ning of August, at which time I have repeatedly taken them in the 
wiuged state ; but the greater part pass through their last change in 
June." I have observed the full-grown caterpillar at Brunswick, Me.,

the first and second weeks in August; they spin from the middle of 
August till September. The following description of the caterpillar is 
taken from my notes: 
The caterpillar.— Head of moderate size ; body cylindrical, rather short and not 
very convex; each segment with four tubercles above, two smaller median ones 
being situated in front of and between two latero-dorsal larger ones ; three tubercles 
on each side of each segment, all giving rise to dense verticils of long, uneven fox- 
yellow hairs ; most of the hairs as long as the body is thick, while others on the back 
are twice as long, so that in outline the larva is an elongated ellipse, the head and 
tail being alike concealed by the spreading hairs. The body and head is black or 
yellowish mottled with black. The hairs are tawny yellow, while the short hairs on 
the sides of the thoracic rings are black. 
The moth. — Snow white, with a black dot in the middle of the fore- wings and two 
on the hind wings; a row of black spots along the back of the abdomen and a row 
along the sides ; between the latter dots a longitudinal deep yellow stripe; the basal 
joints of the fore-legs are yellow. The wings expand about 2 inches. The eggs are 
said by Harris to be golden yellow, and to be laid in patches on the leaves of plants.

9. Paria aterrima. (Olivier.) 
This insect in the imago state, Mr. W. L. Devereaux, of Clyde, K r., 
writes us, " preys upon the foliage and flower-buds of the butternut." 
Mr. Chittenden also writes to the same effect. 
10. The two-marked tree-hopper. 
Enchenopa oinotata Say. 
Order Hemiptera ; family Membracid^e. 
Puncturing the leaves and extracting their juices from July till the endof the 
season, a small rusty brown or black tree-hopper, with two bright pale yellow spots 
upou its back, which part is prolonged forward and upward into a compressed horn 
rounded at its tip and giving the insect a resemblance to a little bird with an out- 
stretched neck, and the four forward shanks broad, thin, and leaf-like. Length, .25 
to .:*0 inch. (Fitch.)
