Records in the literature recording possible hosts were found in 

 Weiss and West (1921): "Alojiachus ater Hald, Monmouth Jc, N.J. 

 July 14 on leaves of Apocynum androsaemifolium L." and in Blatchley 

 (1910) : "Occurs on foliage of milkweed and other herbs." 



Attempts at rearing adults of this species in the laboratory on 

 Ewpatorium purpureum were not successful. 



Type: This specimen was noted to be in the Bosc collection accord- 

 ing to Fabricius when he described the species. Mrs. Doris H. Blake 

 of the U.S. National Museum informed the author (pers. comm.) 

 that this specimen was not there when she viewed two boxes of Bosc 

 material in Paris in 1950 (see also Blake, 1952). This specimen was 

 likewise not found among the Fabrician types in the Universitetes 

 Zoologiske Museum, Copenhagen, Denmark (S. L. Tuxen, pers. 

 comm.). Neither was the type distinguished from among Suffrian 

 material loaned by J. O. Hiising, Martin Luther Universitat, Halle- 

 Saale, East Germany. As Fabricius' type may one day be found, and 

 no current dilemma results without it, a neotype was not designated. 



Type locality: "Habitat in Carolina" (Fabricuis, 1801). As the 

 type was to have been in the Bosc collection it was most likely 

 collected by him at or near the Michaux gardens at Charleston, S.C. 

 (Blake, 1952). 



Distribution: Collections of this species have been made in the 

 eastern United States and Canada westward to about the 100th 

 meridian. Specimens totaling 2174 were examined from the following 

 localities : 



CANADA: Alberta: Walsh, "Ont." [probably Alberta]. Manitoba: 

 Aweme; Delta; Douglas Lake, Aug. 30; Rennie, June 3. New Brunswick: 

 Bathurst, July 7; Sackville, July 6. Nova Scotia: Castlereigh. Ontario:
