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 {Helianthiis annuus var. zonatiis) growing in his garden. 
The list is as follows: 
(A) Visiting the Flowers. 
Lepidoptera: Anosia plexippns L., sucking. 
Hymenoptera: Melissodes dentiventris Smith, both sexes; 
Melissodes caliginose Cress., 9 ; Apis mellifera L., worker; Bomhiis 
consimilis Cress., worker; B. americanontm Fb., worker; Halictus 
capitosiis Sm., 9 s. 
(B) On Foliage. 
Hymenoptera: (Determined by Dr. W. M. Wheeler, who 
was present at the time). Formica pallidefuha Latr. and \'ar. 
nitidiventris Emery . 
Hemiptera: (Determined by Mr. O. Heidemann). Entylia 
concisa Walk., breeding on leaves; Ilnacora stalii Reuter, breeding 
on leaves. 
In addition, a species of aphid {Macrosiphiim) 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. macrocarpus) at Colebrook, 
Conn., (alt. 1200 ft.), and sent me the specimens. The list is as 
follows: 
Hymenoptera: Myrmica scabrinodis subsp. schenki var. 
emeryana Forel (Oct., Wheeler); Bomhus consimilis Cress., six 
workers having the yellow pubescence brighter than in examples 
from Garrison, N.Y.; B. fervidus Fb., one male and six workers; 
Melissodes dentiventris 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 siibgothica Haw. 
June, 1917
