 Pyrgus M-alvarum is from a specimen which I took in Italy, near Turin ; Mr. Stephens does not consider it has any claim to he considered an 

 English species, but as it is found in old collections I have thought it right to give a figure of it. The Caterpillars are from Godart, who 

 minutely describes rearing them himself. Cyclopides Sylvius has no greater claim to be considered British than P.? Malvarum, but I have intro- 

 duced it for similar reasons. It is probably a Continental variety of C. Paniscus, and it is not impossible that some English varieties may have 

 been taken nearly resembling it. C. Paniscus is from specimens kindly furnished by Mr. Doubleday, and the Caterpillar is from Godart. H. N. H. 



SPECIES 3.— PYRGUS? MALVARUM. 



Plate x.Kxix. fig. 1 — 5. 



SvNoNVMEs. — Hesperia Malvaniin. Hoffmansegg, Ochsenlieimer. 

 Hesperia Ulah'te, Fabricius, Stewart, Donovan, Ifi, pi. 567. 

 Thymele Malvce, Stcjihens ; Wood, Ind. Ent. t. 53, f. 17. 



Carcharodus Mahce, Hiibner, Tcrz. bek. Schmett. (but not P. 

 Malva; Linn.) 



Papilio AUhecB, HUhner (variety). 

 Hesperia de la Guimauve, Godart. 



The Linna'annaine of Blalvas having been applied to this species, and given as a native insect by Stewart and 

 Donovan, it has become necessary to introduce it into this work to sliow the distinction between the two 

 species ; in fact, the present is more nearly allied to Hesperia Tages ; its dentated wings, however, induced 

 Hiibner to place it in a separate group under the name of Carcharodus. The wings are dentated and brown, with 

 waving cinereous lines, and six transparent spots on the fore wings ; the hind wings beneath dotted with white. 

 Of this species no authentic instance has occurred of the capture in this country. The caterpillar is of a dirty 

 blackish green, when young ; but becomes lighter coloured as it increases in age, with darker longitudinal lines, 

 a black head, and a yellow neck. It feeds on mallows. 



NISONIADES, Hdbner (THANAOS, Boisduval). 



This group differs from the preceding in having longer, slenderer antenncB, with the club attenuated at the 

 tip ; the jialpi with the last joint thicker ; the anterior margin of the fore wings slightly angulated beyond the 

 middle ; tlie surface of the wings not tessellated, and the fringe alternately spotted. It agrees with it in having 

 the wings identical in the outline in both sexes, and in the costa being folded at the base in the males. The 

 wings are deflexed in repose, and they are longer than the abdomen. The difference in their colour in the two 

 sexes indicates a relation with the following group. As tlicre are several species which agree in these respects, 

 I have adopted the group with Iliibner's name, which is prior to that of Boisduval.
