M 1923 2 ] CLARK — THIRTY-THREE NEW SPHINGIDAE 73 



Fore wing beneath: Cilia as on upper side. Ground tone yellow, heavily 

 irrorated with reddish orange. Median dark brown line similar to that on 

 wing above, with dark shade basad of it, the three postmedian lines of the 

 wing above faintly duplicated in reddish orange, as are the heavy brown 

 markings along and between the veins distally. These have the appear- 

 ance of fingers, with their tips on distal margin. 



Hind wing above: Cilia as in fore wing. Distal margin undulate. 

 Ground tone brown. Light red submarginal band extends from anal angle 

 to R2, broadening to that point; irregular brown line within this area, 

 roughly parallel to distal margin. Blue scaling along distal margin from 

 anal angle to R3. 



Hind wing beneath: Ground tone yellow, heavily irrorated with red- 

 dish orange. Median basal area light blue, extending along veins SC5, Rl 

 and R2 to distal margin, along R3, Ml and M2, half way to distal margin. 

 This light blue area is continuous between Rl and R2, and broadens out 

 to become a submarginal band extending broadly from inner margin to 

 R2, and then narrowing to hinder angle. Between this submarginal band 

 and distal margin the reddish orange color reappears narrowly. Three 

 dark brown lines, one antemedian, one median, and one postmedian, ex- 

 tend irregularly from inner to anal margin. 



A brilliant insect, nearest to P. mydon elegantulus Her.-Sch. 



Nephele joiceyi sp. nov. 



Al. ant. long., d\ 44 mm. Al. ant. lat., d\ 18 mm. Marg. ext., d\ 

 24 mm. 



Habitat. — Slopes of Mt. Korintji, southwestern Sumatra, 7300 ft. 

 altitude, August-September, 1921. Collected by C. F. and J. Pratt, and 

 given to me by my friend, Mr. J. J. Joicey. Two males (one the type) in 

 coll. B. Preston Clark. There are also specimens in Hill Museum, Witley, 

 Surrey, England. 



This insect is allied to N. didyma Fabr., but is clearly distinct. 

 It is larger. 



Coloration similar to that of N. didyma. Palpus, breast and lateral line 

 extending from the eye to base of fore wing, more prominent than in N. 

 didyma. 



Fore wing above: Darker brown than in N. didyma, with a prominent
