GENUS NEONEURA (oDONATA) 
colored Xeoneui'a, but' in flight and alertness it is similar to its 
congeners. The detailed description has been prepared because 
the only other published description, that of de Selys, seems to be 
based on badly discolored material. 
Neoneura sylvatica Selys (Figs. 6, 37, 38, 39 and 79.) 
I have seen the three males in the Carnegie (Museum.® Before 
I had seen these specimens I could scarcely believe de Selys’ de- 
scription was accurate, and I thought the original material was 
])robably faded or discolored and therefore misleading. Such is 
not the case, and this is certainly an odd and beautiful species, 
with its blue thorax and basal abdominal segments with the re- 
mainder of the abdomen bright red. The break in the two colors 
is abrupt, taking place at the interrupted narrow subapical dark 
ring on the third segment. 
Neoneura ethela new species (Figs. 7, 42, 43 and 80.) 
Abdomen, cf 26.5 min.; hind wing, d' 18.5. 
d - — Genae light blue or green. Labrum and rhinariimi olive, the former 
paler and yellowish along lower border, a median posterior black spot and the 
sides extensively black except below. Nasus black, a small yellowish spot on 
either side near the posterior border. Frons in front blue or green. Head above 
olive or bluish, intricately patterned with black as follows: median ocellus 
surrounded with black with two short posterior bars inside the lateral ocelli 
and extending slightly beyond them, where the bars are transversely joined in 
the median line; from the median ocellus, on either side a bar runs outward, 
then forward and outward over the inner face of the second joint of the an- 
tenna; in front of the ocellus are three broad bars, one median, reaching the 
anterior edge of the frons, and one on each side running outward and forward 
to the anterior lateral edge of the frons, then backward and outward to the 
inner face of the second joint of the antenna; from the lateral ocellus, and nar- 
row'ly separated from the black behind it, a bar runs outward and forward to 
end against the eye; posterior to this and also touching the eye is a large round 
spot; posterior to this round spot is a transverse bar of black, not quite 
reaching the eye, and ending at the extremity of the occipital crest. Antenna 
brown, excepting inner face of second joint which is black. Rear of head yel- 
low above, remainder black with the lower part adjoining the mouth parts and 
a narrow margin at the eyes, pale, yellowish above, greenish or bluish below. 
Front lobe of prothorax black, anterior border and a posterior spot on either 
side, yellowish; middle lobe olive, a wide median longitudinal line, and an 
oblique bar the full length on either side, the two converging anteriorly; hind 
lobe black, very narrowly pale margined posteriorly. Propleuron olive or 
yellowish, black margined above and in front. 
Thoracic pale colors blue or slaty, paler below.
