94 THE CANADIAN ENTOMOLOGIST. 



should have preferred in the face of apparently so carefully made experi- 

 ments to examine first, if one of the two authors, either Dr. Adler or 

 Mr. Cameron had not determined wrongly one species of the pairs. But a 

 stronger objection against Mr. Cameron's assertion is that I possess two 

 of the four doubted pairs from the same locality. The May number of 

 the Ent. Month. Mag., just arrived, has on its first page a notice by Mr. 

 J. E. Fletcher, stating that galls made by Neuroterus numismatis proved 

 to be those of Spathegaster veskatrix. This is the third of the four pairs 

 doubted by Mr. Cameron. After all I may quote against such kind of 

 evidence the following remarks of the late Mr. B. D. Walsh in his Cynips 

 paper (p. n) : 



"I once argued in print that it was impossible that the army worm 

 moth should exist in the Eastern States, for if it did it must have been 

 found there either by Dr. Harris or by Dr. Fitch, and that scarcely had 

 the argument been printed, when it was proved by indubitable evidence 

 that it did exist." 



Mr. P. Cameron's objections against the fifth pair, Aph. radicis and 

 Andrictis noduli show simply that the German text was not understood. 



Now where are the direct and well continued observations of facts to 

 blow to the winds this theory ? I may add that the unprecedented obser- 

 vation that he put some specimens of Aphilotrix radicis in spirits for a 

 week (!) and that they revived, when taken out, would be rather difficult 

 to be repeated. 



If such facts, as given by Dr. Adler, are not to be accepted as true, I 

 think they can not be called " hypothesis or theory," but simply a fiction, 

 or in plain English, a forgery — which nobody able to understand the Ger- 

 man text will accept.

The fact that Mr. Strecker has seen fit to misstate the circumstances 

 under which this species was named has induced me to correct the impres- 

 sion he may have created as far as possible.
