CULEX SECUTOR 283 



Original Desckiption of Cxjlex secutob: 



Head deep brown, with creamy grey scales in the middle, darker round the edge, 

 and upright forked scales projecting out laterally; thorax deep brown, covered with 

 pale golden-brown scales, with two prominent bare lines in the middle in front, 

 slight expanding anteriorly. Abdomen almost black, with traces of white basal band- 

 ing. Legs deep brown, the anterior and middle unhanded, the posterior with apical 

 and basal banding. 



$. Head deep brown, with narrow curved dull golden-brown scales in the middle, 

 and with deep brown upright forked scales projecting outwards around the paler 

 scaled area; proboscis and clypeus black; palpi covered with deep brown scales, with 

 a small dull basal grey band to the long apical joint and a few gray scales scattered 

 about; antennae deep brown, with narrow grey bands. 



Thorax deep brown almost black, covered with small narrow curved golden-brown 

 scales, in front of the mesonotum are two parallel bare lines which expand a little 

 in front; there is a median double row of black bristles and also lateral rows; 

 scutellum deep brown in the middle, testaceous at the sides, with narrow curved 

 pale golden-brown scales and six nearly black median bristles; metanotum deep 

 blackish-brown; pleurte brown, with a few small patches of grey scales. 



Abdomen black, with black scales, showing violet reflections, the third and fourth 

 segments showing narrow dull white basal bands, the others with traces of dull 

 white basal spots, moderately hairy. 



Legs deep brown, fore and mid unhanded, hind banded, the bands involving both 

 sides of the joints; in the fore and mid legs there is a white knee spot and at the 

 apices of the tibiae are a few white scales and testaceous hairs; ungues of the fore 

 and mid legs equal, simple, curved; in the hind legs the metatarsi and all the tarsal 

 joints are apically and basally pale banded; ungues small, equal and simple. 



Wings covered along the veins with deep brown typical Culex scales; fork-cells 

 rather short, the first sub-marginal a little longer, but no narrower than the second 

 posterior cell; its stem equal to rather more than one-third of the length of the cell, 

 its base a little nearer the base of the wing than that of the latter; stem of the 

 second cell about two-thirds the length of the cell; posterior cross-vein nearly three 

 times its own length distant from the mid cross-vein. Halteres with a fuscous and 

 grey stem and pale ochraceous knob. 



Length. 4 mm. 



J". Palpi deep brown, the penultimate joint with a small spot at the base of a pure 

 snowy white, the two apical joints are about equal, rather long and with black hair- 

 tufts, the long antepenultimate joint has a narrow pale ring basally and is hairy at 

 the apex, ground colour ochraceous, which when the palpi are denuded in parts give 

 them a pale banded appearance; antenuEe banded dark brown and grey, plume-hairs 

 deep brown; proboscis deep bi'own, with a narrow pale band on the apical half. 



Thorax as in the $; abdomen with the second segment mostly grey scaled and the 

 other segments more distinctly banded and with more distinct lateral spots, densely 

 hairy with golden-brown hairs. 



Fore and mid legs with small apical banding, hind with the banding as in the $, 

 the last tarsal joint rather pale; fore and mid ungues unequal, the larger one uni- 

 serrated, the hind equal and simple. 



Length. 4 to 4.5 mm. 



Habitat. Jamaica (Grabham) (111). 



Observations. Described from two $'s and two (^'s sent by Dr. Grabham. The 

 specimens were bred from larvfe sent by Mr. Harris from Cinchona, 4900 feet. " I 

 have also caught it," says Dr. Grabham, " in Kingston, where it is especially abun- 

 dant after the heavy autumnal rains, also an energetic bloodsucker. The insects 

 follow one about in a regular cloud." 



Dr. Grabham also sends the larvae and pupae. 



It is a very distinct species which can at once be told by the thoracic ornamenta- 

 tion and the peculiar banding on the legs. 



Original Description of Culex quasisecutor: 



Thorax deep brown with small dull golden-brown scales, collected into two paler 

 spots, with a somewhat pale scaled line extending backwards from them, and traces 

 of pale scales in front over the head, two median short basal lines as in secutor. 

 Abdomen deep brown, with basal pale bands. Legs deep brown with prominent 

 apical and basal pale banding to the hind legs, just traces of it on the fore and mid 

 legs. Proboscis unhanded in the female, banded in the male. 



$. Head deep brown with pale grey narrow-curved scales in the middle with 

 creamy reflections, duller at the sides, but smaller and brighter around the eyes, 

 lateral area with flat creamy scales, numerous black upright forked scales espe-
