especially the one on joint 2. Thoracic feet of joint 2 black,

 lescent, tubercles whitish. Very transparent, the blood watery, 

 the food in the stomach dark green. Stomach, dorsal vessel, 

 tracheae of both skin and stomach, sex glands (the elliptical, 

 subdorsal, situated in joint 9, the 9 a slender oblique cord in

 prominent; a long, thick horn arising between them, recurved a 

 little at the tip. Cases reaching the third abdominal segment, a 

 long slender tongue-case reaching back 21 mm. , or 5 mm. beyond

 eyes ; horn dark red ; a set of black dots on abdomen in the 

 normal position of tubercles i, ii and v of larva, a pair of dots 

 on prothorax and one on metathorax subdorsally. Exactly, the 

 abdominal black dots are thus: seg. i, tubercle ii; segs. 2 and 3, 

 tubercles i and ii; segs. 4-6, tubercles i, ii and v; seg. 7, tuber- 

 cles i and ii; seg. 8, tubercle ii, this spiracle obsolete, represented
