Hind wing as broad as f orewing ; 8 veins ; 3 and 4 connate or stalked ; 

 6 and 7 somewhat divergent; 5 approximate to 4. Abdomen not 

 depressed. 



Male genitalia. — Harpe with sacculus very broad, deeply folded, 

 heavily sclerotized and clothed with long coarse hairs. Clasper long, 

 reaching to or beyond costa, usually dilated distally with apex armed 

 with short, stout spines. Cucullus narrow, lightly sclerotized, clothed 

 with fine hairs; apex rounded. Anellus broad, without lateral proc- 

 esses; lateral lobes wealdy developed, with few hairs. Aedeagus 

 long, slightly curved, apex pointed. Vinculmn broad, rounded. 

 Transtilla membranous with weak lateral hairy lobes. Gnathos long, 

 bluntly pointed. Uncus well developed, elongated, narrowly pointed, 

 moderately clothed with hairs. 



Female genitalia. — Ductus bursae membranous or narrowly sclero- 

 tized just before ostiiun. Signum present or absent. 



Remarks. — Meyrick'^^ has synonymized Inga with Cryptolechia^ 

 but the two are sufficiently distinct to justify their separation. The 

 male genitalia of Cryptolechia show a tubular anellus, spined, broad 

 gnathos and spoon-shaped micus, together with minor differences. 

 These characters, when compared with the description and figure of 

 Inga, will serve to distinguish between the two. 



As a means of separating the oecophorid genera, Busck, Meyrick, 

 and others have used the direction of vein 7 of the fore wing (to termen, 

 to apex, or to costa) . For the most part this character serves for sepa- 

 rating the genera into two groups, but in this genus we find all condi- 

 tions existing. In sparsicllieUa.^ obscuromaculella, canariella, and 

 concolorelJa 7 is distinctly to costa but in cretacea and ciliella it goes 

 to the termen scarcely below the apex. Normally veins 2 and 3 of the 

 forewing are widely separated but in some specimens may be either 

 connate or short-stalked. 



In view of the fact that aberrations in venation occur here and that 

 the genitalia indicate that the species are unmistakably congeneric, 

 we may well associate them. 



On the abdominal segments of the males of concolorella and ciliella 

 and the females of canariella there are spines such as are commonly 

 found in the Blastobasidae. The spines in Inga, however, differ from 

 those found in the Blastobasidae by being dilated toward their ex- 

 tremities; those of the Blastobasidae (studied) are evenly tapered 

 to a sharp point. The spines of loiga are, in most cases, readily de- 

 ciduous, those of Blastobasidae more firmly attached. 



Busck *^ erected this genus for Anesychia sparsiciliella Clemens. As 

 already pointed out Meyrick considered the genus synonymous with
