THE ANGOUMOIS GRAIN MOTH IN PENNSYLVANIA. 
This well-known pest to stored grain is found commonly through the 
Southern States laying its eggs in corn before harvest, but has hereto- 
fore been known only in granaries in the North. Recent communica- 
tions, however, from Pennsylvania and New Jersey, near Philadelphia, 
indicate that where wheat is stacked in the field and left until fall and 
winter before threshing, the moths oviposit in it abundantly and in 
some places have done serious damage. The probabilities are that this 
habit originated in some wheat field in the vicinity of a large granary, 
the moths flying out from the building in late summer to the wheat 
stacks in the field, which afforded exceedingly appropriate places for 
egg-laying. Our correspondents inform us that when the wheat is 
threshed soon after harvest it does not become infested, so that by fol- 
lowing this course and occasionally spraying the storage places in the 
spring with kerosene or kerosene emulsion all danger may be averted. 
THE SOUTH AFRICAN LADYBIRD ENEMY OF ICERYA. 
We mentioned in our 1886 report the fact of the occurrence in Cape 
Colony of a native ladybird which feeds extensively upon the Fluted 
Scale, and which was named by the late E. W. Jansen Rodolia icerye. 
This insect has done much effective work in the eastern provinces and 
has been recently carried to the western provinces and colonized under 
glass in the hope that it will be acclimatized there. The experiment from 
latest accounts seems to be a success. 
ON THE DATE OF THE INTRODUCTION OF THE EUROPEAN WHEAT 
SAW-FLY. 
Tn Bulletin No. XI of the Cornell University Agricultural Experiment 
Station, Prof. J. H. Comstock reports the Wheat Saw-fly (Cephus pyg- 
meus Li.) as having first been observed at Ithaca, N. Y., in 1887, this 
being the first published record of the occurrence of the insect in this 
country. Further records are published in INSECT LIFE, Vol. 11, p. 286, 
viz, its occurrence in Canada in 1887, and at Buffalo, N. Y., in 1888. 
Other imported pests that might be mentioned are known to have 
been present in limited numbers and restricted localities for twenty 
years and more before attaining economic importance, and. since at the 
time of the publication of this bulletin (November, 1889) the insect had 
become rather abundant, it might be assumed that it was introduced 
quite a number of years earlier. A singie specimen was taken by me 
at Ithaca, but unfortunately the exact date of capture was not noted. 
I am inclined to believe, however, that this specimen was found about 
1881 or 1882, and am positive that it was not taken later than 1884, 
and possibly as early as 1878 or 1879.—F. H. CHITTENDEN.
