PUPAE OF SOME MAINE SPECIES OF NOTODONTOIDEA 65 



somewhat variable. The teeth on the furrow between the ninth 

 and tenth abdominal segments vary considerably, but in general 

 follow the same arrangement. The following table may serve 

 to separate the species : 



a. Prothoracic legs always extending as far caudad as the 

 maxillae, or meeting on the meson caudad of them ; 

 furrow between the ninth and tenth abdominal segments 

 with the teeth on the caudal margin all short and approxi- 

 mately of equal length ; pupae normally less than 20 mm. 

 in length. 



b. Dorsum of tenth abdominal segment not punctate ; caudal 

 margin of the furrow between the ninth and tenth ab- 

 dominal segments scarcely elevated ; surface usually 

 shining and polished. angusii. 



bb. Dorsum of tenth abdominal segment punctate as the 

 remaining segments except perhaps a small area near 

 meson ; caudal margin of the furrow between the ninth 

 and tenth abdominal segments always considerably 

 elevated ; surface dull. integerrima. 



aa. Prothoracic legs not extending as far caudad as the max- 

 illae, at least 1 mm. apart ; furrow between the ninth and 

 tenth abdominal segments with the teeth on the caudal 

 margin uneven, and longer near the meson; pupae nor- 

 mally over 20 mm. in length. 



b. Crest on the front with a prominent longitudinal carinate 

 ridge on the meson and a distinct furrow on each side; 

 abdomen with medium punctures ; each half of the cre- 

 master with three projections. major. 



bb. Crest on the front without longitudinal ridges or fur- 

 rows ; abdomen with large shallow punctures ; each 

 half of the cremaster with two projections.

Color bright reddish brown ; crest prominent, always ru- 

 gose with deep transverse striations and punctures, and usually 

 with two longitudinal furrows; face-parts and appendages with 

 transverse striations, much shallower than those of the crest
