Lepidoptera. 57 



Anal vein in fore wing simple; tosta of hind wing strongly lobed, with the 

 obscure basal parts of the subcosta and radius closely parallel to the edge 



of the lobe. (Lithocolletes, Gracilaria, Omix.) GRAdLARIID.^ 



is. Subcosta and radius in hind wing nearly straight and parallel toward base, 

 usually connected by a distinct, but weak crossvein; rarely, when subcosta 

 is very short, this vein enters the costa beyond the tip of the subcosta; 

 when the costa is lobed, with the subcosta fairly straight, and ending at 

 the commencement of the concave portion 7R 



Subcosta and radius sharply divergent at base; first radial vein, when traceable, 

 appearing as a basal fork of the subcosta, oblique, short and heavy, and the 

 radial stem running nearly through the axis of the wing; or with the sub- 

 costa and radius both obscure, closely parallel to the basal lobe of the costa, 

 and the radius functionally replaced by the base of the media 77 



76. Palpi upturned to the vertex. (Mompha, Cosmopteryx, Coleophora [C- 



vialivorella). Pistol case-bearer; C. fleicherella. Cigar case-bearer]) (PI. 9, 



fig. 208) COSMOPTERYGm^ 



Palpi minute, drooping. (Heliodines.) HELIODINID.^ 



77. Maxillary palpi present, porrect (see couplet 74) GRACILARIIDyE, part 



Maxillary palpi absent 78 



78. Cubital stem in hind wing at least two-branched; palpi usually smoothly 



upturned to vertex; hind tibiae loosely hairy. (Elachista.) 



ELACHISTIDiE 

 Cubital stem in hind wing simple, free; no cell, or with very short palpi .... 79 



79. Basal joint of antennae broadened with overlapping scales (a vestige of an 



eyecap); tongue weak; cubitus in hind wing simple; hind tibiae with a regular 



series of bristles. (Phyllocnistis, part) (see couplet 61) LYONETIIDiE, part 



Basal joint of antennae simple, or with a slight comb of bristles 80 



80. Palpi usually hanging, if upturned, not reaching the middle of the front. 



(Heliozela, Antispila, Coptodisca, Cycloplasis.) HELIOZELID.^ 



Palpi moderately long and usually slender, upturned in life (see couplet 74). 



GRACILARIID^ 



81. Second branch of the cubitus in the fore wing arising less than two-thirds way 



out of the cell; rather or quite small moths, the fore wings frequently 

 more or less truncate or faintly excised at the tip. Leaf-rollers. (Ole- 

 threutes, Eucosma, Spilonota (= Tmeiocera) [S. ocellana, Bud-mothl 

 Ancylis [A. comptana. Strawberry leaf-roller], Enarmonia [E. prunivora^ 

 Lesser apple-worm], Carpocapsa (=C2/cZia) [C. pomonella. Codling-moth], 



Archips, Tortrix.) INIost TORTRICID^ 



Second cubital vein in fore wing arising further out of the cell 82 



82. Wing membrane prickly; subcosta in hind wing with a strong basal fork, or 



considerably swollen at base; radius and subcosta usually sharply divergent 

 from the base; antennae often extremely long; vertex very rough. (Inciir- 



varia, Adela, Cyane.) ADELIDjiE, part 



Wing membrane not prickly; antennae never much longer than the fore wing; 

 first radial rarely as strong as the other veins, and when distinct, separated 

 from the base of the wing by several times its length 8S
