ZENILLIA AND ALLIED GENERA — SELLERS 65 



Rhode Island (Johnson, Schaffner and Griswold), Connecticut 

 (Schaffner and Griswold), New York 4 (West), New Jersey (Smith), 

 District of Columbia (Coquillett, Townsend), Maryland (Hill), 

 Kansas (Tucker), Quebec (Winn and Beaulieu), Puerto Rico (Wol- 

 cott). Owing to the confusion surrounding the earlier identity of 

 this species, the author is of the opinion that some of the above re- 

 corded published records may be erroneous. 



Type.— Female, U.S.N.M. No. 3596. 



Hosts. — Hemerocampa leucostigma (Abbot and Smith) 90; Notolo- 

 phus antiqua (Linnaeus) 1, Porthetria dispar (Linnaeus) 1. Pub- 

 lished records: Plathyp&na scabra (Fabricius) (Hill) and Ecpan- 

 flirrhi e rid a mis (Cramer) (Wolcott). 



Remarks. — The foregoing description is based on an examination 

 of the type specimen; the female type, Sisyropa hemerocampae, 

 U.S.N.M.' No. 12623, G.M.L. 820-0 07TD 2060 B, previously deter- 

 mined as Exorista griseomicans by Coquillett ; 90 reared specimens 

 bearing Gypsy Moth Laboratory note numbers ; one male reared from 

 Notolophus leucostigma (Schoene) ; two females G.M.L. 558 T (one 

 without ocellar bristles) ; one male and three females, 205 04T July 1896 

 labeled as griseomicans; one male and one female, 5332 B and 5332 

 BC, female labeled griseomicans; two males and one female, G.M.L. 

 2685 A, August 1909, labeled as S. hemerocampae; one male, 205 043 , 

 July 23, 1897; one female, Toronto, Ontario (Brodie). 



The species as now constituted is still a variable one. The main 

 variable factors are the color of the first two segments of the antenna 

 being red or black, three or four dorsocentrals, and the inner ventral 

 bristle of the midtibia being weakly present or lacking. As there is 

 no clear line of demarcation, nothing is to be gained by recognizing 

 these variations as having specific status. The writer was unable to 

 find any correlation between these factors or any others noted that 

 would warrant further restricting the material placed here. 



Adults, June to October; number per host, one; generations one or 

 two depending upon the locality; hibernation, in the puparium. 



In the past there has been a tendency to refer some specimens of 

 Carcelia amplexa and C. diacrisiae to Exorista griseomicans Van der 

 Wul p. The writer had the privilege of examining the type series of 

 E. griseomicans, which is located in the British Museum. This ma- 

 terial is a composite series composed of three species of Carcelia 

 which resemble, but are distinct from C. formosa, C. gnava, and 

 C. Jagoae.
