as to just what has happened to the other parasites which were so abun 
dant on the midge before the appearance of Eupelmus popa in this section. 
Only one other parasite, Tetrastichus sp., has been found in the five 
years since I came to San Antonio and that species Only one season and 
in extremely small numbers. Eupelmus popa is an external parasite while 
the others are internal parasites. In case Eupelmus popa does not find 
enough midge to complete its development it will attack the kernel it- 
self. Considering these habits it is possible that Eupelmus popa has de— 
stroyed the other parasites while doing very effective work against the 
midge, although it would hardly seem possible for it to cause such com— 
plete elimination of the other parasites." 
Mr. Walter also reports observations on the harvester ant (Pogo~ 
nomyrmex barbatus F. Smith). He says: "The female in my observation 
cage died on November 6. This made 126 days she was kept in the obser-— 
vation cage. During this time she did not come out of her nest to se- 
cure food nor was there any evidence that any food was carried into the 
nest from outside. During this time seven young were reared from a to— 
tal of 62 eggs found near the beginning of the period under which she 
was under observation. A number of eggs were deposited at later dates 
but it is impossible to give the total number of eggs deposited since 
there was a constant turn-over in eggs deposited and eggs eaten. It 
was observed that both adult and young are cannibalistic and feed on 
the younger larvae and eggs. The queen was observed eating one of 
the eggs and she was observed to feed eggs to the larvae." 
J. C. Frankenfeld completed the fall collection of egg masses of 
the range caterpillar (Hemileuca oliviae Ckll.) and returned to the 
Tempe, Ariz., laboratory November 24. His report includes the fol- 
lowing statement: "In two areas, one near Miami, New Mex., about 6 
miles west of Springer, and the other at Nolan, New Mex., about 5 miles 
southwest of Colmor, considerable parasitism of Hemileuca oliviae pupae 
occurred this season. It is impossible to make a count on the percent= 
age of parasitism but a conservative estimate would approximate 30 per 
cent. The parasite is without a question Chalcis ovata Say, a common 
pupal parasite in the Southwest. Occasional parasitized pupae could be 
found in almost every locality in the infested area visited, but in only 
these two were they numerous enough to be of any importance." 


Mr. Frankenfeld also states that "in areas where liberation of 
Anastatus semiflavidus Gahan were made last year adult parasites were 
observed parasitizing host eggs. As late as November 20 these para— 
Sites were found to be active, although several severe frosts had oc-— 
curred prior to this date."
