586 NEW OR LITTLE-KNOWN SPECIES OP AUSTRALIAN TIPULIDAE, i., 



long deflection of E4-1-5; cell Mi tending to become evanescent, lacking in tbe 

 left wing of the type; basal deflection of Cm a little more than one-half its 

 length beyond the fork of M. 



Abdomen with the first tergite shiny black ; remainder of the abdomen deep 

 reddish-brown, the hypopygium darker. 



Hab. — Victoria. 



Holotype, S, Ararat (G. F. Hill). 



Stibadocerella australiensis, n.sp. 



General colouration pale brown; pleura yellow with a transverse dark brown 

 girdle on mesepisternum; terminal tarsal segments white; wings greyish-yellow; 

 macrotrichiae in distal end of cell R5; t present, without macrotrichiae; cell 1st 

 M2 open by the atrophy of the outer deflection of M3 ; abdomen bicoloured. 



$. Leng-th, 9.6 mm.; wing, 8 mm.; antenna about 12 mm. 



Rostrum and palpi pale. Antennae of the male very long, the small scapal 

 segments yellow, the flagellum dark brown, except the basal three-quarters of the 

 first segment which is obscure brownish-yellow. Head brown. 



Pronotum pale whitish-yellow. Mesonotum dark brown, the three usual 

 praescutal stripes a little paler; lateral margins of median sclerite of postnotum 

 a little more darkened. Propleura light yellow. Mesopleura yellow, the sternum 

 and mesepisternum dark brown, giving the pleura the appearance of being trans- 

 versely girdled; mid- ventral area of sternum pale. Halteres very long, brown. 

 Legs with the coxae and trochanters yellow; femora dark brown, paler basally; 

 remainder of legs dark brown, the tips of the posterior metatarsi and the remain- 

 ing tarsal segments snowy- white; most of the other legs are detached but in what 

 would seem to be the fore and middle legs all the metatai-si and the basal half of 

 tarsal segment two are darkened. Wings with a uniform greyish-yellow tinge ; 

 veins dark brown. Venation: Sc ending about opposite six-sevenths the length 

 of Rs, both Sci and Sc2 subobsolete; Rs elongate, gently arcuated at origin; tip 

 of Ri entii'ely atrophied, the appai-ent r (which is presumably the free base of 

 R2) is preserved, but entirely without macrotrichiae; petiole of cell Rs short, 

 less than the basal deflection of Mi.^2; r-m, very long, one-half longer than the 

 basal deflection of Cm; cell 1st M2 open by the atrophy of the outer deflection 

 of . M3 ; basal deflection of Cm about two-thirds its length beyond the fork of 

 M ; a row of macrotrichiae in the distal third of cell Rg ; a few macrotrichiae in 

 the outer end of cell M2. 



Abdomen bicoloured, dark brown, the apices of the basal segments broadly 

 paler; on the subterminal segments the colouration is uniformly dark brown. 

 Hypopygium dark brown.

 • This conspicuous genus of crane-flies had not hitherto been recorded from 

 Australia. 



Platyphasia eegina, n.sp. 



Legs brownisli-yellffw, the tips of the femora and tibiae narrowly blackened ; 

 wings with R2+3 and Rs subequal; r-m present or obliterated by the fusion of 

 R4+5 on M1 + 2; cell Ml usually sessile.
