CULEX SUBFUSCTJ8 429 



Obiginal Description of Culex nigbipai-pus : 



Head grey; thorax chestnut-brown; abdomen almost black, unbanded, grey ven- 

 trally; proboscis almost black; palpl longer than proboscis, black, last two joints 

 with black hairs, acuminate; legs dark brown, unbanded. 



£?. Head dark brown, the middle clothed with very small narrow golden curved 

 scales, the sides with flat greyish scales, which extend some way each side on to the 

 occiput; there are also numerous small black upright forked scales on the back of 

 the mid area down to the nape; antennae brown, with grey bands and dark brown 

 to almost black plumes; proboscis black, testaceous at the apex; palpi longer than 

 the proboscis by nearly the whole of the last two joints, there are traces of a pale 

 band near the base of the antepenultimate joint, the penultimate joint a little longer 

 than the apical joint, minutely testaceous at the base, apical joint acuminate; the 

 last two joints with stiff black hairs, and the apex of the antepenultimate with two 

 thick bristles. 



Thorax deep clear chestnut brown, with very small narrow curved dull fawn- 

 coloured scales and with black bristles, especially long over the roots of the wings; 

 scutellum pale ochraceous to greyish-brown with small curved pale dull brown scales 

 and long brown border-bristles, six in number to the mid lobe; metanotum brown; 

 pleurae pale brown. 



Abdomen covered with deep brown scales dorsally, with violet reflections, venter 

 pale, covered with grey scales; on the last segment are some grey scales also dorsal; 

 genitalia ochraceous; border-bristles rather pale. 



Legs dark brown, the femora grayish beneath; fore ungues unequal, rather 

 straight, the larger one uniserrated, the smaller (apparently) simple; mid ungues 

 unequal, very similar to the fore; hind ones minute, equal, and simple. 



"Wings with brown scales, the median ones rather thick and short and dense, 

 especially on the fork-cells, but also with longish, nearly straight lateral scales, the 

 scales on the sub-costal and first long vein darker and very dense, those forming the 

 upper border of the wing black and lanceolate; the first sub-marginal cell a little 

 longer and narrower than the second posterior cell, its base nearer the base of the 

 wing than that of the latter, its stem equal to about one-fourth of the length of the 

 cell, considerably shorter than that of the second posterior cell, which is equal to 

 about two-thirds of the length of the cell; posterior cross-vein more than twice its 

 own length distant from the mid cross-vein; fringe dark brown. 



Length. — 2.5 mm. 



Habitat. — St. Lucia (Dr. Low). 



Observations. — Described from a single ^ in perfect condition. It can at once be 

 told by the dark pointed palpl and unbanded abdomen from any other of the related 

 species. The head ornamentation is very peculiar and marked. The lateral fiat 

 grey scales show very clearly against the brown thorax. No note of any kind sent 

 with the specimen. 



We have not recognized this species in the material before us. 



The larva is unknown. According to Theobald Dr. Low bred the adults from 

 larvEe found in a pool, where they were associated with the larvae of Uranotaenia 

 lowii and Anopheles. 



Lesser Antilles. 



Island of Santa Lucia, West Indies (Theobald). 



Theobald later recorded a single male from the island of Barbados, but we are 

 inclined to doubt the identification.

 proboscis with a pale band. Thorax rich brown, unadorned; scutellum paler. Abdo- 

 men deep brown, with basal pale bands. Legs deep brown, with very narrow apical

/? Head deep brown, with scanty narrow-curved pale creamy scales and brown 

 upright forked scales, sides with flat creamy scales. Palpi deep brown, the apical 

 segment longer than the penultimate, both with lateral deep brown (flaxen in some
