MACROGLOSSUM. 377 



toothed ; eyes with 1 to 4 in a slight curve, about two eye- 

 diameters apart ; 6 in line with 3 and 4 and rather more than 

 two diameters from 4 ; 5 about three diameters from 6, 

 rather less from 4 ; surface of head dull and smooth. Body 

 dull and smooth ; horn straight, long, base stout, tapering 

 evenly to a point, covered with small tubercles and rising 

 from a conical tumidity. 



Coloration. — Head green, suffused lightly with glaucous ; 

 an obscure yellowish subdorsal stripe, and a similar stripe 

 separating face from cheek ; labrum pale glassy-green ; 

 ligula similar, but sinus edges opaque white ; basal segment 

 of antenna green, other segments red ; mandible green, 

 tip narrowly dark reddish-brown. Body bright grass-green, 

 dotted with white ; a narrow yellow dorso-lateral stripe from 

 segment 2 to near base of horn, wanting on 5 ; white oblique 

 stripes on 5 to 11, obscure on 5, broad on 11, narrow on 12 

 to base of horn, the lower part of each stripe formed of short 

 grey lines ; horn with dorsal surface dull green, sides of basal 

 half china -white with a bluish tinge, tip orange, the tubercles 

 black on the green portion, white on the white portion and 

 orange near the tip. Spiracles oval, flush, white suffused 

 on each side of the central slit by reddish-brown. 



There is also a dark- coloured form in which the head is 

 green with pink reticulations, and a brown subdorsal stripe ; 

 segments 2 to 5 brown ; remaining segments olive -brown, 

 dorsum pinkish -brown ; an olive -brown dorsal stripe ; the 

 dorso-lateral stripe yellow on 2 to 5, olive-brown on remaining 

 segments ; seven pinkish-brown oblique stripes on 5 to 11, 

 edged below by olive-brown, and that on 11 becoming white 

 where it crosses 12 to base of horn ; horn fuscous with yellow 

 tip. There are other forms intermediate in shade between 

 the two described above. Length 55 mm. ; breadth 8 mm. ; 

 horn 6 mm. 



Pupa. — Tongue -sheath projecting considerably in front of 

 head, semi-elliptical in profile ; tip of tongue spatulate ; 

 antenna reaching to nearly the middle of wing-case, fore leg 

 slightly shorter. Surface shining ; head, thorax and wing- 

 case smooth ; abdomen coarsely pitted with coalescent pits 

 except on hind bevels of segments 8 to 10 ; front bevel of 

 9 with seven or eight irregular short ridges, the anterior ridge 

 the most prominent, ridges becoming shorter and less promi- 

 nent backwards, a long channel reaching from dorso-lateral 

 to ventro- lateral region in front of the anterior ridge. Spiracle 

 of 2 as in pupa of insipida ; remaining spiracles oval, flush, 

 the central slit with narrow raised edges. Cremaster triangular, 

 tip truncate, a short tubercle at each lateral angle of the trunca- 

 tion, venter hollowed longitudinally, a central keel at base 

 dividing into two parallel arms which do not reach the tip,
