Holntype, S , Ohakune, altitude 2060 feet, January 18^ 

 1922 (r. R. Harris). 



Allotype, ? , Ruapehu, between Ohakune and Camp,

Limnophila otagensis, sp. n. 



Allied to L, cinereipleura ; wing of male over 6 mm. ; 

 mesonotum and pleura brown ; basal deflection of Cui 

 beyond the fork of M. 



Male. — Length 5 mm. ; wing 6'2 mm. 



Most closely related to the smaller L. cinereipleura, Alex. 



Rostrum and palpi dark brown. Antennae brownish 

 black, short, with conspicuous verticils. Head greyish 

 brown, clearer grey on the anterior part of the vertex. 

 Mesonotum brown with a sparse brownish-yellow pollen, the 

 prsescutum with indistinct darker stripes. Pleura brownish 

 testaceous, with no distinct tinge of grey, but with a slight 

 indication of a darker longitudinal stripe. Halteres yellow. 

 Legs with the coxse and trochanters brownish yellow ; 

 remainder of the legs brown, the terminal tarsal segments 

 black. Wings similar in colour to those of L. cinereipleura ; 

 cell Ml larger ; basal deflection of Cui beyond the fork of 

 M a distance approximately equal to one-third its length. 

 Male hypopygium with the outer pleural appendage only a 

 little longer than the inner appendage, unarmed. Gouapo- 

 physes appearing as very strongly curved horns, as in this 

 group of species ; penis-guard with the shoulders rounded.

Limnophila angusta, sp. n. 



Male. — Length about 4 mm. ; wing 4*8 mm. 



Related to L. cinereipleura, Alexander, and L, deviata, 

 Alexander, diff'ering as follows ; — 



Wings very narrow, pale brownish yellow, the stigma 

 almost lacking. Venation : r faint, on K2 about its own 

 length beyond the fork of i?2+3j and consequently far 

 removed from the tip of i?i ; R^ beyond r straight, R^ 

 diverging from it, so celljR2 at the wino-margin is much 

 wider than cell 2nd R^ ; cell Mi small ; all the cells of the 

 wing are conspicuously narrowed, due to the shape of the
