata, collected by Dr. Harrison G. Dyar. 



The moth is a shining, elegant little form, related to and remind- 

 ing one of Heliodines. The following are Dr. Dyar's notes on the 

 larva : 



"The larva lives on the leaves of Pisonia obti/sata, at first mining 

 between the upper and lower epidermes, later eating little patches on 

 the back of the leaf through to the upper epidermis from a position in 

 a central white web, covered by a lump of frass which adheres to the 

 web. In one instance the larvae were found on Pisonia aculeata with 

 the same habits. 



" Slender, monilifomi, joint 13 narrower ; transparent whitish-green, tubercles 

 represented by tiny black dots. Head flattish, the clypeus high, nearly touching the 

 vertical triangle ; whitish, ocelli black, mouth pale brown. Tubercles i and ii are in
