590 FIFTH EEPOET OF THE ENTOMOLOGICAL COMMISSION. 
Ing from the occiput to the labruin ; also ■ lateral, rather paler, band extending to 
the black eye& Body speckled irregularly, especially on the sides, with brown. A 
dark donal vascular line, inclosed by two slender tiue yellowish lines. Length, 17 mm . 
74. LiARGB HBMATUfl P LARVA. 
This false caterpillar occurred frequently ou the willow at Bruns- 
wick, Me., late iu August. 
Larva.— Eight pairs of abdominal legs. Body rather thick, long, not usually curled 
up much at the extremity, with no markings, warts, or spines. Head small, round, 
amber, greenish in front, eyes distinct and black. Body wrinkled, much as in Cim- 
bex, which it approaches in size, pale green throughout ; with a dorsal pair of lines 
composed of obscure diffuse irregular faint yellowish patches on each side of the 
vascular line ; and a similar lateral line, also obscure. Length, 20 mm . 
75. Chry8omela bigsbyana Kirby. 
Mr. Coquillett has reared this leaf-beetle from the willow, ou which it 
feeds. He fouud in Illinois two larvae August 13, which shortly after- 
wards pupated, the beetles appearing September 5. The species was 
determined by Dr. Horn. (Can. Ent., xv, p. 22.) It is not uncommon on 
willows in Maine late in June. 
Larva.— Body white, tinged with yellow ; spiracles black with a white dot in the 
center of each ; on each side of segments 2 and 3 is a curved black dash, the curve 
downwards; cervical shield concolorous, marked with a blackish spot in the middle 
of each outer edge ; head yellowish browu, ocelli black, in two clusters. Length, 
10 mm . 
The beet le. — Body green, palpi, antenna?, and legs rufous ; anterior margin and sides of 
the prothorax reddish ; elytra pale red withasutural stripe, a humeral broken bilobed 
spot, and several dots black or dark green. Color and sculpture of the body like 
those of the preceding species, from which C. bigsbyana differs principally in having 
the sides and anterior margin of the prothorax reddisu yellow ; the eh tra are of the 
same color, but the suture itself, especially at the base, a stripe parallel to it, a large 
humeral bilobed spot, the interior lobe of which is obtusangular or broken, and 
several irregular dots and spots on the elytra are black-green. Length of the body 
4 lines. (Kirby.) 
76. Chrysomela spirece Say. 
I have found this species on willows in Maine late in June. 
The beetle. — Head dark green, tinged with brassy ; antennsB and palpi rufous ; 
thorax dark green, tinged with brassy ; elytra pale yellow, sometimes tinged with 
rufous; each with about seventeen unequal small green spots; a larger lunate one 
originating on the humerus ; a common green sutural line, which sends off a lateral 
short branch on each side near the base ; beneath blackish green ; feet rufous. 
Length, 4; inch. 
It is very closely allied to the C. philadelphica Fabr., but is smaller, and the sutural 
Hue is always common, whereas in the philadelphica there is a slender subsutural line 
ou each elytron always insulated from the suture throughout its whole length. 
77. Chrysomela philadelphica Linn. 
While this species feeds on the pine, according to Fitch, he also has 
observed it commonly on the willow. 
The beetle. — A very convex broad-oval beetle about 0.30 long, of a dark bottle- 
green color, with white wing-covers sometimes tinged with yellow and having on
