Subtropical leafhopper a pest in Washington, D. C., greenhouse.— 
W. H, Larrimer, Arlington Farm, Va., reports as follows: "With fur- 
ther reference to the eccurrence. of Peregrinus maidis (Ashm.), ina. 
greenhouse at Columbia, Mo., as reported in the. February Monthly Letter 
of the Bureau of Entomology by P. W. Omanof the Division of Identi- 
fication and Classification of Insects, ‘FF. We Poos reports that he 
found this species breeding abundantly in May 1928 on teosinte ina 
greenhouse of the Department in Washington. Spraying was necessary’ 
in order to prevent destruction of the plants by this species, speca— 
mens of which are still available. The identification of this mater 
ial was verified sh Dr. Herbert Osborn, t 
Armyworm overwinters successfully; army cutworm moderately abun- 
dant in alfalfa.--H. H. Walden, Wichita, Kans., reports the occurrence 
of the armyworm (Cirphis unipuncta Haw.) on March 16, at the average 
rate of 10 larvae per clump of volunteer wheat examined. All were 
in the larval stage, 33 percent being in the fourth instar, 55 per- — 
cent in the fifth instar, and the remainder in the last (sixth or 
seventh) instar. This indicates successful wintering for this species 
in the Wichita area and suggests possible outbreaks later in the | 
season, although there is some parasitization, 4 percent yielding 
parasites up to March 30. The army cutworm (Chorizagrotis auxiliaris 
Grote) was-moderately abundant in a few fall-sown alfalfa fields dur- 
ing March and has been reported in the press as being responsible for 
damage to alfalfa probably caused mainly by the corn ear worm (Helio- 
this obsoleta Fab.), which extensively injured young alfalfa in the 
fall of 1933. Mortality in army cutworms collected about the middle 
of March has been 13 percent from parasites and 25 percent from dis- 
ease, 
Grass hosts of Hessian fly reflect general scarcity of fall- . 
generation fly.--According to E. T. Jones and J. R. Horton, Wichita, 
examination of 7,995 culms of 5 species of grass ordinarily infested 
by the hessian fly collected in wheat fields during March did not 
yield a single infested stem. Examination of about half as much 
material of these same 5 species of grass last year yielded substan~- 
tial infestations in every one. This suggests the possibility that 
these grasses either were not available or were not suitable for 
oviposition when the bulk of the flies emerged in the fall of 1933. 
This es alt ak? he should be investigated, 
Chinch bug th igrating from volunteer wheat.--W. T. Emery, Wichita, 
reports that a continued study of Blissus leucopterus Say in winter 
quarters during March indicated that there was a gradual thinning 
out of the bugs in clumps of volunteer wheat, ‘whereas there was no 
shift in the population in Andropogon sod. Temperatures taken in the
