XIvIII. REVIvSION OF THE ORIENTAI, 

 Iv.E P T I D ^ . 1 



By E. Brunetti. I 



The present paper is an endeavour to recognise the described 

 Oriental species in this family and to add some new ones existing in 

 the Indian Museum collection. Some of these latter bear names by 

 Bigot (apparently nomina nuda), with " sp. nov." affixed, and 

 these I have described herein. Most of them are placed wrongly, 

 generically, and one " sp. nov." which he calls " Leptis dichroma " 

 is a Plecia {Bibionidcp.) and is in too dilapidated a condition to des- 

 cribe. My thanks are due to Mr. C. O. Waterhouse of the British 

 Museum for some valuable information respecting some of Walker's 

 types and Rondani's genus Leptipalpus , and also to Prof. M. Bezzi 

 for notes on the latter genus. 



SURAGINA, Wlk. 



1. illucens, Wlk. . . . . . . Celebes. 



2. signipennis, Wlk. . . . . Gilolo. 



Walker mentions the great length of the discal cell (" nearly 

 six times longer than broad ") as characteristic of his genus, and 

 Osten Sacken notes its affinity with Atherix (Berl. Ent. Zeits., xxvi, 

 loi) ; as Walker had labelled with the generic name Suragina, the 

 specimen which Osten Sacken makes the type of his species Atherix 

 limhata. The latter author seemed doubtful of the validity of 

 Suragina. Osten Sacken does not mention the proportionate 

 shape of the discal cell in his limhata. In the five species of Atherix 

 that I have been able to examine it is only from 3 to 4 times longer 

 than broad, and in the two common European species {marginata 

 and ibis) only slightl}^ over 3 times. (In my measurement, I have 

 regarded the ' ' breadth ' ' as its breadth in the middle — or the 

 average breadth.) 



Failing a comparison with types, it is well to let Suragina stand 

 provisionally. Moreover Walker says the antennae have the third 

 joint round, whereas in Atherix it is kidney-shaped. 



From the descriptions, 5. illucens is a cinereous black species, 

 with two large lateral testaceous spots at the base of the abdomen, 

 the tip of which is also testaceous ; whilst in S. signipennis it is 

 black, with hoary tomentum. The legs are differently coloured, 

 but the size of both species is about identical. 



1 Since concluding this and the succeeding paper, I have seen two new species 

 of Chrysopilus , two of Bombylius and one of Geron, all acquired by the Indian 

 Museum : these will be described shortly. — E. Brunetti,
