Genus Psalis (pi. V, fig. 9). 
Psalis, Hiibn., Ziitr., 2, p. 19 (1827) ; non-descr. 
Moore, Lep. Ceyl., II, p. 94 (1882) ; type securis. 
Hmpsn., Ann. S.A. Mus., p. 393 (1905). 
Proboscis absent ; palpi just beyond frons, about of length of eye, 
slightly drooping, and thickly covered with long hair; first joint very 
small ; second joint very large and thick towards end, somewhat pear- 
shaped and bent at beginning ; third joint absent ; eye elliptical, about 
f of frons ; ante rinse of $ very much curved, bipectinate ; longest branches 
about 8 to 10 times thickness of shaft, ending in 2 long bristles and on 
inner side also curved, especially towards apex ; basal joint of shaft thick ; 
in $ the antennae are a little shorter, slightly pectinated, and pecten getting 
gradually shorter and ending in 2 short bristles ; vertex covered with 
woolly hair ; frons with a well developed pointed tuft ; thbrax covered 
with long woolly hair ; abdomen a little longer than hind wing, in $ often 
with more or less developed woolly crests ; fore tibia with a long pointed 
outwardly curved process (even longer than in any Lcelia ) ; femora, tibiae, 
processes, and tarsae with long spreading hairs ; in the $ the process is 
absent, but the hairs are much longer ; mid and hind legs with long spread- 
ing hairs ; mid tibia with 2 spurs ; hind tibia with 4 spurs. 
Fore wing in $ sub -triangular ; costa very much arched ; termen 
very oblique, straight ; inner margin somewhat rounded ; apex well 
rounded ; tornus rounded (in $ the wing is more elongate ; costa more 
arched, especially towards apex ; termen very oblique and hollowed out 
near apex ; inner margin as in ; apex very much produced ; tornus 
well rounded) ; vein 16 simple at base ; 2 from § of lower median ; 3 from 
J of lower median ; 4 from angle ; 5 from just above the angle ; disco- 
cellular present and angled inwards ; cell about \ of wing ; 6 from just 
below upper angle ; 7 stalked with 8 for \ of vein 7, stalk from upper 
angle ; 9 stalked with 10 for § of 9 and from -J- upper median ; 9 approach- 
ing 8 a little beyond the stalk and anastomosing for \ the free length of 8, 
so as to form a rather long areole ; 11 from § upper median ; 12 nearly 
parallel to costa. 
Hind wing triangular ; costa slightly hollowed out at middle ; termen 
a little lobate at vein 2-5 ; inner margin evenly rounded ; apex and tornus 
well rounded ; la long and straight ; 16 at middle of la and 2 ; 2 from 
f of lower median ; 3 and 4 on a short stalk or from a point at lower 
angle, or sometimes a little apart ; 5 from well above the angle ; disco- 
cellular faintly represented, oblique, and angled at about. § ; cell over J of 
wing ; 6 and 7 on a stalk of \ and from upper angle ; 8 bent towards 
upper median at J and slightly touching it. 
I think that this genus has developed from Dasychira almost parallel 
to Lcelia, from which it differs in its two-jointed palpi. This character 
also separates Psalis from Dasychira, and I therefore do not see how this 
genus can be taken as a sub-genus of Dasychira. It is true that the 
neuration is very much alike in the three genera, but the process of the 
fore tibia and the missing third joint of the palpi is, I think, sufficient to 
keep it separate. There is less difference between Dasychira and Lcelia 
than there is between Dasychira and Psalis.
