82 LLOYD'S NATURAL HISTORY. 



Cyaniris were originally intended to include all the Blues, 

 and sometimes all the Lyccenida, or even the Hesperiida as 

 well, 



The European species belonging to this group of Butterflies 

 are always of a blue or brown colour, generally with numerous 

 dark spots beneath, surrounded with paler colour. They are 

 distinguished from the Butterflies allied to Theda by the sub- 

 costal nervure of the fore-wings being four-branched, and from 

 the genera allied to Lycana, by the presence of the upper 

 disco-cellular nervule in the fore-wings. 



GENUS LAMPIDES. 



Lampides, Hiibner, Verz. bek. Schmett. p 70 (1816). 

 Polyommatus^ pt. Latreille, Hist. Nat Crust. Ins. xiv p. 116 

 (1805). 



The comparatively large size, tailed hind-wings, and streaked 

 under side of the only British species of this genus, will pre- 

 vent its being mistaken for any other " Blue." 



The name Lampides has been sufficiently often applied to 

 L. bceticus to warrant this species being regarded as the type. 

 Several recent authors have treated L. bccticus as the type of 

 Polyommatus Latr., but I consider that Latreille indicated 

 P c-vydon as the type of Polyommatus by figuring it ; and more- 

 over the name Polyommatus is wholly inapplicable to L. bceticus.
