46 MISCELLANEOUS COTTON INSECTS. 
doubt, therefore, as to the cause of this injury, which was quite con- 
siderable in the counties mentioned and noticeable elsewhere. 
That this is no new enemy of cotton is shown by the fact that 
Glover in his report on cotton insects in 1855 a mentions and figures 
it. Again, in his manuscript notes and plates, he states that it injures 
the plant by piercing the leaves and young shoots. b It was next men- 
tioned b} T Prof. F. M. Webster* as injuring wheat in Indiana by attack- 
ing the heads and causing them to wither. In 1893 Malty gave a brief 
description of the injury done to cotton, similar to that recently 
observed/'' 
Calocoris chenopodii, an allied species, has been observed to feed 
on larvae of the asparagus beetle in Europe, and Doctor Chittenden 
states 6 that the present species is not uncommon in asparagus beds. 
There seems to be no feasible means of combating the adult bugs; 
but the nymphs would undoubtedly succumb to a spray of kerosene 
emulsion or similar contact insecticide, which should be applied as soon 
as they are observed to be numerous. By such an application during 
July, when there are but a few here and there, serious injury by the 
increased numbers late in the summer might be prevented. 
CORIZTJS PICTIPES Stal. 
September 5, 1904, this species, which somewhat resembles the pre- 
ceding, was found very abundant in all stages at Sherman, Tex., on a 
species of Althaea, affecting it much as the leaf-bug affected cotton. 
From eggs which hatched September 5 adult bugs matured October T. 
Later in October the species was found on cotton at Terrell, and 
specimens taken on cotton were received from Cameron, La., Octo- 
ber 10. 
OTHER PLANT-BUGS. 
The black spots upon the bolls and the consequent shrinking and 
softening are not always due to Calo<-<n'is ,-<ij>/(lus Say, as several 
other species have been noticed as producing the same injury, although 
the}^ do not occur in such large numbers and the injury is not so 
general. 
largus succixctus Linn. 
This species is frequently found on the bolls in late summer, 
causing some injury. Adults were found common late in July, and 
on the 28th a pair were confined on cowpeas. On August 6 two egg
