EURYBIA. 375 
presence or absence of an ocellus at the end of the cell of the primaries. A blue 
sheen over the wings serves as a basis for another division. 
The subcostal nervure of the primaries of Eurybia halimede emits two branches 
before the end of the cell and two beyond it ; the lower and middle discocellulars are 
atrophied only towards their junction with the lower radial; the upper radial and the 
middle discocellular meet the subcostal at the same point, the latter at a small acute 
angle; the lower discocellular meets the median nervure some way beyond the origin 
of the second branch also at an acute angle; the costal and median sides of the cell 
are subequal. The secondaries have a strong basal nervure ; the upper discocellular 
is not atrophied, it leaves the subcostal a little before the first branch, and runs in an 
almost continued curve with the radial; the lower discocellular is atrophied towards 
its junction with the radial and meets the median some way beyond the origin of the 
second branch, the median itself being somewhat abruptly bent at the point of junction ; 
the costal side of the cell is much shorter than the median side. 
The front legs of the male have a slender coxa; the femur is short, somewhat 
dilated towards its distal end; the tibia > femur, also dilated towards its distal end; the 
tarsus is single-jointed, nearly=2 tibia, is much swollen and club-shaped for about 
two thirds of its length. The terminal joint of the tarsus of the front leg of the female 
is longer than either of the three preceding joints; the first, second, third, and fourth 
joints all terminate with two strong spines. The palpi have a very small, nearly 
spherical terminal joint; the middle joint is at least eight times as long as the first ; 
basal joint dilated, =4 middle joint. ‘The antenne have forty-three joints, and taper 
very gradually towards a small elongated club. 
The tegumen has a double lobe, setose on the outer surface towards the extremity, 
and with two strong lateral hooks. The harpagones have two long strong spines 
which diverge from one another outwardly; the upper spine is setose on its under 
surface towards the base; the under spine has a pencil of longer hairs about the middle 
of its length. The penis is strong and pointed, and a strap curved outwardly connects 
its base with the base of the harpagones.
