AMBLYPODIA GEOTJP OF THE LTC^NID^. 65 



larger spots across the central discal area ; cell closed by a subquadrate spot, below 

 which is a smaller one connecting it with the third central discal spot ; chain-like 

 band composed of eight spots, the two distinct upper spots outwardly inclined, third 

 and fourth spots confluent, shifted well outwards, fifth spot small, shifted inwards, sixth 

 spot outwards, the angular seventh confluent with the long eighth spot which touches 

 the internal nervure ; submarginal row distinct, extending very narrowly over the 

 metallic spots up to the internal nervure, the light edging of which is more pronounced 

 in the anal area ; the black spots at the anal angle are almost entirely covered with 

 metallic bluish-green scales up to the second median nervule ; tail brown, tipped with 

 white ; submedian nervure very slightly prolonged, so as to form a very short tooth-like 

 anal projection ; extreme margin pale. 



$ . Upperside : primaries rich purplish black, with a patch of purplish blue 

 occupying the cell, the submedian area, and about half of the posterior area below the 

 upper median nervule. Secondaries dark brown, with a small patch of purplish blue 

 occupying about the discoidal area ; tail darker, tipped with whitish ; fringes grey. 

 Underside as in male. 



I have described the blue of the male as iridescent ; this is not absolutely correct, 

 but is the best term I can use, the one wing in the light looking very much brighter 

 than the other, and in one particular light the wing looks lustrous brownish. 



It is evidently a common insect in Celebes, judging from the number Mr. Doherty 

 sent over here. 



This is a very distinct species and should be recognised at a glance on account of the 

 peculiar blue of the male and its exceedingly broad outer margins, while on the underside 

 of the primaries the upper four spots of the transverse band are peculiar, the first spot 

 quite small, second rather larger, third and fourth very much larger ; the whole of the 

 underside is also very distinctly marked. The genitalia have the usual hooded tegumen 

 and straightish hooks, the clasps are ham-shaped with squarish extremities. The 

 penis is rather small for the size of the insect and is straight.

Expanse, d 49, $ 44 mm. 



From dohertyi this species may be recognised by the brighter blue, very much 

 narrower borders, much shorter tail, which is little more than a tooth-like projection, 

 whilst below in the primaries the transverse band is not dislocated, but in the 

 secondaries it is strongly dislocated. It is much nearer arzenius Felder, but is very 

 much larger than that species ; the distinctions are given in the description of that 

 insect.
