When about to transform it bores through the pitch wall and escapes, 

 leaving the pupa skin protruding. 



The 7noth (female) expands 1.2 inch. Fore wings opaque; hind 

 wings transparent. Color blue black as follows : fore wings, the clothed 

 portions of hind wings, head, palpi, thorax, upper part of abdomen, 

 antennae and legs. The neck fringe and the sides of the collar are orange, 

 also the ventral side of the abdomen and the tail fringes. The antennae are 

 long, slightly enlarged toward the end ; there is a decided orange line on 

 the under side of the antennfe for one-third their length ; the tarsi are 

 smoky. The male not seen. 



Aegefia pidipes G and R. 



I have found this species common enough at Buffalo wherever there 

 are old plum trees. In some instances I have found it doing grave injury. 

 It works also in the cherry trees. Its history has been given recently by Dr. 

 J. S. Bailey (North Am. Ent, I, 17) with so much exactness that any 

 further notice here seems unnecessary. I make mention, however, of 

 finding pictipes in the wild black-cherry {Pruniis serotina) and the wild 

 red-cherry {P. Pennsylvanica) in June and July last, at Hastings Center, 

 N. Y. Numerous larvae and pupje were taken from ben^th the bark ; 

 imagines were taken flying about the trunks. 



Aegeria acerni Clemens, likewise has been carefully described by Mr. 

 C. V. Riley in the Mo. Ent. Rept., vi., 107. He says, however, that the 

 pupa is unarmed, which is not the case with those obtained here, if 

 "unarmed " refers either to the dorso-abdominal te^th or to the corneous 

 pointed clypeus. The larvae of this moth are annually doing much 

 damage to the hard maples {Acer sacchantmm), planted so generally in 

 this city for shade ; they are less destructive to the soft maple {A. riibrum). 

 It appears that they seldom attack uninjured trees, but depend upon acci- 

 dents to afford them opportunity to enter the inner bark and superficial 

 wood : when once established they keep at the scar or wound year after 

 year,' thus preventing recovery and causing the trunks to become rough 

 and unsightly ; in many cases the trees are thus almost ruined. The moths 

 appear most numerously from May 20th to June 15th. I have not been 

 able to find, after patient search, this borer in our forest maples. 



Exitiosa and iipidiformis are both sufficiently abundant in this vicinity 

 to be destructive to peach tree and currant bush. I have imagines of the 

 former which escaped late in September from chrysalids given me by Mr.
