one hand, and the group Anopheles, Myzomj^a, and 

 Pyretophorus on the other, for in the species Stephen si 

 (voL iii, p. 93) the abdomen is described as covered with 

 scales, while maculipalpis (vol. iii, p. 97) is credited with 

 a very few scales on the apical segment only (apparently a 

 characteristic also of My z orhynchus), while in pre tori - 

 en sis we can detect but some seven or eight in all on the last 

 segment. On page 111, vol. iii, albipes is called both 

 Cellia and Ny ssorhynchus. 



The shape of wing scales, as desci-ibed, might be thought 

 sufficiently to distinguish the latter from Myzomyia, bur, 

 Theobald expresses doubt as to whether the species elegans 

 is not of the genus Ny ssorhynchus rather than of 

 Myzomyia, to which he has allotted it, and says that it is 

 very near to stephensi,a species of which the abdomen is 

 thickly scaled (vol. iii, p. 53). Again, the descriptive slip on 

 Plate V in the same volume indicates that pretoriensis 

 barely escaped from the genus Pyretophorus. 



From the table in ' Monograph of the Anopheles Mosquitoes 

 of India,^ and from illustrations and descriptions in ' Mono- 

 graph of the Culicidas of the World,^ a table of larval 

 characteristics has been compiled to which are added in their 

 place the nine species identified by us :
