veins, as well as a coarse rugosity of the wing membrane, not men- 
tioned or shown by Riek. However, the fossil is still very fragmentary 
and although it might well be homopterous, its family position is 
most obscure. 
Two additional fossil insects from Antarctica, one Jurassic and 
the other Permian, have been sent to me for study. Both are suffi- 
ciently well preserved to justify formal description and naming. 
The Jurassic specimen is an odonate, collected from a pond deposit 
within the so-called Mawson Tillite on Carapace Nunatak, South 
Victoria Land. 2 It belongs to the suborder Anisozygoptera, which 
was a major one in the Jurassic Period, and to that complex of 
families which includes the Liassophlebiidae. The general vena- 
tional pattern, the nature of the arculus, nodus and pterostigma, as 
well as the curvature of CuP and iA, are very similar to those of 
Liassophlebia . There are some differences in the nature of the 
antenodal cross veins but, all details considered, it seems advisable 
to broaden our concept of the family Liassophlebiidae to include the 
antenodal structure of the Antarctic species, for reasons given below, 
rather than to establish another family. The new specimen does 
clearly represent an undescribed genus and species. 
Garaphlebia Carpenter, new genus 
This is related to Liassophlebia , but the hind wing has several 
weak antenodals in addition to the two strong, primary ones. The 
venation is much like that of Liassophlebia (see figures 1 and 3) 
but the cross veins between R2 and R3, proximally, are long and 
apparently not interrupted by transverse connections; the space be- 
tween MP and CuA is very narrow; IR2 apparently arises more 
distally than in Liassophlebia ; and the anal area of the wing is small. 
The shapes of the discoidal cell, subdiscoidal cell, CuP and iA are 
very much as in Liassophlebia.

Hind wing: length of wing, 40 mm; width, at level of arculus, 
8 mm. Primary antenodals very well developed, the costal and sub- 
costal elements aligned; the other antenodals weak and indistinct, 
but under glycerin-alcohol eleven are visible in the costal area and 
seven in the subcostal area, none aligned ; pterostigma long and 
2 Basaltic lavas enclosing the fossiliferous pond deposit are presently being 
dated by the Potassium/Argon method.
