108 The Ottawa Naturalist. [Sept. 



EuxoA Personata Morr. is, on the whole, a somewhat 

 smaller species. The largest example in my series of 10 males 

 and 6 females is 32 mm., in expanse, while the average does not 

 exceed 29-30 mm. The ground color usually contains a distinct 

 tinge of reddish and the surface is coarsely powdered, yet lacks 

 that blotchy appearance seen in the darker examples of detersa. 

 Taken as a whole, the series does not suggest quadri-dentaia, but 

 does contain an approach to the messoria type. There is no pale 

 streak in the sub-median interspace beyond the claviform, 

 although there may be a slightly paler area to the t.p. line. The 

 median vein is not white or pale marked, veins 4 and 5 are not 

 rayed, although the s.t. line may be slightly indented at those 

 points. The ordinary spots are less contrasting than in detersa 

 and the reniform is distinctly broader, more regularly kidney- 

 shaped, the outer margin never bent inward to form a constric- 

 tion. Perhaps the most characteristic feature of this form is the 

 completeness and distinctness of the median lines, the t.p. being 

 usually crenulate and broadly outcurved, while in almost all 

 examples there is a traceable median shade line, which becomes 

 obvious in many specimens. 



In the series before me the detersa come from St. John, New 

 Brunswick, VIII, 18-30; Ottawa, Ontario, VIII 24, IX 8; 

 Webster, New Hampshire IX 8; Cohasset, Mass., IX 3, X 15; 

 Albany, New York, IX; Anglesea and Bayside, New Jersey, 

 late August and throughout September. Personata is from 

 Canada, Vll 27, IX 14; Denver, Colorado, VI 10; Rounthwaite, 

 Manitoba, no date; Aweme, Manitoba, VII 13, VIII 25. 



It is certain, of course, that the distribution of both species 

 is wider; but material of the latter is short because the species 

 is a common one. Personata was described from Galena, Ills. 



NOTES. 



Still Another Case of Natural Grafting. Mr. H. 

 Groh's note in the June number of The Ottawa Naturalist 

 recaUs to my mind that at a field meeting of the Natural History 

 Society, at Chatham Island near Victoria, on the 7th May last, 

 an instance of a natural graft of an oak tree was found at the 

 spot where the excursionists landed. The tree is but a small 

 one and at a point about four feet from the ground a branch has 

 apparently been bent over and become incorporated with the 

 trunk, leaving an oval opening about 18 inches in diameter. 

 One of the ladies of the party, realizing its suitability as a frame,
