covered with winter eggs. I watched them carefully', not only by means 

 of those brought with me from England, but of others brought from 

 New York in the late fall or early winter, and still other specimens re- 

 peatedly received during the winter from Eichfleld Springs. As the 

 hatching period approached I was quite surprised to find how many of 

 the eggs shriveled up and perished. I also made it a point to be on 

 the spot as soon as vegetation began at Richfield Springs, and found 

 there, in a state of nature, the same mortality among the eggs. The 

 large majority of them that had escaped natural enemies had perished 

 by shrinking and shriveling. Again, the stem-mothers, which hatched 

 on Plum last spring, though they were few compared with the number 

 of eggs that had been provided, were for the most part lost through 

 storms or the working of natural enemies, so that a very small propor- 

 tion succeeded in developing. A number of additional interesting 

 details of an entomological character have been obtained since the last 

 meeting of the society, but they will be brought together in a forth- 

 coming report from the Department of Agriculture. 



The whole record has been rendered the more difficult by virtue of 

 the occurrence of a very closely allied species {Phorodon mahaleb)^ 

 which, though hatching at the same time as, and very similar to, huninli, 

 does not migrate to the Hop, but goes to various other plants of no 

 importance in cultivation. 



LIFE-HISTORY OF GRAPTODERA FOLIACEA Lee. 



BY MARY E. MURTFELDT. 



In Bulletin No. 3 of the Kansas Experiment Station Professor Po- 

 penoe has a very interesting illustrated article on what he denominates 

 "A New Apple Insect." This paper was the more interesting to me 

 inasmuch as it anticipated — in the matter of publication — certain ob- 

 servations of my own on the same species. 



About the 1st of June of the present year a correspondent sent me, 

 from Colorado, a package containing a dozen specimens of a fieabeetle, 

 closely resembling in size and form the Grape-vine Flea-beetle [Grnpto. 

 dera chalybea, Illig.), but (littering in color, being of a highly polished 

 metallic green instead of blue. The apple leaves inclosed with these 

 specimens were riddled with small, irregular perforations, and I was 

 informed that these leaves correctly represented the condition of the 

 foliage of most of the young trees in an extensive nursery — that of the 

 Stark Bros., near Denver, Colo. 



As the species was unknown to me, I inclosed specimens to Professor 

 Eiley, who kindly determined them for me as the species under con- 

 sideration. Professor Riley informed me that he had observed the work 

 of the beetle and its larva in Missouri in 18712 feeding upon Hawthorn; 

 also in 1877 in Colorado, and had published a brief account of it and its
