13. Genus SCIAPHILA Treitschke 



(Figs. 17, 51) 



Sciaphila Treitschke, Schmet. Eur., vol. 7, 1829, p. 233. {—Peribrosca 

 Gistel). 



Genotype. — {Phalaena Tortrix icahlbomiana JAnna.e\is)=Phalaena 

 Tortrix hranderiana Linnaeus (Europe). 



Thorax with posterior tuft. 



Fore wing smooth; termen convex; 12 veins, all separate; 7 to 

 termen; 8 and 9 approximate; upper internal vein of cell from be- 

 tween 10-11; 3, 4, and 5 not approximate at termen; 2 from cell 

 Tbefore %, straight. 



Hind wing with 8 veins; 6 and 7 approximate toward base; 3 and 

 4 connate; termen evenly rounded; male without chitinous ridge at 

 -inner margin. 



Hind tibia of male without hair pencile. 



Male genitalia with harpe elongate, slender, broadened beyond 

 base; outer surface spined; cucullus broadened toward apex; neck 

 long and slender; sacculus not extended in an arch pocketing neck; 

 spine clusters Spc"^ and Spc- strongly developed and closely ap- 

 proximate ; sacculus weakly spined toward base. Uncus short, broad, 

 lobed, rather densely spined. Tegumen narrowly elongate. Socii 

 almost obsolete. Gnathos with prominent, moderately chitinized, 

 spatulate, flattened subanal plate. Aedoeagus short, stout, expand- 

 ing toward apex and more or less scobinate; cornuti absent. 



Female genitalia with two signa; latter developed as sharp, 

 ■elongate, narrow, strongly chitinized blade-like projections. Ductus 

 bursae moderately long; simple (chitinized only toward genital 

 opening). 



A genus closely related to Aphania. Contains one North Ameri- 

 can species. 



Pierce and Metcalfe ^^ make wahlhomiana a synonym of hranderi- 

 ana. Under the former name European authors have hitherto identi- 

 fied quite a different species. In consequence of which Sciaphila has 

 heen sunk to Cnephasia. It seems strange that all should have made 

 such a mistake; and I am still somewhat sceptical about the cor- 

 rectness of the new synonymy. However, as Pierce and Metcalfo 

 state that they have compared the Linnaean types there is nothing 

 to do but to follow them and remove Treitschke's generic name from 

 the Tortricidae and apply it here.
