 a most inoffensive mosquito. Although breeding in myriads in all roadside puddles 

 it seems not to bite and does not enter houses. The adults were all named " Gulex 

 secutor Theob." by Mr. Coquillett, except one of Mr. Busck's, which was called 

 "pipiens" (it may have been in bad condition). To the junior author's specimens 

 he added a query and the note " also janitor? and tarsalisf "

Description or Femaue, Male, and Labva of Citlssk coeonatoe: 



Female. — Proboscis rather long, subcylindrieal, uniform, labellae conically 

 tapered, pale ; brownish black, darker at tip, a long white stripe on under side 

 near middle; setae minute, curved, black, those on labellae more prominently 

 outstanding. Palpi short, one-fifth as long as proboscis, slender, black, with a 

 few outstanding setae. Antennae with the joints subequaJ, rugose, pilose, black ; 

 tori subspherical, with a cup-shaped apical excavation, luteous, black on inner 

 side; hairs of whorls sparse, moderate, black. Clypeus rounded triangular, 

 doubly excavated at base, prominent, brown, nude. Eyes bronzy black. Occiput 

 blackish, clothed with narrow, curved pale-brown and brassy scales on vertex, 

 becoming whitish at lower parts of sides and along margins of eyes, many erect, 

 forked scales behind, mostly pale, a few of the central ones black and forming a 

 patch on each side ; black bristles along margins of eyes. 



Prothoracie lobes elliptical, remote dorsally, brown, clothed with small pale 

 scales and black bristles. Mesonotum brown, with two dorsal impressed lines 

 of the same color ; vestiture of narrow, curved bronzy-brown scales, scales around 

 margins and ante-scutellar space paler, yellowish ; a pair of pale subdorsal spots 

 on the disks, and rather numerous black bristles ; scutellum trilobate, pale brown, 

 clothed with narrow, curved, pale scales, each lobe with a tuft of brown bristles. 

 Postnotum elliptical, prominent, luteous, nude. Pleurae and coxae greenish 

 luteous, with small patches of elliptical white scales and rows of brown bristles. 



Abdomen subcylindrieal, depressed, truncated posteriorly; dorsal vestiture 

 brownish black, a distinct rather narrow white band at the base of each segment 

 except the first and a row of pale hairs at apex, on the sides the bands widen into 

 triangular spots ; venter yellowish-white scaled. 



Wings moderate, hyaline; stem of second marginal cell about one-fifth as 

 long as its cell, that of second posterior much shorter than its cell ; basal cross- 

 vein distant more than its own length from anterior cross- vein; scales brown, 

 the outstanding ones long, broadly linear, denser apically. Halteres pale. 



Legs moderate, femora white beneath nearly to tip ; tibiae brownish black, pale 

 below, tarsi darker; knees, apices of tibiae and a ring at tip and base of each 

 tarsal joint, white, much narrower and mostly basal on fore and mid legs, 

 on hind tarsi broader, and with the last joint white with black middle ring. 

 Claw formula, O.O-O.O.-O.O. 



Length : Body about 4.5 mm. ; wing 4.5 mm. 



Male. — Proboscis straight, slightly thickened towards apex, black scaled, 

 with a broad pale ring beyond middle. Palpi exceeding the proboscis by nearly 

 the length of the last two joints; end of long joint and the last two joints with 

 long, dense, black hairs, whitish ringed at bases of last two joints, a small white
