The best place is to tbe east of Luiworth Cove, on cliffs facing the sea. A 

 little further on is a minature undercliff. On this undercliff grows a mass 

 of Inula critkmoides, below is the clear blue water af Weymouth Bay. In 

 that little space, almost without moving, I have captured, or at least seen, 

 no less than twenty-three of our British butterflies, viz. : Pieris brassictz, 

 rapa, and napi ; Colias edusa, with its var. helice ; Melanargia galathea, 

 Satyrus semele, tithonus, janira, megtzra, and pamphilus; Chrysophanus 

 phlceas ; Lyccena corydon, adonis, alexis, agestis, and agon, and Nisoniades 

 tages. 



Genus XXIII.— SYRICTHUS. 

 Boisduval. 



This genus which is called Thymele by Stainton and Hesperia by Kirby 

 contains over sixty species, all of which are black, chequered with white spots. 

 About fifteen of them are European, but only one British. In the folded 

 structure of the costal margin of the fore-wings of the male, Syrictkus is 

 closely allied to Niso?iiades, from which, however, they are distinguished by 

 their strongly tesselated wings. The obtuse tip of the antennae, destitute of 

 a hook, separate them from the other genera. 



SYRICTHUS ALYEOLUS. 

 Spotted Skipper. 



Alveolus, Hub. Alve'olus, a chess board, given in reference to the 

 black and white appearance of the butterfly, which is chequered with some- 

 what square spots. 



It is also called Malva, but the true Malvce of Linnaeus is apparently 

 another species, according to the Yienna Catalogue, Alcea, the caterpillar of 

 which feeds on. Malva. 



This pretty little species measures from an inch to an inch and two lines 

 in the expansion of its wings. On the upperside they are of a blackish 

 brown, chequered with somewhat square white spots, and with chequered 

 fringes. On the underside they are somewhat similar, the ground colour 

 being greyish brown. A well known variety having the spots confluent was 

 figured as long ago as 1717, by James Petiver, in his "Papilionum Britan- 

 nicas Icones," under the name of the Brown Marsh Pritillary. Lewin also 

 gives three excellent figures of it in 1795, and calls it Fritillum, Fabricius. 

 He records it as being but seldom met with in England, and that our know-
