P. univittata, v. Ros. Hen- Stein has found this species in 

 most collections under the name of Jlavipes, Fin. He found the two 

 species mixed in Zetterstedt's collection, and doubtless specimens of 

 univittata are to be found in some of our British collections. Fallen's 

 species is in Mr. Verrall's list, and, as I have seen British specimens 

 of both species, univittata is an addition. I have not taken Jlavipes 

 myself, but have seen an undoubted <J taken by Mr. H. W. Andrews 

 at Stradbally, co. Waterford, August 8th, 1906, and a ? , which I think 

 must belong to this species, taken by Mr. Adams in the New Forest. 

 In my collection are four $ $ of univittata taken at Comrie, July 

 9th, 1907, and two <J <J taken in the New Forest, July 3rd, 1905, and 

 kindly given to me by Mr. Adams, who tells ine he found the <£ fairly 

 common in a limited space of ground, but no ? ? . The two species 

 are very much alike, the most obvious difference in the £ being the 

 size of the hypopygium, which is large and conspicuous mflavipes, 

 and much smaller in univittata. The other differences, as pointed out 

 by Herr Stein, are : pubescence on the lower part of the back of the 

 head, yellow in Jlavipes, black in univittata, pre-sutural acrostichal 

 bristles nearer (the two rows) to each other than to the dorso-centrals 

 in jlavipes, further apart in univittata, and bearing tiny hairs between 

 the rows, Jlavipes also has on the under-side of the hind femora, in 

 the (£, a row of much longer bristles than occurs in the $ of uni- 

 vittata.

NOTES ON CERTAIN MYCETOPRILIBM, INCLUDING SEVERAL 

 SPECIES NEW TO THE BRITISH LIST. 



BY F. JENKINSON, M.A. 



The British species of Mycetophilidai seem to be very imperfectly 

 known ; and in some cases what was once known is now forgotten. 

 I know that some attention is being paid to them now ; and probably 

 some of my friends will be able to correct and supplement these 

 notes, which cannot pretend to do much more than record my own 

 captures during the last five years, together with some observations 

 made in the course of my attempts to identify them. Mr. Verrall 

 kindly devoted a day to going through most of the specimens, which 

 now form part of the University Collection at Cambridge ; and thus 

 a higher value may be attached to some of my conclusions, verified
