42 TINEID. 
slightly posterior; cilia dark purplish-fuscous, the tips at the apex 
whitish. Posterior wings pale grey, with a slight purplish tinge; cilia 
pale grey. 
Common among currant-bushes at the end of May. The larva 
is very injurious, eating the pith of the young shoots, and betrays 
its presence by the withering of the young leaves; when quite 
young it is dark red, but when full-fed it is greenish-white.

Caput superne hirsutum, orditis superioribus late nudis. Ocelli distincti, 
ab oculis distantes. Palpi maxillares 6-articulati, plicati. Palpi 
labiales breves, cylindrici, pilosi. Antenne alis anterioribus brevi- 
ores. Haustellum breve. Ale anteriores oblongo-ovatie ; vena sub- 
costalis ramos 4 in costam emittit. Posteriores ovate, piloso-squa- 
matze, ciliis mediocribus. 
Head above clothed with long hairs, a@ broad space above each eye 
naked. Ocelli distinct, rather remote from the eyes. Maxillary palpi 
six-jointed, folded. Labial palpi short, cylindrical, hairy. Antenne 
shorter than the anterior wings (in some of the species much shorter). 
Tongue short. Anterior wings oblong-ovate, glossy and rather trans- 
parent. Posterior wings ovate, rather transparent, clothed with long 
hair-formed scales, with moderate cilia. 
The perfect insects fly in the sunshine; the smaller species 
among flowers in June; the larger species among birches, ete., in 
April and May. None of them appear to be double-brooded. 
The larvee are still entirely unknown to us: this is the more un- 
fortunate, as some of the species are so very similar in markings 
and habits, that till we ascertain their transformations we cannot 
feel confident of their distinctness.
