MISCELLANEOUS NOTES. 



Personal.— -We beg to acknowledge with many thanks the receipt of 

 some eggs of Saturnia Eglanierina Boisd., from Prof. J as. Behrens,of San 



Francisco, Cal. The eggs arrived in perfect safety, and will, we trust. 

 produce some good specimens. We shall be glad to receive from Prof. 

 Behrens any Entomological material for our pages. Ed. C. E. 



In No. 4 of the Canadian Entomologist, Mr. Couper makes some 

 remarks in reference to the larvae infesting acorns. Having just succeeded 

 in breeding the imago I can throw some light on the subject. On October 

 11, rSyo, I happened to observe that the acorns of a red oak ( Qjtcrcus 

 rubra) contained larvae of some sort, and, making an examination. I found 

 many ot them containing from one to four short stout footless grubs, that 

 I supposed were the larvae of some species of curculionidce.. ( Hhers in 

 which a hole had been made and carefully closed again, contained Lepi- 

 dopterous larvae, varying greatly in size in different specimens. Whether 

 there were parasites, or merely took possession of the acorns after they 

 were abandoned by the curculio larva?. I was unable to decide. Taking 

 home a couple of quarts of the acorns, I put about half of them in a 

 glass-covered box with a couple of inches of earth at the bottom, and the 

 remainder in a dry box with glass sides. In both cases the larvae began 

 directly to leave the acorns, those in the box containing earth immediatelv 

 burrowing out of sight, while those in the other box continued to crawl 

 from side to side until cold weather came on, by which time all the acorns 

 were abandoned except those containing" lepidopterous larvae. Soon 

 after cold weather set in, the unprotected curculio larvae shrivelled up and 

 died. By digging at different times in the earth in the other box, 1 ascer- 

 tained not only that the grubs were alive, but that they remained in the 

 larval state during the winter, spring, and first part of summer. In the 

 latter part of July, 1871, the first pupa was obtained, and on August 20th 

 I turned up an imago and also a larva. On the 23rd day of August the 

 first mature imago made its appearance, since when they have continued 

 to come out at the rate of one a day. The species is without doubt the 

 Baianinus nasicus Say, of the Canadian list of Cpleoptera ; but Dr. Horn 

 informs me that it cannot be referred to any of our named species. I 

 have live specimens dark in color and somewhat mottled. I put a branch 

 with a few acorns on it into the cage with them, and saw a couple shortly
