fuscous for basal fourth of costal space and also around pterostigmatic • 
veinlets ; the basal third of cubital space also marked in the same way.

Zelandoperla maculata (Hare). (Figs. 15, 14d.) 
Leptoperla maculata Hare, Trans. N.Z. Inst., vol. 42, p. 29, 1910. 
This species appears to be fairly closely allied to the preceding one, 
but may be distinguished from it by its smaller size (expanse 22 mm. to 
27 mm.), longer antennae and cerci (the latter being as long as the 
abdomen), paler and more greyish coloration of forewings, and by the much 
narrower oval-shaped patches surrounding the distal veinlets (fig. 15). 
The pronotum is more rectangular in shape, and has the median longitudinal 
groove narrow for its whole length (fig. 144). 
Type in Mr. Hare's collection. 
Locality.—Karori and Wainuiomata, near Wellington.

Superficially resembling Z. decorata n. sp., but can easily be distinguished 
from it as follows: Forelegs blackish, tibiae with a band of brown on 
in fig. 16, but mostly more or less rectangular.  Hindwin pale semi- 
transparent grey, tinged with brownish along basal two-thirds of costa and 
also basally along Cu. In this species also the basal joint of the antenna is
