LIST OF THE ANOPHELINES OF THE MALAY ARCHIPELAGO WITH 

 SPECIAL REFERENCE TO ADULTS AND LARVAE OF NEW OR 



INCOMPLETELY DESCRIBED SPECIES OR VARIETIES. 

 By N. H. SwELLENGREBEL, Ph.D. and J. M. H. Swellengrebel de Graaf. 



The following species and vaneties have been found in the Malay Archipelago* : — 



Myzomyia : ludlowi, rossii, vaga (indefinita), flava, minima, minima var. aconita, 



Neomyzomyia : leucosphyra., punctulata var. tesselata. 



Cellia : kochi. 



Myzcyrhynchus : sinensis, sinensis var. vanus and var. separatus, barbiiostris, 

 barbirostris var. palhdus, albotaeniatus, mauritianus, umbrosus, gigas. 



Nyssorhynchus : fuhginosus,. maculatus, schiiffneri, karwari, jamesi, annulipes 

 var. moluccensis. 



Stethomyia : aitkenii, aitkenii var. insulae-florum and var. papuae. 



Comparison with the neighbouring Malay Peninsula shows the Anopheline 

 fauna to be almost identical in the two countries. The exceptions are : — 

 M, aurirostris, P. watsoni, M. sinensis var. peditaeniatus, M. albotaeniatus var. 

 montanus, M. pseudumbrosus, M. hunieri and L. asiatica, which are not found 

 in the Archipelago ; whereas the Peninsula lacks M. mauritianus, M. yigas, 

 M. barbirostris var. pallidus, S. aitkenii var. insulae-florum and var. papuae, and 

 N. annulipes var. moluccensis. 



I. — Description of New Species and Varieties. 



1. Myzomyia immaculata, Theo. 



Myzomyia flava, SvveUengrebel (1917). f 



A yellow mosquito, with hght orange- coloured unhanded legs, creamy unhanded 

 palpi, browTiish yeUow proboscis and creamy wing scales. Wings unspotted. 



$. Head scaled like M. rossii, on the occiput broadly expanding upright forked 

 scales, all scales creamy. Palpi unhanded, creamy. Proboscis brownish yellow, 

 labella yeUow. Thorax : prothoracic lobes with brownish yellow hairs. Mesonotum 

 with hair-hke scales, narrow curved ones in front and a few at the sides, all scales 

 creamy. Scutellum with dark yellow hairs and creamy hair-like scales. Haltered 



* Contrary to tlie present custom we adhere (with a few exceptions) to Theobald's 

 nomenclature, not because we attach to his ''genera" any intrinsic value as indicating 

 a really existing relationship, but because the division of the Anophelines into genera 

 is a practical measure, expre-ssing the idea present in the mind of every one who studies 

 these insects in nature, that, e.g., M. sinensis is quite distinct from M. aoonita, but closely 

 allied to 31. barbirostris, and that >Si. aitkenii is something apart from all other Anophelines. 

 By calling all these species " Anopheles " one simply causes confusion and not sim])lirica- 

 tion. 



I [On a recent visit to England Dr. Swellengrebel presented to the British Museum a 

 (^ and $ of his Myzomyia jiav a. On comparing the latter with the type of Theobald's 

 A. immaculatus both he and Mr. F. W- Edwards concluded that they were consi^ecific. 

 The older name immaculatus must therefore be used for this interesting and little 

 known form. — Ed.]
