108 BRITISH MOTHS 



These insects, moreover, in all their states, present further characters remarkably aberrant from the great 

 majority of the family. The head is fm'nished with an elongated spiral tongue ; the labial palpi are slender ; 

 the caterpillars naked, and gradually becoming more slender towards the tail (hence named by Reaumur 

 " chenilles en forme de poisson ") ; the cocoon is in the shape of a boat reversed, attached to a leaf ; and the 

 clirysalis is not furnished with the transverse rows of reflexed spines on the abdominal rings, whereby, in the 

 majority, the insects in this state are able to protrude themselves from their cocoons. 



Species 1. — Hylophila prasinana ^ — (Plate LXXIX., Figs. 1, 2, 3) — Measures from li to 1| inch in 

 expanse ; fore wings pea-green, with three oblique silvery bars ; the first occasionally nearly obsolete, and the 

 third rather curved, and extending to the apical angle of the wings ; the male has the hind wings pale greenish- 

 buff. The caterpillar is pale green, with black dots, and with a pale yellow line above the feet on each side. It 

 feeds on the oak, ash, and other trees ; and the moth appears in May and June, and is very common in woods.

Species 2. — Hylophila quercana ^ — (Plate LXXIX., Figs. 4, 5, 6) — Measures from If to 2 inches in 



expanse ; fore wings grass-green, with two slender oblique white or pale-yellowish strigse ; hind wings glossy 



white. The caterpillar is pale-green, with a slender yellow line on each side of the abdominal segments. It 



feeds on the oak and alder ; and the moth appears in June and July, in woods, but is much rarer than the 



preceding species.

EARIS, HiJBNER, Stephens. HALIAS, pars, Curtis. 

 The type of this genus is very nearly allied to the two last described insects, especially in its preparatory 

 states ; but has the palpi shorter and stouter, with the middle joint more squamose ; the antenna slightly 

 pubescent beneath, in the males ; the fore wings not traversed by pale oblique strigK. The caterpillar 

 attenuated at each extremity ; feeding, according to Duponchel, amongst the leaves at the extremity of the 

 twigs of sallows, which it unites with threads. 



Species 1. — Earis chlorana " — (Plate LXXIX., Figs. 7, 8, 9) — Measures rather more than | inch in 

 expanse ; fore wings pea-green, with a white costa ; hind wings shining white. The caterpLUar is obscure 

 green, with a pale line on each side and the belly reddish-brown. It feeds on sallows and willows ; and the 

 moth appears in June and July, and frequents willow beds, but is not common.

TORTRIX, LiNN^us. 

 These insects have the antennae pubescent beneath, in the males ; the labial palpi porrected, compressed, and 

 very broad in the middle ; the spiral tongue shorter than the palpi ; the head thickly tufted ; the wings, when 

 closed, forming an ovate triangle ; the fore ones destitute of strigse or borders. The caterpillars are 16-footed • 

 they reside within a convoluted leaf; and the chrysalis has the abdominal segments serrated.
