1918] PupCB of Common Sphingidce 435 



the segments. As far as other characters are concerned, it 

 resembles Deidamia most closely, as it has a low tubercle 

 mesad of each eye-piece and the proximal part of the maxilla 

 prominently excurved, but scarcely carinate. Each mandibular 

 area has a low, indistinct tubercle which is visible in ventral 

 view. The maxillae extend to the caudal margin of the wings. 

 A small portion of the prothoracic femur is exposed. The 

 antenna are similar in the sexes. The scar of the caudal horn is 

 more rugose than the remainder of the segment. The cremaster 

 is triangular and sharply pointed. This genus includes a single 

 species D. pholus. The species has been commonly known in 

 this country as Ampelophaga chcerilus. 



Darapsa pholus Cram. 



Color light brown to darker brown, mottled with darker brown or 

 black, somewhat resembling the coloring of Ampeloeca species, spiracles 

 and conjunctiva black; entire surface of body dull and roughened with 

 wavy impressed lines, the sculpturing deeper on the head, thorax and 

 appendages; abdominal segments 5-6 with two or three interrupted 

 rows of spines on the dorsimi, becoming a single row near the spiracles, 

 segment 7 with one row on the dorsimi, but more near the spiracles; 

 the spines very small on the ventral surface ; annulets faintly indicated 

 on the dorsum of segments 1-3 ; segments 8-9 punctate, the ninth seg- 

 ment almost smooth; antennae almost smooth, without prominent 

 tubercles, extending a little farther caudad than the prothoracic legs; 

 portion of prothoracic femur exposed about 1.5 mm. long and .5 mm. 

 wide; cremaster rugose, about 3 mm. long, triangular, longer than broad, 

 usually slightly curved and ending in a sharp point. Length of pupa 

 35-37 mm., greatest width 9 mm. 



Genus Sphecodina Blanch. 

 The pup£e of this genus have a longer cremaster in propor- 

 tion to their size than most other pupae of the family except 

 Amphion, where it is twice as long as broad. The body is 

 sphingiform but stout, with the labrum visible in ventral view. 

 The maxillae extend to the caudal margin of the wings. The 

 antennae are similar in the sexes and are a little wider on the 

 cephalic half. The metathorax has a transverse furrow extend- 

 ing about half-way across the segment. The scar of the caudal 

 horn is always easily distinguished. The cremaster is triangular, 

 and pointed at the distal end, with length and breadth 

 approximately equal.
