Sorhagenia daedala, new species 



Figures 21, 44 



Maculation: as for S. nimbosa. Male genitalia: as in figure 21 

 (KWH slide 590); juxta(?) subcircular, orifice in center; uncus very 

 small, tapering gradually to broadly rounded apex. Female genitalia: 

 as in figure 44 (RWH slide 591); pregenital plate very narrow, 

 anterior arms divergent, reaching anterior margin of seventh sternum ; 

 apophyses anteriores and posteriores very slender, long. Alar 

 expanse: 9.5-10 mm. 



Holotype: d^, Mt. Shasta City, Siskiyou Co., CaUf., July 4, 1958, 

 J. Powell (RWPI shde 590, RWH wing slide 39), USNM type 66355. 



Paratype: same data as type, 1 9 (RWH slide 591), UCB. 



I have not been able to find any consistent differences in the habitus 

 or venation which would enable me to separate S. daedala from S. 

 nimbosa; therefore, the characters pointed out in the keys based on 

 the genitalia should be used.

Type-species: Chrysopeleia purpuriella Chambers, 1874, monobasic. 



Head: smooth-scaled, labial palpus recurved, third segment shorter 

 than second, apex acute; tongue scaled basally; maxillary palpus 

 folded over base of tongue. Forewing: patches of raised scales; 

 lanceolate, apex acute; 12 veins present; lb furcate basally; 2 present 

 at margin of wing; 3, 4, and 5 separate; 7 and 8 out of 6; 11 from

 reduced, apex turned, saccus developed as a triangle; vinculum narrow; 

 uncus a rounded lobe; aedeagus massive, larger than other parts of 

 genitalia, apex very acute; eighth sternum modified, lateral sclerotized
