6 BRITISH MOTHS 



ANISOPTERYX, Stephens, Boisduval. HYBERNIA, p. Coetis. 

 The fore wings in the males of this genus are long, entire, and of a very delicate structure ; the antennas of 

 the males very slender and finely bipectinated ; the palpi short ; the spiral tongue scarcely distinct ; the thorax 

 weak and villose ; the abdomen slender ; the female with very short rudiments of wings ; the larva smooth, 

 slightly elongated, and twelve-footed ; it feeds on the leaves of trees. 



Species 1. — Anisoptbrtx iEscinARiA''. — (Plate LVII,, Figs. 18, 19.) — This species measures from H to 

 1|- inch in the expanse of the fore wings of the males, which are of a pale glossy ashy-brown colour, with a 

 central, broad, slightly dusky fascia, outwardly edged with a white dentated line, and an oblique brown line, 

 which extends to the tip of the wing from the outer angle of the preceding striga ; the hind wings with a dusky 

 central dot and an indistinct fascia ; the caterpillar is green, with pale longitudinal lines ; it feeds on the horse- 

 chestnut and other trees, and the imago appears in March.

HYBERNIA Latreille, (LAMPETIA, Stephens, glim.) 

 These insects have the sexes also very dissimilar, the females being entirely or nearly destitute of wings ; the 

 palpi very minute and the spiral tongue almost obsolete, being formed of two short lanceolate lobes, to which are 

 attached a pair of minute 3-jointed maxUlary palpi ; the antennae are slender and bipectinated in the males ; the 

 wings in the males are large but weak. The caterpillars are smooth, slender, elongated, and ten-footed ; they 

 feed on the leaves of trees and the perfect insects appear in the winter and spring. 



Species 1. — Htbernia leucophearia '. — (Plate LVII., Figs. 16, 17.) — The males of this species vary from 

 1^ to If- inch in the expanse of the fore wings, which are variable in their colour, being of a pale ashy tint, more 

 or less saturated, und clouded with dark scales ; an incurved slender fascia before, and another deeply waved 

 beyond the middle, followed by a dark cloud-like fascia, considerably mottled. The hind wings mottled, and 

 with dusky clouds near the anal angle. Our English Entomologists appear to have regarded as the female of 

 this species, that of H. capreolaria (our figure 21) and vice versa. The observations of Captain Chawner and 

 Mr. H. Doubleday have, however, satisfactorily proved the incorrectness of this supposition ; the true female of 

 Leucophearia being entirely wingless. A common species, which flies in woods round London and other parts of 

 the country, in February and March, preferring places where oaks abound, and flitting about with an undulating 

 motion by day, between the hours of eleven and two, p.m., and rarely ascending higher than the tops of the 

 underwood.

thickly irrorated with dark atoms, and with a nearly straight, slender, dark striga before the middle of the wing, 



and another much bent towards the costa beyond the middle, beyond which is a broad darker bar, with a row of
