This pretty species may be recognized by its white body and wings, and 

 four deep golden-ochreous costal spots, with usually a basal and extradiscal 

 line. The lines are often wanting; and, in one example received from Mr. 

 Lintner, there arc only two (third and fourth) costal spots and faint traces of 

 a common line. 



Larva. — "The larva of this little delicate-looking geometric moth feeds 

 on the maple. It is common in our neighborhood, and may be readily got, in 

 season, by striking the branches of the frees a sharp blow, when it drops at 

 once part way to the ground, remaining suspended by a silken thread, by 

 means of which, when danger passes, it can regain its position on the tree. 

 It is found full-grown about the middle of June, enters the chrysalis state 

 within a i'rw day:; afterwards, and produces the moth early in July. 



"When full-grown, the larva measures about five-eighths of an inch in 

 length, body cylindrical.
