212 THE CANADIAN ENTOMOLOGIST 



SUNFLOWER INSECTS IN VIRGINIA AND CONNECTICUT 



BY T. D. A. COCKERELL, BOULDER, COLO. 



Last August I visited Mr. S. A. Rohwer, at Falls Church, 

 Va., and with his assistance obtained a series of insects from the 

 sunflowers (Heliannius anntms van zonatus) growing in his garden. 

 The list is as follows : 



(A) Visiting the Flowers. 



Lepidoptera: Anosia plexippus L., sucking. 



Hymenoptera: MeUssodes dentwentris Smith, both sexes; 

 Melissodes caliginose Cress., 9 ; Apis mellifera L., worker; Bombus 

 consimilis Cress., worker; B. americanorum Fb., worker; Halicttis 

 capitosiis Sm., 9 s. 



(B) On Foliage. 



Hymenoptera: (Determined by Dr. W. M. Wheeler, who 

 was present at the time). Formica pallidefidva Latr. and var. 

 nitidiventris Emery. 



Hemiptera: (Determined by Mr. O. Heidemann). Entylia 

 concisa Walk., breeding on leaves; Ilnacora stalii Renter, breeding 

 on leaves. 



In addition, a species of aphid {Macrosiphum) was found, of 

 which we can only say now that it differs from any recorded from 

 Helianthiis. 



On Sept. 11, Dr. W. M. Wheeler very kindly collected insects 

 on sunflowers {Helianthiis annuus var. macrocarpiis) at Colebrook, 

 Conn., (alt. 1200 ft.), and sent me the specimens. The list is as 

 follows : 



Hymenoptera: Myrmica scahrinodis subsp. schenki var. 

 emeryana Forel (Oct., Wheeler); Bombus consimilis Cress., six 

 workers having the yellow pubescence brighter than in examples 

 from Garrison, N.Y.; B. Jervidus Fb., one male and six workers; 

 Melissodes d enliven Iris Sm., 9 ; Megachile latimanus Say, 9 . 



Hemiptera: Lygus pratensis L., and a species not recognized. 



Diptera: Eristalis, Syrphus and Sphcerophoria. 



At Boulder, Colorado, in September, 1916, 1 observed numerous 

 moths one evening visiting the red sunflowers. On collecting a 

 number, I found they were nearly all Feltia snbgothica Haw. 



June, 1917
