N.B. — The author places this simply- in " Aedeinae," without 

 any more definite note as to its exact position, so I place it here at 

 the end of this sub-family.

Sub-Family CORETHRINAE. 



Corethra and its allies form a sub-family of Culicidae, and 

 cannot morphologically be separated from this family. The 

 absence of a biting mouth, and the absence of scales on the bod}' 

 are quite secondary characters. 



Moreover, the discovery in Ceylon quite recently by Major 

 MacDougall, R.A.M.C, of a new genus which Dr. Annandale has 

 described as Ramcia^ irrevocably links together, on account of its 

 undeniably intermediate nature, the two groups Culicinae and 

 Corethrinae. The short, feeble proboscis and absence of scales on 

 the head, body and legs approximate it to the Corethrinae, the 

 presence of scales on the distal half of all the longitudinal veins 

 connects it with the Culicinae. Two peculiarities of venation 

 distinguish it : the ist longitudinal vein ends soon after the 

 middle of the wing, running parallel to the auxiliary vein, instead 

 of reaching the distal margin as in both Culicinae and Corethrinae, 

 in this peculiarity xesemhXmg Phlehot omits ; and, secondly, the 2nd 

 longitudinal vein begins almost in a line with the origin of the 3rd 

 and comparatively close to it instead of some distance before it, as in 

 both Culicinae and Corethrinae. Only the male is known, but the 

 larva and pupa were also obtained and from the characters of 

 these Dr. Annandale considers its total affinities lie mainly with 

 the Corethrinae. 



Two short papers of mine ^ thoroughly investigate the S3'no- 

 nymy of Corethra, 'Mg., Sayomyia, Coq., and Chaoborus, Lichten- 

 stein, with the result that it is found that no species of Corethra, 

 Mg. , occurs in the East, the genus being apparently restricted to 

 two or three European species. The genus Sayomyia is antedated 

 b}^ Lichtenstein's Chaoborus, as admitted by Coquillett himself, 

 and both asiatica, Giles, and cornfordi, Theob., certainly belong here, 



1 Thus named, by special request of Major MacDougall, after the Royal 

 Army Medical Corps.
