292 Mr, E. Meyrick's descriptions of 



of margins, interrupted above angle, fourth linear, fifth terminal, 

 broad on costal half, linear and indistinct on dorsal half, separated 

 from fourth by a linear space ; a small black apical spot preceded 

 by a white mark ; cilia white, base mixed with fuscous and dark 

 grey, with a grey line before tips, becoming black above apex. 

 Hind wings and cilia dark grey. 



Tonga {Mathew) ; one specimen. 



ELACHISTID.E. 

 ECHINOSCELIS, n. g. 

 Head smooth, side-tufts rough, erect, spreading, forehead very 

 prominent between antennae, face very oblique inwards ; no ocelli ; 

 tongue well developed. Antennae three-fourths of fore wings, 

 serrate, basal joint broadly dilated to form an oblong eye-cap. 

 Labial palpi long, smoothly scaled, recurved, second joint some- 

 what exceeding base of antennae, rather compressed, terminal joint 

 longer than second, acute. Maxillary palpi rudimentary. Posterior 

 tibiae and first joint of tarsi clothed with very long rough stiff hairs 

 above. Fore wings narrow, lanceolate ; vein 1 apparently furcate, 

 2 from before two-thirds of cell, 5 and 6 rising out of 7, 7 to costa. 

 Hind wings linear-lanceolate, about half fore wings, cilia four; 

 veins 6 and 7 stalked, 7 to costa ; a pencil of scales from angle 

 of costa. 



This and the two following genera are all allied to 

 Cosmoptcri/x ; it seems probable that Protr.rocosma is the 

 original form of a group of which Echinoscelis, Cos- 

 mopteryx and Persicoptila are developments. 



168. Echinoscelis hemithia, n. s. 

 2 , 9 mm. Head and palpi ochreous-white, crown and thorax 

 blackish. Antennae ochreous-white, with three blackish bands on 

 terminal half. Abdomen grey. Legs ochreous-white, banded with 

 blackish. Fore wings light ochreous-yellow ; basal half blackish, 

 boimded by a straight slender central ochreous-white fascia, and 

 cut by an indistinct irregular ochreous-whitish fascia near base, 

 and a more distinct one at one-fourth ; cilia light ochreous-yellow, 

 becoming grey towards anal angle. Hind wings dark grey ; cilia 

 grey.
