Species 2. — Venilia 4-macularia ' — (Plate LXXII., Fig. 3) — Measures 13 lines in expanse ; wings 

 ochreous-yellow ; anterior ones with the costa freckled with dark scales at the base, and with three or four purplish- 

 brown spots. Taken in April and May, in some of the woods in Middlesex, to the north of London, but very 

 rare. It has been supposed to be a variety of the preceding, but it appears too constant in its markings, many 

 specimens of it having occurred.

The antennae are slender and ciliated beneath in the males ; the palpi small, but porrected horizontally, with 



the extremity ovate-conic ; the spiral tongue long ; the wings round and shortish, with tlie margins entire ; tlie 



disc generally obscurely coloured, with a dark central dot ; when at rest they are extended horizontally ; the 



hind tibise are dilated in the males, and furnished with a long brush of hair ; they are destitute of spurs, and 



those of the females have only one pair at the tips in some of the species, but two pairs in others ; and the hind 



tarsi are in some species very short. From the structure of the feet Mr. Stephens divides the genus into two 



sections. 



A. Hind tibia of the females with one pair of spurs at the tips.
