some butterfly in form not unlike the Graptas. The general 

 coloi' of the upper side of the wings is reddish maroon, the border 

 is nankeen, while the spots just inside the border are blue. The 

 under side of the wings, shown on the right of the figure, is 

 mottled with grey, bhick and white. There are two broods each 

 season. The first comes from eggs laid in early spring, and 

 reaches maturity in July. These lay their eggs, and from them 

 comes a second brood in August or early in September and these 

 last, as has been noticed, remain until the following spring. This 

 species is one of the few found in both this country and Europe. 

 The larvae are not usually very destructive, but sometimes they 

 are sufficiently numerous to do much mischief. A very interest- 

 ing fact in connection with this insect is found in the stridulation 

 produced liy the wings. Very few of the moths and butterflies 

 are known to make any sound whatever, but it has been noticed 

 in a few species that a more or less distinct noise was produced 

 by them when in company with each other. The sound produced 

 by Vanessa antiopa is a grating or scraping sound, and an exam- 

 ination of the fore wings shows an apparatus for producing the 

 sounds which are made by rubbing the fore wings over the hind. 



Of the Hawk moths or Sphingidae there are three species that 

 have been found feeding on the ehn, though none are troublesome 

 as a general thing. 



A very fine Hawk moth, 



Smcrinthus cxccecatus^ S. and A. 



is found in the larva state on many trees, among them the elm. 

 The front wings are richly shaded with fawn color and brown. 

 The hind wings are of a beautiful shade of rose color in the 

 middle, and bear an eye-like spot the center of which is pale blue. 

 The caterpillar is about two inches and a half long, of a green 

 color, obliquely marked on the sides with white or pale yellow. 

 The whole body is covered with light granulations. It is not 

 common enough to be very injurious. 



Sineruithus geviinaius^ Say, 



A moth about two inches and a half across the spread wings, 

 is a pretty soft-hued moth of a grayish color on the front 

 wings while the hind wings are very prettily touched with 

 red and bordered with gray. The larvae is light green', with 

 a curved horn on the caudal portion of the body. The surface of
