they are of tlie same blood-red hue as those on the first segment. The small dorsal tubercles on 
the second and third abdominal segments are minute and yelloM'; those on the fourth are partly 
blood-red. The anal legs are long and slender. On the back of the abdominal segments 1-4 is a 
porcelain white band, bordtaed with faint yellow, and divided by the sutures j the portion on the 
iirst segment behind the tubercle is triangular, that on the fourth round; they each contain three 
deep pink lines more or less broken and irregular. The V-shaped mark consists of a white oval 
(acute in front) spot on the sixth segment, and the two arms of the V are formed by two coin'erging 
oval spots, with a yellowish white spot between the forks. The thoracic legs are pale llesh, the 
middle abdominal legs of the color of the leaf-stalk, while the anal legs are paler. Beneath, the 
body is green on the three thoracic segments, this color being continued back as a narrow band 
to the first pair of abdominal legs; otherwise much as on the sides of the body. 
Larva compared wiih that of 8, niiirornis, — Ditfers from C. unieornin in the head being purple 
and having four dark narrow lines extending from the base of the jaws to the vertex; the dorsal 
spine on the first abdominal segment is nearly three times as large and high as in (7. iinicorHis, 
and ends in a deep fork, each tine of which bears a stiff truncated spine. A pair of dorsal, 
rounded, vsmall tubercles on each abdominal segment 1-S, those on the fifth and eighth segments 
being much larger than the others and coral red in color. Coloration much as in C.V7iicor)}iii,hiit 
the branches of the V in front of the tubercle on the eighth segment are wider and inclose a 
broken red line. Meso- and metathoracic segments green; body brick-reddish, slashed with pale 
lines, with a broad dorsal band forked on the prothoracic segment and extending upon the horn 
on the first abdominal segment; behind the horn are four dorsal, oval, light patches, each inclosing 
three red lines. 
Cocoon , — Earthen, regularly oval in shape, externally covered with sand, so that it closely 
resembles that of Xylmodes Ugnkolor. (Eiley.) 
“The single specimen of the cocoon of this species in the national collection was constructed 
in a sandy soil, and is extremely thickly covered with particles of sand, entirely concealing the 
silken inner structure, which seems to be somewhat more copious and dense than in the case of 
8, luvicornis. The cocoon is elongate oval, measuring about 22 mm. in greatest diameter.” (Kiley 
MS. notes.) 
Pupa . — Moderately stout; end of abdomen obtuse. The cremaster deeply cleft, each spine 
well develoi)ed, rather long, not much flattened, ending in a point, and throwing off near the end 
a short branch which nearly meets its fellow on the (►pposite S]une. Length, 21 mm. 
Two (5 . Body not very stout (head not preserved in any cast shells), smooth, shining. 
Hinder edge of the thorax with eight square, dark tubercles, with rudiments of a ninth. 
Abdominal segments 5 to 7 shagreened on the hinder edge, and segments G to 8 punctured 
(these punctures acting as ball bearings!). Cremaster ending in two stout spines forked at 
the end, much larger than in 8, nnicornis, and transversely corrugated. Length, 18-19 mm.

jjabits . — The following notes and descriptions are based on an exaniinatiou of the material in 
Professor Eiley’s collection. The larva occurred on the oak September 24. In Virginia one was 
found by Mr. Koebele on the birch September 14, and it has also been bred from the blackberry. 
The larva makes an earthen cocoon, regularly oval in shape, covering it with sand on the outside, 
so that it closely resembles that of A^ylinodes lignieolor, €, unicornis spins a silken cocoon, with 
debris collected and adhering to the exterior. It is evident that C, cinereofronfi Pack, is only a 
variety of bu/ntfata,, there being a series of connecting forms in Eiley’s collection now in the 
United States National IMuseuiu. The moth occurred at Cambridge, IMass., June IG, and in July 
and August. (Harris.) 
“Larvm of this species are fimnd from May to October at St. Louis, Mo., feeding on the 
different kinds of oak and on maple. The moths issued in Ai)ril and August. The coloration of 
the larvm is quite variable, though the most uniform marking is as follows: Color, green, speckled 
with purple. A faint substigmatal sulphur -yellow line, most distinct on thoracic joints. A broad 
pale subdorsal line, between Avhich the dorsum is pale lilaceous, but thickly mottled with rich 
purple-brown and ferruginous, leaving a narrow dorsal line distinctly marked. Two elevated
