24 MISCELLANEOUS COTTON INSECTS. 



in numbers by the remedial measure.s talven and by birds that they 

 were not excessively abundant; but had the cultures been effective 

 some diseased individuals would surely have been found three weeks 

 after the first distribution, when the insects were still plentiful. Fur- 

 thermore, at College Station, on April 4, a dozen locusts were dipped 

 in the culture received from Professor Bnmer and introduced into a 

 field cage where several dozen live hoppers were given favorable con- 

 ditions. These were supplied with f()o<l and the cage kept in good 

 condition until June 4, during which time nuich rain fell, but no dis- 

 eased specimens were observed. 



Early in June cultures of the South African fungus were received 

 direct, through the courtesy of Dr. Alexander Edington. Upon learu- 

 ing of an outbreak of 3J. differential is in north Texas, and upon the 

 request of planters there, several of these tubes were sent them and 

 were prepared and disseminated bA' them as directed. They were, 

 however, unable to notice any diseased locusts as a result. 



These accounts of failures to secure any benefit from grasshopper 

 cultures can not be regarded as at all conclusive concerning their lack of 

 efficacy, but they at least add to the weighty evidence already reported 

 against the value of such cultures for the control of grasshoppers. 



THE CLUMSY LOCUST.

Throughout the counties of west-central Texas, as far east as Bexar 

 and Comal, this species replaces the common southern lubber grass- 

 hopper {/>/<'%fyy>/|'v■'^s• refiriilafiis Thunb.), shown in figure 13. Unlike

the latter species, liowever, the '"clumsy locust"* occurs m large num- 

 bers and often does serious damage. In 1H04 it was much less injuri- 

 ous than usual, and no observations upon it in the field were possible. 

 Our information concerning its habits is, therefore, derived mostly 

 from correspondence with Mr. L. B. Smith, of Rescue, Lampasas 

 County, a prominent bee keeper and careful ol)server, whose accounts 

 have been largely confirmed by others in neighboring counties. May 

 22, 1903, Mr. Smith wrote as follows: 



We are being bothered again l)y the wingless locusts. They are destroying the 

 cotton crops by the wholesale, and, iniHke most other insects, these come early and
