PUPAE OF SOME MAINE SPECIES OF NOTODONTOIUEA 69 



highly polished and without punctures; punctures on the front 

 black, and more irregular in outline than on the remainder of the 

 body surface; mesothoracic spiracles with both margins elevat- 

 ed, the caudal margin slightly more so than the cephalic, and 

 black in color; movable abdominal segments with the cephalic 

 margin more densely punctate than the remainder and with large 

 lunate punctures; cephalic margin separated from -the remainder 

 of the segment by a distinct ridge, and just caudad of this a row 

 of large black punctures ; abdominal spiracles (Fig. 6, B) elevat- 

 ed along the cephalic margin, the openings somewhat crescent- 

 shaped and directed caudad ; cremaster less than 1 mm. in length, 

 rugose with longitudinal ridges, each point of the bifurcation 

 bearing three hooked setae. 



Length 17 to 21 mm.; greatest width 5 to 7 mm. 



The larvae of Symmerista albifrons are striped longitudin- 

 ally with black and red and have a prominent red hump near 

 the caudal end of the body. They spin a thin, tough cocoon 

 between leaves, and are usually found on the surface of the 

 ground under the tree on which the larvae fed. The larvae feed 

 on oak and maple. They appear late in the season and pupate 

 in September. 



Genus SCHIZURA Doubleday. 



Body of usual type, sometimes with a projection at the 

 cephalic end ; surface appearing smooth and polished ; epicranial 

 suture visible in some species ; antennae with the greatest width 

 greater than that of the prothoracic legs, narrowed rapidly and 

 forming a long pointed tip, never quite reaching the caudal mar- 

 gin of the wings ; maxillae always more than three-fifths the 

 length of the wings, but never reaching their caudal margin, 

 the caudo-lateral angles always reaching the glazed eye-piece, 

 sometimes extending beyond ; mesal length of prothorax one- 

 half that of the mesothorax; mesonotum with a row of deep 

 elongate pits along the caudal margin of the wings with smooth, 

 square black areas between; metathorax with its mesal length 

 about one-fourth that of the mesothorax ; abdomen with the first 

 eight segments punctate; cremaster entirely bifurcate, each half 

 somewhat boot-shaped, the lateral margins of the cremaster 

 subparallel.
