September 1897.1 PSYCHE. 119
some excuse for Osborn's redescription
as the original description of micolor-
atus (not Gc unicolorous ") is not exact as regards female segment. A bent
condition of the abdomen gave a very
improper view for this part. Relaxing
and remounting show it to be identical
with oculaf-us.
Deltocefhalus uvgenteolus Uhl. I
have typical specimens of this species
from Dr. Ubler, and also abundant
material collected by myself on the plans in northern Colorado. I have also the
types of curtifennis and tercbrans and
further specimens of both collected in
1896. Such an error as the reference
of these two species to argcnteolus
seems inexcusable. Arfre.nte0l.u~ is
small, slender, the female segment
nearly truncate, the head immaculate,
and the general color when fresh a bril- liant, resplendent green. Curti-pennis
and terehrans are much larger, the
head more obtuse, and heavily maculate,
the female segment deeply emarginate,
and the general color dull brownish
cinereous. Termbans was referred to
Eutettix on account of the rather
unusually strong transverse depression
before the tip of vertex. It is an
Athysanus and may prove the fully
winged form of curti-pennis, but. there
is less than no proof for it now, and
hence for the present they must be kept
separate.
THE LARVA OF CROCOTA OPELLA
GROTE.
Bey. Slightly more than hemispherical,
not narrow at base, flat below; shining
pearly, faintly yellowish; diameter .55 mm. Reticulations obscure, narrowly linear, like fine lines traced on the otherwise smooth and level surface, mure or less elongate, irregularly hexagonal.
Stage I. Head bilobed; pale reddish
brown; width .3 mm. Body whitish with
very long black hairs, single, normal, i-i- present. Hair spinulated, i-iv black and especially long. Tubercles large, the edges adapted in slope to each other, luteous gray. Stage II. Head whitish, eye black, mouth brown; width .38 mm. Body whitish, the
warts concolorow ; i very small, one-haired; ii large, many haired. Feet all pale. Hairs slender, black, many of fair length and a few much larger, distributed all along the body. Last stage. Head black above, clypeus
and sutures brown; width 1.8 mm. Body
uniform dull gray; warts and plates black. Hair stiff, black, short and uniform except from wart ii on thorax and iii on abdomen where it is long, forming a curious ridge of hair the whole length in the middle of each side. No marks.
Cocoou a slight sticky web of white silk. The pupa recalls H~~pka~tria in appearance. The eggs are laid at the end of July and the larvae hibernate about half grown. The egg patches are placed on the leaves of bushes and trees, but the larvae drop to the ground on hatching. They eat almost any tender
leaves, as with other Arctians. Found at Greenwood Lake, N. J., and Bellport, Long Island, N. Y. Harrison G. Dyar.
