88 PLANT-BUGS INJURIOUS TO COTTON BOLLS. 
INSECTS OF THE SQUASH-BUG FAMILY (COREID^ INJURIOUS 
TO COTTON. 
THE LEAF-FOOTED PLANT-BUGS. 
(Leptoglossus phyllopus L., L. oppositus Say, and L. zonatus Dall.) 
A review of the economic status of the northern leaf-footed plant- 
bug {Leptoglossus oppositus Say) and the banded leaf-footed plant- 
bug {Leptoglossus phyllopus L.) was presented by Dr. F. H. Chittenden 
in an early bulletin of this series. a In a later bulletin a more ex- 
tended account of the former species, including description of all 
the immature stages and observations on the life history and habits, 
was given b}^ the same author. h Both of these species are com- 
monly found in greater or less abundance in cotton fields throughout 
the various cotton-growing States. L. zonatus Dall. is of compara- 
tively rare occurrence in the United States, and probably for this 
reason no record of its attacking cotton 
in this country is available, although 
the author has noted its injury to cot- 
ton bolls in Mexico, where it is more 
abundant. c 
Leptoglossus phyllopus L. 
Leptoglossus pJiyllopus (PI. I, fig. 6; 
text fig. 19) is the most common species 
of the leaf-footed plant-bugs found in 
cotton fields. Doctor Chittenden has 
recorded its principal cultivated food 
plants, showing it to be an almost om- 
nivorous plant feeder and one likely 
piant-bug (Lepto- to cause serious local damage to many

mead, m recording his observations 
made in July, 1893/* mentioned the insect as of common occurrence 
in cotton fields in Mississippi, sometimes as many as 3 or 4 together 
being observed on a single boll. 
About 20 adults of this species were observed by the writer on a 
single cotton plant near Mason, Tex., on October 20, 1905. They 
began to take wing when the writer was quietly watching from a 
distance of several feet and in less than a minute only 2 or 3 speci- 
mens remained. On the whole, however, these bugs were not 
very numerous in the locality named, not exceeding, on the average,
