1915] Ludlow — ■••l Question of Synonomy 139 



their Article "Malaria in the Philippines" had referred to its con- 

 nection 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 christophersi = listom, but showed that whatever 

 else the synonomy 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 "/u- 

 nesta," that is, it is unquestionably christophersi. 



The synonomy of this species as given by Mr. Edwards, and 

 added to by myself and jMr. Banks is therefore — 



Anopheles {Myzomyia) christophersi Theobald — alboapicalis 

 Theobald, mangyana Banks, ftinesta Ludlow non Giles, flavirostris 

 Liudlow, 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 ludlmvi Theobald, Myzomyia indef- 

 inita Ludlow, Myzomyia parangensis Ludlow, and is therefore 

 nearly as confusing in the reduction of names as is the multiplica- 

 tion 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-compre- 

 hended. 



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

 ma,rked " M. rossi or indefinita?" "I think I mentioned to you my 

 conclusions on this subject but am not sure. They are that indef- 

 inita is a variety of rossi representing it in the Philippines and 

 Malaya, the true rossi not occurring further east than India and 

 Ceylon. These specimens, like all I have seen from the Philip- 

 pines, are indejinita." 



Christophers^ says that though N. ludlowi rather closely 

 resembles Nsm. rossi the "eggs of the two species are quite dis-
