3o6 LEPIDOPTERA. 



Female very similar, a little stouter, and having threadlike 

 antennas. 



Undersides of all the wings whitish-brown ; the fore 

 wings tinged, on the costal half, with red-brown ; discal and 

 central ringed spots just indicated, and the outer dotted 

 lines more distinctly so. Body and legs pale brown ; tarsi 

 red-brown. 



Not very variable, but the central line or stripe is often 

 obscure, or. on the other hand, sometimes strongly empha- 

 sized, and clouded with purple-brown on its margins ; the 

 ordinary first and second lines are equally, or more, incon- 

 stant. In the second brood there are often small purple 

 clouds in a row near the hind margin, iudicatiug a sub- 

 terminal line. Occasional specimens have the fore wings so 

 much suffused with dull red as to obscure the markings. In 

 the collection of Mr. Sydney Webb is one of an almost 

 unicolorous piali ; and another in which the Jirst line is 

 very distinct and sharply defined, also strongly angulated. 

 In that of Mr. F. C. Woodforde is a strongly dusted female 

 having a broad cloud of brilliant red upon each fore wing. 



On the wing at the end of May and in June ; also as a 

 very partial second generation in August and September ; in 

 the year 1862 I captured it in October, but such a circum- 

 stance is rare. 



Larva. Head slightly broader than the second segment ; 

 body slender, cylindrical and rather rugose, the roughness 

 arising from transverse division of the segments into narrow 

 sections, which emit small bristles ; fawn-colour, wdth the 

 head of the same colour, and delicately reticulated with 

 umber-broAvn ; on the dorsal area of the body are five or 

 seven dotted white rivulet lines, very inconspicuous except 

 under a good lens ; on each segment are four dark brown 

 dots forming a square, and on the side of each segment, 

 particularly observable from the fifth to the tenth, is an 

 oblicpie dark mark, broad at the anterior extremity, but
