valuable weapon in the liauds of the practical sanitarian in 

 troi)ical countries. Very often the adult Anoioheles is difficult 

 to find and if the larvae are transported to a distance they fre- 

 quently do not develop, and thus very desirable information is 

 lost. By breeding out larvae of Anopheles from the eggs of 

 known species in the Malay Peninsula it was possible to follow 

 their various changes up to maturity. The following species 

 were those studied: — -4. alhirostris, Theo., A. sinensis, "\Vied., ^4. 

 fnliginosus, Giles, A. karicari, -James (= nigrans, Stanton), A. 

 umbrosus, Theo., A. rossi, Giles, and A. ludlowi, Theo. The 

 author has selected A. alhirostris, Theo., one of the malaria- 

 carrying species of the Malay Peninsula, for description. 



Save in the case of a few closely-related species, of which 

 rossi and ludloivi, sinensis and barbirostris are examples, the 

 mature forms of larvae of Malayan Anojjheles have been found to 

 possess characteristic features which permit of their specific 

 differentiation. So far, only the anterior and posterior clypeal 

 and the palmate hairs have been studied in detail, and it is hoped 

 that further study will reveal points of difference which will 

 lender possible the recognition of the matiire forms of all valid 

 si)ecies. It may well be that the distinctive characters which 

 may be observed in these developmental stages will form the 

 basis for a more satisfactory grouping of adult Anopheles than 

 that Avhicli has been founded upon scale characters alone.
