TRANSPARENT wings, colored or uncolored, detached from the body 

 of an insect can be placed between two lantern slide covers and used as 

 lantern slides, a few minute drops of glue serving to hold the wings in 

 place. Any necessary lettering can be put on bits of Dennison's adhesive 

 transparent tape, or of sheet gelatine, and inserted between the two glass 

 covers before binding them together in the usual way. P. P. CALVERT. 



EREBUS ODORA IN WISCONSIN. The small village of Oostburg can be 

 found on the map forty-two miles north of Milwaukee and ten miles 

 south of Sheboygan in Sheboygan County, Wisconsin. On July 27, 1898, 

 I went out on my usual night trip to catch moths near the woods, where 

 I sugared some tree-stems. Hundreds of insects appeared, of different 

 sizes, and one was a very large one. Waiting for a favorable opportu- 

 nity to strike with my net, I was rewarded with an almost perfect female 

 Erebus odora. 



On the night of July 22, 1907, I imagined that two bats were flying near 

 my sugared trees for the purpose of devouring the moths which covered 

 the tree-stems. Directing the red light of the bicycle-lamp toward the 

 tree-stems, I saw a male and female Erebus odora feasting on the sweet 

 I had provided. I caught the female that same night and July 24th I 

 captured the male. Both specimens are almost perfect. On the night 

 of July 27 and 29, 1907, I caught two female Erebus odora. One was 

 somewhat damaged and the other very much injured. The last speci- 

 men I put in a large box, covered with screen, under the trees, expecting 

 soon to catch the male As it did not appear within a week I took the 

 female out and found it had deposited two hundred or more eggs, scat- 

 tered all over the inside of box and screen. The eggs are of the size of 

 cabbage-seeds, green of color, and round. About fourteen days after 

 they were deposited the larvae emerged, i did not know the food-plant 

 of this caterpillar and, to my sorrow, all died of inanition. 



It is an open question to me if the Erebus odora does breed in this 

 vicinity. Of the five specimens I captured three are almost perfect and 

 one fairly good. If they are stragglers from the South, could it be pos- 

 sible for them to arrive here in such a good condition ? In making the 

 long journey from the South they were certainly liable to be killed by 

 bats or night-hawks or other enemies before they ever reached this 

 northern country. Dr. J. VV. Holland writes me that the larvae feed on 

 cassia in Cuba. 



Do not some of the readers of the NEWS know of another food-plant 

 to which the larvae of the Erebus odora take? 



On September 2, 1907, I caught a female Erinnyis ello on the flowers 

 of the petunia. This insect likely was a straggler from the South, and 

 still it is a perfect specimen. 



I will be glad to hear from readers of the NEWS any opinions and ex- 

 periences with regard to Erebus odora, and I would like to know if those 

 insects breed also in our northern climate. ED. WAS, M.D., Oostburg,
