NOTES ON THE LARVA OF Ccitoccila habilis. \ja&\. summer while search- 

 ing for Agrotis under the loose bark of the hickory I was surprised to 

 find many larvae of the above named species. They are not gregarious, 

 as I afterwards learned, while feeding them in confinement, but are emi- 

 nently nocturnal and only feed by night and would naturally seek the shade 

 and protection of the loose bark during the day. Every strip of bark 

 sheltered more or less of them. They were made up of two broods. 

 The larger ones were nearly full grown, while the smaller ones had hardly 

 got through the second moult. The larvae of this species are so discom- 

 moded by light that they seek the darkest corners of the rearing cage during 

 the day, and at night if a strong light is brought to bear upon the bush 

 while they are feeding, they will immediately stop and will not go on with 

 the repast until it is rejnoved. I do not know whether the larvae of this 

 species has been written up or not. I believe little is known about a 

 majority of the larvae of this genus, but venture to say this one resembles 

 the larva of C. Ultronia in form, but is somewhat smaller and dark iron- 

 gray variegated with small white spots. The last pair of pro-legs are very 

 much spread or technically speaking, divaricate. When about to trans- 

 form to pupa they leave the bush and form a cocoon an inch or an inch 

 and a half below the surface of the ground. In this respect they differ 

 from others of the genus. The early brood came out winged flies the 

 i5th of July and the others a month later. R. BUNKER, Rochester, N. Y. 



ON Saturday, April 5th, Mr. Wm. J. Fox, of the Academy of Natural 

 Sciences of Philadelphia, and Mr. Charles W. Johnson, of the Wagner 

 Institute of Philadelphia, sailed for Jamaica. They go solely for the pur- 

 pose of studying and collecting the insect fauna of that island. They 

 expect to be gone from six weeks to two months. ED. 



THE LARV.E of Telea polyphemus generally are not found in any great 

 number on one and the same food-plants. Late in August, or early in 

 September, 1887, I took from three White Birches, none over fifteen feet 

 high and growing so close together that branches interjoined, fifty-six of 

 these larvae, about half of full grown size. A number of other adult larvae 

 of same were collected from Betula alba, near by, on the bank of Harlem 

 River, city of New York. RICHARD E. KUNZE, M.D., New York.
