GENUS NEONEURA (oDONATA) 
Abdomen black above; a wide apical yellow spot on segment one; a wide 
3'ellowish-green median longitudinal stripe on two, wiilening basally but not 
quite reaching the base of the segment, subapically constricted or divided, 
forming a subapical round spot; three similar, but the narrow basal black 
ring of segment two represented by a small median basal sjjot only; four 
similar, the dorsal stripe narrower except at the base, and the subapical 
portion reduced to a median line; five similar, with the median stripe still 
more reduced, the subapical part a vestige only; six similar, the exj)anded 
base of the pale longitudinal median stripe persisting, but otherwise scarcely 
discernible except at its subapical end; seven similar to six, the base yel- 
lowish-green and with a subapical median narrow yellow sj)ot; eight con- 
spicuously yellow wuth an irregular subapical spot on either side and a 
narrow apical ring, black, the two subapical spots sometimes joined to 
form an apical quadrangular spot, continuous with the apical transverse ring; 
nine black, a subapical yellow spot on either side below; ten black. Seen 
from the side, segments one and two with the lower half yellow, one with its 
lower posterior border more or less dusky; three to six with the lower border 
broadly pale or greenish yellow, progressively narrower posteriorly, espe- 
cially at the apex of the segments; seven below more broadly dark yellow; 
eight entirely yellow, except for the apical black described in dorsal view; 
nine black, except for yellow spots described in dorsal view, and a v^entral 
prolongation of these which reaches the lower border; ten black. Ventral 
suture black, except on eight to ten where it is dull yellow. Sui)erior appen- 
dages black, ])aler basally; inferiors yellow', slightly darker apically. 
Legs bright clear yellow', the posterior external face of the femora and the 
anterior external face of the tibiae slightly dusky, most marked on the first 
legs and least on the third; apices of femora, spines and the tips of the tarsal 
claws, black; tooth on tarsal claw' about as in esthera. 
Vdngs clear or slightly tinged; stigma yellow'ish brow'n or brow'n, covering 
very slightly less than one cell, its costal length equal to or slightly greater 
than tw'ice its width. Of wings examined, in one case the descending cross- 
vein from the subnodus does not reach the wing margin, but stops at Ciu. All 
terminations of Cui, A, and the descending cross-vein from the first postnodal 
are normal. 
9. — Genae gray. Labrum, rhinarium and nasus light yellowish Ijrown; 
labrum paler below', a median basal dark or black sj)ot; nasus with a black 
spot on either side and a median longitudinal dusky bar. Frons in front ])earl 
gray, yellow'ish tinged. Frons above and vertex olivaceous pearl gray; tw'o 
dusky spots in front of the median ocellus rei)resent the apices of the lateral 
branches of the l)lack trident of the male; below' (anterior to) the antenna is a 
dark sjjot against the eye; about half w'ay between the lateral ocellus and the 
eye a narrow dusky or black line starts, and runs outw'ard and forward against 
the eye, which has a narrow' dusky or black border posterior to this jioint; a 
dusky spot at each end of the occipital crest; outside and slightly posterior to 
this a short transverse dusky bar equally separated from the spot on the occipi- 
tal crest and the eye. Antenna with second joint gray on its outer face, 
tlark or black on the inner, nearly w'hite at the apex; remainder brown, the
