Pupae of Some Maine Species of Notodontoidea 75 



the sculptured eye-piece and the antenna ; antennae about seven- 

 eighths the length of the wings, the distal end of each curved 

 slightly laterad, widest at the cephalic end where they exceed the 

 greatest width of the prothoracic legs and narrowed gradually 

 to half this width at the distal end ; maxillae slightly more than 

 one-third the length of the wings, the proximo-lateral angles 

 never extending to the eye pieces ; labial palpi entirely concealed ; 

 prothoracic legs three-fifths the length of the wings, the distal 

 third of their length meeting on the meson caudad of the max- 

 illae ; mesothoracic legs about five-sixths the length of the wings, 

 and meeting on the meson caudad of the prothoracic legs for 

 about the same distance ; tips of- the metathoracic legs showing 

 on the meson between the wings ; metathoracic wings exposed 

 on the ventral surface, meeting on the meson just caudad of the 

 mesothoracic wings and extending along the mesal margin of 

 the mesothoracic wings to their caudal margin, and visible most 

 of the way across to the lateral margin ; prothorax with a prom- 

 inent ridge on the meson, visible in ventral view ; mesal length 

 of prothorax two-fifths that of the mesothorax ; mesothoracic 

 spiracles slit-like ; metathorax shorter than usual, its mesal 

 length one-sixth that of the mesothorax ; abdominal segments 

 1 to 8 with medium sized punctures and sparsely covered with 

 small curved spines which are more numerous near the spiracles 

 and the scars of the ventral prolegs, the transverse conjunctiva 

 covered with small spines or spinous processes ; body setae aris- 

 ing from the bases of the larger spines ; dorsal furrow present 

 between the ninth and tenth segments ; abdominal spiracles 

 slightly sunken, lenticular in outline, the openings elliptical ; 

 cremaster triangular in outline, longer than broad and ending in 

 a group of stout hooked setae. 



This genus includes a single species, Falcaria bilineata, 

 found throughout the Atlantic states.

Color dark brown, but covered with dense, rather flocculent, 

 whitish bloom ; head, thorax and appendages considerably rough- 

 ened with indeterminate, transverse impressed lines ; labrum 

 somewhat quadrangular, the caudal margin slightly notched ;
