INSECTS ATTACKING MAN AND DOMESTIC ANIMALS 
HAN 
CHIGGERS ( Trnmb.id5.ua spp.) 
J. A. Hyslcp $July 25). "Chiggers are much more prevalent than they 
were last ysar in southern Montgomery County. The summer has been 
extremely wet ," 
F. C. Bishopp (July 27). "T7ith the coming of hot, dry weather during 
the latter part of June and July the unusual abundance of chiggers 
rapidly decreased." 
CATTL E 
SPINOSE EAR TICK ( Ornithodoros megnini Duges) 
F. C. Bishopp (June 26). "The writer and D. C. Parman found the ear 
tick causi.ig considerable annoyance in Uvalde County during June. 
Stockmen say it is much more abundant than usual." 
SCKEW-WGBM ( Chrvsomva macellaria Fab.) 
F. C. Bishopp (July 27). "After about July 10 screw-worm cases, which 
had been rather more numerous than normal in southwestern Texas, began 
to subside materially. On this date Mr. D. C. Parman reports com- 
paratively few cases emong cattle in the vicinity of Uvalde. This is 
undoubtedly associated with the hot, dry weather." 
HORNFLY ( Haematobia irritans L . ) 
F. C. Bishopp (July 27). "During May and the greater part of June 
hornflies were a pest of much importance throughout practically all 
of Texas. About the middle of Juno they began to decrease materially 
and there was noted in some sections a tremendous increase in the 
number of tumblebugs , especially C anthon vig 1 1 ans . In places these 
were so numerous as to completely break up the dung within a few hours 
after it was dropped. These beetles and the hot, dry weather are 
probably responsible for the falling off in the number of flies ." 
SHEEP 
BLACK ELOWLY (Phorroia regina Meig.) 
F. C. Bishopp (July 27). "This fly has practically disappeared in 
Texas. It was extremely numerous and caused heavy loss among sheep 
raisers in the western part of the State during the spring."
