40 THE CANADIAN ENTOMOLOGIST. 



Dear Sir : I was particularly interested by Dr. Horn's remarks on 

 labyrinthica or pnirsa in his notes on Chrysomela in a recent number of 

 the Can. Ent. When on the 23rd of May, 1881, I captured my first 

 specimen on the wing, I regarded it with great satisfaction. The pure 

 white of a fresh specimen contrasted with the glossy greenish black of its 

 peculiar markings, makes it an exceedingly attractive object to the eye 

 when first seen. I secured thirteen that season. Being eager to obtain 

 its name, I sent specimens where I thought it likely to be got ; they in 

 turn applied to others, and then informed me, to my no small disappoint- 

 ment, that it was nm/tiguttis. We find it restricted here exclusively to 

 one locality, and that not extensive. In 1882 I searched carefully for it, 

 and secured nineteen. On one occasion I found one paired with a 

 scalaris, but scalar is is rarely met with there. In 1883 I took over eighty 

 piirsa without any special effort, and did not see half a dozen scalaris 

 that season in that locality. My first capture of pnirsa in 1883 is dated 

 12th June; on the i6th I took nineteen, on the 21st, twenty-one. The 

 last noted is the 9th July, but they were seen after that. Being from home 

 during their season in 1884, I saw nothing of them, but was informed they 

 were quite scarce. I have inferred that it cannot be a very abundant form 

 from the fact that when it was sent to collectors in Buffalo and New York 

 who have extensive collections and much experience in exchange, it was 

 unknown to them. I find it very liable to discolor when drying, the white 

 becoming rusty, which detracts much from the beauty of its appearance.

Dear Sir : In reply to the question of Dr. Hagen (Can. Ent., v. 16, 

 p. 239-240) concerning the distribution of Xyloryctes satyrus, it may be 

 of interest to note that the species has been recorded from various parts 

 of Canada by Bell, D'Urban, Hamilton, Harrington, Pettit, Reed, Ritchie 

 and Saunders ; from Mass. by Harris (specimens from Martha's Vineyard 

 and New York are in his collection) ; from Long Island, N. Y., and 

 Illinois, by Walsh ; near Buffalo, N. Y. (Lesch & Reinecke) ; near Cin- 

 cinnati, Ohio (Dury) ; Lower Michigan (Hubbard & Schwarz) ; Daven- 

 port, Iowa (Putnam) ; Kentucky (Siewers) ; Texas, Kansas, Neb., Ariz. 

 (LeConte) ; N. Mex. (Hamilton) ; Eastern, Middle and Western States 

 (Ulke). I have collected it in Western Massachusetts and Rhode Island, 

 and have specimens from Pa., Md., Wise, and Mich.
