NOTES ON PHLEBOTOMUS, WITH DESCRIPTIONS OF 

 NEW SPECIES— PART I. 



By Professor R. Newstead, F.R.S., 



The Liverpool School of Tropical Medicine. 



In making a critical examination of the palpi of the various species of Thle- 

 botomus described in this paper, I have found that the third* segment of the 

 palpi in all of them is provided with a compound group of minute and curiously 

 modified spines. In P. minutus (fig. \c) they are somewhat squamiform and the

 c, modified spines ; d, a similar spine from palpus of P.papatasii, Scop. ; e, palpus of P. minutus 

 var. africanus, Newst., $ , dorsal view ; /, basal segments of the same, lateral view ; g, modified 

 spines ; h, palpus of P. squamlpleuris, Newst., $ ; i, modified spines ; 7c, mosquito-likft scales on 

 pleurae of P. squamlpleuris. 



* In P. squamlpleuris they occur on the second segment also ; but I find no trace of them on 

 the corresponding segments in the other species. R.N.
