distinctly ringed with wliite, and the club is somewhat more distinct. In I. Helius the joints are much shorter, and scarcely ringed, 

 and tiie club is more gradually formed ; the labial palpi in this species are also narrower than in the preceding named insect. I have 

 added P. Lai-ydas and Pythagoras to the genus on account of their possessing three tails, differing in this respect from the other species 

 of Anthene, which appear to me to be moi'e properly referable to the genus Thecla. The insect figured in Plate LXXIV. under the 

 name of Anops Silas belongs to this group, being nearly allied to lol. Helius.

Genus XI. THECLA. 

 Thecla Fabricius. 



POLYOMMATUS p. God'. 



Body robust : wings (of the male) at least generally more or less coloured with purple or blue ; hind wings with the 



extremity of the subniedian vein not prolonged into a tail. 

 Head short, transverse ; face flattened, scaly ; crown rougher, with scaly hairs. 



Antenncc short, rarely half the length of the fore wings, straiglit ; tlie extremity forming an elongated, more or 

 less thiclvened, and more or less gradually formed club ; the joints preceding tlie club varying in length 

 according to the greater thickness of the club. 

 Labial Palpi short, or but moderately elongated, varying in their direction, being sometimes obliquely porrected, 

 and sometimes with the extremity horizontal ; variable also in their clothing, being often covered with closely 

 adpressed scales, but in other species with the middle joint bristly beneath. Terminal joint slender, and 

 generally short, but in the females of some species (e. g. Th. Phaleros, Marsyas) as long as the second joint, 

 slender, and cylindrical ; in other species (e. g. Th. Betulie, &c.) very shoi-t, and alike in both sexes. 

 Eyes almost always finely hairy. 

 Thorax generally robust, and clothed with soft hairs. 



Fore Wings large, subti-iangular, often marked in the males with a rounded velvet-like patch about the extremity
