Gymnastes Brun., is regarded by Alexander, perhaps with reason, as a 
subgenus of Paratropeza. 
Aphrophila and Astelobia are proposed respectively for Gnophomyia 
neozelandica n. sp. and G. rufa (Hudson); in neither ease is any other 
species known. 
Gnophomyia (Aphrophila) neozelandica n. sp. (Fig. 47.) 
9. Body short and stout, blackish, more or less dusted over with 
dark grey; a small shoulder-spot, an area round the wing-base, and the 
ovipositor ochreous. Front very narrow, about one-tenth as broad as 
Sc, oblique, slightly longer than Se,. Cross-vein 7 vertical, shorter than 
tip of R,, joining R,;, well before base of Rẹ. Discal cell confluent with 
cell M,. Halteres ochreous. Length of body, 10mm.; wing, 13 mm. ; 
hind leg, 19 mm. 
Sourn Istanp: Otira Gorge, resting on boulders close to water’s edge 
amongst the foam, Warnock’s Creek (G. V. Hudson, No. 232). The 
habits suggest that the species has an aquatic larva ; if this is so, it would 
confirm the separation of the species from Gnophomyia. 
Gnophomyia (Astelobia) rufa (Hudson). (Fig. 48.) 
Tipula rufa Hudson, Trans. N.Z. Inst., vol. 27, p. 294, 1894. 
Gnophomyia rufa Hutton, Trans. N.Z. Inst., vol. 32, p. 39, 1900. 
Gnophomyia rufa Hudson, Trans. N.Z. Inst., vol. 52, p. 32, 1920. 
Legs longer than in G. neozelandica, but hind tarsi much shorter than 
tibiae. Sc, vertical, shorter than Sc,. Cross-vein r very oblique, much 
longer than tip of R,, joining R, well beyond base.  Discal cell closed. 
Length of body, 5 24 mm., 9 29 mm. ; wing, 4 19 mm., $ 21 mm. ; hind 
leg, d 49 mm., ? 52 mm.

According to Hudson, the early stages are spent in semi-liquid detritus 
between the bases of the leaves of the epiphytic plant Astelia Solandri.* 
The larva and pupa figured by him difier very markedly from those 
. of the genotype (G. tristissima O.-8.), and thus support the separation of 
this species from Gnophomyia s. str | :
