CHRYSOCLISTA. 241 — 
the terminal joint thinner, acute. Tongue of moderate length, clothed 
with scales. Wings with very long cilia, the anterior elongate, adorned 
with metallic tufts, the posterior lanceolate, with a distinct anal angle. 
Tn the anterior wings the discoidal cell is posteriorly dilated, imper- 
fectly closed; the secondary cell is indicated; the apical vein is fur- 
cate, and below it are four veins; the subdorsal has a narrow fork at 
the base, and at its apex has rather a tendency to become fureate; the 
submedian is not thickened; in the posterior wings the median vein is 
trifid, the discoidal vein sends two branches to the hinder margin, the 
apical vein is simple. 
The species of this genus do not exhibit an entire accordance : 
in Linneella the apex of the subdorsal vein of the anterior wings 
is quite simple; Schrankella has no anal angle to the posterior 
wings, and in this, as also in flavicaput, the apical vein of the 
posterior wings is connected with the discoidal. Mavicaput is 
besides destitute of the metallic tufts of the anterior wings. 
The perfect insect of Linneella is rarely seen on the wing, 
generally resting on the trunks of lime-trees; flavicaput flies 
freely in the afternoon along hawthorn hedges. The larva of 
Linneella feeds on the inner bark of the lime during the winter 
and spring (as observed by Mr. Boyd and Mr. Wing last year) ; 
it has the third and fourth segments somewhat enlarged. The 
larva of Schrankella, discovered by Mr. Scott, mines the leaves of 
the Lpilobium alsinefolium in May. 
The species may be tabulated as follows :— 
a, Anterior wings orange and black. 
4. Posterior wings with distinct anal angle. Species 1, 2. 
6 6, Posterior wings with no anal angle. Species 3. 
aa, Anterior wings entirely black. Species 4.

Mead and face shining black. Palpi whitish, the terminal joint 
black. Antenne black, with white tips. Anterior wings deep orange, 
with the base, costa, and inner margin narrowly black, and the apex 
broadly black, thus leaving a longish elliptic patch of the ground- 
colour, into which a short black dash runs from the base above the 
fold; along the costa and at the apex are numerous silvery scales ; 
there are three round tufts of black and silvery scales, the first near 
the inner margin before the middle, the second near the costa in the 
middle, the third in the fold towards the anal angle; cilia blackish.
