of this specimen of ornata , but it is not only not the same specimen, 
but it is a distinct species, described below as lehmani. 
The type specimen of ornata is a reverse impression, with an in- 
distinct pattern of color on the wings. In all probability, the wing 
membrane was dark with transverse light bands. The first three 
segments of the abdomen are narrow and rather indistinct; the ovi- 
positor, in part hidden between the cerci, has previously been over- 
looked. Homaloneura ornata was figured in reconstruction by Hand- 
lirsch (1921); the details shown by him are highly imaginary and 
probably incorrect ; his figure, for example, shows the prothoracic 
lobes absent, which is almost certainly incorrect, since they are present 
in all other species of the genus. 
Wings unequal in length, the hind pair being longer; membrane 
relatively strong, dark, probably with transverse light bands. The 
cuticular thickening strengthening Ai for a short distance at the 
point in which it bends towards the posterior margin ; the supporting 
cross vein, r-m, weak, running obliquely from the stem of M to the 
very base of Rs. Main veins with few branches. Fore wing: length 
about 20 mm, width 7.5 mm ; broadest shortly beyond the midwing, 
markedly narrowing towards the base; apex pointed, directed poster- 
iorly; anterior margin concave at about midwing; posterior margin 
with a convexly curved portion just before the apex; Rs with six 
simple branches, MA forked 1-2 times; MP simple or with a long 
fork; CuA well developed, with 3-5 pectinate branches, which are 
obliquely arranged. CuP simple or forked ; about eight simple anal 
veins; cross veins few and weak. Hind wing: length 23 mm, width 
about 10.5 mm; anal area very much expanded just beyond the wing 
base, the posterior margin forming nearly a right inner angle. 
Body structures: Head with large, projecting eyes; clypeus ap- 
parently oval ; prothoracic lobes unknown ; mesothorax slightly shorter 
than the metathorax. Abdomen, length: 16 mm, relatively slender; 
tergites with projecting posterolateral angles; the segments 1-3 very 
short, segment 6 longer than the others; ovipositor heavily sclerotized; 
longitudinal lateral lines on each tergite; cerci robust, completely 
covered by short hair. 
H. ornata belongs to the group j oannae-lehmani, all of these being 
small in size with simply-marked wings. Within this genus, ornata 
shows the highest modification in the wing shape, and has the most 
extensively broadened hind wings.
