CULEX PIPIENS 363 



Wings with the costa, first long vein, third and lower part of the fifth black, other 

 veins brown; first sub-marginal cell longer and narrower than the second posterior, 

 its base considerably nearer the base of the wing, its stem rather less than one-third 

 the length of the cell; stem of the second posterior more than half the length of the 

 cell; posterior cross-vein nearly twice its own length distant from the mid. Halteres 

 testaceous, with slightly fuscous knob. 



Length. — 4 mm. 



HaMtat. — St. Michaels, Azores (Dr. Grabham). 



Time of capture. — 22. 9. 02. 



Observations. — ^Very closely related to C. Aeoriensis. The abdomen has three or 

 four prominent pale basal bands, and there are no long curved scales in the middle 

 of the occiput. The venation is much as in 0. Azoriensis. Described from a series 

 taken by Dr. Grabham in the Azores. I am not certain of its male, so have not 

 described it. It is very close to C. fatigans, but I feel sure distinct; the last few 

 segments of apex never being banded. 



Obiginai, Description of Culex azokibusis: 



Thorax brown, with small narrow dull golden-brown scales and two median bare 

 parallel lines in front. Abdomen deep brown above, unhanded, with basal lateral 

 pale spots and pale venter. Legs deep brown, unhanded. Wings with the fork-cells 

 as in C. pipiens. Palpi and proboscis deep brown, unhanded. Head with long 

 narrow-curved golden scales forming a median line. 



?. Head brown, with curved dull pale golden-brown scales, with a broad line of 

 long paler ones in the middle, with numerous black, thin, upright forked scales and 

 small fiat grey ones at the sides; a slightly paler row of scales around the eyes; 

 palpi, proboscis and clypeus black; antennse deep brown, basal joint and base of the 

 second joint testaceous. Thorax deep brown, with small narrow-curved golden-brown 

 scales and showing two dark bare median parallel lines in front, slightly expanding 

 anteriorly, with black bristles, especially dense over the roots of the wings; scu- 

 tellum paler brown, with narrow curved pale scales and eight brown bristles to the 

 mid lobe; metanotum pale brown; pleurae pale brown and grey. Abdomen black, 

 unhanded, with golden border-bristles and now and then traces of a few pale scales 

 along the bases of the segments; there are also rather indistinct pale basal lateral 

 spots, the apical segment with many ochraceous scales; venter all pale creamy. Legs 

 deep brown, unhanded, venter of femora creamy-grey; knee spot faint; ungues small, 

 equal and simple. Wings with the first sub-marginal cell longer and narrower than 

 the second posterior cell, its base nearer the base of the wing than that of the latter; 

 its stem less than one-fourth the length of the cell; stem of the second posterior 

 rather more than half the length of the cell; posterior cross-vein about one and a 

 half times its length distant from the mid cross-vein. Halteres pale, with slightly 

 darker knob. 



Length. — i mm. 



c?. Palpi deep brown, with a narrow pale basal band ; last two joints and one side 

 of the apex of the antepenultimate joint with black hairs. Thorax, abdomen and 

 legs as in the $. Fork-cells of wings moderately long. Ungues of fore and mid legs 

 unequal; the larger uniserrated, the smaller (?). 



Length. — 4 mm. 



Habitat. — St. Michaels, Azores. 



Time of capture. — September. 



Observations. — Described from a series collected by Dr. Grabham. It comes very 

 near C. scholasticus, Theobald, from the West Indies, but the cJ palpi are hairy and 

 they are not in this species and the median long scales over the head again sepa- 

 rate it. 



It might also be mistaken for Ficalbi's G. modestus, but the abdomen has not 

 scanty yellowish speckling. 



Obiginai, Desceiption of CTiiiEX osAKAENSis (female only) : 



Thorax with dull golden yellow scales, brighter before the scutellum, with a 

 darker wedge-shaped area on each side in front of the wings and two indistinct 

 darker areas in front of them, the chaetae showing as two dark lines posteriorly 

 on the brighter scaled area; traces of two median parallel bare lines in front; head 

 slightly paler than the thorax. Abdomen deep brown with basal white bands. Legs 

 brown, unhanded. Palpi of ? with mottled brown and white scales. . . . 



$. Head deep brown clothed with narrow-curved creamy scales, dark-brown up- 

 right forked scales, flat creamy lateral ones few in number and with dark brown 

 chaetae surrounding the front of the head directed towards the middle of the head;
