I recently sent Prof. Fern aid a number of both forms of the 
moth, which had been bred from apple during the last two 
years in the hope of determining whether Packards oxycoccana 
(of which Prof. Fernald possesses the type) is a synonym ot 
minuta. But Prof. F. replies (Dec. 27, 1886) that the Cinderella , 
specimens “do not approach the type of oxycoccana any nearer 
than many others which I have seen, so I am still m doubt about 
oxycoccana .” 
DESCRIPTION. 
Eaq .—I have not seen the egg. Dr. Biley in the Index to the 
Missouri Beports says: “The eggs of this species are very flat, 
circular, and translucent, with a diameter of 0.7 mm and are laid 
singly on the under side of the leaf near the midrib. To this 
Ml Smith adds that the egg is “precisely like that of Anchylopera 
vacciniana in form and color, but is very slightly larger. (U. b. 
Dept. Agr., Div. of Ent., Bull. No. 4, p. 24.) 
Larva .—Length 12 mm. Body thickest just in front of the 
middle, tapering very slightly both ways. Color pale ko^ey- 
yellow with a slight greenish tinge. Head and prothoracic shield 
gamboge-yellow; former nearly as wide as latter. Mouth parts 
darker. Ocelli on a nearly crescent-shaped black spot on either side 
of head. Another dark spot at base of head laterally, and 
sometimes a slight trace of a brown line connecting the two, so 
that the whole resembles somewhat the letter S. Body sparsely 
furnished with fine pale hairs arising from prominent polished 
tubercles, the hairs varying in length, the longest being about 
half as long as the body is wide. The four dorsal tubercles aie 
arranged in a trapezoid, with a deep crease between tne anterior 
and posterior pairs, the tubercles of the posterior pair being 
farthest apart. Stigmata pale, on middle segments situated slight y 
posterior to a line connecting the two lateral tubercles and nearest 
the upper tubercle. Thoracic feet usually tipped with black. Just 
below tip of dorsal portion of the anal segment and above the 
anal opening is a nearly vertical plate bearing a series of rows ot 
peculiar blunt bristles, curving slightly upward, those above being 
shorter than the lower ones, so that the whole forms a stiff brush. 
(Possibly it is by means of this that the larva is enabled to send 
off its excrement to some distance when it defecates,” as noted by 
Mr. Trouvelot in Dr. Packard’s article cited above.) 
Described from many specimens feeding on apple. 
Biley’s description of the pupa is as follows: 
p uva .—“Length 0.25-0.30 inch. Brown; characterized by a pe¬ 
culiar rounded projection from front of head; by a little pointed 
Drominence at base of each antenna and each side of penultimate 
abdominal joint; and by terminating in a broad suppressed piece 
which produces two decurved hooks. Posterior rim of abdominal 
joints rasped dorsally, and a slight rasped dorsal ridge near the
