it, and on making a preparation of the male armature I 

 was surprised to find the very remarkable ditferences which 

 may be seen on reference to my figures on Plate IX. A 

 careful examination of the genitalia of all the other 

 examples resulted in the sorting out of six specimens of 

 the new form. They were all taken by Mr. Neave in the 

 neighbourhood of the Mansya River and Lake Young at 

 the end of October and beginning of November 1008.

 much like that of a not too fresh example of A. atolmis. Costa 

 very narrowly black. Apex and hind margin narrowly black. 

 Nervule ends black nearly as far as end of cell. A little black 

 at base of wing. Black spots as follows : — One in cell above 

 origin of nervule 2, two on upper part of discocellulars. Beyond 

 these, two together in 5 and 6, one beneath the other, followed by 

 one in 4 more distally placed and pointing outwards. This 

 followed l3y a fourth just beneath it but pointing inwards. A 

 large spot at base of area 2. In lb a minute spot near base 

 close to median, and a submarginal beneath spot in 2 but more 

 distal. 



H.-w. with a little black basal suffusion and a black hind- 

 marginal border about 2 mm. wide with only a faint trace of 

 paler internervular markings. Black spots as on underside. 



Underside. F.-w. as above but paler, and inclined to pinkish 

 Spots as above with an additional brownish mark between the 

 cell spot and end of cell, and another between end of cell and 

 spot in 3. 



H.-w. pinkish red with black spots as follows : — One in 9, one 

 in 8 against precostal, two in 7, the outer one forming the first 

 of a discal band of eight, the second in 6 nearer margin, third 

 in 5, still more distal, fourth in 4, more proximal (immediately 

 under first), fifth in .3 (under fourth), sixth in 2, seventh in Ic 

 more distal, eighth in la, more proximal. Two in cell, the second 

 transverse, and a basal and subbasal in Ic, a s])ot in lb, 

 and a subbasal in la. Marginal border black enclosing small 

 white internervular spots. 



Head black with an orange spot between eyes and two on
