reported after June. We are informed that in some localities this 

 insect has been injurious for some years, while elsewhere this seems 

 to have been the first season in which it has been noticed. It is a 

 common pest of cowpeas and other legumes. 



The white-lined morning sphinx (Deilephila lineata Fab.) always 

 does more or less damage to young cotton in weedy fields. This year 

 these larvae appeared in extraordinary numbers near San Antonio and 

 destroyed not only cotton but all sorts of garden truck. 



The garden web worm (Loxostege similalis Guen.) did serious injury 

 to young cotton in southwest and north Texas and Oklahoma, caus- 

 ing replanting in man} T instances. The common name ' ' careless worm " 

 used by the planters is peculiarly applicable to this pest, as it increases 

 and becomes injurious only where the careless weeds (Amaranfihus 

 spp.) are allowed to grow, and can easily be controlled by spraying or 

 dusting. 



In southwest Texas the large lubber grasshopper (Braehypeplus 

 magnus) usually destroys a considerable amount of cotton. The hop- 

 pers occur in large numbers and go through a field, cutting off all the 

 cotton in their path. 



Likewise Laclinosterna lanceolata Say often occurs in large swarms 

 and cuts off the young plants on considerable areas. 



PECAN INSECTS. 



The growing of pecans is becoming a very profitable industry in 

 Texas, though its development has only commenced. 



The worst pest yet brought to my attention is the pecan husk worm 

 (Acrobasis caryce Grote). The larva? bore into the } 7 oung pecans, 

 hollowing them out and causing them to drop to the ground. Later 

 they riddle the husk and channel the surface of the nut. This spe- 

 cies occurs on pecans where they grow in Texas, and, according to 

 Doctor Dyar, in Illinois, Massachusetts, and New York. It is reported 

 to sometimes almost totally destro}^ the crop in localities and to do 

 serious injury generally in west central Texas, the chief pecan section. 

 Usually injury is most between May 20 and June 10. This year the 

 pest did comparatively little damage and no moths emerged until 

 Jul} 7 9. This was largely due to hymenopterous parasites. No means 

 of practical control have yet been ascertained. 



Phylloxera sp. has been sent me as injurious to pecan foliage near 

 Galveston, and I find it common on the campus at the college. 



The fall webworm is frequentty injurious to pecan trees and this 

 season did much damage to fruit trees in south Texas. A similar 

 webworm, but of uniform brown color, which we have not deter- 

 mined, but either another species of Hyphantria or a variety of the 

 above, seems to be peculiarly a pecan insect.
