AMBLYPODIA GEOUP OF THE LYC.EXID.F. 23 



tegumen consists of a very ample and substantial hood, to the lower part of which are 

 affixed, by a strong muscular attachment, the hooks, which are very robust and 

 straightish, with a slight deflection at their tips. The clasps are unusually fully 

 developed, and are excised in the middle so as to form the extremities into two strong 

 points. The penis is short, with the hinder two-thirds very large.

2 . Upperside: both wings very dark purplish brown; primaries with a good-sized 

 patch of violet-blue over the discal submedian and two-fifths of the median areas ; 

 secondaries with the violet-blue only a. little beyond the discal cell. Underside: 

 primaries coffee-brown (more or less dark), with three very short and fine white dashes 

 in the cell ; cell closed by a spot laterally edged very finely with whitish, below which 

 is a longish spot edged above with white; basal area dark up to just beyond the cell, 

 whence the submedian area is quite pale ; transverse band of moderately equal 

 width, strongly curved from the costa to the upper discoidal nervule, from where it 

 descends almost straight to the lower median nervule, below which is an irregular 

 spot shifted inwards; margin rather broadly dark purplish grey. Secondaries: basal 

 area to well beyond the cell very dark reddish brown, whence to the margin it is 

 of an indescribable reddish grey of a lustrous texture, having almost exactly the same 

 appearance as in an insect that is greasy, the separation between the two areas 

 being quite sharply defined ; in the basal area there are traces of a spot across the 

 cell, of one below it, and of a larger one closing the cell, but they are most obscure ; 

 in the lustrous outer area the dark thrice-broken transverse panel is quite distinct from 

 the upper discal to the internal nervure, and is of moderately equal width ; marginal 

 area broadly dark. 



From M. ameria Hewitson this species may be distinguished by its much larger size 

 and by the blue of the secondaries being so much reduced in its txtent, whilst the 

 general appearance beneath is quite different, owing to the uniformity of general 

 tone, though the pattern is very similar ; it is, however, much darker, with the whole 

 of the base dark chestnut, and there is a distinct satiny gloss over the whole of the 

 secondaries. 



I have two females from the Isle of Hainan.
