CATOCHRYSOPS. 411 



joint about half length of second; eyes in the typical form hairy; 

 body robust. 



Of the three forms of Catochrysops that occur within our limits two 

 have the eyes smooth ; the venation however, is slightly variable 

 and the forms with smooth eyes have veins 11 and 12 of the fore 

 wing very close to each other but not touching.

d . Upperside : pale violet with in certain lights a blue, slightly 

 silvery sheen. Fore wing .- a slender anticiliary dark line. Hind 

 wing : interspace 1 with a short transverse subterminal brown 

 bar edged inwardly with white ; interspace 2 with a prominent 

 round black spot edged very faintly on the inner side by a diffuse 

 bluish lunule ; the dark subterminal spots of the underside apparent 

 through transparency ; an anticiliary slender jet-black line m ore con- 

 spicuous than in the fore wing, in some specimens edged inwardly 

 in the posterior interspaces with white ; this line is present in inter- 

 spaces 1 and 2 in all specimens. Cilia of both fore and hind wings 

 white transversely traversed medially by a brown line ; tail black 

 tipped with white. Underside : pale dull grey. Fore wing : a 

 short transverse band on the discocellulars, a small round subcostal 

 spot in interspace 10, a transverse discal band that extends from 

 veins 1 to 7, the portion below vein. 3 dislocated and shifted 

 inwards, a transverse subterminal ill-defined band and a terminal 

 series of inwardly rounded spots, each of which subapically fills an 

 interspace, dark greyish-brown ; the discocellular and discal bands 

 edged inwardly and outwardly by white lines, the subcostal spot 

 encircled with white and the subterminal band and terminal spots 

 edged on their inner sides with the same colour ; lastly, a dark 

 greyish-brown anticiliary line. Hind wing : a subbasal spot and a 

 spot beyond it in interspace 7, a large round subterminal spot 

 crowned with ochraceous in interspace 2, two geminate specks 

 subterminally in interspace 1 and a terminal similar speck in 

 interspace 1 a, black, the spots in interspace 7 encircled with white ; 

 a lunular spot in middle of cell, two elongate spots in transverse 

 order below it, a short transverse band on the discocellulars and a
