a. Body setae very long and heavily chitinized, often as long as the seg- 

 ments of the abdomen, and, as seen under high power, usually forked 

 at the apex ; f ronto-clypeal suture curving eephalad from the proxi- 

 mal ends of the antennae to the cephalic margin of the body; ci'e- 

 master always present; dorsal cephalic margin of segments two, 

 three, and four of the abdomen with a slight rounded projection on 

 each side of the meson, edged with a dense fringe of whitish setae di- 

 rected eephalad, caudad of this a prominent elevation bearing a sim- 

 ilar fringe of setae on the summit (Fig. 91), 



b. Dorsal surface of the cephalic margin of the movable segments 

 with a prominent cavity on the meson having heavily chitinized 



edges TricliotapJie Clemens. 



bb. Dorsal surface of cephalic margin of the movable segments with- 

 out any cavity; a strongly chitinized ridge separating the ce- 

 phalic margin from the remainder of the segment, eephalad of 

 this a band of short spines, then a prominent furrow, the furrow 

 and the remainder of the cephalic margin being deeply punctate. 



Ypsoloplius Fabricius. 

 aa. Body setae never modified ; segments two, three, and four of the ab- 

 domen never as described in a. 

 b. Entire body with a dense covering of whitish setae visible to the 

 unaided eye, giving the pupa a furred appearance, 

 c. Maxillary palpi long, reaching the proximo-lateral angles of the 

 maxillae; antennae lying adjacent on the meson for about two 

 fifths of their length; cremaster short and blunt, the end set 

 with about eight stout curved setae ; length 8-10 mm. 



Anacaynpsis Curtis. 



cc. Maxillary palpi short, never reaching the proximo-lateral angles 



of the maxillae; antennae just meeting on the meson; cremaster 



with a sharp point curved dorsad, with curved setae at the sides 



and base ; length 5-6 mm Aristotelia (a)Hiibner, 



bb. Entire body never covered with setae. 



c. Seventh abdominal segment with a dense fringe of setae on some 

 portion, 

 d. Fringe of setae confined to the cephalic and lateral edges of a 

 prominent lateral cavity. 

 e. Body smooth, not depressed ; cephalic edge of the lateral cav- 

 ity trilobed (Fig. 93) Evippe Chambers. 



ee. Body with small spines, strongly depressed ; cephalic edge 



of the lateral cavity bilobed Telpliusa Chambers. 



dd. Fringe extending around the segment or nearly so, 



e. Fringe extending around the segment in a straight line ; body 

 not noticeably depressed, the surface smooth. 



Recurvaria (a) Haworth. 

 ee. Fringe extending around the segment in a more or less wavy 

 line; body noticeably depressed and very broad in the 

 thoracic region, surface with punctures or spines.
