atures of +15°, 0.0°, -10°, -20°, and -—25° F.," according to a report 
submitted by D. W. Jones. "Comparatively short periods of exposure are 
fatal at and below -10° F., but at 0.0° F. and at +15° F. the larvae 
exhibit greater resistance, due apparently to a low freezing point of 
some body constituent other than water. * * * Establishment of these 
periods of lethal exposure has a direct application to commercial process-— 
ing of green sweet corn and provides a guide for sterilization by means 
of cold." 
_. T. BE. Holloway, of the Sugarcane moth borer project at New Or- 
leans, La., reports that "a search has nearly been completed," by him- 
self, W. E.. Haley, and H. A. Jaynes "for the parasites from Peru released 
during the summer. Recoveries have been made at two plantations. At. 
one place a moth borer larva which had evidently been parasitized by the 
fly Paratheresia claripalpis V. da. W. was found. At another plantation 
nine empty cocoons of the wasp Ipobraon rimac Wolcott were discovered. 
The two parasites from Peru have therefore lived for at least one gener— 
ation under Louisiana field conditions." 
H. L. Parker, of the European Parasite Laboratory, Hyéres, Var, 
France, says that a weevil "being parasitized by Exeristes roborator 
Fab. has now been identified by Charles Fagniez as Larinus longirostris 
Gyll. Although A. Hustache in his "Curculionidae Gallo-Rhenans" lists 
‘Larinus lenzae G. W. Fabre and L. stoehelinae Bed. as hosts of this 
parasite, this is the first record of its being found on L, longirostris. 
In each case the pupal stage was the one attacked." 
According to E. V. Walter of the San Antonio, Texas, laboratory, 
he found the sorghum midge (Contarinia sorghicola Coq.) plentiful in the 
El Paso,. Tex., region (elevation about 3,500 feet) this year as well as 
in other places far beyond its previously known western limits. Two of 
the localities recorded are beyond the 105th meridian and Mr. Walter says: 
"This is the first record we have of the sorghum midge being found west 
of approximately the 100th meridian or above an elevation of approximately 
2,000 feet." 
J. C. Frankenfeld, Tempe, Ariz., says. that "a parasite of the 
genus Chalcis, which is likely Chalcis ovata Say, since that was reared 
during the years 1913-14 from the pupa of the range caterpillar (Hemileuca 
Oliviae Ckll.), is parasitizing many pupae of the species this season." 


COTTON INSECTS 
Airplane collection of insects has been continued at Tallulah, La. 
P. A. Glick, J. M. Yeates, and assistant report: "Twenty-seven flights 
were made during the month of October * * * using a total of 22 hours and 
25 minutes, in the exposure of the screens. * * * A total of 525 insects 
were collected at the following altitudes (with the number of insects ta- 
ken given in parenthesis): 200 feet (249), 1,000 feet (111), 2,000 feet
