456 Mr. T. D. A. Cockerell on Fossil Arthropods 
I. 8901 (Brodie collection). Very lke 7. splendens, 
Brunetti, agreeing in the venation. It also greatly resembles 
T. tessellatipennis, Brunetti. 
Megistocera gurnetensis, sp.n. (Fig. 3.) 
Wing hyaline, with colourless veins ; a dusky stigmatic 
spot, and two others below it. Stigma to end of wing 3°8 
mm.; origin of Rs to end of wing 5°2 mm.; width of wing 
3°] mm. 
Megistocera gurnetensis, sp. 0. 
In 17090 (A’Court Smith). Compared, at Mr. Edwards’s 
suggestion, with Dolichopeza and Megistocera. It agrees 
much better with the latter, and can well be congeneric with 
M. fuscana, Wulp. The second basal cell differs, being in 
the fossil more as in Tipula. 
Gymnastes fasciatipennis, sp.n. (Fig. 4.) 
Wing slightly over 3 mm. long, with three broad dark 
grey bands (the third apical), alternating with narrower 
hyaline ones, the middle hyaline one narrowest in middle.
