Q. Differs from the male as follows :—Pale antehumeral stripe present, from one-fourth to equally as wide 
as the mid-dorsal, which is less brilliant than in the male. Humeral stripe deeply forked for its upper 
two-thirds, lower third somewhat wider than the pale antehumeral, or the humeral stripe proper may be 
present only on the upper half of the humeral suture and unconnected with the mesepimeral, which is 
half as wide as the pale antehumeral. Dorsum of segment 2 black, with an elongated, pale, elliptical, 
median spot, contracted behind into a line or rounded prclongation, sides pale, with an inferior black 
stripe ; 3-7 black, with a pale, transverse, basal ring, which may or may not be medially interrupted, and a 
pale, mid-dorsal, longitudinal stripe, confluent or not with the basal ring and occupying the basal five- 
sixths or less ‘of 3-5 or 6; 8 and 9 blue, each side with a superior and an inferior stripe black, the latter 
as long as the segments, the former on 8 as long as the segment, or reaching from the base to two-thirds 
of the way to the apex, as it does on 9; dorsum of 10 blue.

—CotompBia (Thorey, M. C. Z.: 1 faded male probably belonging to this species). 
The specimens from Eastern Mexico were taken between March and June, those 
from Western Mexico in September and October. 
The females here referred to 4. @nea are much like those of A. translata and of 
A. cuprea, but differ from both of these in having the external angle of the pterostigma 
more acute (as is the case in A. wnea, 3), and from A. translata, 2, by segment 10 
being pale on the dorsum. A. wnea, 9, also resembles A. oculata, ¢, but the meso- 
stigmal lamine are differently shaped (cf. Tab. IV. figg. 10, 11).
