rather irregular patches on each side on the front half. Sciitellum pale, with narrow 

 pale golden scales. Pleurae with four or five small patches of pale ochreous flat 

 scales. Abdomen dark brown, tergites with white basal lateral patches and ochreous 

 basal bands, which are broadest in the middle ; sternites with dark apical bands. 

 Legs black ; all the femora black to the base above, ochreous beneath on the basal 

 half. Femora and tibiae all with conspicuous whitish tips, no scattered pale scales. 

 Tarsal joints conspicuously ringed with ochreous at the base only ; the rings on the 

 last two joints very narrow. Claws simple ; empodia large, nearly as long as the 

 claws. Wings with brown scales, those in the lateral series linear. First fork-cell 

 more than twice as long as its stem, its base nearer the base of the wing than that 

 of the second. Cross- veins separated by rather more than the length of the posterior.. 



Length, 6 mm.

Type in the Paris Museum ; paratype in the British Museum. 



This species is noteworthy for the ornamentation of the head, the basally ringed 

 tarsal joints, and the large empodia. It has no near ally among the described African 

 and Oriental species, and in the absence of the male it is impossible to say in what 

 subgenus it should be placed. Possibly it may be a Lutzia. 



Culexannulitarsis, Macquart. 



The brief description of Macquart will not apply to any known species. It was- 

 referred by Theobald to the synonymy of Stegomyiafasciata, but Macquart's descrip- 

 tion of the legs (hind tibiae with a broad white ring before the tip ; hind metatarsi 

 white, with a narrow black ring) makes the reason for this far from obvious. 



Culex (Lutzia) tigripes. Grandpre & Charmoy. 

 Tamatave (Jaillet). Described from Mauritius. 



Culex (Culex) quasigelidus, Theobald. 



Pseudoheptaphlebomyia madagascariensis, Ventrillon. 



This synonymy, previously given by me, can be confirmed from an examination 

 of the types, although Ventrillon's description does not agree. Additional specimens- 

 are from Ambohipomana {Bouet, 1905) and Tananarive {Waterlot, 1916). 



Culex (Culex) giganteus, Ventrillon. 



Cidex giganteus, Ventrillon, Bull. Mus. Paris, xii, p. 100 (1906). 



Culex neireti, Ventrillon, Bull. Mus. Paris, xii, p. 103 (1906). 



The original description of C. giganteus and C. neireti are very similar, except as 

 regards the size given and the markings of the "thorax. Study of the types shows 

 that the insects are actually the same, the differences in the description being due ta 

 inaccurate observation. In particular, Ventrillon's measurement of 10 mm. 

 body length for C. giganteus is a considerable exaggeration, the actual length being^ 

 only about 6 mm., excluding the proboscis. Additional specimens are from 

 Ambatofanghera and Ambohipomana (Bouet, 1905). 



The species is a close ally of the African C. annulioris, Theo., differing chiefly in 

 the greater extension of the yellow markings of the abdomen ; and in some small 

 details of the structure of the male hypopygium, notably the shorter and stouter
