PUPAE OF SOME MAINE SI-HOES OF NoTODONTOlDEA 43 



Average length 9 mm.; greatest breadth 3 mm. 



The larvae of this species are easily recognized by the 

 group of four filaments that stand up on the back with their 

 ends slightly curled. The first pair is attached to the second 

 abdominal segment. They feed on various plants and were col- 

 lected at Orono on sweet fern during the first week in August. 

 The larvae pupated the fifth of August between the leaves of 

 sweet fern, but did not form a cocoon. 



Genus CINGILIA Walker. 



Body slender, but of usual type; labrum quadrangular; a 

 small polygonal portion of labial palpi exposed caudad of the 

 labrum ; antennae extending to the caudal margin of the wings, 

 their greatest width greater than that of the prothoracic legs, 

 their distal ends usually meeting on the meson; maxillae almost 

 reaching the caudal margin of the wings, the proximo-lateral 

 angles not extending laterad to the eye-pieces ; prothoracic legs 

 three-fourths the length of the wings, their femora never ex- 

 posed ; mesothoracic legs seven-eighths the length of the wings ; 

 only the prothoracic leg extending cephalad between the sculp- 

 tured eye-piece and the antenna ; mesal length of prothorax two- 

 lifths that uf the mesuthurax : metathorax about half the length 

 of the prothorax and slightly shorter than the first abdominal 

 segment; abdominal segments with shallow, transverse im- 

 pressed lines ; dorsal furrow between the ninth and tenth ab- 

 dominal segments present, the caudal margin crenulate ; cre- 

 master without a furrow at the base, ending in two long hooked 

 spines with one short hooked seta on each side, a transverse 

 row of four similar setae just cephalad of these. 



This genus includes a single species in America.

Color white with conspicuous black blotches, the largest 

 of these on the dorsum of the first five abdominal segments, the 

 wing veins and some of the sutures lined with black; entire 

 surface of body with shallow transverse impressed lines; an- 

 tennae elevated, highest along the middle line, transversely lined 

 with black ; mesothoracic spiracles split-like ; abdominal spira-
