NORTH AMERICAN" LASPEYBESIINAE AND OLETHREUTINAE 25 



8. Genus SEREDA Heinrich 



(Figs. 29, 118) 



Sereda Heinkich, Proc. Ent. Soc. Washington, vol. 25, 1923, p. 121. 

 Genotype. — Halonota lautana Clemens (North America). 

 Thorax smooth. 



Fore wing smooth ; termen covex ; 12 veins, all separate ; 7 to ter- 

 men; 11 from cell before middle; 10 approximate to 9; upper inter- 

 nal vein of cell from between 10 and 11 ; 3, 4 and 5 remote at termen ; 

 2 from cell just before Y2 5 straight; no costal fold in male. 



Hind wang without pecten on lower median vein ; 8 veins ; 6 and 7 

 approximate toward base ; 3 and 4 connate ; inner margin simple in 



male. 



Male genitalia with outer surface of harpe unspined ; cucullus trig- 

 onate ; neck ver}^ slender ; neck incurvation deep ; sacculus enlarged, 

 weakly spined. Tegumen a narrow chitinous band. Uncus absent. 

 Socii absent. Gnathos a simple, weakly chitinized band. Aedoeagus 

 long, stout, slightly bent, scarcely tapering; cornuti 3 or 4 short, 

 stout fixed and a cluster of deciduous spines. ~^ 

 Abdomen of male with a pair of long hair tufts from lateral ex- 

 tremities of sternite of eighth abdominal segment. 



Female genitalia wath two signa, developed as thornlike spines. 

 Ductus bursae short, chitinized and bent. 



A monotypic genus derived from GrapholitJia. The absence of 

 pecten is rare for the family, occuring elsewhere, as far as I know, 

 only in Satronia and Goditha.

Easily identified by structural characters and the strong black dots 

 along termen on upper and under side of fore wing. In one specimen 

 in the National Collection veins 7 and 8 of fore wing are stalked. 

 This, however, is very unusual. In all other specimens I have seen 

 they are distinctly separate. 



Genitalia figured from specimens in National Collection from Ox- 

 bow, Saskatchewan (I^ab, "15-V-07," male), and New Brighton, 

 Pa. (Merrick, "4-14-03," female).
