AGRION 259

Syn: Calopteryz 
Black Wings 
These are elegant bronzy green damselflies with broad wings, vari- 
ously cross banded with brown. The bodies are wholly metallic green; 
the legs are long and black and spiny. There is no color pattern except 
on the wings. The stigma is wanting in the male and very irregular in 
the female, being traversed by irregular cross veins. The wings have 
abundant venation with many short intercalated sectors between the 
principal veins towards the wing margin. The quadrangle is long and 
narrow and traversed by many cross veins. The two branches of the 
median vein are fused with R, after their departure from the arculus.

The flight of these damselflies is slow and wavering, butterfly-like, 
fluttering from one resting place to another, by the waterside. The 
female oviposits unattended. 
The nymphs (Ndm. ’03, p. 224) cling to roots and stems swaying in 
the current. They are long legged, stiff, awkward creatures that move 
but little from place to place. Two of our species have been reared: A. 
maculata, which has the basal segment of the antennae as long as the 
head is wide; and A. aequabile, which has it a third longer. Another, A.
