Papilla argynnuSj sp. n. 

 Papilio agamemnon, local form b, Wallace. 



Primaries the same as in specimens of P. agamemnon from 

 New Guinea ; secondaries entirely black, a very narrow 

 green streak extending from the costal margin to the middle 

 of the cell. The undersides of the primaries are identical 

 with those of P. agamemnon ; the secondaries reddish brown. 

 Expanse 4^ inches. 



Hab. K6 Island (Mus. Druce). 



Mr. Wallace obtained a single specimen of this species 

 from Ke Island, and considered it a variety of P. agamemnon. 

 I have five specimens before me that do not show any varia- 

 tion, and have little doubt it is a species peculiar to that 

 island. 



Heterocera. 



Fam. Sphingidse. 



Subfam. MAOBoaiossiN^. 



Pachygonia, Feld. 



Pachygonia ericea^ sp. n. 



Primaries dark greyish brown, crossed by numerous waved 

 lines of a darker brown ; a wide band of the same colour 

 crosses the wing from the costal margin to the anal angle, 

 beyond which are several greyish-white lunular-shaped 

 markings ; a submarginal black line, edged on the inner side 

 with yellowish brown, extends from the apex to the anal 

 angle : secondaries dark brown, with a large chrome-yellow 

 patch extending from the base to about the middle but not 

 touching the costal margin ; two narrow greyish-white lines 

 close to the anal angle. Underside dull brown, spotted with 

 whitish-brown markings near the apex of the primaries and 

 the anal angle of the secondaries. Head, thorax, abdomen, 

 and legs dark brown ; tegula3 darker brown, edged with 

 pale brown ; antennge reddish brown. Expanse 3 inches. 



Hah. Panama, Volcan de Chiriqui {Trotsch). 



This fine and very distinct species is in the collection of 

 Dr. Staudinger. It is not nearly allied to any species known 

 to me.
