bristles and a comb of 27 spines. The mesonotum is densely hairy from the base 

 to the postmedian row of long bristles. There are thi-ee rows of bristles on the 

 abdominal tergites, the first four tergitcs bearing also an apical comb of short spines. 

 This comb consists of 22 spines on the fii-st Icrgite, and of 2 on the fourth. The 

 hind femur bears 4 bristles subventraliy before the apex.

 of the postmedian row is placed beneath the stigma. The seventli sternite is 

 sinuate, the lobe situated above the sinus being obliquely excised. On the eighth 

 tergite there are no hairs above tlie stigma, while there are 6 bristles at the apical 

 edge and 5 or 6 near the ventral edge.

A RARIi; BRITISH FVNGVS-MIDGE {CEROPLATUS LINEATUS,¥ABn.) 

 RE-DISCOVERED IN LONDON. 



BY E. E. AUSTEN. 



This morning a male of tlie above species was taken by my 

 boy -attendant, C. Hill, on the window of the Diptera lioom here. 

 C. lineatus is a large, dark-coloured species, with yellow, brown- 

 striped thorax and conspicuously blotched wings ; the specimen which 

 is the subject of this note measures 9^ millimetres in length. In 

 Mr. Verrall's " List of British Diptera," 2nd edition (1901), p. 10, 

 C. lineatus appears in italics as requiring confirmation. On turning 

 to Fabricius's original descri[)tion of the species (" 8ystema Entomo- 

 logia)," 1775, ]). 751) I find the following sentence : " Habitat in 

 Anglia: capt. in Mus. Brit., d. 21 Jun." In Walker's " Ii]Becta 

 Britaitnica.— Diptera," vol. iii (1856), p. 67, the species (under the 

 name Platijnra Jineata) is recorded as " liare. In the British 

 Museum"; and the Old Collection of British Diptera still contains 

 half a dozen faded specimens of the species, all of which, how^ever, 

 like the rest of that collection, are without locality-labels. Con-
