in first-rate condition show very clearly the two long and two short 

 black lines (of scales) on the thorax, the ground colour of the thoracic 

 scaling being whitish-grey, and the head-scales of the same colour ; 

 the tips of the femora, too, are conspicuously white, even to the naked 

 eye, while the basal half of the hind femora is moi-e uniformly and 

 evidently whitish in this species than in any other British gnat. 

 Olivier's statement that his species is of the size of the common 

 gnat is true of 0. lateralis, though specimens are often found rather 

 larger than C. pijnens. C. Iwrtensis, however, is consistently and 

 considerably smaller than the average G. iripiens ; moreover, it seems 

 to be a purely Mediterranean species, having been recorded only from 

 Italy, Palestine, and Algeria. 



The writer, therefore, considers that the evidence here ])rought 

 forward in favour of the view suggested is fairly conclusive, and the 

 following synonymy may be given for the species : —

Haliplus browncanus, nee. H. hrownci.— In my description of this species in 

 last month's number of this Magazine (anted, p. 75), I intended to write the 

 name *' browneanus," but by a pardonable misunderstanding it was printed 

 " broi'jnei." I selected the termination in accordance with the old convention 

 that when a species is merely in lionoiu- of a person the termination should be 

 " anus " or " ana." I did not know why the name I selected was chang'ed, and 

 under these circumstances I think the name of this insect should be hrow7iea7ms, 

 as the types are labelled in my collection. In the same communication I 

 mentioned " H. multiniaculatus" as anot]wr Haliplus that is probably a member 

 of our British fauna. This was a lapsus calami for " H. multipunctatus." I 

 recognised the error after I sent off the note, and intended to correct it -when 

 reading the proof, l)ut I had no opportunity of doing this. — D. Sharp, Brocken-
