58 Mr. F. \V, Edwards on some 



IX, — On some Tipulidse (Limoiiiinse) from Ceylon in the 

 British Museum Collection, with Descriptions of Eight new 

 Species. By F. W. Edwards, B.A. 



(Publislied by permission of the Trustees of the British Museum.) 



The insects treated of in this paper were contained in three 

 collections made in Ceylon and presented by the collectors 

 to the British Museum : — 



(1) Mr. E. E. Green's collection, made between 1888 



and 1897. 



(2) Lt.-Col. J. W. Yerbury's collection, made in 



1890-92. 



(3) Mr. T. Bainbrigge Fletcher's collection, made in 



1907-8. 



Only the insects belonging to the subfamily Limoniinse 

 {Tipulid(B brevipalpi, O.-S., Limnobiidcs, auctt.) are here 

 described. These all belong to widely distributed genera, 

 but many of the species are of considerable interest. The 

 occurrence of the genus Styringomyia in this region is 

 interesting; it seems to have a very wide range in the tropics 

 of the Old World. 



Of the sixteen species represented in the three collections, 

 eight are here described as new, while of the remaining eight 

 only four {Eriocera crystalloptera, E. humberti and E. albo- 

 notata, and Conosia irrorata) had previously been recorded 

 from Ceylon. The species of Eriocera, as has been noticed 

 before, vary to a rather remarkable extent, particularly in 

 their neuration.

 xiv. p. 390, pi. ii. fig. 3 (1857) (as Limnobia).\ 

 Syn. Dicranomyia saltans, Ost.-Sack. Berl. eut. Zeit. 1882, p. 88. 



Although there are marked differences between this species 

 and T. aurijoennis in the neuration, it is here referred with- 

 out any hesitation to the genus Thrypticomyia. In the 

 structure of the antennte, and the shape of the wings and 

 abdomen, there is hardly any divergence; these three 

 characters I regard as the essential ones of the genus. 



As the original description was rather short, and in Dutch, 

 I append another : — 



Antenna 14-jointed, but the last joint constricted in the 

 middle, so that they appear almost as though they were
