the snow-white hind tarsus distinguishing it from all other Malayai 
anopheles. Since writing, Dr. Watson, of Klang, has sent me a mosquitc 
which I have named “ Pyretopliovus Watsonii ,” after him. This mosquito hai 
the last three tarsal joints creamy. This is the only other Malayan ano 
pheline with a white hind tarsus, but is easily distinguished from Xivipe: 
by the spotted femora and tibiae the golden thoracic sealing, etc. 
Genus 7. —Cellia. 
Thorax, with fusiform scales ; abdomen more or less covered with lon£ 
narrow-curved or fusiform scales irregularly disposed and with densi 
lateral tufts ; wing scales large, bluntly lanceolate. 
Remarks .—One species of this genus occurs in Malaya and it is failD 
common and widely distributed. The marked feature of the genus is th< 
lateral scale tufts. This character enables the members of this genus to b< 
at once distinguished from those belonging to Nyssorhyncus. In othe 
respects the members of these genera are not unlike.

in some specimens, an incomplete black band at the base of the labellae. 
Thorax .—Prothoracic lobes black, clad with golden scales. Mesonotum 
pale yellowish-brown with a silvery frosting on either side, and about ; 
third of the total length from the anterior margin is a dark brown eye-lik<
