ADDITIONS AND COEEECTIONS TO THE BRITISH LIST OF 

 MUSCID^ AGALYPTRATM. 



BT J. E. COLLIN, F.E.S. 



It is proposed in the following pages to put on record the capture 

 of a number of additional species in this particular group, and at the 

 same time to indicate the many changes which the researches of other 

 stvxdents have made necessary in Verrall's " List " as published in 

 1901. Those marked with an asterisk are new to our Fauna. 



CORDYLUEID^. 



*Conlylura atrata, Zett. — A male of this species, the smallest in the genvis, 

 was taken by Col. Yerbnry at Nethy Bridge (Inverness) on Jime IGtli, 1905 ; 

 its small size (5 mm.) and entirely black legs at once distinguish it. 



Cordylura rufipes, Mg., which appears in italics in the " List " is according 

 to Becker a synonym of C. pubera, ¥., and can therefore be struck out. 



Megaphthalma pallida. Fin. — This is the Cordylura pallida of the List of 

 Reputed British Species. I was fortunate enoiigh to take a female at Orford 

 (Suffolk) on June 20th, 1907. It is a yellow species with no long bristle at the 

 end of the palpi, only one sternoj)leui-al bristle, scutelkim with two bristles, 

 eyes nearly round, and arista with a scattered pubescence. 



Leptopa filiformis, Zett. — Col. Yerbury has taken this species at Porthcawl 

 (Glamorgan) as recorded in the Proceedings Ent. Soc. London for November 18th, 

 1904 ; he also found a specimen at Barton Mills (Suffolk) in May, 1909, and 

 about the same time I caught one in a large wood near Newmarket (Cambridge- 

 shire). There are a niunber of specimens in the Dale Collection at Oxford 

 under the name of Gymnomera dorsata, Zett. It need therefore no longer appear 

 in the " List " in italics. 



Amaurosoma inerme, Beck., armillata, Zett., and Jlavipes, Fin., have been 

 recorded in this Magazine as occurring in Britain, the first two on page 138 

 (1908) the last on page 105 (1909). 



Amaurosoma brevifrons, Zett. — This yellow-legged species with two shining 

 stripes on its somewhat poUinose thorax has been found by Col. Yerbiuy in 

 some numbers at Aviemore (Inverness) towards the end of May, 1904 ; 

 Mr. A. E. J. Carter has also taken it at Musselburgh (Edinburgh) on May 30th, 

 1906, and Mr. J. E. Malloch at Bonhill (Dmnbarton) . The front femora are 

 unarmed, the cltunp of bristles in front characteristic of several species in this 

 genus being absent. Mr. Malloch mentions this species on page 105 of this 

 Magazine for 1908. 



* Acantliocnema nigrimana, Zett. — Mr. Verrall caught a male of this species 

 so long ago as July 22nd, 1872, at Braemar (Aberdeen), but it remained 

 unidentified, probalily because it was an unset specimen making it difficult to 

 see the spur beneath the end of the front tibiae. I do not feel the slightest 

 doubt concerning its identity. 



* Acanthocnema glauca, Lw. — It has fallen to the lot of Dr. J. H. Wood to 

 first recognise this species as being British from a specunen foiuid by him near 

 Tarrington (Hereford) on Jidy 20th, 1909.
