PLAIN WINGED CULICES WITH BANDED PROBOSCIS 401 



species from Sumatra, and in similar instances of other species where 

 tire "type" is missing and tlie original description inadequate, is of 

 course more or less problematical ; and the form here described would 

 answer as well in fact to Walker's description of C. itnpellens, but it is 

 certainly better to follow this course than to make a new species, and 

 so leave the older names with a probably inerely nominal status. 



18. CULEX TRITiENIORHYNCHUS, Giles. 



(Journal Bombay Nat. Hist. Soc. xiii, p. 607.) 



Tarsi minutely basally banded pale ochreous. Thorax un- 

 adorned, fuscous. Abdomiual segments fuscous, with rather 

 narrow yellowish-white basal bands. Proboscis fuscous, with 

 three separate ochreous bands, one forming the tip ; the second, 

 sharply defined and much broader, beyond the middle ; the third 

 less sharply defined, especially iu the $ , and placed midway 

 between the large broad band and the base. Wing with the fork 

 of IV just inside that of II, and 4, but its own length internal 

 to 3 ; less than this in the S' • 



A mmute species, of generally dusky tinting, and with proportionately 

 long legs. Head fuscous ; eyes with a barely perceptible whitish margin ; 

 nape fuscous, with a few whitish hairs ; antennae fuscous, minutely 

 banded white in the ^ ; palpi of ^ , considerably longer than the pro- 

 boscis, exceeding it by more than the length of the markedly subulate 

 terminal joint, fuscous, with minute white basal bands to the last three 

 joints, ? , exceptionally mmute, nearly black, with an indistinct gi-eyish 

 tip. Halteres pale j^ellow. Legs fuscous, the tarsi with minute ochreous 

 basal bands to all the joints ; first hind tarsal longer than the correspond- 

 ing tibia in both sexes. Length. — Under 3 mm. 



Habitat. — Travancore, Southern India. 



19. CULEX CONFINIS (Arribal.) ("L. A." p. 49). 



Very like Tceniorlnjnclms tceniorhynclms , Arribiilzaga, but of smaller 

 size and darker colour, while the band on the proboscis is broader ; 

 but it differs generically in the form of the wing scales. The broad 

 white proboscis band extends from near the base to the middle. Legs 

 fuscous, fore femora sparsely decorated with scattered white scales, with 

 a narrow white band a little before the apex ; tibiae sjpeckled white 

 externally, uniformly coloured inside ; knees white ; fore and mid tarsi 

 with the first three, and the hinder with four, or all the joints, with basal 

 white bands ; first hind tarsals distinctly shorter than tibia;. Abdomen 

 dark fuscous, with coffee-coloured scales above and narrow whitish 

 apical bands ; greyish below. Length. — 4*5 to 5 mm. 



Habitat. — Chaco in Formosa, Argentina.
