Odonata from Ecuador. 31 
dorsal median black line dilated at each end, and 
enclosing posteriorly two pale spots; an ante-humeral 
black line indicated by a large elongate oval spot; the 
humeral line rather broad posteriorly, but becoming very 
slender; the sides with three black lines, of which the 
first two become confluent towards the legs; inter-alar 
portion black, spotted with pale blue. Abdomen black ; 
the upper side of the first six segments pale blue, with 
black sutures, and on the 2nd to 6th there is a triangular 
black expansion near the posterior end of each. Legs 
black; the femora brownish internally at their base. 
?. Unknown. 
Length of abdomen, 32 mm. Length of posterior 
wing, 26mm. Expanse, 57 mm. 
The neuration is more simple than in any other 
known species of the genus. 
N.B.—A species from Brazil, C. brasiliensis, Hagen, 
has never been described. 
AGRIONINA. 
Légion Pseudostigma. 
The following species of this Légion were found by 
Mr. Buckley :— 
Anomisma abnorme, M‘Lach. 
A. abnorme, M‘Lach., Ent. Month. Mag., vol. xiv., 
p- 87, male; Microstigma terminatum, Id., l.c., 
female. 
As already noticed, the type specimen from which I 
described M. terminatum is much mutilated, and the 
base of the wings wanting; from this cause I did not 
recognise it as the female of A. abnorme, which it 
certainly is. 
I have now fifteen individuals of both sexes before me. 
In fully adult examples the dark band preceding the 
opaque yellow apex of the anterior wings is somewhat 
broader than in the less adult typical male specimen, and 
it is darker. In immature examples of both sexes this 
dark band is scarcely indicated. In the female the small 
white spot at the apex of the posterior wings is liable to 
become obsolete in fully adult examples. 
The normal number of nervules in the quadrilateral is 
two in both pairs of wings; there are never less than 
two, and very rarely three.
