ocrisia; it is roughly circular and might almost be described 
as like a greenish rose with the brand forming the stamens, 
&c.; all the surrounding bluish green wing scales are set up 
around it forming a raised ridge, the scales themselves looking 
just like the petals of a flower, the androconia being sunk in 
the middle (as are the stamens); moreover, to add to the 
simile, they are yellowish scales overlaid with chestnut red; 
they are not however erect, the androconia are narrow, 
longish, with somewhat truncated apices. The general 
scales over the wing in this species are excessively small and 
finely serrate, and are totally different in size and shape from 
the largish petal-like surrounding pattern and from the brand 
itself. 
In Thecla polybetes, a very brilliant blue species, we find a 
brand with an extension, and that ina different place from the 
usualone. Any addition to the sex mark is usually in the costal 
area, but in polybetes it is in the lower radial area, extending 
from the definite brand itself (which is easily discerned) a 
third along vein 4, and reaching straight down to vein 2; 
the ordinary scales on the basal side are set up to the andro- 
conial patch, much as in the previous species, but are not so 
on the costal margin; the patch itself is large, consisting of 
closely packed nearly erect scales, pyriform in shape, with 
the thick end at the base and the apex gently curved; in 
colour they are dark brown, but there is a small patch of pale 
brown ones of a broader pattern and equal width; those 
covering the extension are different, being very broad and 
short, the breadth almost equalling the length, and they are 
not erect, but are set at nearly the same plane as the blue 
scales, only they have a much greater overlap. The brilliant 
blue scales in this insect are set at a higher angle than usual, 
being by no means so flat, and they are curved, as is not in- 
frequently the case with the very metallic blue and green 
colours. In Thecla phaleros, another metallic blue species, 
the brand is set in a deep pit, the sides of which are set with 
the ordinary brilliant blue scales (set petal-ways); from the 
base of the pit it rises up like a minute crater, up whose sides 
very large broad scales of a pale brownish colour rise, and 
they appear to be of an unusual length, though it is extremely
