NEW CULICID^ FROM WESTERN AUSTRALIA, ETC. 251 



creamy white, spindle-shaped, flat and elongated narrow-cvirved 

 scales ; the last-mentioned, together with similar coloured hairs, are 

 most numerous basally near the wing-roots. There are three distinct 

 rows of black bristles on the thorax besides lateral bristles and those 

 which surround the wing-roots. The central row terminates at the 

 commencement of the bare patch before the scutellum. Scutellum 

 with light yellow narrow curved scales. Prothoracic lobes with 

 light yellow narrow curved scales, and a few bristles. Pleurae with 



Thorax of Andei'sonia tasmaniensis, n. sp. 



creamy flat scales. Abdomen with flat scales. White basal lateral 

 spots on all segments. This character does not appear to be quite 

 constant, as in several specimens examined one or more spots were 

 absent, while in two specimens there were traces of complete white 

 basal bands on the second and third segments respectively. Ventral 

 surface of abdomen white scaled. Wings densely clothed with 

 brown C uUcada-like scales. First fork cell narrower and considerably 

 longer than the second posterior, its stem is not quite half its length. 

 Supernumerary and mid cross-veins almost in a line, the former 

 slightly nearer the wing base. Posterior cross -vein about its own 

 length distant from the mid cross-vein. 



Legs with femora, testaceous and clothed with mottled dark and 

 light scales, replaced apically by a spot of ochreous scales. Tibiae 

 darker, but also mottled. Tarsi dark and all dark scaled. 



Length 5"5-6"5 mm. 



Habitat. — Tasmania. 



Observations. — Described from eighteen females sent by Dr. 

 Anderson. There were no males. The species is very distinctive, 

 the sides of the thorax being distinctly lighter in colour than the 

 median area, and in this it superficially resembles Banksinella 

 luteolateralis (Theobald) ; the flat lateral scales, however, distin- 

 guish it at once from any other described genus.
