MOSQUITO NOTES— II. 79 



My previous use of the name Cyathomyia in the sense of Protomelanoconion, 

 Theobald, proves therefore to be erroneous ; if the group is retained as a distinct 

 subgenus of Ciilex, Theobald's name will have to be revived, Cyathomyia falling as a 

 synonym of Lophoceratomyia. However, C. brevipalpis, Giles, and P. fiiscmn, Theo., 

 have a hypopygium constructed much as in Neocidex, Dyar, and should probably be 

 referred to that subgenus. 



Rachisoura filipes (Walker). 



CitlexfiUpes, Walker, Proc. Linn. Soc. v, p. 229 (1861). 



Rachisoura sylvestris, Theobald, Mon. Cul. v, p. 208 (1910). 



Stegomyia hilli, Taylor, Proc. Linn. Soc. N.S.W. xxxix, p. 456 (1914). 



Mimeteomyia hilli, Taylor, Proc. Linn. Soc. N.S.W. xli, p. 566 (1916). 



The above synonymy appears to be proved by a comparison of Walker's and 

 Theobald's types with a specimen of S. hilli from Stapleton, Northern Territory, 

 sent by Mr. G. F. Hill. The genera Rachisoura and Mimeteomyia are probably not 

 distinguishable ; they differ from Rachionotomyia in the shorter and stouter proboscis, 

 which is little, if any, longer than the front femora. 



Rachionotomyia aenea, sp. nov. $. 



Head dark-scaled, with a moderately broad pale band in front, which is blue or 

 whitish according to the direction of the light. Palpi and proboscis purplish-scaled, 

 the palpi exceeding the clypeus by about twice the length of the latter. Antennal 

 torus orange. Thorax with the integument orange-brown, darker brown on the 

 mesonotum. Prothoracic lobes with black bristles and narrow, almost hair-like, 

 dark brown scales. Mesonotum with narrow dark brown scales, except on, and just 

 in front of, the scutellum and between the scutellum and the wing-bases, where the 

 scales are broad, fiat and bronzy-green in colour. Pleurae with a large silver-scaled 

 dark brown patch. Abdomen purphsh-black above, golden beneath, the tergites with 

 lateral subapical bluish-silvery patches. Legs purplish-scaled ; middle femora in 

 front with a silvery streak on the basal half and a silvery subapical spot ; front and 

 hind femora unmarked. Wings with dark brown scales ; those on the fork-cells 

 short and rather broad. Upper fork-cell slightly longer than its stalk, its base ^ 

 distinctly distal to that of the lower. Cross-veins separated by more than the length 

 of the posterior. Wing-length 3 mm.

Allied most nearly to R. similis, Leicester, differing in the unspotted front and hind 

 femora, and in some other points. 



Rachionotomyia purpuraia, sp. nov. $. 



Nearly aUied to R. bimaculipes (Theobald), differing as follows : — Integument of 

 mesonotum orange, almost dull (instead of shining blackish), clothed with narrow 

 greenish scales mixed with some black ones ; pro-epimera with small flat black scales 

 (bare, perhaps rubbed, in R. bimaculipes) ; dark scales of abdomen with strong purple 

 reflections (instead of dull black).
