through all the stages being but thirty- five days. Whether one or more
broods nrc raised before the one that
lives through the winter. I am unable
to SAY, though it may reasonably be
presumed th~t such is the case. The
last brootl remains in the larwl .stage
througho~il the winter, usually ctnci ging its adults in the kitter half of April.
The parasites affecting this insect sire all of small size, and one cell in four on an average is affected. Those bred by
the writer are as follows :
Chå´ry.r/ farvzda Fabr. Two spec-
imens.
Encyr/its sp? These tiny parasites
had attacked the larva of the bee, con-
suii~ing the whole interior and leaving
the skin intact. Within this covering
the pupae of the parasite, from 10 to I j in number, were closely packed. The
adults issued in the last week of Feb-
ruary and the first week in May.
Aetroxy~ aaafis Ashmend 11. sp.
I I specimens.
9. Length 5.1; mm. Bror1z.v green, scaly pnnctste, the tip of the abdomen yellowish ; scape and legs, except come, ferruginous, tlie knees, tips of tibiae and tarsi more jel- lowish. Wings hyaline, the veins pale
brown, the marginal vein about one and one- half times as long as the stigmiil, the post marginal vein as lung as or slightly longer than the marginal. Abdomen very long
acuininate, 1'1illy twice as long as the heid and thorax united.
3.' Length 2 to 2.5 mm.
Differs only in
the shape of the abdomen which is elongate and only one-third longer tlian tlie he;id and thorax united, while the flagellum is filiform, pubescent, the first joint :lie longest,joinis 3 to 5 subeqnal, about twice as long ;is thick. Mr. Ashmciid, in a note appended to
this description, s:iys : " The untenriae in the $ are broken oft' at the pedicel, and I am therefore unable to tell to
what subgenus of Aetroxys it belongs.
The very long- abdomen, wliich is
tipped with yellow, rcailily distinguishes the species."
These eleven specimens were bred
from six cells, five occupying one, and
two each nS the other three cells. On
pupating they adhered togetlm hy the
tip of the abdomen in one ~n'iiss. All
issued May 29.
THE NUMBER OF STAGES IN APATELODES TORREFACTA. BY HARRISON G. DYAR, NEW YORK CITY
I have already referred to the varying
number of stages in this species (Psyche, vi, 146) as found by different authors;
Miss Soule finding five and Dr. Pack-
ard six, while I presented evidence indi- cating eight stages. I returned to the
subject last summer, as I succeeded in
obtaining eggs by the assistance of
Mr. Jacob Doll from whom I purc1i:ised
living pupae and.Miss Emily L. Mor-
ton who very kindly attended to the
matin: of the moths bred from them.
The larvae exhibited five stages, but a
consideration of the width of the head
makes the whole matter clear. I gave
the following series as probable, in my

previous note: .64, .8, 1.0, 1.3,
1.6,
2.1 2.6, 3.2 mm.
The present larvae
exhibited .65, .8, 1.3, 2.2, 3.3, thus
omitting every alternate stage after the second. In my larva formerly described,
the last four ~ncasiireine~~ts of the nor- mal series were actually obseiveci, and
the larva must have had as many as
seven stages, omitting normal iii, or
perhaps eight, includingiii. It is prob- able that in Dr. Packard's example but
two stages were omitted, although we
cannot say which, as he does not give
us measurements of the head. Miss
Soule's was doubtless the same as my
hist.
I will not describe the egg and larval
stages in detail, as there is hut little to add to tho ac,counts already publislied. The arrangement of the liaiis may be
mentioned, as it is decidedly peculiar.
There is no primitive lirst stage.
On
latching, the hairs are abundant, arising fiom low, flat granular wan areas.
whose position is most difficult to dcter- mine positively, as they are obscured by the hairs, and when the latter arc
rcnmvcd are difficult to clisting~iish,
being merely concolorovs granular
On June 11 I found two larvae on fi grape- vine, and a few days later five more on
Am-pelofsis qztinquefolid. The record is taken from the first two.
Length å´fl inch.
Head round, green, with
4 very faint yellow face-lines.
Body bright
green, transversely striated willi opaque yellow. 3rd und 4th segments very slightly enlarged, too slightly to be noticed except areas. After repeated observation, I
believe the accompanying cut represents
their arrangement correctly. The hairs
are represented as partly removed. On
the abdomen i, ii, iii normal, iv very
large and v small, vi large, the base of the leg hairy. On the last two thoracic
segments three warts above the stigma-
tal wart. the middle one moved back
out of line with the others, stigmata1
and subventral warts normal. I could
not determine the exacf. period at which the secondary hairs uppcarecl ; probably ill stage ii, though in my notes I state tk secondary hairs not seen, if present
can not distinguish them from those
bending over from the war1.s." In the
last stage, the secondary coating is well developed.
by an enLomologist.
From the outei face-
lines to the caudal horn extended bubdorbul lines of yellow, edged above with dark
green. A stigniatal yellow edge ran from the first segment into the first oblique on each side. There were eight yellow obliques the eighth being under the caudal horn, and running backward from that. Anal shield
edged with yellow. Caudal horn lung,
slender, straight, black, rough. Feet yellow, props green, venter plain green.
