OXYAMBULYX. 125 



Filial instar. Shape as in others of the genus except that 

 the horn is slightly up -curved. Surface smooth, the transverse 

 rows of tubercles very low ; very small white tubercles on 

 ventral surface. 



Coloration. — Head greyish-green with a whitish line on 

 each side of the dorsal line from vertex to apex of 

 clypeus, and a white stripe separating face from cheek ; 

 a small orange -coloured tubercle on the apex of each lobe ; 

 a whitish subdorsal stripe from each tubercle to the nape, 

 joining the subdorsal stripe of the body ; apex of clypeus 

 reaching to two-fifths length of head. Body yellowish- 

 green above the spiracular line, greyish-green below it ; a 

 white, clearly defined subdorsal stripe on segment 2, becoming- 

 yellow dorso-laterally, and less clearly defined on the posterior 

 segments ; a narrow, yellow, subspiracular stripe from the 

 front margin of 2 to hinder margin of 4, where it meets the 

 oblique stripe on 5 at its lower end ; seven yellow oblique 

 stripes on 5 to 11 ; on the median segments the angle between 

 the oblique stripes and the dorso -lateral stripe filled in with 

 pale violet triangular patches, these patches often bordered 

 with rusty-red or rusty- brown colour, which may spread so. 

 as to cover the whole body excepting the triangular patches. 

 Spiracles oval, yellowish-grey with a reddish tinge, the central 

 slit shaped like a candle-flame and dark greyish -brown. 

 Length about 70 mm. 



Pupa. — The shape the same as in others of the genus ^ 

 Surface superficially shagreened, especially on the dorsum ; 

 sculpturing on segment 4 a transverse subdorsal raised line, 

 the two lines sometimes meeting on dorsum where the junction 

 forms a short shining streak. Cremaster longer than broad, 

 flat dor sally and finely rugose, the tip a transverse shortly 

 oblong piece with a small bristle or tooth at each lateral corner. 

 Length 36-44 mm. ; breadth 12 mm. 



Habits. — Food-plant : Poupartia Fordii Hemsl. (= Spondias- 

 axillaris Roxb.), family Anacardiacese (in China) ; a specimen 

 was caught at rubiaceous flowers with a <j> 0. sericeipennis , 

 which seems to indicate that these two species feed.
