I 



Anopheles COStalis (Loew) Theobald. 



Females from Mauritius, where, according to d'Emmerez, the species is common, 

 are in the Paris Museum. 



Aedes (Stegomyia) albopicta, Skuse. 



Stegomyia k^^er^^, Ventrillon, Bull. Mus. Paris, x, p. 552 (1904) and Arch. Parasit. 

 ix, p. 441 (1905). 



Stegomyia scutellaris, Theobald et auct. {nee Walker). 



Ventrillon's types included both sexes, so that the identification of S. lamberti 

 is beyond doubt, notwithstanding the fact that Ventrillon states that the female 

 claws are toothed, whereas in all specimens I have examined they are simple. Either 

 Ventrillon made a mistake, or the species is variable in this respect, which is not 

 unlikely. 



This species also occurs at Reunion as shown by specimens in the Paris Museum, 

 collected at St. Denis, v-vi, 1913 (Surcouf). It has been recorded from Mauritius, 

 where it is said to be very common (d'Emmerez de Charmoy), It is surprising that 

 it does not seem to occur on the African mainland, since it has such a wide range 

 throughout the Oriental region. 



Aedes (Stegomyia) argenteus, Poiret (fasciata, Fb.). 



Culex insatiahilis, Bigot, Aim. Soc. Ent. France, (3) vii, p. 118 (1859). 



Bigot's description and figure can apparently only apply to this species, which is 

 common on the islands, especially near the coast (d'Emmerez de Charmoy), 



Aedes (Skusea) cartroni, Ventrillon. 



Stegomyia cartroni, Ventrillon, Bull. Mus. Paris, xii, p. 143 (1906), 

 This species, which. I had not previously seen, evidently belongs to the sub-genus 

 Skusea, although the male is unfortunately unknown. It is very close to S. pembaensis, 

 the type of the subgenus, so close indeed that it may eventually prove to be a variety 

 only. However in all the examples of S. pembaensis received at the British Museum 

 the abdomen is unbanded dorsaUy, and the scutellar scales are black, while in the 

 few specimens of S. cartroni sent the abdominal segments have narrow pale basal 

 bands, and the few remaining scutellar scales are white. 



Aedes (Ochlerotatus) nigeriensis, Theobald. 



Cuhx fowleri, d'Emmerez de Charmoy, Ann. Trop. Med. ii, p. 258 (1908). 



Mr. H. F. Carter informs me that he has examined a male of C. fowleri from 

 Mauritius, and established its identity with 0. nigeriensis, which was already sug- 

 gested by the author's allusion to the two pale spots on the sixth abdominal tergite 

 of the female. 



A female in the Paris Museum from Madagascar may be either this species or 

 O.fryeri, Theo.
