NOTES ON THE GENUS LYC^NA. 70 



discoidal spots on hind wings, and the white triangle is more or 

 less distinct. 



Among some Swiss examples of hellargus in my collection is 

 a male from Jura, which is distinctly tinged with mauve. This 

 colour is also noticeable in males from Prussia, and the black 

 spots on the hind margins of inferior wings are rather large. 

 The chequered character of the fringes in one or two examples 

 from the Continent is faint. Most of the females are very typical 

 throughout. The exceptions are examples of ceronus, previously 

 adverted to. 



In English specimens of hellargus the marginal spots, when 

 present at all on the hind wings, vary considerably in size. In 

 some Algerian specimens of the species this character is un- 

 usually well developed. The male of this form, known as 

 punctigera, when held in a certain position appears to have the 

 colour of icarus, and the resemblance to this species is rendered 

 more complete by reason of the nervure-points running into the 

 white fringes in a similar way to that noticed in icarus. Only in 

 jmnctigera the black colour is carried through to the tips of the 

 fringes ; but it does not, however, form patches as in typical 

 hellargus, at least not in my examples. 



Var. iiolona, Z., as adverted to when discussing the named 

 varieties of corydon, has the typical male colour, but is larger 

 than the type, and has the hind margins somewhat broadly 

 bordered with black. The specific identity of this form depends, 

 more esiDCcially perhaps, on the character of its under side 

 ornamentation, which is more like hellargus than corydon. It is 

 found on mountains in Asia Minor. 



In var, cinnus, Hiib., 830-1, the spots on the under side of 

 posterior wings are not ocellated. 



Distribution. — L. corydon occurs in Central and Southern 

 Europe, Western Asia, and North Africa. 



iNIr. Sabine has been good enough to send me, for examination, 

 some of the curious forms of hellargus he took at an inland 

 locality in Kent.* As there may be similar forms in other 

 cabinets it will perhaps be well to give short descriptions of 

 each of these varieties, and also of two others from Folkestone, 

 kindly shown to me by Mr. Sabine.
