^. 8-11 mm. (10). Neuration as in Z. lahradus, shape some- 

 wliat similar but apex blunter. 



Upperside dull purplish, with a broad brown outer margin 

 to forewing, widest at apex; a narrower uniform brown outer 

 margin to hindwing. Cilia grey. 



Underside silvery grey, with faint outer marginal bands 

 on outer margins, one jet black spot on outer margin near anal 

 angle (sometimes none, sometimes two). Tilia grey. 



9. 7-11 mm. (10). Neuration and shape as in ^. 



Upperside greyish-brown, with a very variable metallic 

 bluish reflection on centrobasal areas of both wings. Cilia white. 



Underside as in (J, but outer marginal bands better defined. 



This little species may be instantly recognised by the almost 

 total absence of markings on the underside. 



The synonymy of this species is very complicated, almost with- 

 out reason, for both Herrich-SchafFer and Semper distinctly state 

 that the underside is without markings except for the black 

 marginal spot of hindwing. The difficulty Butler and Druce 

 experienced was, that the British Museum contained a single 

 female received from the Godeffroy Museum labelled L. alsulus, 

 which was in reality Z. labradus; but it is impossible to make 

 Herrich-Schaffer's original description agree with any sj^ecimen 

 of Z. labradus I have seen, and many hundreds have passed 

 through my hands. Then again if Z. alsulus^ Z. labradus, 

 Herrich-Schaffer mentioned Z. labradus under two different 

 names, in the same paper, from the same localit}', which an 

 eminent entomologist like Herrich-SchafFer is not likely to have 

 done, for Z. conmiunis is undoubtedl}^ a synonym of Z. labradus. 

 Again, the British Museum specimen was presumably not the 

 type; in fact Herrich-SchafFer may never have seen that speci- 

 men, so it cannot be held to have superior merit to a description
