204 SPHINGID^]. 



and surrounded by an ocellus-like marking, dark green ringed 

 with crimson. Head 9 mm. long by 3-5 mm. broad. 



5th instar. Head very large and heavy, elongate-triangular 

 in shape, vertex rounded and dorsal line shallowly impressed ;. 

 the processes represented by a flat tubercle on apex of each 

 lobe ; true clypeus about one -fifth length of head, apex 

 acute, basal angles rounded and tumid ; false clypeus a very 

 narrow strip outside true clypeus ; labrum one-third length 

 of clypeus and slightly broader than clypeus, with a ridge 

 on each side of the dorsal line, the lateral ends tumid ; ligula 

 as long as broad, the deep triangular sinus having a narrowly 

 rounded lobe on each side ; eyes with the line joining 1 and 2 

 at right angles to the straight line joining 3, 4 and 6 ; 1 and 

 2 about one eye-diameter apart, 3 about two diameters from 

 2 and 4 ; 6 about three diameters from 4 ; 5 level with and 

 about two diameters from 4 ; eyes 1 and 2 situated on a tumi- 

 dity. Surface of head slightly shining, set sparsely and 

 irregularly with minute tubercles. Body short and stout ; 

 the vertex of the head rises high above segment 2 and the 

 segments increase in diameter gradually to 8, then decrease 

 gradually to 12. Horn short, stout, straight, tapering 

 gradually to a blunt point, and held horizontal or directed 

 slightly downwards, touching or nearly touching dorsum of 

 anal flap ; anal flap and claspers tumid and heavy. Surface 

 of body dull ; a transverse row of small pointed tubercles 

 along each secondary ring ; a line of larger sharply-pointed 

 tubercles on each side of dorsal line from front margin of 

 segment 2 to base of horn, these tubercles gradually increasing 

 in length to near base of horn ; a line of pointed tubercles 

 along each oblique stripe, the tubercles on the oblique stripes 

 of 5 and 11 larger than the rest ; those on the oblique stripe 

 of 10 the smallest ; the line of tubercles on each segment runs 

 forward on to the adjoining segment, and backwards to near 

 the dorsum of the segment behind, that on 1 1 running across 

 12 to base of horn. Large rounded tubercles on horn, anal 

 flap and claspers ; all the tubercles mentioned setiferous ; 

 the subdorsal and dorso-lateral main hairs are not distinguish- 

 able, but there are long and extremely fine supra- and sub- 

 spiracular hairs, and some hairs on true legs, on shanks of 

 prolegs and on edge of clasper-face. 



Coloration. — Head : face bluish-green, cheek pale green ; a 

 whitish stripe, edged on the inner side with green, from apex 

 of each lobe to base of antenna, separating face from cheek : 

 a green dorsal stripe from vertex to nape ; tubercles white ; 

 labrum pale green ; ligula brown with a pale green stripe down 

 each lobe ; basal and middle segments of antenna greenish, 

 end-segment greenish with brown tip ; mandible pale green, 

 tip dark brown. Body varying from pale apple-green to
