GRACILARIIDyE. 525 



antennas as long- as the forewings; labial palpi slender, terminal joint acuminate; 

 maxillary palpi rather long, filiform. In repose, the species of this family sit on the 

 base of the abdomen, having the head raised fi'ora the surface, the anterior pair of 

 legs being put forward, the middle pair rather stretched outward sideways, and the 

 posterior pair placed close beside the abdomen. 



" Larva with 14 legs ; mining or rolling up leaves."— (Siai/iiow.)

 (1861). 



" Blackish above. Wings with a few silvery spots. Greyish beneath. 



" Expanse 2 lines." 



Ceylon. — (Nietner.) 



" The larva mines the leaves of the coffee-tree, and the ugly white lines and 

 blotches so frequentlj-. — and at all seasons — seen upon the leaves are its work. The 

 larva is 2^ lines long, yellow, flat, naked, imdulated at the sides, tapering towards 

 either extremity ; eye and footless ; head brown, pointed at the extremity ; and one 

 half retractile; it is furnished near the extremity with two. antennal appendages, 

 each with three hairs at the tip ; the jaws are large and quite free at the extremity 

 of the head, moving between two large reniform lips, which gives the head a curious 

 appearance ; the penultimate segment is the smallest and is furnished with two 

 spurs pointed outwards. Pupa If hues long, blackish in the middle, and yellow at 

 the extremities ; the head finishes in one and the tail in two spines; antennas and 

 feet are free at the extremity. It rests for a short time under the epidermis in a 

 sort of cradle." — {Nietner.) 



Family ELACHISTIDiE. 



"Forewings oblong or elongate : hindwings lanceolate or linear-lanceolate. 

 Head generally smooth ; labial palpi slender, filiform, mostly recurved and pointed. 

 In repose, most of the genera sit closely appressed to the surface on which they rest. 

 Flies mostly at dusk, but sometimes in little swarms in the afternoon. 



" Larva with 16 legs ; mostly mining in leaves." — {Stainton.)
