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. infegerrima. 



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.

Fig. 5, D and E. 



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
