•^). P. iiKidfstd, Winn. : this species is not in our British Lists 

 and is not, in my opinion, well distinguished ivoiwP. fiava, Macq., but 

 I refer to it two males taken at Canford Common, in Dorset, on 

 August 13th, 1904, and a male taken by Col. Yerburv at Much Marcle 

 on August 29th, 1902. 



P. nujriceps, Walk., was probably correctly idontitied by Winnei-tz, 

 as I possess the fragments of a specimen so labelled in Walker's own 

 handwriting, and Col. Yerbury took a male at Goathorn, in Dorset, on 

 June 7th, 1907, and a female at Studland on May ;Jlst, 1907, while I 

 caught a female at Lyndhurst on June 29th, 1885. A specimen labelled 

 Teignmouth was in Eev. T. A. Marshall's collection under the name of 

 Ditomyia vlitafa, and may represent that species of Walker. 



G. P. huineraUs, Winn. : I have but little doubt in referring to 

 this species a male taken by Col. Yerbury at Nairn on May 31st, 1905. 

 I also possess a broken specimen of apparently the same species, taken 

 by the late Rev. T. A. Marshall at St. Albans. Many of the speciesof 

 this genus are probably widely spread, but are so seldom captured and 

 identified that very little is known about them at present. A large 

 black species has often been taken in the New Forest and other largely 

 wooded districts, which is in our Lists as P. semiriifa, Meig. ; it may 

 be that species, or P. hrunnlpennls, St«g., or P. vitripeiinis, Meig. (as 

 identified by Zetterstedt) , and is almost certainly P. concolor, v. d. 

 Wulp ; beyond this, it is probably P. mijcetophiloides, Hardy, in 

 Walker's Ins. Brit. Dipt., but the description is too imperfect for 

 determination. 



7. Scatopse talpie, n. sp. : this species has been included in both 

 the previous editions of this " List," but has never yet been described. 

 It is closely allied to S. inermis in its venation, but is smaller and has 

 the first costal space not much longer than the second (while in *S'. 

 iuermiii it is quite twice as long) ; this distinction in the costal spaces 

 is mainly caused by a more even curve of the second vein, which causes 

 that to end more l>eyond the middle of the costa ; the veins and the 

 pubescence of the wings are blackish (instead of yellowish) . Antennse 

 more clavate. Thorax more compressed, and hearing much less 

 conspicuous dark grey pubescence (instead of yellowish as in S. inermis). 

 Abdomen almost dull black, and with black pubescence, hardly widene<l 

 at genitalia, ending in a sort of terminal flap caused by two blac-k 

 lamellae touching (instead of the brightly sliining widened end of S. 

 inermis, from wliich two narrow lamellrc extend). Hind tibioe thinner 

 at base, and therefore more clavate, and with no obvious pubescence
