^r •!(! liyiiopvf^iiini very complicated in structure, the niosal 

 ami api(;al faces of the [)leurites produced into h)hcs ; cij^hth 

 sternite beaiiug two apical rows of spines. Ovipositor with 

 the tcri^al valves very short, strongly upenrved, with a basal 

 spur or tooth on tiie dorsal side. 



Tvpe of the subgenus: — Limnophila howesi, sp. n. (New 

 Zealand). 



The group also inclndis LimnophJla mirijica, Alexaiuler 

 (North Island), L. nigroapicata, sp. n., and L. prodiicta, sp. n. 

 The very peculiar structure of tlie ovipositor probably indi- 

 cates a specialized method of egg-laying.
