ochraceous bands basally. Legs unbanded, femora and coxae oehreous, 
the former dark at the apex and above, tibiae and tarsi dark violet; the 
first two tarsi dimly oehreous at the base; hind tibiae one-third longer 
than the metatarsi. First sub-marginal cell scarcely longer and con¬ 
siderably narrower than the second posterior cell; the basal joint of the 
brown antennae is dull red-brown, with yellow scales; proboscis and 
palpi deep black. Halteres oehreous.”

(Dipt. Exot. 4th Supp. p. 9.) 
Proboscis, face, palpi and frons black (mesothorax brown, 
pale ochraceous in front of the scutellum; scutellum pale 
ochraceous brown, the lateral lobes dark); metathorax of a pale 
yellow (in the old specimens dull ochraceous); abdomen brownish- 
black, with white incisions, which, however, are often but little 
distinct (when denuded, as in the specimens now, the abdomen 
is yellowish-brown). Legs pale yellow. Wings clear, with the 
base and external border yellowish (veins all yellowish; first 
sub-marginal cell decidedly longer but very little narrower than 
the second posterior cell, its base considerably nearer the base of 
the wing than that of the second posterior cell, its stem short, 
only about one-fourth the length of the cell, base of the cell level 
with the junction of the sub-costal and costal; stem of the 
posterior cell equal to about two-thirds the length of the cell; 
posterior cross-vein not quite its own length distant from the mid 
cross-vein, sloping towards the base of the wing ; second long vein 
forming a distinct-angle with the marginal transverse). 
Length. —3 mm. (Macquart says 1^ lines). 
Habitat. —Egypt, from M. Bigot.

in Bigot’s collection, now in Mr. Verrall’s possession. It is a

I have seen, and cannot be confused with C. pipiens. The types
