THE ANGOUMOIS GRAIN MOTH IN PENNSYLVANIA. 



This well-known pest to stored grain is found commonly tlirough 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, Onr 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 RodoUa iceryw. 

 This insect has done much effective work in the eastern provinces and 

 has been recently carried to the w^estern 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. 



In Bulletin No. XI of the Cornell University Agricultural Experiment 

 Station, Prof. J. H. Comstock reports the Wheat Saw-fly {Cephus pyg- 

 mceus L.) 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. ii, 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 tweuty 

 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 single 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.
