16 BULLETIN 250, U. S. DEPARTMENT OF AGRICULTURE. 
In the trays, both at Worcester and Melrose Highlands, larvz started in the 
first stage died on or before reaching the third stage. 
AMERICAN HORNBEAM (Carpinus caroliniana Walt.). 
All larval stages feed upon this foliage, and defoliation results in badly 
infested territory. 
This species was tried in both laboratories, and first-stage larve died on or 
before reaching the third stage. 
Hop HornBEAM (Ostrye virginiena [Mill.] Willd.). 
In the tray experiments at Melrose Highlands and Worcester first-stage larve 
failed to develop beyond the third stage on this foliage. 
Larve feed on this foliage in all stages in the field.’ 
HIGHBUSH HUCKLEBERRY (Géylussacia baccata [Wang.] Koch). 
This is an unfavored food plant and will not sustain the larve until they are 
full grown. The observers report seeing the larve in all stages feeding upon 
this species; in most cases they were probably larve that had spun down from 
overhanging trees. : 
In the trays a few male moths were obtained from larve started in the second 
stage. 
INKBERRY (Ilex glabra [L.] A. Gray). 
In southeastern Massachusetts this species is common over large areas. 
Tray experiments and field observations both show that the larve can not 
subsist upon it. 
SMooTH WINTERBERRY (Ilex levigata [Pursh] A. Gray). 
Larve have been reported on this species in ail stages eating small holes or 
notches in the leaves. These were probably larve that had been shaken down 
from overhanging trees or had crawled from near-by species. None seemed to 
stay for extended feeding. 
In the trays there was very slight feeding and no growth. The caterpillars 
died rapidly of starvation. 
AMERICAN WHITE Horry (Jlex opaca Ait.). 
Mr. Schaffner reports finding larvz in the third, fourth, and fifth stages feed- 
ing slowly on this species. 
Larvee in the trays fed sparingly in the first stage, but died rapidly of starva- 
tion. In the succeeding stages there was hardly any feeding, and death resulted. 
FEVERBUSH (llex verticillata [L.] A. Gray). 
Tray experiments and field observations show that gipsy-moth larve will not 
- subsist on this species. A few small notches in the leaves observed in the field 
and notches and small holes in the leaves in the trays constituted all the feed- 
ing. Larve died rapidly and did not grow at all. 
LARGER BLUE-FLAG {Jris versicolor L.). 
Mr. Kennedy found fourth and fifth stage larve feeding on this species in 
Hampton, N. H. The swamp was situated near a group of gray birches that 
were badly stripped; the larve were being blown off by the wind, and in search- 
ing for food crawled to these plants and partially defoliated them.
