Diptera Nematocera from Ceylon. 201 



identical and the coloration is practically the same, the only 

 difference being that the Seychelles specimens have a more or 

 less distinct dark fascia near the apex of the wing, which in 

 the Ceylon specimens is so faint as to be practically absent. 

 The lateral ocelli are absolutely contiguous with the eye- 

 margins and the subcosta is very faint in its apical portion, 

 not distinctly reaching the costa. These two peculiarities no 

 doubt led Biunetti to place the species in Rhymosia, but the 

 general appearance and (apart from the evanescent subcosta) 

 the venation are those of a typical Leiomyia. Precisely the 

 same peculiarities are exhibited by Leia seychellensis, End., 

 and by some undescribed African species which I have 

 examined. Brunetti's Rhymosia annulicornis and R. hume- 

 ralis are doubtless also species of Leiomyia. Leiomyia, 

 Rond. (emended form of Lejomya, Rond.), is the name which 

 should be used for Glaphyroptera, Winn. Leia, Mg., is 

 wrongly applied to it. Since Winnertz was the first person 

 to divide Meigen's Leia, by the rules of the Zoological 

 Congress his interpretation must be followed. Curtis desig- 

 nated a type of Leia which Winnertz did not accept, and 

 Rondani renamed the genus, thinking the original name was 

 preoccupied ; but these facts are altogether irrelevant.

In all but one of these specimens the postnotum is 

 blackish ; in the remaining one, as (presumably) in the 

 Javanese specimens, it is yellowish. The posterior branch of 

 the cubitus (Cu 2 ) is oblique outwardly, not inwardly as in 

 de Aleijere's figure. Nevertheless, I have little doubt that 

 C. jacobsoni is the species before me.

The dark ring on the hind femora reaches almost to the 

 tip, leaving only the extreme knee-tip bare. In this species, 

 as in the preceding, the eyes of the female are contiguous. 

 Both species have till now been recorded only from Java.
