Prof. W. P. Brooks found it abundant at Sapporo in Japan in 1883, 

 where it fed upou strawberry in addition to other plants. In Massa- 

 chusetts it is reported as feeding upon the leaves of Apple, Cherrj', 

 Quince, Elm, Linden, Maple, Balm of Gilead, Birch, Oak, Willow, Wis- 

 taria, Norway Spruce, and Corn. Professor Fernald states that in this 



country it occurs only in Medford, Mass., 

 where it occupies an area in the form of 

 an ellipse about IJ miles long by one- 

 half mile wide. We have just learned, 

 however, from Mr. Lewis E. Hood, of 

 Somerville, that it was observed in that 

 town last summer. The instance men- 

 tioned in Insect Life, Vol. II, p. 8G, 

 of its occurrence at Winchester is still 

 uncertain, as only j)artly grown larvae 

 were sent by our correspondent, Mrs. 

 Holt. 



Kegarding its natural enemies. Pro- 

 fessor Fernald states that none have 

 been noticed in this country, but that 

 eleven species of Ichneumonidce and 

 seven species of Tachina flies have been 

 noticed in Europe. This statement is 

 evidently taken from Ratzeburg, who 

 mentions this precise number of eleven 

 Hymenopterous parasites (not all Ich- 

 neumonidse, by the way). By means, however, of a manuscript cata- 

 logue of the relations of parasitic Hymenoptera, which Mr. Howard has 

 in preparation, we are able to more than double this list, and as a mat- 

 ter of general interest we publish the following :
