48 BRITISH MOTHS 



woods of Kent — ^but not common there ; more abundant in the north of England. We are informed by W. F. 



Evans, Esq., that he has reared this species from a caterpillar which fed on geranium, which went into chrysalis 



about Christmas, and the moth appeared early in the spring.

Species 4. — Euthalia elutata ". — (Plate LXVI., Figs. 5, 6, 7, 8.) — Varies from 12 to 15 lines in 

 expanse of the fore wings, which are extremely variable in their tints and markings. They are generally of a 

 dull greenish colour, more or less clouded and streaked with black atoms, with a whitish blotch in the middle 

 of the apical margin ; this spot is sometimes dilated into a whitish striga, abbreviated towards the costa, whilst 

 in others it is obsolete, (thus becoming the species figured by Donovan), and in some the dark strigae become 

 confluent, forming indistinct fasciae ; whilst Ln others, again, the wings are beautifully fasciated, the intervening 

 spaces being paler : the hind wings are brown. The caterpillar is grey, striped with black, with a reddish head 

 and underside of the body. The perfect insect appears in July : it is a common species in woods.

 These insects have the antennae simple in both sexes : the palpi very short and obtuse at the tip ; the body 

 short ; the fore wings somewhat triangular, with the tips acute and the disc with oblique strigse : the hind 

 wings small ; the hind tibiae are not dilated. The caterpillars are smooth and linear, with pale stripes and ten feet. 



Species 1. — Phibalapteryx tersata ". — (Plate LXVI., Fig. 9.) — Measures about Ij- inch in expanse 

 of the fore wings, which are of an ashy-brown colour, with numerous slender, oblique, dark, equidistant strigae 

 running across all the vrings, and being most evident on the hind pair ; the fore ones with a small black discoidal 

 dot, and all the wings vrith a slender, undulated, whitish submarginal line. The caterpillar is brown, with a 

 pale dorsal line varied with white, and with the sides varied with gray, brown, and black : it feeds on Clematis 

 vitalba, and the moth appears in June in woods and hedges, and is a rather common species.

Species 2. — Phibalapteryx vitalbata^* . — (Plate LXVI., Fig. 10.) — Measures from 1 to Ij- inch in expanse 

 of the fore wings, which are fulvous or greyish-buff, marked with numerous slender, dark, and light strigae ; the 

 costa, and a broad oblique brovsTi striga, running from the apex nearly to the base of the inner margin : the hind 

 wings also with a central fascia of brown, formed of confluent strigae. Taken in woods and hedges, where 

 Clematis vitalba occurs, but not very common.

Species 3. — Phibalapteryx lignata *. — (Plate LXVI., Fig. 11.) — Measures about 1 inch in expanse of 



the fore wings, which are of a greyish-buff or pale ochreous, with many darker strigae, and two oblique brown 



fasciae, the anterior of which is ashy towards the costa, and marked with a black dot ; and the outer one extends 



from the apex to the inner margin, being darkest behind : the antennae of the males are strongly ciliated. 



This species seems to prefer marshy places, being taken in Battersea-fields, Cambridge, &c., but not common, 



at the middle of August.
