no MAJOR E. E. AUSTEN. 



From the foregoing species C. puripennis is distinguishable, inter alia, by the 

 coloration of the dorsum of the thorax ; by the second segment of the antenna being 

 smaller and paler and the following five segments somewhat more elongate ; and by 

 the course (angulate instead of rounded) followed by the distal extremity of the 

 third longitudinal vein. 



The species just described is also allied to the European C. albicans, Winn., from 

 which it may be distinguished owing to the front and middle femora and tibiae not 

 being conspicuously tipped with blackish brown or black, and also (if Winnertz's 

 figure— Linnaea Entomologica, vi, Taf. vi, fig. 35h (1852)— is to be rehed upon) by 

 the less abruptly turned up distal extremity of the third longitudinal vein. 



Culicoides tentorius, sp. n. (PI. iv, fig. 1). 



^. — Length (3 dried specimens), from anterior margin of thorax to posterior 

 extremity of abdomen, 1 -2 to 1 -4 mm. ; length of wing, 1 -5 to 1 -75 mm. ; greatest 

 breadth of wing, 0-6 mm. 



5. — Length (9 dried specimens), from anterior margin of thorax to posterior 

 extremity of abdomen, 1 to 1-5 mm. ; length of wing, 1-4 to 1-6 mm., greatest 

 breadth of wing, 0-75 mm. 



Dorsum of thorax {in dried specimens) cinnamon-drab {(^, and sometimes ?), or 

 cinnamon-coloured ($) ; dorsum of abdomen {in dried specimens) clove-brown or warm 

 sepia-coloured ; wings mouse-grey {^), or sepia-coloured or dtisky-drab ($), an obliquely 

 elongate area at base pale, otherwise in both sexes the only light markings are situate 

 on costal border in shape of a pair of conspicuous ivory-yellow spots, of which that nearer 

 the base is the larger (PI. iv, fig. 1) ; ground-colour of legs cream-buff or cinnamon-buff, 

 hind tibiae in both sexes jringed posteriorly imth a row of long hairs.

Head fawn-coloured (face cinnamon-buff), vertex infuscated (blackish-brown or 

 deep mouse-grey) in (^ and in both sexes clothed with curved, glistening, yellowish 

 hairs ; inner margins of upper lobes of eyes in $ very narrowly separated ; proboscis 

 and palpi cinnamon-buff in ,^, sepia-coloured or dark brown in $, palpi in $ clothed 

 with brownish hair, third segment moderately swollen towards distal extremity 

 (fig. 1) ; antennae in both sexes cream-buff or light cinnamon-buff (distal segments 

 sometimes darker), fourth to tenth segments in $ moderately elongate (fig. 2), hair 

 on antennae, including antennal plume in 1^, glistening yellowish (light ochreous or 

 ochraceous-buff) . Thorax : dorsum without markings in either sex, sparsely clothed 

 with glistening ochraceous-buft" hairs ; scuiellum agreeing in coloration with remainder 

 of dorsum, and bearing in both sexes two central and two lateral bristles, as also 

 several short hairs. Abdomen in both sexes clothed with pale yellowish hair.
