Genus Stenopeela, McLachlan (1866). 



The two first joints of the maxillary palpi are short, equal, 

 broad ; the others smooth ; the third and fourth are each 

 twice the length of the second ; the fifth is shorter than the 

 fourth. Antennae short and slender. Wings when at rest 

 surrounding the body ; the anterior much narrower than the 

 posterior, elongated ; the transverse nervules are numerous 

 and evenly distributed ; the posterior wings three times as 

 broad as the anterior, plicated, the transverse nervules dis- 

 tributed pretty evenly over the whole surface. 



Distribution. — New Zealand.

Green, depressed ; head hardly broader than the thorax, 

 Prothorax subtransverse, the front margin nearly straight, 

 rounded posteriorly. Caudal setae 13-jointed. Wings pale- 

 green. Length, 18-20 mm. ; expanse of wings, 50-58 mm. 

 Locality. — Throughout New Zealand.

Black. Head scarcelj^ depressed ; antennae with 40 joints, 

 strong, submouiliform, scarcely shorter than the body, the 

 joints subovate. Prothorax subtransverse, acutely angled, 

 nearly quadrate, not much broader than the head. Caudal 

 setae very short, incurved, 14-jointed. Tibiae banded with 

 yellow. Wings blackish, semi-opaque, densely reticulated. 

 Expanse of wings, 25 mm. 



Locality. — New Zealand. 



This species is not a Chloroperla nor a true Perla, nor is it 

 a Stenoperla. Probably it belongs to a new genus, but well- 

 preserved specimens are wanting for description. It is easily 

 distinguished by its yellow tibiae. 



Genus Leptoperla, Newman (1839). 



Exterior portion of the fore wing with six strong parallel 

 nervures, of which the fourth is forked at the extremity and 

 the fifth unites with the fourth before its furcation; these.
