Zoe Mr. R. McLachlan on the 
discovery of the male necessary in order to establish the 
species with certainty. 
Mr. Blackburn once informed me that he had seen (but was 
unable to capture) an Ana that appeared to be larger than 
Junius. 
AGRIONINA.

Varieties. 
1. The antehumeral reddish band narrower than in the type, 
strongly interrupted posteriorly into a point of exclamation, 
not connected posteriorly with the sutural band, and hence 
not furcate ; a small median isolated black spot on the pale 
sides of the thorax. The blackish transverse band on the 
ninth segment broader. 
2. The postocular occipital line totally obliterated, hence the 
top of the head is entirely black. Thoracic lines as in var. 1, 
and there is a large median isolated black spot on the sides of 
the thorax. Ninth segment with nearly its posterior half 
black above. 
A male of each variety taken by Mr. Blackburn with the 
type form (also numbered 28), agreeing entirely therewith 
save in the points mentioned. The obliteration of the post- 
ocular line in var. 2 is important, considering the weight 
given to this character from a classificatory point of view ; 
for my part I incline to the opinion that much undue weight 
is accorded to it, and that it is eminently artificial. 
Agrion (?) hawatvense, n. sp. 
Wings hyaline, rather acute; neuration black. Ptero- 
stigma lozenge-shaped, surmounting slightly more than the 
cellule below it, brownish black, shghtly paler at the edges. 
Quadrilateral having the superior edge about one third the 
length of the inferior in the anterior wings, one half in the 
posterior. Seventeen or eighteen postcubital nervules in the 
anterior wings, fourteen or fifteen in the posterior. Four 
cellules between the quadrilateral and the nodus. 
Dark bronzy green. 
Head black above, with isolated oval orange-yellow post-
