124 . THE CANADIAN ENTOMOLOIGST. 



established where it has obtained a foothold ; but it may be periodical in 

 its habits, and 1893 may have been with it also an exceptional year. 



In the Heterocera, I secured several good things which I had never 

 taken before. Acrojiycta grisea, a single specimen, and there was but 

 one example of it in the Society's collection. Xylomiges confusa, a single 

 specimen ; of this also there was but one in the collection, and that in 

 very poor condition. 



On the 31st of August, whilst strolling in a bit of woods to the east 

 of the city, I saw a conspicuously bright gray moth resting on the trunk 

 of a tree. Upon close inspection it proved to be new to me. When I 

 removed it from the spreading-board I compared it with what I thought 

 it most resembled, but the nearest approach that I could find to it was 

 Platycerura fiircilla. Shortly after I had occasion to examine the 

 D'Urban collection, and whilst doing so my attention was arrested by a 

 specimen labelled Aiidela acronyctoides, which recalled to mind my new 

 moth, and upon comparing them they were found to be identical, except 

 in freshness. Mr. Grote in his notes on the D'Urban collection (Can. 

 Ent., Vol. IX., p. 27), remarks : "The specimen is in poor condition, 

 but its ornamentation being marked, the species is quite recognizable." 

 That is a correct description of it as it is to-day, and my find is a fresh 

 and perfect duplicate of the type, and a really handsome insect. Prof. 

 Smith says in reply to my enquiry : •' Azidela acrofiyctoides is by no means 

 a common insect ; on the contrary, it is decidedly rare, and there are only 

 a few specimens known in collections. It has been taken in a number of 

 localities, always single specimens only, and generally very early in the 



season." 



Some of the late Geometers were quite abundant. From the 19th to 

 the end of August I secured about twenty Semiothisa caesaria, Hulst. I 

 found them resting on the trunks of tamarac trees, whilst later on 

 Petrophora truncata was quite plentiful. In the early part of October I 

 took over three dozen Epirrita dihitata, Bork. On the 9th I secured 

 tweniy-seven of them on the same trees from which I took the Caesaria. 

 The day was cool, and they sat close ; being very conspicuous objects, I 

 secured in about an hour's time all I saw of them, except one ; it was 

 sitting on the sunny side of a tree and arose as I approached it, when a 

 Phoebe bird gave chase and had it before it could reach another resting 

 place.
