PUPAE OF SOME MAINE SPECIES OF NOTODONTOIDEA 63 



and there makes an earthen cell. The pupa is easily recognized 

 by the peculiar "bordered" appearance of the abdominal seg- 

 ments. 



Genus HARPYIA Ochsenheimer. 



Body distinctly depressed, elliptical in outline; front elevat- 

 ed at meson to accommodate the slight crest of the adult ; f ronto- 

 clypeal suture indicated laterad by a slight furrow ; imaginations 

 for the anterior arms of the tentorium large and distinct ; clypeo- 

 labral suture indicated by a furrow; labrum nearly as long as 

 broad, the caudal margin slightly narrowed; genae elevated; an- 

 tennae elevated with the proximal half almost twice the width 

 of the prothoracic legs, then rapidly narrowing to about one- 

 fourth of this width, ending slightly caudad of the prothoracic 

 legs ; maxillae one-third the length of the wings ; prothoracic 

 and mesothoracic legs of the usual length and both meeting on 

 the meson caudad of the maxillae ; wings meeting on the meson 

 caudad of the mesothoracic legs ; mesal length of the prothorax 

 slightly more than half that of the mesothorax, and that of the 

 metathorax one-sixth that of the mesothorax; abdominal seg- 

 ments punctate; no cremaster present. 



HARPYIA BOREALIS Boisduval. 

 Fig. 5, J. 



Color reddish or yellowish brown ; surface smooth and dull ; 

 head, thorax and appendages with fine striations more promi- 

 nent on the prothorax and front ; antennae with a row of minute 

 tubercles along the middle line; maxillae with the proximo- 

 lateral angles separated from the eye-pieces by a distance equal 

 to the width of the eye-pieces; prothorax with a protuberance 

 at each cephalo-lateral angle, probably indicating the scar of 

 larval protuberances ; mesothoracic spiracle slit-like ; abdomen 

 finely, sparsely punctate on the dorsum of the first eight seg- 

 ments, the remainder of the surface smooth ; spiracles lenticular, 

 usually margined by a black line. 



Length 16 to 18 mm.; greatest width 7 mm. 



The larvae of this species have been taken in Maine from 

 poplar.
