PSYCHE.
[March 1890.
Cam/yZaca& oi'ivacea S&.- I have
specimens from Fort Smith and Fayette-
ville as well as from Mackey, I. T. The
earliest recorded date for its capture
is August second, the latest October
eighth, though doubtless some specimens
survive until settled cold weather which generally does not come until after
Christmas. It is a rather rare species
so far as my observation goes, though it is sometimes abundant locally. It oc-
curs in dry pastures.
Hespe~otetfix pratezsis Scudd. - A sin-
gle female was found in the summer of
1897 near Buffalo City, Marion County
which I refer to this species with some
hesitation. It was found in the mouth
of a gully at the foot of the divide be- tween Big Buffalo and White Rivers,
Timber occurred sparsely here but vege-
tation was abundant. A long search in
this vicinity failed to reveal any more
specimens.
Dend~otetfix @ercus Riley.-This spe-
cies is represented in my collections by one male and six females, all except one female captured near Clifty, Carroll
Co., June twenty-ninth. The female
referred to was taken near Elkins,
Madison Co., July thirty-first.
Parafyfotro$idia brunfte~i Scudd-This
very interesting and apparently very
rare species is found in Arkansas. It is represented in my collection by a sin-
gle pair, male and female, captured near Clifty, Carroll Co., June twenty-ninth,
I refer these specimens unwillingly to
the same species as they are remark-
ably different in the distinctness of the lateral carinae which are obsolete in the female and very distinct in the male,
and in the fastigium of the vertex, which is not perceptibly declivent in male and exceedingly prominent, while in the
female it is moderately declivent and
distinctly less prominent. In other re-
spects they agree as well as male and
female of the same species usually do.
The single pair, male and female, known
to Scudder were from Dakota and Texas
respectively. As the male was an im-
perfect specimen, the structure of the
furcula could not be given.
The Arkansas male shows. not the
faintest trace of furcula and the last
dorsal segment is not interrupted in the median line. The female at first glance
has very .much the appearance of a short winged Melanoplus bivittatus Say.
A NEW VARIETY OF CHIONASPIS FURFURUS FITCH, AND NOTES ON OTHER SPECIES.

I$ mm., while those of the convex forms are 3 mm. long and i wide, and these are covered more or less with the epidermis of the bark of the food plant, which gives the scale the appearance of being yellowish brown instead of white as in the typical C.fuyfurus. The female agrees very well with C. furfurus, found on several other food plants in this locality. The eggs arc dark purplish red. And the male scales are small and of the same normal form of the genus. The most
conspicuous difference is in the lively color of the epidermis white scale of the female, giving them a very peculiar and distinct ap- pearance from the scales of the typical C. furfurus.
Ilab. -Lawrence, Mass., Oct. 15, 1898, on buckthorn (Rhamnus catharticus L.) The
hedge infested is over 100 feet long, and to all appearances there is not a twig without some of the scales, and many of them
covered with them, so much so that they
are noticeable a long distance off.
Prof. Cockerel! suggests that I give a few notes on other species covered with epidcr- mis of their food plant, and has very kindly given me these references. Howardiu hicia- vis Comst. is a species normally covered by epidermis, but Mr. Maskell has given the name var. detecfa, to a form not so covered. As/idiotus cydomiae, var. tecta Mask. is a variety covered with the epidermis of its food plant as in C. fulvus. Cktouas$is
minor var. timida Ckll. (MS.) is also a
form covered by tiic epidermis of Ilibiscus, found by Mr. Barber on the island of An- tigua. Of course it is a matter of taste whether such forms as the above should he named. I believe, however, that they should be. Ckionns/is jurfun/s var. ul?ni Ckll. iti a variety found on elm at Brownsville,
Texas, by Prof. C. T. Townsend, and is
not covered with epidermis.
The food plants of Chionas'pis furfurus
Fitch are : choke-cherry (Pruws virgini- ana), black cherry (P. serati'fia), wild red cherry (P. $ennsyZuanicd}, wild and culti- vated apple (Pyrus sp.), crab apple, etc., pear (Pyrus cornmum's), peach (Persica vt~Igcris), Japan quince (Cydom'a ja-ponica}, cherry cur- rant var. (Rihes sp.), red flowering currant (Ribes saniyuineani), European mountain ash (Larhus ctnc-sfparia). The following in
Massachusetts : wild red cherry, pear, wild and cultivated apple, flowering quince
(PJWUS ju~o~iica), choke-berry (Pynts arbu- ttfolfa), shad bush (Amclcmchier canadcn- si.~), black alder (Clet7ira al?ifolia). The last four food plants are here recorded for the first time, and fonnd by mc; all of the others are from Dr. L. 0. Howard.

In England, at Hereford, in 1890, on Ribes sawgrc~ze~;~~;. {Morgan}. It is also found in Canada, being included in the check-lists of inserts of the Dominion of Canada, compiled by the Natural History Society of Toronto and published in 1883. [Hcnshaw],
Chionns$is furfiirus has been cited as
being found at New Mexico (Bull. No. 3,
N. M., Agr. Exp. Sta., Jan. 1891); but Prof. Cockerel1 assures me that it has never been found there. Walsli in Practical Enton~olo- gist, vol. I, p. 64, 1866, lists it as being very common on willow in Illinois. And Riley
in American Naturalist, 1881, vol. 15, p. 487, received them on raspberry from Oxford,
Miss. There is, perhaps, some doubt as to the identification of the scales on these food plants.
Chionas-bis furfurus Fitch is a native
species, and was first observed by Harris in 184.1, and was named by Fitch in 1856. It has been commonly known as the scurfy
bark louse and Harris bark louse, and cited by many authors as Aspidiotus /'~rft~rm, A, cerasi. Coccus ha~yisii, A.@i'diotus karrisii and Diaspis harrisii.
POSTSCRIPT. - Since the above was writ-
ten, I have received the following, kindly furnished me by Prof. James Fletcher of
Ottawa, Canada. Chionaspis furfurus has
bcen received from Nova Scotia, New Bruns. wick, and Prince Edwards Island, and
many have bcen inlported on nursery stock. It is not an uncommon species, but at the same time by no means of frequent occur- rence throughout Ontario west of this
point to the Niagara Peninsula and up to Lake Huron and Georgia Bay. It has not
been received from British Columbia.
DESCRIPTION OF THE LARVA OF CALOCAMPA CURVIMACULA. BY HARRISON G. DYAR, WASHINGTON D. C.
I received these eggs through Dr. Ottolen- p i under another name, but the deterrnina- tion was corrected by breeding. The mature larva has been briefly described by Dr. Thax- ter. The generic term Calocampa is utterly inapplicable to this species, as the larvae are plain, ordinary noctuids, far from '< beauti- ful."
Egg. Hemispherical, rounded below, the
flat base small; strongly vertically ribbed, beaded, with ring-like rnicropyle. There are about 40 ribs around the base, but they
diminish in number upward, not confluent and are finely beaded. Diameter .8, height .5 mm.
Stage I. Head rounded, pale brown, not
shining; width ,+ mm.
Body slender, gait
slightly looping, the abdominal feet of
joints 7 and 8 much smaller than the others. especially on joint 7. Joint 12 a little en- larged. Body smooth, light gray, food visi- ble; tubercles large, nearly black, circular, v equidistant between iii and v, vi not pres- ent ; setae dark, distinct, but short. Cervical shield brown; no anal plate. After feeding the larvae became pale green.
Stage II. Head pale greenish; width .6
mm. Body long, slender, feet of joints 7 and 8 veiy small ; not shining sordid green with narrow white dorsal, subdorsal and broader stigmata1 lines, none very distinct. Tuber- cles minute; setae distinct, dark, normal. Segments very indistinctly annulate.
Stage 111. Head whitish green, not shin-
