40 THE CANADIAN ENTOMOLOGIST. 



Dear Sir, — 



Having been requested some years ago by Prof. Just, of Carlsruhe, to 

 co-operate in the annual botanical review, I have now agreed to take upon 

 myself the preparation of a report in reference to those vegetable excres- 

 ences known as galls, produced by insects. 



The greatest difficulty in this work arises from the fact that the litera- 

 ture treating on the subject is scattered throughout a great number of 

 works and various journals, of which we find only a part in our libraries ; 

 also, those which we possess, and particularly the later publications, are 

 often of difficult access. It is therefore quite impossible to write a com- 

 plete report if the editors do not send us the various papers which issue 

 from the press You or your readers will oblige me greatly by sending 

 copies of any writings in reference to galls which have appeared since 

 1875, as well as those which may be published from time to time. Parties 

 sending extracts from journals will please add the date of publication. As 

 an equivalent I shall be happy to send to any one helping me copies ot 

 my own writings on this subject. Dr. F. A. W. Thomas.

I have the pleasure of noting the capture, June 23rd, of a fine speci- 

 men of the very rare Geometrid, Eubyja qucrnaria Smith & Abb. ; it was 

 taken resting on the trunk of a Hickory tree. Early in September I took 

 sixteen specimens of Aspilates Lintneraria Pack., among which were 

 several perfect examples of the female. It is an exceedingly variable 

 species, scarcely two specimens being alike. The females were submitted 

 to Dr. Packard, who determined them as the liberaria of Walker.

I have found Melitaea phaeton in large numbers this season in a large 

 swamp on the east side of Mt. Tom, four miles from Holyoke ; also M. 

 Harrisii in the same locality. Since the middle of August up to the 

 present time I have found over 300 larvae of Deikphila lineata feeding on 

 Purslane. They seem to be very plentiful this year ; never found but a 

 few before. Joseph E. Chase.
