A Monograph of Culicidae. 
sub-marginal; stem of the first sub-marginal a little the longer, 
but not so long as the cell; stem of the second posterior short, 
not quite so long as the cell. Cross-veins faint, posterior nearly 
twice its own length distant from the mid. Scales all rather 
broad and flat. Halteres yellow, with a few dusky scales on 
the knob. 
Length. —5 mm. 
Habitat. —Straits Settlements, Perak (Wray (22. *11. and 
21. 12. 1899); Selangor (A. L. Butler) (28. 10. 1899) ; Formosa 
(C. Ford) (8. 1. 1900). 
Time of capture. —In Formosa, June (Ford). 
Observations. —The female is a very distinct and beautiful 
form, yellow in colour, with purple thoracic spots and bands on 
the abdomen and with banded legs, differing from T. accr , 
Walker, from Queensland in many respects. 
Specimens have been also sent by Mr. Butler from Klang 
Forest, Selangor, where it is fairly common. Although there is 
a difference in size, I feel sure this is Frauenfeld’s Gulex conopas. 
I have seen one or two specimens which, not being in good 
condition, answer exactly to his description, appended below. 
Frauenfeld described the species from a 9 taken on board ship 
in the China Seas. It occurs right up the Malay Peninsula as 
far as Burma, and probably extends over China. A specimen 
in Bigot’s collection under the name C. flavidus is undoubtedly 
this species, but I am not aware that Bigot described it. Some 
poor specimens, much eaten by mites, received from Formosa 
evidently belong to this species. 
Description of C. conopas , Frauenfeld :— 
“ Impure ocliraceous, the dorsum somewhat darker; thorax somewhat 
lighter behind and at the sides; eyes black. Antennae, palpi, and 
proboscis yellowish, the latter brown for its apical third; palpi also brown 
at the tip, and appear in some lights glistening brown ; flagellar joints of 
the antennae with one or two bristles. Legs ochreous, with a silvery 
lustre in certain lights; tarsal joints somewhat darker with white rings. 
Wings limpid, ferruginous on the anterior border; all the veins and the 
fringe brown scaled. 
Length. — 3 mm. ( ? ).”
