94 BRITISH BUTTERFLIES. 



from base of wing as from end of cell. Hind tibiae with two pairs of spurs. 

 Abdomen slender, extending beyond anal angle of hindwings. Male with a linear 

 discal stigma on the forewing in two portions— the upper portion long, lying below 

 the inner margin of cell, from the origin of vein 3 to as far as vein 2 ; the lower 

 portion short, in continuation of the upper portion, from below vein 2 to not quite 

 as far as vein 1. (Antennas and palpi figured, op. cit., pi. iii., fig. 27.) 



There are only two British species in the genus, viz., flava, Briin. 

 (thaumas, Hufn.) and lineola, Ochs. They differ from Thymelicus (as 

 exemplified by acteon) in having a much flatter egg, being very flat above 

 and beneath, the upper surface indeed being slightly hollowed, whilst 

 that of the latter is dome-shaped and much more nearly approaching 

 that of Augiades (sylvanus)., the sculpture, too, is much more definitely 

 marked in Thymelicus than in Adopaea. Too little is known of the 

 larval and pupal stages of the species in these genera to make any 

 comparison, but, in the imaginal stage, considerable differences exist, 

 and the wing-markings of Thymelicus already indicate those of 

 Augiades and Urbicola.

Original description. — P. alis integerrimis divaricatis fulvis con- 

 coloribus, fceminaa immaculatis, maris lineola nigra tenuiore. [Scriba, 

 Journal, iii., p. 244.] I consider this insect, often confused 

 with linea, a distinct species. Size and shape of P. linea, but the 

 forewings rather broader and more obtuse ; the colour paler, and 

 reddish-yellow. The male has, on the forewings. a straight black line, 

 as fine as a hair, and the club of the antenna is black* beneath, whereas 

 it is always rusty-yellow in l\ linea. The underside of the forewings 

 is uniform reddish -yellow, the hindwings (beneath) are paler, almost 

 whitish-yellow, towards the inner margin pale yellow. The above- 

 mentioned characters appear to be sufficient to entitle this butterfly to 

 be considered a good species. As it is found in several parts of 

 Germany along with P. linea at the same season, it cannot be considered 

 an aberrant second brood. Scriba [Journal^ iii., p. 244, Entomolo-
