NATUKAL ENEMIES OF COBEIDS. 91 
Leptoglossus zonatus Dall. 
Leptoglossus zonatus was observed by the writer to be fairly 
numerous in cotton fields at Tlahualilo, Durango, Mexico, in Sep- 
tember, 1904, but in the same locality, in July, 1905, not a specimen 
was found although cotton fields were visited daily during the month. 
It is not likely that this bug will ever become common in cotton fields 
in this country except possibly in certain districts in the semiarid 
region of western Texas. 
OTHER COREIDS KNOWN TO ATTACK COTTON. 
In the Agricultural Report for 1855, Glover mentioned Acaniho- 
cephala femorata a (PL I, fig. 5) as an insect frequently found in cotton 
fields in Florida. Professor Comstock b in his Report on Cotton 
Insects, 1879, quotes from a statement by Mr.W.Trelease, to the effect 
that these bugs were several times observed to catch and suck the 
juices from the bodies of cotton caterpillars, Alabama (AU tia argiHaa a 
Hbn. It was consequently concluded that at that time the knowl- 
edge concerning the habits of the bug favored its being considered a 
friend of the cotton grower. Ashmead c stated in regard to this species 
as observed by him in Mississippi in 1893 that it was •captured 
several times puncturing young bolls and while not especially numer- 
ous does considerable damage." 
The flat-horned Coreid (Ohariesterus antennator Fab. is recorded 
by Ashmead as common in cotton fields in Mississippi. Prof. E. D. 
Sanderson** has given brief notes on two species. Corizus pictipes 
Stal and Jadera lisematoloma Il.Schf., which are frequently found on 
cotton, although by themselves not in sufficient numbers to do appre- 
ciable damage. In addition to the above-mentioned species 
Coreids the writer has occasionally found on cotton a strikingly 
marked bug, Hypselonotus fulvus DeG., which may appropriately be 
known as the banded-legged Coreid. This insect occurs commonly 
in southwestern Texas, but is not usually found on cultivated plants. 
NATURAL ENEMIES OF COBEIDS DESTRUCTIVE TO COTTON. 
Mr. R. C. Howell, formerly a field agent of this Bureau, collected, 
on August 15 at Sulphur Springs, Tex., a batch of 42 eggs o[ a species 
of Leptoglossus, which had been deposited on the bract of a cot- 
ton square. From these eggs •'! Proctotrypid parasites emerged, 
which Doctor Ashmead determined as Uadronotus anasa Ashm. 
This parasite was first reared from the eggs o( the squash-bug
