ADDITIONS AND COERECTIONS TO THE BRITISH LIST OF 

 MUSCIDM AGALYPTBATM. 



BY J. E. COLLIN, F.E.S. 



(Continued from Vol. xlvi, page 178). 



MICEOPEZID^. 



Calobata sellata, Mg., described from a British specimen is considered by- 

 Becker to be a synonym of cibliaria, L., bnt to my mind the description of the 

 arista as " sehr kurzgefiedert," and the abdomen (female) as having " ziegel- 

 rother Legerohre," points most strong'ly to its being identical with petronella, 

 L. In either case the species sinks as a synonym, and should no longer burden 

 the List. 



Calobata trivialis, Lw. — I cannot separate the specimens iipon which this 

 species was added to the List by Mr. Verrall in 1894, from typical ciharia, L., 

 the male abdominal appendages are exactly the same. Mr. Verrall was prolaably 

 misled by the specimens under the name trivialis in Kowarz's collection, which 

 are representatives of cibaria, L. 



PSILID^. 

 *Psila nigromaculata, Strobl. — This species has only one pair of dorso- 

 central bristles on the thorax, it has the appearance of bicolor, Mg., but the an- 

 tennae are entirely pale, and the sternopleiira is darkened in front of the middle 

 coxae. Col. Yerbiiry and Mr. C. G. Lamb have taken this species at Nethy 

 Bridge (Inverness) in June, and Dr. Wood has fovmd it in Herefordshire. 



*Psila hwneralis, Zett. — I recognise this as a species distinct from nigri- 

 cornis in having a more pubescent arista, as well as being extensively reddish 

 about the humeri. Col. Yerbury found it at Golspie (Sutherland) and Netliy 

 Bridge (Inverness) in June and July. 



Psila pectoralis, Mg. — I have not seen British specimens answering to this 

 species, but those in Kowarz's collection are certainly distinct from nigricornis, 

 they are smaller, the pleiirae entirely pale, and the pubescence of the arista 

 longer. P. pectoralis, /'. nigricornis, and /', Minieralis are considered by some 

 writers synonyms of /'. rossp-. 



J'sila gracilis, Mg., was recorded from Lincolnshire in 1898 by Mr. P. H. 

 Grimshaw, and Col. Yerbury has taken it in Scotland at Nairn, Nethy Bridge, 

 and Golspie in June and July. P. villosula, Mg., is considered to be the same 

 species. 



Chyliza atriseta, Mg. — This is the type of Rondani's genus Mcgachetum, 

 which is recognised as a valid genus in Kertesz's Catalogue. 



Chyliza vittata, Mg., was first i*ecorded as occurring in Britain by tlae Rev. 

 E. N. Bloomfield in this Magazine for 1904, p. 60. I have taken it myself in 

 Dr. Wood's locality of Stoke Wood (Herefordshire). 



Loxocera aristata, Pnz. — I accept Loevv's iutei-pretation of this sjiecies, 

 because an examination of the figure given by Panzer must convince any one 

 that he could not have had albiseta, Schrnk., befoi-e him.
