The three last are new localities.
In England, at Hereford, in 1890, on R&s sa~ipc/nef.wi. (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. [Hcnahaw].
C/iionasfis furfurus has been cited as
being found at New Mexico (Bull. No. 3,
N. M,, Agr. Exp. Sta., Jan. 1891); hut Prof. Cockerell assi-ires me that it has never been found there. Walsh in Practical Entomolo- 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 lo the identification of the scales on these food plants.
Chionaspis furfurus Fitch is a native
species, and was first observed by Harris in 1841, 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 As$icSfoius flcrfr/r?>å´s A, cerasi\ Coccus karrisii, A.?//dtdius 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. Chiomsfis furfurus has
been received from Nova Scctia, New Bruns- wick, and Prince Edwards Island, and
many have been imported 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- gui under another name, but the determina- 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."
E~F. Hemispherical, rounded below, the
fiat base small ; strongly vertically ribbed, beaded, with ring-like rnicropyle. There are about. 40 ribs around the base, but they dirnini;h in number upward, not confluent and are finely beaded. Diameter -8, height .( 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, iv 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.
Stays II. Head pale greenish; width .6
mm. Body long, slender,feet of joints7 and 8 very small ; not shining sordid green with narrow white dorsal, subdorsal and broader stigmata! lines, none very distinct. Tuber- cles minute; setae distinct, dark, normal. Segments very indistinctly annulate.
Stage III. Head whitish green, not shin-

ing ; ocelli black, nmuth fainlly brown ; width I mm. Body green ; dorssil line
straight, white, crinkly edged; tubercles i and ii white; subdorsal line stmight, narrow, white; tubercles iii and iv less distinctly white ; substigniatal line distinct white, moderately broad, somewhat shaded below, just covering spiracles. Feet green, those of 7 and 8 smaller than the others. Tuhercle iv opposite lower edge of spiracle.
Siace /K. Head 1.8 mm. All pale green,
joint 12 a little enlarged; feet nearly equal. Lines and tubercles white, dorsal and sub- dorsal lines narrow, rather pulverulent ; stigmata1 moderate, enclosing- the spiracles except on joints 2 and 12, a dark green
shade above it reaching to tubercle iii. Feet green, shields and plate nncornified, obscure. Tubercles minutely black in white rings; iv at the lower edge of spiracle; setae rather long, fine, dusky. Spiracle while, finely black rimmed.
Staye V Head green, ocelli narrowly
black centrally, labrum white; width 2.7 mm. Green, plates invisibie; skin finely white dotted, lines white; dorsal line distinct, obsolete at the ends ; subdorsal narrow,faint, half as wide as the dorsal; stigmata1 narrow, about the width of the spiracles whichit half encloses except on joints z and 12, covering tubercle iv; a dark green shade above, diffuse, fainter at the spiracles. Snbventer white dotted ; feet clear green, equal, Body slender, joint 12 slightly enla~ged. Tubercles and spiracles white, the latter ringed.
Staqe V,? Head @le bro-\vu, shining-,
reticulate with darker brown, shaded in
clypetls and at bsise of antennae; labrurn whitisb; ocelli pale; ~vidth 4.6 111111. Body cylindrical, joint 12 a little enlarged on top; feet equal. Light yellow-brown ; dorsal and subdorsal lines narrow, pulverulent and
broken, brownish white, bordered with darker brown; obiiqn'e subdorsal shades brown,
running between tubercles i and ii forward and outward; skin mottled, dotted with
whitish; snhstigmatal line moderately broad, whitish on the edges, centrsilly of the color of the body, the lower edge finally fading out, leaving a very narrow pale line cutting the spiracles. Feet pale; setae white; cer- vical shield and anal plate not cornified, not lined. Spiracles white, black ringed. Later the larvae fade to a pale greenish brown, the lines becoming faint and the head appearing dark by contrast. Setae single, normal, iv opposite lower edge of spiracle,
The lasvae hatched early in May and
entered the earth in June. They fed on
various leaves, but seemed to prefer willow, on winch they throve. The imagoes ap-
peared in August.
