witli negative results. Practically .all of the cotton acreage in the 
district will "be covered "by this method of inspection in another month. 
One of the new gin trash machines mounted on a truck was sent to 
the Lower Rio Grande Valley of Texas on July 24. Other machines were 
sent out as they were completed, so that by the end of July there were 
five machines operating in the above area. These machines inspected 
2652 "bushels of trash from 25 gins with negative results. 
MEXICAN FRUIT FLY (Anastrepha ludens Loew) 
As a supplement to the inspection work this summer, 1,077 fly traps 
similar to those/in Florida were placed in 118 selected groves during the 
first part of July. The use of these traps resulted in the taking of 
one adult Anastrepha (not ludens ) , July 14, in a grove one mile south of 
Mission, Tex. Additional traps placed in this and the surrounding groves 
gave negative results the remainder of the month. 
Adult flies continue to be taken in the traps in Matamoros. During 
the month 176 traps were maintained in 57 different premises scattered 
throughout the city. The use of these traps resulted in the taking of 
30 adult flies on 13 different premises. Of interest in this connection 
is the fact that in only 4 of these premises were reinf'e stations found. 
All trees within an area of four blocks around each point of infestation 
were sprayed at weekly intervals with poison-bait spray. 
OUTSTANDING ENTOMOLOGICAL FEATURES IN MEXICO, SUMMER OP 1931. 
Alfonso Dampf , Head of Department of Research 
Officina Federal para la Defensa Agricola, San Jacinto, D. F. (Mexico) 
The extraordinarily heavy rains which fell in June and July in 
Mexico had very interesting effects on insect pests. There v/as an un- 
precedented outbreak of cutworms, not only in the central highland but 
also in the tropical parts. Reports were received from the States of 
San Luis Potosi, Michoacan, Hidalgo, Mexico, Puebla, Guanajuato, Morelos, 
Veracruz, Guerrero, Oaxaca and Chiapas. The species most destructive 
to alfalfa proved to be Copitarsia con sue ta Wlk.,a noctuid known as a 
potato pest, a borer of cabbage heads, and an enemy of tobacco plants. 
(Dampf det.) 
Another surprise was the appearance of the chinch bug, Blissus 
leucopterus Say, in the Ixtlahuaca Valley, State of Mexico, 400 meters 
a"bove sea level, as a serious pest of corn, the first case since the 
establishment of an organized plant protection service in Mexico. Corn 
planted in June was without exception badly attacked; fields planted in 
April looked healthy. The pest eerie from the winter-wheat fields and 
is apparently at home in the tussocks of alpine grass in the nearby 
hills and mountains. E. G. Barber, U. S. Bureau of Entomology, identified
