180 Mr. L. B. Prout on 
anteriorly ; a small white apical patch, terminating at SC’, 
where it attains a measurement of 3 mm. 
Fore wing beneath coloured much as in madilliz, subapical 
patch much more irrorated (in the paratype obsolescent) , post- 
median line from R* onwards almost parallel with termen, a 
dentate whitish subterminal indicated from costa to R', 
3-4 mm. from termen, a conical white blotch from tornus 
obliquely to M*. Hind wing beneath with weak dark cell- 
spot and curved median and postmedian lines and with traces 
of a dentate whitish subterminal. 
Congo, Inkissi (Nkissi) River, Nkalama Falls, 18 April, 
1887 (Jameson), ex coll. Druce, wrongly identified by Druce 
(Jameson’s ‘Story of the Rear Column,’ p. 450) as 
illustrata, Walk. A damaged ¢ from Fantee, Gold Coast, also 
mentioned by Druce, likewise belongs here. The date of the 
type-specimen, correctly given as 18 April on the label, and 
confirmed from Jameson’s itinerary (p. 24), is misquoted 
“18 August” on p. 450. 
Allied to mabillii, but very distinct in the differently 
shaped non-latticed subapical patch, much straighter post- 
median line, lack of white basal dot, ete. 
23. Achea ministra, sp. n. 
3 ¢ .—69-78 mm. 
Near serva, Fabr., with which it has hitherto been 
confounded. Palpus of ¢ with third joint much longer, 
over one-half as long as second. 
Fore wing with the markings and general coloration of 
the darker forms of serva, the blue-purple reflections and 
black-brown terminal clouding almost always strong; fringe 
from near apex to M? pale buff, thus lighter (generally very 
much lighter) than in serva. | 
Hind wing with the interrupted oblique blue-white median 
band narrower than in serva, apical white spot generally 
smaller. 
Underside darker than in serva, the whitish postcellular 
patch of fore wing smaller. 
Dutch New Guinea: Wandammen Mtns., 3000-4000 feet, 
November 1914 (A. HE. & F. Pratt), type and another 
and allotype 9? ; Arfak Mtns. (Pratt); Upper Setekwa 
and near Octakwa River (Meek). Key Islands, Dec. 1915- 
March 1916 (W. J. C. Frost). 
Most of Hampson’s serva ab. | (purpurascens, Strand, 
Arch. Nat. Ixxix. A, (8) p. 73) belong to this species, but 
one or two, including the type-specimen, are dark aberrations 
of serva.
