sides, and from that point a black Stroke is sent downwards upon the cheeks, which 
stroke is margined on its anterior side with tawny red. Palpi black with white rings. 
A small oval black spot upon each side of the throat. Thorax with a dusky or black 
mark each side at its apex and four spots above at the angles of an imaginary square, 
and behind these a faint yellowish brown spot each side of the middle. Feet pale 
dull yellowish. Wings pellucid, their tips angular, those of the upper pair very 
slightly so; an opake pale greenish yellow stigma; veins pale green; veinlets branch¬ 
ing from the rib vein on both sides black at their bases; two series of veinlets towards 
the tip of the wings black, some of them sometimes pale green. Lower wings, veinlets 
on the outside of the rib-vein and bases of those opposite to them black. Wings ex¬ 
pand 1.10. Found the last of June in this State and also in Illinois. Whencaptured 
it emits the disagreeable odor peculiar to several of its kindred species. 
5. (2.) Head above with lolack dots but no stripes. A tawny 
yellow spot on each cheek, commonly with a black line or dot on 
its posterior edge. 
6. (17.) More than two dots upon the top of the head. 
7. (12.) Dots six in number, four at the angles of an imaginary 
square, the anterior two often confluent with the black margin of 
the antennm sockets, and one each side behind the eye. 
8. (11.) A black dot or streak on the posterior edge of the 
tawny spot on the cheeks. 
9. (10.1 Ends of the veinlets black. 
The O-marked Golden-eye (C. Omikron ). This is of a pale green color with a 
light yellow head and a black 0 mark surrounding the base qf each antenna, broader 
on the under side, and above interrupted with orange red between the two anterior dots 
on the top of the head, which are commonly confluent more or less with these black 
rings. This species corresponds with the one last described in all its details, except 
that in addition to wanting the black stripes on the head, the veinlets branching from 
the rib-vein on both sides are black at their tips as well as their bases, and the remain¬ 
ing transverse veinlets are mostly black at their bases; and instead of a line in the 
tawny spot upon the cheeks this commonly has only a black dot. A variety occurs 
in which the tawny reddish spot on the upper side of the basal joint of the antennae 
is wanting. The wings expand from 0.95 to 1.10, the females being slightly larger 
than the other sex. It is a common species during the month of June, and exhales 
the same disagreeable odor as the preceding. 
10. (9.) Ends only of the veinlets on the outer side of the rib 
vein and bases of those given off from its inner side black, all the 
others green. 
The Yellow-headed Golden-eye (C. xantliocephala ) is distinguished from the 
foregoing by having the veins and veinlets all green, except those veinlets which
