RARE CAPTURES. 



Dear Sir : In my letter with this heading in the March number, 

 p. 60, there is an omission of a word which quite alters my meaning. 

 Line 6 of my letter should read, " I- concluded that I had 7iot seen it 

 before." I took Pcedisca nisella, referred to at the same time, last August, 

 about twenty miles north of Hamilton, in the County of Halton. I found 

 it sitting on the trunks of small birch and poplar trees.

GRAPTA INTERROGATIONIS AT MONTREAL. 



Dear Sir : I was somewhat surprised to see the capture of the 

 above species at Montreal recorded as being an unusual and almost 

 unknown occurrence (Feb. number, page 40). In Mr. Caulfield's list, 

 Can. Ent., VII., 87, Interrogationis is given, " Rare ; May (hibernated); 

 July to October," and I have always considered it one of those species 

 which are neither rare nor abundant. The first specimen I have any 

 record of was taken by me in Mr. Trenholme's garden, Rosemount Ave., 

 Cote St. Antoine, on Sept. 7th, 1886. In the fall of 1887 it was abun- 

 dant at Mr. Trenholme's, and a number of specimens (all Fabricii) were 

 taken ; between that time and the present I know of about 40 other 

 specimens being captured in various parts of the town, and I succeeded 

 in rearing three separate lots of larva to imago during last fall, all feeding 

 on elm leaves. The form '■'■ umbrosa " seems to be much rarer here than 

 Fabricii, but a few have been taken by Mr. P. M. Dawson and other 

 collectors. I saw a single specimen oi Interrogationis at St. Rose, P. Q., 

 July 6th, 1889, but was unable to catch it.

Errata. — The following corrections should be made in Dr. Hamil- 

 ton's paper on "Balaninus" in the January number :— Page i, line 23, 

 and elsewhere, for "■proboscoidetcs" read ''proboscideus" Page 5, line 33, 

 for " nostrum " read " rostrum," Page 6, line 34, for " three first'' read 



*' first three."
