Alexander — Crane Flies 257 



Hah. Tasmania (A. Simson, No. 3846). Type, I. 12170. 



PLUSIOMYIA TRIPECTINATA sp. nov. 



Similar in general appearance to P. pandoxa; flagellar segments two to six 

 with a slender pectination beyond midlength of eacli segment, in addition to the 

 usual basal pair; wing-pattern heavier, especially in the anal cells. 



S Length, 25 mm.; wing, 24-5-26 mm.; abdomen alone, 18 mm. 



Very similar in general appearance to P. pandoxa, differing as follows : 



Basal flagellar segment with a slender finger-like lobe immediately before 

 the tip ; segments two to six, in addition to the slender basal branches, with a 

 shorter but conspicuous third branch just beyond midlength of the segment; 

 seventh flagellar segment without the apical branch and apparently with but a 

 .single basal branch. Stripes on the praescutum duller grey. Wings narrower ; 

 the wing-pattern very similar to that of P. pandoxa, the chief differences as 

 follows : The white band in cell R^ is narrowly interrupted by a brown line 

 before the fork of M^^-; the posterior ray from cell first M^ does not reach the 

 posterior margin, but ends at near midlength of cell M^ ; outer ends of the anal 

 cells brownish-grey, heaviest along vein second A; a whitish ray in cell first A 

 reaching the Aving-margin near vein second A ; cell Cu hyaline with the distal end 

 and a mark at two-thirds the length narrowly brown. Abdomen shorter, the 

 lateral margins darker. 



Hah. Tasmania: Magnet, Waratah (A. M. Lea). Type, 12171. 



The antennal structure is very distinct from that in other members of the 

 gracilis group. 



PLUSIOMYIA (?) FELIX sp. nov. 



Mesonotum light grey, the praescutum with three reddish-brown stripes; a 

 conspicuous tubercle on the lateral sclerite of the postnotum before the root of 

 the halter; wings greyish-subhyaline, the cord and longitudinal veins narrowly 

 seamed Avith brown ; abdominal tergites reddish-brown, the lateral margin of each 

 segment with silver-grey triangles. 



S Length, 26 mm. ; wing, 24-3 mm. 



Frontal prolongation of the head reddish ; palpi dark brown. Antennae with 

 the scapal segments reddish-brown (flagellum broken). Head with the vertex 

 behind the antennal bases shiny-reddish ; remainder of the vertex dusky-grey, a 

 little more reddish adjoining the inner margin of the eyes. Mesonotal prae- 

 scutum light grey with three conspicuous reddish-brown stripes that are weakly 

 pruinose ; median stripe split by a capillary line of ground-colour except at the 

 posterior end; scutal lobes and lateral margins of the scutellum largely reddish; 

 median area of scutum and scutellum light grey-pruinose ; postnotum reddish,
