TORTRICINA. 311 



Genus VIII. LOZOPERA, STEPHENS. 



Palpi longer than the head, ascending, remote, diverging ; basal 

 joint slender, truncate ; apical slender, club-shaped, exposed, as long 

 as the basal ; middle slightly arcuated, thickest beyond the middle, 

 three times as long as the apical. Maxillae moderately stout, as 

 long as the palpi. Thorax stout, subovate. Anterior wings elongate, 

 in some cases more than three times the width (L. Francillana and 

 dilucidana) ; costa straight, or very slightly arcuated ; apex acute ; 

 apical margin obliquely truncate ; dorsal margin very slightly 

 rounded ; cilia at the anal angle produced. The costal vein reaches 

 to the middle of the margin. The subcostal nervures equidistant. 

 Discoidal cell capacious, widest beyond the middle, not proceeding 

 two-thirds along the wing ; the apical nervures extended. Posterior 

 wings elongate ; apex obtuse ; apical margin very concave ; basal 

 angle slightly produced. Abdomen slender ; stouter in the , a 

 small tuft at the apex in the tf . 



The insects in this genus have the anterior wings pale yellow, 

 or primrose-colour, marked with fasciae which lie parallel to the 

 apical margin. In general appearance not far removed from 

 Eupoecilia, but in stature generally larger, some of the species 

 (straminea, alternana) considerably so. Like the preceding genus, 

 the larvae are not sufficiently known for the purposes of classifica- 

 tion, but are probably all internal or seed feeders. 



There are five British species in this genus, which are thus 

 tabulated : 



A. Anterior wings with oblique strigae, distinct and 

 denned. 



a. With two distinct oblique strigae, that nearest 



the base abbreviated Species . 1 



6. With two distinct oblique strigae, both entire . Species . 2 

 c. With two distinct oblique strigae, both inter- 

 rupted Species . 3 



B. Anterior wings with oblique strigae, indistinct or 

 interrupted Species 4-5 



1. dilucidana, Steph. Alia anticis pallide flavis, ante medium mar- 



ginis dorsalis striga abbreviata, obliqua ; pone altera quae costam 



attingit, rufo-brunneis ; posticis griseis. $ Exp. al. 6 J lin. 



Head and face straw-colour. Eyes black. Palpi as long as the 



head, straw-colour. Antennae pale fuscous. Thorax and patagia 



straw-colour. Anterior wings straw-colour, with the costa very 



narrowly edged and maculated with ferruginous to beyond the 



middle, and two oblique ferruginous streaks parallel with the apical 



margin ; the anterior commencing on the dorsal margin one-third 



from the base, and extending only to the middle of the wing the
