TilE CANADIAN ENTOMOLOGIST. oo 



There sliould be between loo and 130 species of Odonaia fuund in 

 Ontario. 'I'hey liave been but litde studied here. Dr. E. j\I. Walker, of 

 Toronto, lias probably done more work upon this !2;roup than anyone else, 

 and I am glad to know that he will likely soon jHiblish in this journal a 

 list of the species wliich he has observed. During the coming season, 

 which will not be far distant when this article appears, let us hope that our 

 Ontario collectors, at least, will give more attention to this interesting group. 



WHAT EUCHCECA COMPTARIA, WALK., REALLY LS. 



BY RICHARD F. PEARSALL, BROOKLYN, N. Y. 



My last paper, upholding Dr. Hulst's determination that £. 

 perlineata. Pack., is the above species, was intended also to convey the 

 idea that until we knew positively that he was wrong it was belter to 

 accept his decision. Nor was it my desire to belittle the judgment of 

 AL'. Prout, as I expressly stated. Immediately after its publication I 

 received two letters from .Mr. Prout, explaining his views so clearly that I 

 began to doubt the correctness of my opinion, as set forth in my j^aper 

 upon " The Genus Venusia and Its Included Species."^ It must be noted 

 that up to that lime none of us had seen Dr. Packard's types. In the 

 paper last named I mentioned that couiptaria, Walk. ( =per/ineata, Pack.) 

 was taken plentifully by me in the Catskill Mts., and I proceeded there- 

 fore to describe another eastern form under the name of salienta., associ- 

 ating with it a larger Californian species, which my scant material did not 

 warrant me in separating, Later,^ with the receipt of a larger series, I 

 had about determined that it was entitled to specific rank, and that 

 opinion I now hold. Convinced that Mr. Prout would be able to judge 

 correctly, I forwarded to him examples of what I called comptaria, Walk. 

 [=per/i?ieata, Pack.), from the Catskill Mts., co-types of salienta. Pears., 

 and of Nomenia 12 lijieata, Pack., as separated by me. He had advi.'^ed 

 me that he already had a good series of the western form of salienta; 

 hence lie would have before him both of our eastern and both of our 

 western sj^ecies for comparison with Walker's type oi comptaria. 



On Nov. 22nd I went to Cambridge, where, by the courtesy of Dr. 

 Henshaw, 1 was permitted to examine freely the Packard types. The 

 result was clarifying, if not altogether gratifying, for I found that in 

 uilieiita I had been guilty of adding another synonym to the many. It is 

 the perlineata of Packard without a shadow of doubt. The species I
