19 IS] Pupce of Common Sphingidce 433 



There are seven species of Pholus in North America but only 

 two of these are common in the east. These species may be 

 separated as follows: 



a. Head longer than broad as seen in lateral view, the distance from the cephalic 

 margin of the glazed eye to the anterior end of the l)ody three times or more 

 the length of the eye-pieces P. achemon 



aa. Head broader than long as seen in lateral view, the distance from the cephalic 

 margin of the glazed eye-piece to the anterior end of the body twice the 

 length of the eye-pieces P. satellUia pandorus 



Pholus achemon Dru. (Fig. 7). 



Proximal part of maxillae, head and thorax roughened with indeter- 

 minate transverse striations, or often somewhat granular, the appen- 

 dages usually smooth and polished, abdominal segments coarsely 

 densely punctate on the cephalic margin, but more sparsely punctate 

 on the remainder; head noticeably narrowed as seen in ventral view; 

 in lateral view the distance between the cephalic margin of the glazed 

 eye-piece and the cephalic end of the body is at least three times the 

 length of both eye-pieces; antennae scarcely tuberculate, sometimes 

 with a minute, mesal row on the proximal half, a little longer in the 

 male, extending to, or slightly beyond, the distal ends of the prothoracic 

 legs; portion of prothoracic femur exposed about 4 mm. long and 1 mm. 

 wide; annulets seldom distinct on the abdominal segments; scar of 

 caudal horn smooth and pohshed; cremaster rugose 2-3 mm. long, 

 longer than broad, but variable as to breadth. Length of pupa 50-65 

 mm., greatest width 12-13 mm. 



Pholus satellitia pandorus Hbn. 



Body stouter than in P. achemon, head not so much narrowed as 

 seen in ventral view, in lateral view the distance from the cephalic 

 margin of the glazed eye-piece to the end of the head is dbout twice the 

 length of the eye-pieces; head, thorax and usually the appendages 

 roughened with striations and impressed lines, soinetimes finely gran- 

 ular, abdominal segments coarsely punctate, more densely punctate 

 along the cephalic margin; antennae usually smooth, sometimes with 

 minute tubercles mesad of the median line, longer in the male extending 

 to, or in some male specimens one-third of the distance between the 

 distal ends of the prothoracic and mesothoracic legs; annulets usually 

 distinct on the dorsum of the abdominal segments ; cremaster triangular, 

 variable as to width, ending in a sharp point which is somewhat 

 bifurcate. Length of pupa 52-65 mm., greatest width 14-15 mm. 



Genus Ampeloeca R. & J. 



The pupae of this genus belong to the small number among 

 lepidopterous pup^ which are not dark brown or black, but 

 instead a very light brown or coffee color with darker markings. 

 They are not of the typical sphingid shape but rather blunt at 

 the cephalic end, and the labrum is always on the ventral
