J. W. SCOTT MACFIE AND A. INGRAM. 



This larva seemingly should be grouped with that of C. duftoni in Edwards' key 

 (Bull. Ent. Res. iii, p. 379). It may be distinguished from the larva of C. duttoni 

 by its possessing marked tufts of hairs on the siphon in place of long solitary hairs, 

 and by the number of teeth in the pecten.

Pupa. — ^There does not appear to be any distinctive feature about the pupa when 

 examined with a low magnification (60 diameters). 



Breeding place. — The larvae, together with those of Eretmopodites inornatus, were 

 found in water of a dark brown colour containing decaying leaves and vegetable matter, 

 filling a hollow in the concrete foundation for the erection of a pump.
