The British Butterflies Described 



having a semicircular row of light spots near the tip of 

 the fore-wing. These are very faintly visible in some 

 males, but they have, in addition, a black streak along 

 the centre of the wing. The under side in both sexes 

 is similar, a pale dingy fawn, with no particular mark- 

 ings. The antennae are very short. 



The caterpillar is green, with a dark line on the back, 

 and a double line of yellow on each side. This species 

 may be looked for on rough ground facing the sea 

 during July and August. 



THE LARGE SKIPPER (Hesperia Sylvanus), Plate 

 XIII., Fig. ii. Upper surface tawny-orange shading 

 into darker at the margin of both wings ; on this dark 

 margin are a few pale spots, mostly at the tip of the 

 fore-wing. The male has an almost black streak near 

 the centre of the fore-wing ; this is not present in the 

 female. The under side is a light tawny olive, with 

 pale lighter spots. 



The caterpillar is green, with a dark line on the back, 

 and a light stripe on the sides. It is a grass-feeder. 

 This Skipper is abundant all over England in May and 

 again in August, but is rare in Scotland.

 Fig. 12. This species is not quite so large as the last. 

 It is darker, and the spot markings are much brighter 

 and more decided. This is the case especially on the 

 under side, as there the spots are bright enough to 

 suggest pearls. Hence the name. 



Note, too, the dark streak in the middle of the fore- 

 wing of the male ; it is divided along the centre by a
