TORTRICINA. 287 



Genus V. ARGYKOLEPIA, STEPH. 



Palpi considerably longer than the head ; basal joint stout, pyri- 

 form, truncate ; apical minute, stout, somewhat egg-shaped, not so 

 long as the basal ; middle stout, curved, ascending, thickest beyond 

 the centre, four times as long as the apical. Maxillae not so long as 

 the palpi. Thorax robust, ovate. Anterior wings : length exceeding 

 twice the width, elongate, triangulate ; costa slightly arcuated, or 

 nearly straight ; apex obtuse ; apical and dorsal margins rounded ; 

 cilia produced at the anal angle. The costal vein reaches to the 

 middle of the margin ; subcostal nervures equidistant. The discoidal 

 cell capacious, widest beyond the middle, extending scarcely two- 

 thirds the length of the wing. Posterior wings : apex obtuse ; apical 

 margin concave ; anal angle slightly produced. 



A genus of considerable extent ; some of the species rare, but 

 none of common occurrence. They are mostly ornamented on 

 the anterior wings with minute silvery spots and streaks. In 

 repose these insects sit with their wings very deflected, and 

 closely adpressed to their sides, after the manner of the Eupoe- 

 cilice, to which they bear several points of affinity. The larvae 

 are all (?) of them internal feeders, but their individual habits 

 have not been sufficiently observed.
