PLANT-BUGS INJURIOUS TO COTTON BOLLS. 
(Anasa tristis DeG.) by Doctor Ashmead in 1886. During the sum- 
mer of that year it was found in Florida that about 30 per cent of the 
eggs of Anasa tristis were parasitized by this insect. A closely 
related Proctotrypid has been reared by Ashmead from the eggs of 
AcantlwcepJiala (Metapodius) femorata Fab. 
A Tachinid fly, Trichopoda pennipes (fig. 22), has been reared from 
Leptoglossus oppositus. Doctor Chittenden a states that eggs of this 
fly were frequently noted, attached to the thorax of adults of this bug, 
in the vicinity of Washington, D. C, in 1901. The fly has previously 
been reared from adults of the 
squash-bug. It occurs in Texas, 
Mississippi, Florida, and in prob- 
ably all of the cotton-growing 
States. It seems to be of little 
consequence as a natural check to 
the leaf-footed plant-bugs in 
Texas, for among 58 specimens 
of L. phyllopus and 24 specimens 
of L. oppositus in the collection 
of the Bureau of Entomology at 
the laboratory at Dallas, Tex., 
only a single specimen of the lat- 
ter species bore a Tachinid egg. 
This was attached to the upper 
surface of the head of an adult male specimen collected by Mr. F. C. 
Bishopp at Paris, Tex., on August 26, 1905. 
INSECTS OF THE LEAF-BUG FAMILY (CAPSIDiE) INJURIOUS TO 
COTTON. 
Thus far the only species of the family Capsidse which has proved 
itself of importance as a cotton pest is the cotton leaf -bug (Calocoris 
rapidus Say, fig. 23). This species was first mentioned in this con- 
nection by Townend Glover b in 1856. It is widely distributed in 
North America and is found in all the cotton-growing States. Prac- 
tically all that is known concerning the life history and habits of this 
insect is presented by Sanderson in a report of observations made in 
1904. Investigations thus far have not revealed any practical 
method of combating the adult bugs, although destruction of nymphs 
by a spray of kerosene emulsion may be advisable under some cir- 
cumstances. The practicability of attracting the adults to light has 
not been thoroughly tested. Hon. J. D. Mitchell, of Victoria, Tex., 
captured 165 specimens by the use of 3 trap lanterns in a cotton
