March and were' general in cotton fields by the end of April. By June hoppers 
could "be found in some fields at the rate .of . 2S, per 100 plants and the aver- 
age remained about that number during June, though it was heavier in some 
fields, Daring the latter part of June dusting was done on four plantations 
in the vicinity of College Station. The hoppers were decreasing rapidly by 
July 13. In Arkansas and Oklahoma there were sorre reports of cotton-hopper 
injury. In Louisiana and Mississippi these insects were also present in the 
cotton fields, but other mirids, Lygus prat ens is L. , and Adelohocoris 
ra'oidus Say, cr.used more damage to cotton. The cotton flea hopper occurs 
in practically all areas where cotton is grown. This year for the first time 
it was recorded definitely as .a cotton pest of importance in Arizona, although 
another mirid, Ly^us elisus he s per jus- Knight , was more abundant and caused 
more damage in that State. ,(JR. W. Earned, 3ureau of Entomology and Plant

STINKBUGS 
Four species belonging to the family Pentatomidae, namely, Suschis - 
tus iimictiventris Stahl, Chlorochroa sayi Stahl, Thyanta custator Fab. , 
and C. ligata Say, did considerable damage to cottun during the summer and 
fall of 1935 i n irrigated sections of the Southwest. These insects, by 
virtue of their boll-puncturing habits, are responsible for lint stains 
that lower the grade of cotton a.nd they may also cause shedding of smaller 
bolls and the production of inferior lint on pierced seeds within the boll. 
In Arizona E. impictiventris was decidedly the most important species with 
respect to abundance and amount of Injury, with C. sayi and I. custato r 
following closely in the order named. C. li;~ata was numerous in only a. few 
fields in Graham County, As a rule, however, it was 01 no importance. As 
shown by the internal cell proliferations formed about puncture wounds, the 
percentage of injured bolls in 1$35 in Arizona was 27.2 percent, as compared 
with 23.U percent injured bolls noted in I93U. In the vicinity of Presidio, 
Tex., pentatomid injury to cotton was also severe, C. ligata , C_. sayi i and 
T. custator being the insects concerned. By the end of August, 33.3 percent 
of the bolls 35 days old had been damaged, 23.7 percent of them severely. 
Unverified reports from the San Joaquin Valley of California indicate that 
pentatomids were severely injuring cotton bolls in that area during 1935*
