** Bopy, small, slender, and compressed. WINGS, generally large, and of a delicate tex- 
ture ; in the majority of the species blue on the upperside (at least in the males) and grey or 
greyish-white beneath, and more or less ocellated, [as restricted by me all the species are ocel- 
lated] ; the majority having a small black transverse spot at the extremity of the discoidal cell of 
the forewing [all the Indian species have this spot on the underside]. HEAD, small, hairy, the 
hairs often forming a small tuft on the forehead ; eyes moderate-sized, naked ; Za/pi moderate- 
ly elongated, compressed, scaly ; the middle joint also furnished beneath with detached bristly 
hairs; terminal joint shorter than half the length of the second joint, and scarcely varying in 
length in the opposite sexes, slender, nearly naked, acute at the tip ; aztenn@ of moderate 
length, very slender, with long joints ringed with white, the club distinct, suddenly-formed, 
oblong-ovate, depressed, and sometimes spoon-shaped in dried specimens, the joints of the club 
very short. FOREWING, generally elongate, subtriangularly ovate, with the costal margin moder- 
ately arched, outer margin always more or less convex, z#ner margin rather short ; costal nervure 
short, szdcostal nervure wide apart from the costa, with two branches preceding the extremity of 
the discoidal cell, and with a third short branch about [less than] half-way between the cell and 
the tip of the wing ; discoidaé cell closed by extremely slender middle and Jower disco-cellular 
nervules, which are transverse, the latter uniting with the third median nervule at a 
moderate distance beyond its origin; wpper- disco-cellulary nervule very oblique, or almost 
longitudinal, forming, in fact, the base of the upper discoidal nervule.” H1INDWING, 
elongate-ovate, entire; costal margin straight, afex rounded, outer margin very convex, 
anal angle rounded, abdominal margin nearly straight ; costal nervure extending to apex of 
wing, first subcostal nervule given off some distance before apex of discoidal cell, disco-cellular 
nervules very concave, of about equal length, the «fer disco-cellular outwardly, and the 
inner disco-cellular inwardly oblique ; @éscotdal nervule from their point of junction, discoidal cell 
very short, much less than half the length of the wing, second median nervule originating just 
before the end of the cell. ‘‘ FORELEGS, of the ma/e slender, tidia in most species terminated 
by a short curved horny point ; in others simple ; ¢arsus slender, exarticulate, elongate, slightly 
curved and attenuated at the tip, which is terminated by a horny curved point, and armed 
beneath with short spines. Of the female similar in size and shape to those of the male, except 
that the ¢arsus is articulated and unguiculated like those of the four hindlegs. H1INDLEGs, 
short, slender.” 
““LarVA, onisciform, gibbo-scutate or oblongo-scutate, with the head and feet small and 
scarcely perceptible ; the body laciniate, and the back convex and generally beautifully colour- 
ed. Pupa, oblong, very convex, smooth, obtuse at each end, and marked with obscure spots ; 
in a few species armed with short acute tubercles.” (Westwood, 1. c.) 
The above diagnosis of the genus Zycena follows generally that given by Westwood in 
the ‘* Genera,” but it has been modified somewhat so as to suit the genus as now restricted in 
this work, and so as to exclude species which are now referred to several separate genera estab- 
lished in late years. 
With reference to the synonymy of this genus, it will be noted that the Plebez? of Linnzeus 
is the oldest name used for it. Mr. Kirby in the later portion of his ‘* Synonymic Catalogue 
of Diurnal Lepidoptera” gives the singular form to the word and uses it for the genus. As
