[YOU VIII. 
tooth elevated and directed cephalad. Maxillae (mx) short, subtrian- 
gular with slight extensions at the cephalo-lateral angles, apices 
rounded and slightly divergent. 
THOEAX.— Prothorax (p) coarsely punctate or rugose except for 
smooth median area, anterior margin transverse, posterior margin 
arcuate. 
Mesothorax (ms) posterior margin broadly rounded, width nearly 
4 times prothorax and 7 times metathorax. Mesothoracic spiracle 
(msp) within a deep slit in the pro-meso-thoracic suture at its lateral 
extremity. 
Metathorax (mt) frd width of 1st abdominal segment. Legs 1st coxa 
elongate with a sharp transverse ridge or tooth near the apices of the 
maxillae ; 1st tibia—tarsus extending slightly beyond apex of 1st coxa ; 
2nd coxa short, separating the 1st legs ; 2nd tibia—tarsus longer than 
1st, apices in contact; 3rd coxa invisible ; tips of 3rd tarsi visible between 
apices of forewings. Wings, forewings (w x ) extending caudad as far as 
suture of 3rd and 4th abdominal segments, distal margins in contact; 
hindwings (w 2 ) covered except for a narrow strip along the dorso-basal 
margin. 
ABDOMEN.—FEMALE with segments 7, 8, 9, and 10 fused together ; 
MALE with segments 8, 9 and 10 fused; remaining segments in both 
sexes moveable. 
Flanged plates (fpl) well developed composed of a transverse row 
of numerous large teeth, directed caudad, concavely excavate below, 
ribbed and buttressed above; FEMALE with one complete row on 
segment 1, two complete rows on segments 2—7 and one incomplete 
row on segment 8, the anterior row more strongly developed than the 
posterior row on the Same segment. Segment 1 with one posterior row 
feebly developed extending almost to wings ; segment 2 with posterior 
row slightly longer than anterior extending nearly to spiracle; segment 
3 with anterior row slightly longer than posterior extending nearly to 
spiracle ; segments 4—7 with anterior row extending to ventro-lateral 
margin of segment, posterior row not reaching the level of spira cle; 
segment 8 with dorsal part of anterior plate very feebly developed and 
separate, or entirely absent, lateral part, highly developed, extending 
to ventro-lateral line. MALE with one complete posterior row on 
segment 1, two complete rows on segments 2—8, segments 1—7 as 
in female ; segment 8 with anterior row complete to ventro-lateral 
margins, posterior row short dorsal.* 
* Beekman [1919, p. 8] describes the pupa faithfully, but from his remarks 
on the 8th segment in the text and footnote it is probable that his specimens were all 
males.
