78 THE ENTOMOLOGIST. 



Lyccsna hellargus, Rett. 

 adonis, Hiib. 



The following observations concerning British examples of 

 this species refer to a long series received from Folkestone, 

 the majorit}^ of which were captured and sent to me in 

 September, 1885. 



The male of hellargus, like the same sex of the two species 

 previously considered, is not constant in tint of upper surface. 

 Some few specimens have a decided shade of mauve in their 

 coloration. The fringes of fore wings of all the specimens are 

 chequered with black, but this character is not clearly expressed 

 in hind wing fringes of a few examples. The black spots on the 

 hind margins of inferior wings are fairly distinct as a rule, but in 

 one or two individuals are not even indicated. 



Some of the females received in 1885 are dark brown, with a 

 black discoidal spot on fore wings and deep orange crescents on 

 the hind margins of all the wings of one or two specimens, but on 

 the inferior pairs only of most of the examples. In many cases 

 the crescents are confluent and form a band on the hind wings, 

 but in others, on the contrary, they are very faint. Discoidal 

 spot of primaries, in a few specimens, encircled with whitish-blue. 

 Three examples have a small discoidal spot on hind wings also 

 surrounded with whitish-blue. These last are the only specimens 

 which have distinct discoidal spots on inferior wings. Among 

 many females which have assumed more or less of the male colour 

 are one or two similar to the example figured Plate II., fig. 10, 

 and two others approach the var. ceroiius, Esp., Plate II., fig. 13,* 

 but lack the orange crescents on fore wings. They are, however, 

 similar to examples of ceronus from Magdeburg. 



Under side. — The males are very like the same sex of Icarus, 

 but generally rather darker in colour. The colour and orna- 

 mentation of female seems intermediate between icariis and 

 corydon. Though more closely resembling tlie former, it may 

 usually be distinguished therefrom by its chequered fringes, whilst 

 from the latter it is separated by its more glossy appearance. 



The obsolete, increscent, and confluent phases of aberration 

 are each represented. Nearly all the examples have clear white 



* After Pr. Lang's figure of ceronus, ' Rhopaloeera Europoe,' Plate XXVI., fig. 5. 

 The colours are somewhat brighter thau in the original.
