222 F. W. EDWARDS — NEW SYNONYMY 



Ceylon the .synonymy is in the highest degree probable. Stanton has recently 

 stated (J. Lond. Sch. Trop. Med., ii, 1912, p. 6) that James and Liston's 

 Nyssomyzomyia punctulata is also the same as A. tessellatus. 



2. Anopheles kochi, Donitz. 



Anopheles koc hi, Donitz, Insecten-Borse, xviii, p. 1 (1901). 

 Celliaflava, Ludlow, Can. Ent. xl, p. 32 (1908). 

 Specimens named by Dr. Ludlow have recently been received, and on com- 

 parison with the British Museum series proved to be normal A. kochi. James' 

 Christopher sia halli is already recognised as a synonym of this species. 



2a. Anopheles christophersi, Theo. 



Anopheles christophersi, Theo., Proc. R. Soc. lxix, p. 378 (1902). 



Myzomyia mangy ana, Banks, Phil. J. Sci. i, p. 991 (1906). 



Myzomyia funesta, Ludlow {nee Giles), Can. Ent. xxxvii, p. 135 (1905). 

 Theobald described the female palpi of A. christophersi, as having " two broad 

 apical white bands and a narrow one near the base," and an examination of the 

 type shows that this is perfectly correct, and that the species is quite distinct 

 from A. listoni, Liston ; on the other hand it is evidently the same as M. mangy- 

 ana, Banks, which is represented in the British Museum by a female cotype. I 

 have recently had an opportunity of examining some specimens from the 

 Philippine Islands named Myzomyia funesta by Miss Ludlow. These are in 

 reality A. christophersi, and it may therefore be presumed that A. funestus is not 

 known from that region. 



Tribe 2. Megarhinini.

Mon. Cul. i, p. 244 (1901). 



3. Toxorhynchites immisericors, Walk. 



Megarhinus immisericors, Walker, Proc. Linn. Soc. London, iv, p. 90 

 (I860). 



Megarhinus gilesi, Theo., Mon. Cul. i, p. 227 (1901). 



Toxorhynchites ar g ent eot arsis, Ludlow, Can. Ent. xxxviii, p. 367 (1906). 



Worcesieria grata, Banks, Phil. J. Sci., i, p. 779 (1906). 



(?) Megarhinus subulifer,Do\., Nat. Tijd. Ned. Ind. xiv, p. 382 (1857). 

 This is a variable species, but the variation seems to me to be quite continuous ; 

 it is noticeable chiefly in the amount of white on the mid tarsi of the female and 

 in the markings of the underside of the abdomen. The cross- veins also are very 

 variable. There is no evidence to show that the palpal differences given by 

 Theobald between immisericors and gilesi are really specific, nor can any other 

 constant difference between them be discovered. I have not examined a specimen 

 of T. argenteotarsis, but the description is quite full enough to warrant the 

 assumption that it is only a form of T. immisericors. A male of W. grata, 

 named by Banks, is in the British Museum, and I have therefore been able to
