situations, but this is not always exhibited. Very dirty breeding- 

 places seem to be avoided. Very few data were collected regarding 

 A. albotaeniatus and no conclusions could be reached regarding it. 

 A. leucosphjrus is a very local species ; some shade appears to be 

 sought for, but no other special preference was detected. 



Froi'\^ the above data the following conclusions are obtained. 

 Specific sanitation (on the lines known at present) is not adapted for 

 combating Anophelines of the liills, ubiquitous, or shade-preferring 

 species, because they have no speciahsed demands regarding .their 

 breeding-places and the destruction of these would interfere too much 

 with economic hfe. General sanitation, i.e., the destruction of all 

 actual and potential breeding places of all Anophehnes, appears at 

 present to be the only means that can be recommended. In view 

 of its special breeding-places and also on acccount of its dangerous 

 character, A. ludlowi might be the subject of special measures such 

 as the destruction of its salt-water breeding-places. This should, 

 however, be done as an experiment.

Up to recent years there has been no Dutch terminology for des- 

 cribing Anopheline larvae. The author and Dr. Schiiffner have used 

 a number of terms, and as Dr. Mangkoe Winoto has published a paper 

 [R.A.E., B, vii, 76] with a different terminology, it is thought advisable 

 to show the differences in a table. The author adds that Schiiifner 

 and himself have always taken full-grown larvae for description and 

 that in the case of unknown larvae it is necessary to breed the adult 

 before attempting to determine the species.

This paper is intended to complete two previous ones by Schiiffner 

 and Swellengrebel {Geneesk. Tijdschr. Nederl.-Indie, 1914), and by 

 Schiiffner and van der Hey den [R.A.E., B, v, 27], describing the 

 Anophehnes occurring in the Dutch East Indies and to furnish a 

 key which includes the species recently recorded. 



The following notes refer to some of the species dealt with. Anopheles 

 {Myzorhynchus) argyropus, Swell., must be regarded as a synonym 

 of A. mauritianus, Gr. A. sinensis, Wied., embraces many species, 

 and some or all of them may be reinstated as a result of investigation ; 

 for the present they must remain under the above name. A. aconitus, 

 Don., is a variety of A. minimus, Theo., A. {Neomyzomyia) punctu- 

 latus, Don., is a synonym of A. {N.) tessellatiis, Theo. ; A. {Myzomyid) 

 indefinitus, Ludl., is no longer considered a variety of A. rossi, Giles. 

 A. ludlowi has more claim to be treated as a variety of A. rossi, but 

 it is however better to treat it also as distinct species. A. rossi,
