lb, ic present; ib simple; 3, 4, 5 from lower angle of cell; 6, 7 from upper angle; 

 7 anastomosing with 8 beyond cell. Male genitalia with uncus rudimentary or absent; 

 transtilla present; harpes with prominently developed clasper. 



PUPA (PL. 9, c-f) 



Moderately slender; abdominal segments gradually tapering; smooth except for 

 a slight rugosity on dorsum and a single row of 4 or 5 short spines on dorsum of abdomi- 

 nal segments i to 7; wings extending to or nearly to ventro-caudal margin of fourth 

 abdominal segment; cephalic end bluntly rounded, tapering from mesothorax; 

 epicranial suture present, represented by a straight line; vertex distinct, rather 

 narrow; labrum, pilifers, and maxillary palpi well developed; labial palpi small; 

 prothoracic and mesothoracic legs not extending cephalad between sculptured 

 eyepiece and antenna; maxillae long, extending nearly the length of the wings; 

 femora of prothoracic legs clearly indicated; prothoracic legs extending half the 

 length of the wings; mesothoracic and metathoracic legs extending to the tips of the 

 wings; antennae extending nearly the length of the wing; proleg scars plainly 

 visible on abdominal segments 5 and 6; mesothoracic spiracle with a strongly chiti- 

 nized caudal ridge, without setae; abdominal spiracle slightly produced; anal and 

 genital openings slitlike in both sexes; cremaster present, prominent, stout, spatu- 

 late, and armed at extremity with a cluster of 4 or 5 short curled hooks. 



LARVA (PL. 10, A-D; II, A, D-h) 



Cylindrical; moderately stout; abruptly tapering at caudal end. No secondary 

 hair. Legs and prolegs normal. Crochets triordinal, in a circle broken outwardly. 

 No anal fork. Prothoracic shield moderately broad, divided. Spiracles oval, 

 moderate; that on eighth abdominal segment slightly higher than those on ab- 

 dominal segments i to 7; no more than i}4 times as large; same size as that on 

 prothorax. Skin covered with fine granulations (PI. 11, E, F) especially strong and 

 dense on dorsum, diminishing toward venter and absent in folds marking the body 

 areas and a small space about the chitinized tubercles. 



Body setae moderately long; tubercles prominent, broadly chitinized; IV and V on 

 abdominal segments i to 8 under the spiracle and approximate; prespiracular shield of 

 prothorax small or moderate, nearly square, bearing only two setae (IV and V) situated 

 ventro-cephalad of the spiracle. III of prothorax absent; group VI bisetose on protho- 

 rax, unisetose on mesothorax and metathorax ; IV and V united on abdominal segment 

 9 and approximate to III; III directly in front of the spiracle on abdominal segment 

 8, over the spiracle on abdominal segments i to 7; III'^ present; group VII trisetose 

 on abdominal segments i to 6, bisetose on abdominal segment 7, unisetose on abdom- 

 inal segments 8 and 9; abdominal segment 9 with all setae in a vertical line, i absent; 

 on abdominal segments i to 8, II is latero-caudad of I; prothorax with IP higher than 

 I", dorso-caudad and remote from II**, closer to I"^ than to 11^, II** on the level of punc- 

 ture z; I^'equidistant from I" and puncture z, punctures x and y dorso-caudad of I", 

 distance between 1° and II" slightly greater than between I** and I". 



Head capsule spherical, nearly square in outline viewed from above, slightly wdder 

 than long ; greatest width at middle of head ; incision of dorsal hind margin not over one- 

 fourth the width of the head; distance between dorsal extremities of hind margin less 

 than one-half the width of the head; from dorsum of antennal ring a slight projection 

 of the epicranium forming an antennal shield (ATS). Frons broad, as long as or a 

 trifle longer than wide, reaching beyond middle of head. Adfrontal sutures extend- 

 ing to incision of dorsal hind margin. Longitudinal ridge (LR) short, less than one- 

 half the length of the frons. 



Ocelli six; lenses well defined. 



Epistoma normal.
