uing of August, at which time I have repeatedly taken them in the 

 winged 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 caterx)illar 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, N. T., 

 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 iinotata Say. 



Order Hemiptera ; family Membracid^. 



Puncturing the leaves and extracting their juices from July till the end of 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 .:50 inch. (Fitch.)
