586 A Monograph of Culicidae. 



towards the centre, somewhat shiny and metallic ; venter pale 

 creamy yellow. 



Legs brown with metallic reflections ; tibiae with spine ; fore 

 ungues very slightly unequal, simple, also the mid. 



Wings with long fork-cells, the first sub-marginal longer and 

 narrower than the second posterior cell, its stem less than one- 

 half the length of the cell ; stem of the second posterior about 

 two-thirds the length of the cell, base of the first sub-marginal 

 cell slightly nearer the base of the wing than that of the second 

 posterior ; posterior cross-vein longer than the mid, very slightly 

 nearer the base ; scales as in the } . 



Length — 6*5 mm. 



Habitat. — Mana, Brazil (Dr. Fajardo). 



Time of capture. — April. 



Observations. — Described from a perfect $ sent with a ? . 

 The male has not previously been described. 



Previous specimens have been sent (Yol. III.) from British 

 Guiana. The frontal process of the $ is not so pronounced as 

 in the J . 



Genus HYLOCONOPS. Lutz. 



Mosquitos do Brasil, pp. 49 and 55 (1904). 



Head with flat scales ; proboscis swollen at the apex, not 

 longer than the body ; palpi short in the J , as long as the 

 proboscis in the $ ; antennae plumose in $ ; pilose in 9 . 



Thorax with long narrow-curved scales over most of the 

 surface, with a large lateral patch in front of closely appressed 

 flat scales, and some irregularly placed larger flat scales just in 

 front of the scutellum, which is clothed with flat spatulate scales ; 

 pleurae completely clothed with closely appressed small flat scales ; 

 metanotum with chaetae and squamae. Wings with rather large 

 scales. 



This genus has, like Trichoprosopon, the curious patch of flat 

 closely appressed scales on each side of the thorax in front and 

 the densely armoured pleurae. It seems to me to resemble it 

 very closely, but the swollen apex of the proboscis and the 

 shorter $ palpi will separate it. In any case it is very close to 

 Trichoprosopon. Lutz describes one species, Hyloconops pallidi- 

 venter, and has given me another, which he called longipalpis, 

 and a third he sent me in a previous lot.
