TOKTRICINA.

twice the width. Costa arcuated. In the <$ the fold scarcely reach- 

 ing to the middle ; apex acute; apical margin oblique, concave ; dorsal 

 margin rounded. In this genus the apical vein gives out five nervures, 

 the first of which is furcate. Posterior wings : apex acute ; apical 

 margin concave. Abdomen slender, tufted in both sexes, but mostly 

 so in the <$ . 



This genus was established by the late J. F. Stephens for the 

 reception of the only species which it contains, but it appears to 

 us scarcely to offer sufficient distinctive characters on which to 

 found a genus ; but as it has figured as distinct, not only by 

 the author quoted, but also by M. Guenee, under the name 

 " Teratodes" it is thought better to retain it in that position. 

 Further observations, as respects its larva and transformations, 

 may show whether or not its claims to remain distinct can be 

 maintained. 



1. ochraceana, Steph. Alis anticis ochraceo-griseis, cinereo-fusco 

 obsolete reticulatis, in medio fascia abbreviata indistincta ; posticis 

 nitidis, griseis. <5" Exp. al. 6-6^ lin. 



Head and face straw-colour. Eyes black. Palpi longer than the 

 head, straw-colour. AntennaB slightly ochreous. Thorax and patagia 

 straw-colour, sometimes irrorated with fuscous. Anterior wings dull, 

 dusky straw-colour, with fuscous markings, forming a broad, un- 

 defined, oblique, irregular fascia before, and another paler, narrower 

 one beyond, the middle ; both most distinct towards the costa. The 

 apical margin narrowly edged with fuscous. Apical scales dull, 

 ochreous, with fuscous tips. Cilia ochreous. Posterior wings dull 

 pale grey, with a slight fuscous tinge. Marginal scales grey, the 

 bases pale ochreous. Cilia pale ochreous. Legs straw-colour. Ab- 

 domen fuscous, the caudal tuft ochreous. $ Exp. al. 6-6^- lin. 



Not a very uncommon species. In appearance it much re- 

 sembles dull specimens of Dictyopteryx Lceflingiana, but the ^ 

 may be readily distinguished from it by the folded costa. 



The imago appears in May and June, and occurs throughout 

 the country. 



The larva is attached to the Hornbeam. 



Genus XV. CARTELLA, GUENEE, olim. 



Palpi twice the length of the head, remote, porrected horizontally, 

 clothed with moderately long scales. Basal joint drooping, stout, 

 pyriform, truncate ; apical club -shaped, thickest towards the apex, 

 longer than the basal ; middle ascending, curved, club-shaped, mode-
