HESPERIDiE.

' vules and radial nervule extremely slender ; internal nervure very long, 
j running not far from inner margin, terminating at anal angle. Legs of 
1 moderate size, first pair smaller than rest ; tibiae of first pair very short, 
without appendage ; tibiae of hind pair usually with two pairs of spurs, 
but in some species (several Palsearctic and three South-African, viz., 
j Willem'i, j^gipan, and Meninx) with the terminal pair only, — no $ tuft 
i in any species ; tarsi stout and rather long, especially first joint, and 
usually more or less finely spinulose beneath. 
I Abdomen long (in $ very slender), and extending as far as or a 
; little beyond anal angle of hind-wings), tufted at tip ; basal half more 
I or less hairy. 
j Larva. — Moderately slender {Morpheus) or stout (Falceinon) ; head 
' smaller than usual in this Family. 
Pupa. — Slender, elongate, very narrowly acuminate posteriorly ; 
■ frontal spine long, straight, projecting horizontally {Morpheus). 
I (These characters of the larvae and pupa of the European species 
" named are from figures by Duponchel and Guenee, and by Boisduval, 
Kambur, and Graslin.) 
j I do not think that Carter ocephalus can be held distinct from 
Cydopides, the only peculiar characters being the slightly lower origin 
: of the lower radial nervule of the fore-wings, and the longer discoid al 
: cell of the hind-wings; for, as Speyer {Stett. Ent. Zeit.^ 1878, p. 181) 
points out, the absence of the second pair of spurs on the hind-tibiae — 
upon which Lederer chiefly relied — is an unstable distinction, occurring 
in Cyd. oriiatus, Brem. This want of the second pair of spurs also 
characterises (as mentioned in my diagnosis above) the South-African 
Willemi, jEgipoM^ and Meiiinx, and these three species are further 
linked by the short first subcostal nervule of the fore-wings running 
into the costal nervure ; but these forms are very unlike in facies and 
pattern of markings. The most aberrant of the known species seems 
to be Zepeletierii, Godt., in which the club of the antennae ends in an 
acute point, the palpi are rather longer, the fore-wings more pointed, 
and the abdomen is thicker ; but in all these features it is approached 
by Tsitct and Inornatus, Trim., which also resemble it in their un- 
spotted plain brown colouring. The South- African conspicuously 
yellow-spotted species are Metis, Or., and Malgacha, Boisd. ; those more 
faintly and sparsely spotted are Willemi, Wallgrn., Syrinx, Trim., and 
the ^ of jEgipan, Trim. ; the little Meninx, Trim., is gaily yellow- 
spotted along the hind-margins on the under-side, and it. Syrinx, and 
Lepeletierii alike have two longitudinal white stripes on the under side 
of the hind-wings. Willemi presents on the under side of the hind- 
wings a very peculiar pattern of black neuration and cross-streaks on 
a pale yellow-ground. 
The prominent distinguishing characters of this genus are the 
absence of any appendage to the fore-tibiae, the not infrequent absence 
of the second or middle pair of spurs on the hind-tibiae, the slender-
