ZENILLIA AND ALLIED GENERA — SELLERS 101 



Hampshire, Massachusetts 2, New Jersey, Maryland, District of Co- 

 lumbia, Virginia, and Missouri. 



Type. — University of Kansas. 



Hosts. — Euthisanotia {Eudryas) grata (Fabricius) 17, Euthisano- 

 iia unio Hiibner 1, Euthisanotia sp. 3. Published and unpublished 

 records not duplicated in above material: Euthisanotia grata (Brim- 

 ley, Ely, and Tothill), Euthisanotia unio (Brimley) ; Automeris io 

 (Fabricius) (Porter). Coquillett records Acronycta sp. (Koebele, 

 Lugger, and Riley), Acronycta luteicoma Grote and Robinson 

 (Riley), Heterocampa marthesia (Cramer) (Lugger), Vanessa ata- 

 lanta (Linnaeus) (Sprague). The author feels that all but the first 

 three host records should be viewed with some suspicion. 



Remarks. — The foregoing description is based on 1 female "from 

 the type lot of eudryae," Cornell University, reared from Eudryas 

 (Comstock) ; 1 female, type specimen of Townsend's thompsoni (type, 

 U.S.N.M. No. 19136), from E. unio, Dayton, Ohio (Jewett) ; 12 

 reared specimens bearing Gypsy Moth Laboratory note numbers, 

 all reared from E. grata (1 male No. 12176 Fl, from Castleton, Vt., 

 having one fronto-orbital bristle on one side, agrees perfectly with 

 Townsend's type description) ; 1 male from E. grata (Saunders) ; 1 

 male ex E. grata, Raleigh, N. C. ; 1 male and 1 female from Eudryas 

 (Dimmock) ; 1 male and 1 female from E. grata (Dimmock) ; 2 males 

 from E. grata (Isely) ; 1 reared female (Riley) ; 4 males and 11 

 females collected by Brodie, Knab, and Shannon. 



Brimley's record of rearing this species from Estigmene acraea 

 most likely refers to a female of Carcelia reclinata, August 10, 1917, 

 Raleigh, N. C. (Brimley). 



Adults, April to August; number per host, one to eight; genera- 

 tions, one; hibernation, in puparium.

Although somewhat larger, this species is very similar to Sisyropa 

 eudyrae. The differences have all been cited in the table to the 

 species. Otherwise, the description is practically the same.

 vesical bristle, 10 in number on one side and 11 on other, extending
