it corresponded exactly with the curved outline of the dark 
apical band. 
Order ODONATA, Suborder Zygoptera 
Family Epallagidae 
Genus Litheuphaea nov. 
Venational characters of the wing similar to those of 
genus Euphaea Selys, differing only as follows: Nodus 
situated rather more basally (although the level of this 
differs within limits in both subgenera and species of 
Euphaea; the present specimen conforms in this respect 
most closely to Anisophaea Fraser) ; pterostigma much 
larger than in any recent species of Euphaea, very acute 
proximally, as in many species of the Megapodagriidae, and 
fusiform in shape, followed by two rows of cells distally

between the costa and radius; discoidal cell entire and 
very short in view of the length of the wing; anal-vein, 1A, 
extending beyond the level of nodus ; anal field immediately 
posterior to the discoidal cell made up of three rows of 
cells (only a single row at this level in Euphaea), the rows 
of cells separated by an irregular zigzagged vein which is 
evidently a vestigial recurrent anal-vein (absent or en- 
tirely vestigial in Euphaea but becoming strongly developed 
in the more recent Agriidae. (In this respect, the new 
genus establishes a link between the Epallagidae and 
Agriidae.) Other characters are as follows: Antenodals 
numerous and with their costal and subcostal portions in 
strict alignment; Rii not approximated nor confluent with 
the radius at its origin; Riii in continuation with the sub- 
nodus; longitudinal veins rather flat and not curved abrupt-
