Aivchylopera achat ana, Fab. 1 — 2 



Valva curved on its outer edge; sacculus angulate, point 

 rounded. Cornuti sigmoid. 



Ostium wide, minutely spined, broad band, curved. 



VII. EPIBLEMIDII. 



A large group in which the male genitalia are more or less 

 uniform, but the pilleate form of the female signa is the 

 chief characteristic. 



Genus 1. Acroclita, Ld. type subsequana, H — S. 



= consequana, H — S. 



The exact position of this species is difficult to locate. 

 The valva and angulate sacculus denote an affinity with the 

 preceding genera. The general formation of the valva, the 

 Ions scales from the dorsal surface of the uncus, and the 

 double signa all bring it into close affinity with the species 

 included in the genus Zeiraphera; the nearest relatives 

 being ratzeburghiana, rufimitrana and occtUtana, but the 

 extraordinary development of the subuncal parts and the 

 non-retractile ovipositor place it in a genus by itself. 



Acroclita subsequana H — S. 1 — 1 



Valva simple, rounded: sacculus with inwardly projecting 

 lobe. Uncus roughly bilobed, thickly clothed with very long 

 scales; arising centrally from either side of the uncus is a 

 lobed plate set at its edge with long spines; below this at 

 either side is a bifurcate projection, which may be a modified 

 gnathos, the outer arm curved naked, the inner arm 

 emitting bwo or three spines. Cornuti eight, deciduous. 



Ovipositor flattened. Ostium simple, spined behind; 

 signa two, pointed, scobinate. 



Genus 2. Zeiraphera, Tr. type corticana Hb. 



A small genus, closely connected with the [(receding genus.
