stem about one-fifth its length. Supernumerary cross- vein slightly 

 nearer base of wing than the mid cross-vein, posterior cross-vein 

 about two and a half times its own length distant from the mid 

 cross- vein. 



Length 5 mm. 



J/aiifaL— Tasmania. 



Ohservations. — Described from four females, all rather 

 damaged. 



Genus Andersonia, nov. gen. 



Head clothed in the centre with narrow curved and upright 

 forked scales, and at the sides with flat scales as in Culex. Female 

 palpi of four segments as in Culicada. 



Thorax clothed on the greater part with narrow-curved scales, 

 but on either side just before the wing-roots is a patch of flat and 

 broad spindle-shaped, scales. Scutellum with narrow-curved scales. 

 Abdomen with flat scales. Wing venation and scales similar to 

 Culicada. 



Male unknown. 



One species only is known at present and is found in 

 Tasmania. 



This genus appears to be closely related to Culicada, from 

 which, however, it can at once be separated by the presence of 

 flat lateral scales on the thorax. 



Andersonia tasmaniensis, n. sp. 



2 . Head black, clothed with light golden 

 small narrow curved scales, numerous simi- 

 larly coloured upright forked scales, and cream 

 coloured lateral flat scales. There are very 

 few bristles on the head. Eyes bronzy. An- 

 tennce with basal segment and basal half of 

 second segment testaceous, the remainder 

 dark. Palpi with very small fourth segment, 

 somewhat densely scaled. Proboscis all dark 

 in colour. 



Thorax dark brown, clothed on the median 

 area with small narrow curved scales, which 

 are mainly of a dark brown colour ; there is, 

 however, a lighter median line of more golden 

 brown scales on the apical three-quarters of 

 the thorax ; the basal quarter of the thorax is 

 devoid of scales in the centre. There is, how- 

 ever, a narrow line of golden brown scales on 

 either side of this area, bounded laterally by 

 another small bare patch, which extends al- 

 Female palp of Ander- most to the wing-root. The apical lateral 

 so7Ma iasmanimsis, denuded third of the thorax is clothed with large 

 ot scales. golden yellow narrow curved scales, which lie 



with their apices toward the centre of the thorax. Just in front of, 

 and extending to, the wing-roots is a very conspicuous patch of large
