First found in the British Islands at 

 BaUrmote, Co. SUgo (E. F. S.), this 

 beautifullTinaiked little species has since 

 been discovered at Borrisokane. If. Tip- 

 perary (E. A. P.) ; KUcarrT Bridge 

 and Fenagh, Co. Carlow (D. E. P. B.) ; 

 Carrickmines, Co. DuhHn (J. 2f. H.) : 

 Kiltoom, Co. Eoscommon (A. 'W. S.) ; 

 and at Ballj-quintin Point, Co. Down 

 (D. E. P. B.;, where it occurs ia con- 

 siderable numhers. It has been found 

 at two or three places only in England, 

 but ranges over the greater part of 

 northern and central Europe in scattered 

 localities (Budde-Lund).

So far as our present knowledge goes 

 this seems to be undoubtedly an intro- 

 duced species, as it has hitherto been 

 found only in greenhouses. It occurs 

 in the south of England, however, in the 

 open (Webb and SUlem), so may possibly 

 be found eventually out of doors in this 

 country too. This species was first 

 noted in Ireland, by one of us (F. H. F. ), 

 at HUlsborough, Co. Down, and was 

 found at almost the same time by 

 Mr. J. JS^. Halbert in the hot-houses in 

 the Botanic Gardens, Glasnevin.^ The 

 only other places at which it lias been 

 taken in Ireland are Belvoir Park 

 (2f. H. F.), Crawfordsbum (E. W.), and 

 Bangor fD. E. P. B.;, Co. Down: and 

 in Belfast, Co. Antrim (H. L. 0.). 



M. DoUfus gives the measurements 

 of this species as 15x7 mm. ; but the 

 largest specimen we have obtained in 

 Ireland so far only measures 10 mm. in 

 length, the great majority only attain- 

 ing to about 8 mm. We have specimens 

 from the bank of the river Avon, Somer- 

 set, which measure 14 x 7'5 mm., one 

 of these being of a pale tawny colour 

 tinged with pink, and having light 

 brown markings. This of course is a 

 specimen preserved in spirit ; but in 

 OUT experience the colours are little 

 aflEected thereby in specimens of this 

 genus. 



On the Continent it is found in France, 

 Spain, and Italy, in which latter country 

 it is common.
