86 THE ENTOMOLOGIST. 
P. comptana, Frol.—Abundant on all chalk downs. There 
are two broods in the year, the first appearing in April and 
May, and the second in August and September. From its 
small size and short jerky flight it requires a good eye to detect 
it, and it is not easy to capture. ‘The larva is said to feed 
between the leaves of Potentilla. 
P. myrtilana, Treit.—Local and not common in these coun- 
ties. ‘he imago appears in June; the males may be taken towards 
sunset flying over bilbery (Vacciniwm myrtillus) ; the females at 
rest on the same plant. It occurs near Haslemere; on the White 
Hills, near Caterham; and at Sevenoaks. 
P. lundana, Fab.—Common and widely distributed throughout. 
It is double-brooded, occurring in May and again in August, 
and is a free flier, The larva feeds between united leaves of 
the bush vetch (Vicia sepium), and the meadow vetchling (Lathyrus 
pratensis). 
P. derasana, Hub.—Loeal, but not uncommon where it occurs. 
The imago appears in June and July, and occurs in the lanes 
round Croham-Hurst, Surrey; at Haslemere, Tilgate Forest; 
and the lane leading to Darenth Wood, where it is sometimes 
abundant. Mr. C. G. Barrett writes, ‘It has been reared by 
Mr. Machin from larve feeding on Rhamnus frangula. 
P. diminutana, Haw.—A local and uncommon species. The 
imago appears in June and July, and, Wilkinson says, among 
sallows; but I have on more than one occasion beaten a single 
specimen from wild cherry. It occurs at Croydon, Box Hill, and 
West Wickham; Darenth Wood, near Strood, and Folkestone; 
Haslemere, Tilgate Forest, and Hastings. 
P. Mitterbacheriana, Schiff—Common in all oak woods. The 
imago appears in May and June, and may be taken in abundance 
at dusk flying round the oaks. It is strong on the wing and flies 
high. The larva feeds on the oak. 
P. upupana, Treit.—Rare, but widely distributed. The imago 
appears towards the end of May, and in June among oaks, and 
should be looked for at dusk flying around those trees. It has 
occurred at West Wickham several times; also at Darenth 
Wood, near Strood, Tunbridge Wells ; and near Hastings. The 
larva feeds on the oak. 
P. lactana, Fab. = harpana, Hub. = ramella, Linn. — An 
uncommon species, but distributed. The imago appears in May
