the substances on which they feed, and have other habits, in the 
main very unlike those of this apple tree worm. The winged 
moths which this apple tree worm produces, belong to the genus 
named Chcetochilus, by Stephens and Westwood, Rhinosia , by 
Treitschke, Ypsolop/ius, by Curtis, and Aneychia , (probably), by 
Hubrrer. Which of these several names was first published, and 
therefore has the right to be retained for our insect, I have not at 
hand the means for ascertaining; the name of Treitschke, how¬ 
ever, must be rejected, Mr. Kirby having long since given the 
name R/iinosia, to a genus of weevils. The insects of this genus 
are chiefly distinguished by having their feelers clothed at base 
with very long scales, which project horizontally forward from 
the head, resembling a beak, and from the middle of the upper 
side of these scales, the last joint of the feelers is protruded up¬ 
wards like a spur. 
I had prepared a description of this moth, to be appended to 
the account which I had already given, but have to-day received 
from Dr. Harris a slip of a newspaper communication, dated the 
19th inst., in which he names and describes it, from specimens 
w'hich he has recently reared from some of the worms sent t.o 
him. He names it Rhinosia pomdella (from the Latin pometum , 
a synonym of pometariun i) or “The little Rhinosia ot the or¬ 
chard.” But, for the reason above stated, I think we must adopt 
Mr. Stephens’s generic name, and call our insect Chatochilus po- 
mefellus. Dr. Harris describes the species, as follows: “ Fore¬ 
wings ash-gray, sprinkled with blackish dots, three of which, 
larger than the rest, are placed triangularly near the middle , a 
dusky, transverse band near the tips, and a curved row of seven 
black dots at the origin of the terminal fringe. Hind-wings, dus¬ 
ky, with a leaden lustre, black veins, and very long black fringes. 
Body and legs beneath, yellowish-white, with the lustre of satin. 
Expansion of the tvings, five-eighths of an inch.” 
This description applies with sufficient exactness to the insect, 
which, however, is subject to great variety. I have a host of 
specimens before me, reared from the worms, and captured upon 
the wipg every where in our orchards and forests, since the first 
week ot the present month. On the 8th inst., a large white oak
