156 C. S. LUDLOW. 



note explaining the error which had occurred, giving the correct name and synonymy, 

 which, with the description of flavirostris immediately following, it was believed 

 would make the matter quite clear. 



It was therefore a surprise to find Mr. Banks had redescribed this species as 

 A.febrifer* and that Messrs. Walker and Barber in their article "Malaria in the 

 Philippines " had referred to its connection with malaria as if that were quite 

 unknown.! The foot-note at the end of this article is also definitely misleading, 

 as I did not suggest that christopJiersi = listoni, but showed that, whatever else the 

 synonymy might be, it did not include listoni. 



Dr. Marshal A. Barber sent me specimens of this mosquito for determination 

 which reached me in beautiful condition, and there can be no doubt that it is the one 

 I had wrongly referred to "/z/ne^to," that is, it is unquestionably Christopher si. 



The synonymy of this species as given by Mr. EdwardsJ and added to by myself 

 and Mr. Banks is therefore :• — 



Anopheles (Myzomyia) Christopher si, Theobald. 

 = alboapicalis, Theobald. 

 = mangyana, Banks. 

 = funesta, Ludlow (non Giles). 

 = flavirostris, Ludlow. 

 = febrifer, Banks. 



The re-naming of this species by Banks is the more interesting because of the extreme 

 amount of malaria among the Mangyans and that Myzomyia mangyana, Banks, was 

 described in connection with a recognition of that condition. 



In regard to Anopheles rossi, Giles, as used by Banks, it includes at least three 

 forms : — 



Myzomyia ludlowi, Theo. 

 Myzomyia indefinita, Ludl. 

 Myzomyia parangensis, Ludl. 



and is therefore nearly as confusing in the reduction of names as is the multiphcation 

 of names in the species previously considered. It is easy to collect data concerning 

 the relationship of these species, which have probably been more or less mis- 

 comprehended. Mr. Edwards writes me, in regard to specimens I had sent him 

 marked " M. rossii or indefinita ? " : ''I think I mentioned to you my conclusions

% [Mr. F. W. Edwards has kindly supplied the following note on this species : — " Since 

 publishing my views on the synonymy of this species (Bull. Ent. Ees., iv, p. 222) I have 

 come to the conclusion that the oldest name for it is A. minimus, Theo. It is very common 

 at Hong-Kong, and there is no other Hong-Kong species which answers at all to Theobald's 

 description. The name christophersi must therefore be dropped ; this is fortunate as it 

 will avoid any confusion with listoni. The Malayan A. aconitus, Don. (= albirostris, 

 Theo.) is probably a geospraphical form of A. minbnus, differing only in having the apical 

 half of the proboscis pale on the upper as well as on the under side. This ditTerence 

 however appears to be constant." — Ed.]
