O. badia (which, after all, is a synonym of O. nova, Fitch) is the same 

 as O. antiqua, L. The synonomy will stand thus: 



Orgyia antiqua, L. 



O. nova, Fitch. 



O. badia, Hy. Edw, 



Hy. Edwards. 



Spilosoma latipennis. Stretch. 



This apparently rare species seems to have its home on Long Island. 

 I received it on one occasion from Rev. G. D. Hulst, and on the i6th 

 of June last I took a very fine pair near Flushing. It rs a most active 

 insect, and when disturbed flies rapidly to a great distance. In this 

 respect it is very unlike its congener, S. virginica. When about to 

 rest it settles on the under side of leaves, as is the habit of many Geo- 

 metridae. Hy, Edwards. 



COSSUS ROBINI/E CONGREGATING. 



Having obtained a few larvte of Cossus Robiniae from a locust tree 

 broken by a storm last winter, I kept them in a tin box with sawdust 

 and chips until the beginning of May. I then turned them into a 

 large glazed fern case outside my window; they had then partially 

 formed cocoons. About noon, June 22, I saw a female, with yet un- 

 developed wingSj crawl rapidly to the top of the vivarium, having just 

 emerged fr()m pupa. . In less than ten minutes several males were flying 

 swiftly round the house; about 50 large locust trees are exactly opposite, 

 consequently I could not be in a more favorable locality for this species, 

 but although I have carefully searched the trees during June and July 

 for several seasons, I never before found a male of this insect, and only 

 two females; yet, oxi this occasion I captured no less than 70 males in 

 fiine condition, all attracted by this one female during the afternoon 

 and evening. They flew in a rapid direct flight, making a loud buzz 

 (more like that produced by some Coleoptera than the hum of the 

 Sphingidae); the weather made no difference to their flight; the day 

 was bright, with occasional showers, but they flew just as freely in 

 the rain as in the sunshine. After dark, the number abated, yet an 

 occasional one flew in until ten o'clock, and strange to say, two fine 

 females of the sarhe species flew in my room to light the same evening. 

 Business called me from home next morning, so I killed the female for 

 a specimen. I had never seen any record of this insect being a day- 

 flyer, and think the fact will be new to many entomologists. The lively 

 habit of this species is in direct contrast with those of Cossus ligniperda 

 of Europe, which may be found in great numbers sticking on the trees 

 infested by them,a few inches above the empty pupa case, any afternoon 

 during their occurrence, both sexes being extremely sluggish duri.ig 

 the day. David Bruce, Brockport, N.Y. 



Samia Ceanothi. 



I received a few cocoons of Samia ceanothi from a correspondent in
