new or little-known Tipulidee. 513 
M:le hypopygium very complicated in structure, the mesal 
and apical faces of the pleurites produced into lobes ; eighth 
sternite bearing two apical rows of spines. Ovipositor with 
the tergal vi ae: very short, strongly upeurved, with a basal 
spur or tooth on the dorsal side. 
Type of the subgenus :—Limnophila howest, sp. n. (New 
Zealand). 
The group also includes Limnophila mirifica, Alexander 
(North Island), L. nigroapicata, sp. n., and L. producta, sp. un. 
The very peculiar structure of the ovipositor probably indi- 
cates a specialized method of egg-laying.
