296 THE CANADIAN ENTOMOLOGIST. 



the inside. At night it is illuminated both inside and out with electric 

 arc lights. The walls, I should judge, are about thirty feet in height. 

 Situated as these buildings are, near the cemetery, some parts of which lie 

 untouched by the hand of man, being in a truly primeval condition, you 

 can see at once that the place is exceedingly favorable to the entomolo- 

 gist. It seems that these white walls, together with the electric lights, 

 form a moth trap which no entomologist could improve. The ends of the 

 building are, of course, left open. This place is a veritable fairyland for 

 the entomologist. During a storm insects of all kinds will fly in, and are 

 easily captured. Among the Lepidoptera which I have taken are the 

 following : Attacus Iwia, A. Cecropia, A. Polyphemus., A. Frot?iethea, 

 Eacles hnperialis, Saturnia lo, Arctia acrea; over twenty different 

 species of Hawk moths, and many others too numerous to mention. As 

 I am only collecting Lepidoptera, I have not paid much attention to the 

 other orders of insects. The Coleoptera are also very abundant. 



Before I close, I may speak of Argynnis aphrodite, which I never 

 saw so common before. On going into a meadow a dozen will fly up at 

 your approach, while they are over everything and everywhere. Never 

 here have I seen a butterfly in such numbers.

ATTACUS PROMETHEA. 



Sir, — Having noticed Mr. Moffat's communication regarding Attacus 

 promethea in the August number, it occurs to me that the following may 

 prove of interest. On June loth, while in Milton, Mass., I placed two 

 females in a box on the piazza for assembling. About 3 o'clock in the 

 afternoon a male was observed flying around the house. He was cap- 

 tured, and a short time later another appeared. They kept coming at 

 intervals until about half-past five, and after that none were seen. There 

 were ten in all, of which number eight were perfect. On the next day, at 

 about the same time, they began to come again, but very much more numer- 

 ously. At the end of the afternoon, twenty-nine had been taken, besides 

 a large number which were not collected, because of imperfections. The 

 moths were not seen either night. The next day no more moths put in 

 their appearance, and the females were removed. Besides this occasion, 

 I have several times seen the male moths flying around, when there were 

 no females in the vicinity. I have never seen the females fly by day, 

 however, or the males except between three and six o'clock. It seems 

 to me that Promethea is habitually a day flyer, but I have never seen 

 any other of the Saturniidae on the wing during the daytime. All the 

 males which assembled showed the same apparent blindness which Mr. 

 Moffat speaks of James A. Field, Milton, Mass.
