forms a right angle. Upon each side of the head behind the eye is also a minute tooth 
of the same size with those along the sides of the thorax. The surface is slightly 
clothed with minute inclined bristles. (Fitch. ) 
5. THE NOTCHED-WINGED GEOMETER MOTH. 
Eugonia alniaria Hiibner. 
Order LEPIDOPTERA; family PHALNID#. 
Feeding on the chestnut, a bluish-green caterpillar, with wrinkles, and on the 
eleventh segment two little warts tipped with brown; transforming to a light ochre- 
yellow moth with wings deeply notched. 
This caterpillar was found by Mr. L. W. Goodell on the chestnut at 
Amherst, Mass., August 20; on the 21st it drew a few leaves together, 
and spun a thin, silky, pear-shaped cocoon; became a chrysalis the 24th, 
and was transformed to a moth September 15. 
Larva.—Body two and three-tenths inches long, the body largest near the tail, and 
tapering to the head; bluish green, with a thick wrinkle on each ring, those on the 
fifth and eighth thickest and light-brown; on the back of the eleventh ring two little 
warts tipped with brown. (L. W. Goodell. ) 
Pupa.—One and two-tenths inches in length, bluish-white, ending in a flattened 
tail, tipped with black, and on each edge three small black spines, each ending with 
a minute hook. (Goodell.) 
Moth.—Short bodied, quite hairy; male antennie heavily pectinated, wings deeply 
scalloped; delicate ochre-yellow, with a reddish tinge towards the edge of the wings, 
and on the head and front of the thorax. Fore wings with two lines, often inter- 
rupted, or only developed on the costa; inner line on the inner third of the wing; the 
curved outer line, beginning near the inner, diverges and follows a sinuate course, 
ending much nearer the apex than the inner line, the distance varying; both wings 
speckled, sometimes thickly, with unusually large spots; outer edge of both wings 
deeply excavated, especially opposite the second median venule. Hind wings with 
no lines, only an obscure discal dot. Expanse of wings two and two-tenths inches. 
This moth ranges from Maine to Missouri. The larvais also described 
by Mr. 8S. H. Seudder as living on the black birch. But his description 
given inmy Monograph of the Phalenide (p. 530) is so different from Mr. 
Goodell’s that I fear it refers to a different insect.

6. THE CHESTNUT TREE-HOPPER. 
Smilia castaneew Fitch. 
Order HemMIpTeRA; family MEMBRACID2. 
Puncturing the leaves and extracting their juices in July, a triangular tree-hopper, 
shaped much like a beechnut, of a blackish color, tinged with green more or less when 
alive, its head and the anterior edges of its thorax and all beneath bright yellow, its 
fore-wings clear and glassy, with a blackish spot on their tips and another on the base, 
which is often prolonged along the middle of the wing and united with the hind spot. 
Length of male, 0.25; female, 0.30 inch. (Fitch.)
