etc., make their appearance in such a mosquito well, and if one 
wishes to encourage mosquitoes to breed in it, it is necessary to 
clean it out occasionally. 
I have also bred it out from mixed larvae obtained from the 
Kedron Brook, in the vicinity of Alderley. 
Mosquitoes have a hard existence in permanent water 
courses, as these are stocked with small fish, and a large variety 
of insects ; their safest position is at the extreme edge, where 
the water is an inch or less deep. 
The eggs and larvae have yet to be observed, and whether 
the mosquito bites ; hitherto only a few specimens have been 
obtained, and all have been pinned for identification. 
PYRETOPHORUS.— Blanchard (1902).

Pyretophortts atratipes. — Skuse (1888). 
$ . Antennae about three -fourths the length of the palpi ; 
dark brown almost fuliginous, with hoary pubescence and 
verticils ; first joint of the scapus black. Head fuliginous, 
adorned with white scales, intermixed with some black hairs, 
and a tuft of long whits parallel hairs stretching out from the 
vertex over the bases of the antennae. Proboscis and palpi 
densely and uniformly clothed with deep violet-black scales, 
the terminal joint of the latter very slightly tipped with white. 
Thorax primrose-brown, with a small roundish black spot laterally 
about the middle of its length, and another immediately in front 
of the scutellum, traversed by three long, parallel double rows 
of moderately long black hairs intermixed with short slender 
shining white scales ; lateral margins slightly testaceous with a 
few scattered white scales and some short white hairs above 
and in front of the origin of the wings ; pleurae dark brown, 
somewhat marbled with testaceous ; scutellum testaceous, with 
a dark roundish spot on the apex, fringed with long black hairs, 
metanotum brown, halteres black, or very deep brown, the stem 
ochre-yellow. Abdomen about twice length of thorax, black, 
levigate, sparsely clothed with golden-yellow hairs (terminal 
joint more densely) ; lamellae of ovipositor black, fringed with 
short golden-yellow hairs. Coxae ochreous. Legs clothed with 
violet-black scales, femora and tibae bright ochreous beneath 
and very slightly at the tips. Coxae pale ochreous without scales, 
slightly hairy. Wings length of the entire body, bright ochre- 
yellow at base, hyaline, veins very densely covered with scales, 
those on the costa, auxiliary and first longitudinal veins black,
