HEPIALID^E. — HEPIALUS. 5 



fuscous-brown fascia?, the two anterior obsolete! y bifid towards the costa; the 



third fascia on the posterior margin : legs perfect. 

 Var. /3. Male with the anterior wings deep fulvous-brown, with the golden 



fasciae united into distinct strigse, and the costa maculated with paler fulvous. 

 Both sexes vary considerably ; the central golden fascia on tlie anterior wings 



of the male arises frequently from a large patch of gold ; and the posterior 



wings are sometimes speckled with gold on the hinder margin. The female 



has the strigae differing considerably in form. 

 Dr. Leach has distinguished this species in his MSS. by the name Chelomis. 



Not uncommon throughout the metropolitan district in the middle 

 of June, frequenting open places in woods, where it may be observed 

 early in the evening, at a short distance from the ground, performino- 

 its singular vaccillating flight, Mdiich has not inaptly been compared 

 to the motion of a pendulum. I presume that it occurs throuo-hout 

 the country, as I have received it from Devonshire, and Mr. Mar- 

 shall informs me that he took it not uncommonly in Cumberland.

 Stepk. Cafal. A'o. o945. 



Anterior wings more or less luteous or fulvous, with a central longitudinal streak 

 an oblique moniliform striga, reaching from the base nearly to the interior 

 margin, and united at an obtuse angle with another, which terminates at the 

 costal apex, pure snowy white, finely cinctured with fuscous; beyond the 

 outer oblique stria is sometimes a row of fuscous or white spots : posterior 

 wings fuscous, immaculate. Female dusky-ash, with dirty-white moniliform 

 strigae. 



Var. /S. With the anterior wings of the male nearly immaculate dusky-fulvous, 

 and of the female plain dirty-ash. 



Var. y. With the anterior wings slightly spotted with white. 



Var. S. With the anterior wings deep fulvous-brown, spotted with deeper brown, 

 and having the moniliform strigae united with continuous white streaks, with 

 a very distinct series of white spots on the hinder margin. 



Var. £. Anterior wings dirty-white, with the costa, a lunate discoidal spot, and 

 some irregular maculations on the hinder margin, dusky-fulvous. 



Var. f. Anterior wings white, with the costa alone fulvcus-brown. 



No species of Hepialus is more subject to vary than this ; but in all the varieties 

 the cilia are fulvous, and the posterior wings immaculate : both sexes of each 

 variety occur ; and every possible shade of variation may be obtained without 

 much difficulty. 



Caterpillar dusky, spotted with black.
