GENUS NEONEURA (oDONATA) 
obscure, at least in dried material with more or less dark in ill-defined pattern. 
Ventral suture black. Appendages dull dark red, superiors tending to black 
above and apically. 
Legs light brown with very variable markings; femora and tibiae, espe- 
cially the femora, may be thickly spotted with dark, or the femoral markings 
maj’ be obscure or wanting, and the tibiae may be lined with black or be with- 
out markings, except the inner side of all the tibiae, which are invariably 
black (British Guiana). Darker, the first and second femora black dorsally 
except at the extreme base; ventral apical half of first femora black; most 
of the anterior dorsal surface of the first and second tibiae covered with a 
black line; hind femora heavily spotted (Pard). 
Wings clear or, in one specimen, slightly tinged with yellowish beyond the 
arculus; stigma light reddish brown to dark reddish brown, covering slightly 
less than one cell, its costal length equal to or slightly less than twice its 
width. 
British Guiana: all in 1912; Wisinar, January 30; Rock- 
stone, February 1; Tuinatuinari, February 9 and 11: a total of

Abdomen, c7 25.5 to 27 mm., average 26; 9 22.5 to 2.3.5, average 22.9:

cT. — Genae pale yellowish green. Labrum light or dark brownish red, 
paler below, a small black spot at center above. Rhinarium, nasus and frons 
in front and above similar to labrum or usually darker, almost black in some 
cases, nasus with a black, depressed spot on either side. Vertex brownish 
red, intricately marked with l)lack, varialile, ocelli surrounded by black, 
from the median ocellus a band usually runs outward and forward across the 
frons above, ending just inside the first joint of the antenna, this liand with 
two enlargements, one against the eye, the other midway, and sometimes with 
its inner end, next the ocellus, obliterated; from each lateral ocellus a band 
runs to the eye, this band usually with an anterior branch along the eye to the 
antenna; posterior to the ocelli is a T-shaped spot, sometimes wanting, the 
stem very short, and directed posteriorly or sometimes wanting; on either 
side of this, at the end of the occijutal crest, is a spot, midway between this 
spot and the eye is another spot, and in line with these two there is another 
spot against the eye; posterior to these spots on either side is a transverse 
bar of black which reaches the eye; rarely this bar and the two spots anterior 
to it, are more or less fused. Antenna brown, second joint darker with apex 
yellowish. Rear of head black, except a pale narrow border at the eyes. 
Prothorax reddish yellow; front lobe with a longitudinal black bar on the 
mid-line and one on either side; median lobe with a median black line and a
