72 CLARK — THIRTY-THREE NEW SPHINGIDAE [vS.'viil 



Panacra angulata sp. nov. 



Al. ant. long., d", 25 mm. Al. ant. lat., cf, 10 mm. Marg. ext., d\ 

 15 mm. 



Habitat. — Slopes of Mt. Korintji, southwestern Sumatra, 7500 ft. 

 altitude. August-September, 1921. C. J. and F. Pratt. Two males in 

 coll. B. Preston Clark (one the type) given me by my friend, Mr. J. J. 

 Joicey. There are other specimens in Hill Museum, Witley, Surrey, 

 England. 



Antennae brown. Palpus, first segment white, reddish brown along eye, 

 second segment white, reddish brown along eye and at apex. Head and 

 thorax brown. Mesothoracic tegulae deep brown. Legs reddish brown 

 with white scaling. Breast white, heavily irrorated with reddish brown. 

 Abdomen above light brown, with narrow dark brown median stripe. A 

 few blue scales at the segments. Abdomen laterally and beneath, warm 

 reddish brown, with prominent white lateral patches and a broad white 

 median stripe beneath. 



Fore wing above: Apex produced, distal margin concave from apex to 

 Rl, thence convex and undulate to hinder angle. Cilia black on veins, 

 yellow between them. Ground tone brown, with darker brown markings. 

 From a point on costal margin 7 mm. from the base a prominent line 

 extends 3 mm. directly toward hinder angle, at that point it is angled 

 sharply, and extends to inner margin, which it reaches 2 mm. from the wing 

 base. Small black stigma, surrounded by light blue scaling. Transverse 

 dark brown median line extends from a point 9 mm. distant from the apex 

 to a point 9 mm. distant from the hinder angle. Small dark cloud costally of 

 this line between Rl and R2. Narrow dark brown postmedian line extends 

 distally of the median one from inner margin to SC5, diverging gradually 

 from the median one, and sharply angled from SC5 to costal margin. A 

 lunulate line, with points distad on the veins, parallels the postmedian line, 

 and between the two is a third line, faint and also lunulate. A faint white 

 apical dot between apex and SC5. A prominent white dash between SC5 

 and Rl, extending obliquely basad from SC5 toward Rl. Veins Rl and 

 R2 are prominently dark brown from distal margin to lunulate postmedian 

 line; veins SC5, R3, Ml and M2 are less prominently so, and for a shorter 

 distance. Area between these veins somewhat darkened, as far as the 

 darkening of the veins extends. Dark brown semilunar area at hinder 

 angle, similar to that in P. mydon elegantulus.
