156 THE ENTOMOLOGIST. 



Cnlex nocturnax, Theobald (Mono. Culicidae iii., p. 159), was 

 received from Dr. Hall and taken at Ba, where it was found 

 active at night in houses. It can be told by the abdominal 

 ornamentation, the ground colour deep brown, the base of the 

 second, third, and fourth segments having white bands, the 

 fifth and sixth with white basal median patches, constricted 

 in the middle, the sixth and seventh with narrow apical yellow 

 bands, laterally are median white spots, and the venter is 

 ochreous. The legs have basal pale bands, which are narrow on 

 the fore and mid pairs, broad on the hind, and the ungues of 

 the two front pairs are uniserrate, whilst those of the hind 

 are simple. 



These characters will at once separate it from the ^ew 

 species of Culex, described here (C. jepsoni). The specimens 

 sent were taken in April, May, and June. 



With regard to Stegomyia scutellaris, Walker, I do not feel 

 certain. Some much rubbed specimens sent me were taken to be 

 that species, but I noticed at the time that there were three 

 more or less parallel white scaled lines on the sides of the 

 thorax. On comparing Mr. Jepson's specimens, I find they are 

 distinct from the true S. scutellaris of Walker, and I have 

 described them here as a new species. 



The original record of scutellaris for these islands was made 

 on some specimens sent to the British Museum by Mr. B. G. 

 Corney (Mono. Culicidse, iii., p. 144, 1903), who also sent the 

 following note: — "Diurnal mosquito, disappearing entirely at 

 night, taken in a wooden hut five yards from high water line of 

 sea coast, on sandy soil, forest adjoining and high land ; locality. 

 Island of Bega." 



Walker's species can easily be told by its having the sides 

 with white puncta, not lines, and by the basally white banded 

 abdomen and longer wings ; otherwise, the general appearance 

 is very similar. 



Culex fatigans, Wiedemann, is the common brown, unbanded- 

 legged household mosquito, which seems to occur like S.fasciata 

 all over the tropics and sub-tropics, and on most oceanic islands. 



One specimen sent by Mr. Jepson near Culex jepsoni, nov. 

 sp., was too damaged to describe, but is apparently distinct, 

 having an ochraceous scaled venter to the abdomen. 



Stegomyia pseudoscutellaris, n. sp. 

 Head black, with white median line and a white patch on each 

 side. Thorax blackish brown, with brown scales, a narrow median 

 white line, a thin white line on each side above pleura, extending 

 lateral from the head to root of wings ; pleura bright brown, with one 

 long and one short parallel white lines, which are also parallel with 

 the one above the pleura. Abdomen black, unhanded above, but with 

 curved white spots ending about the middle of the segments ; basal 

 white bands ventrally. Legs black, with narrow basal white bands
