following : " the species are found exclusive!}^ in temperate countries, 

 being wanting in the tropics ; the larvae live only on plants of the 

 family Compositae, and often make galls " (Bezzi). 



The genus Urophom was proposed by Robincau-Desvoidy in 1830, 

 one of many that he formed out of the large genus Trypeta of Meigen, 

 and from this date onwards the name of the species Urojihora solstitialis 

 Linn., has been accepted by most entomologists. 



The following is a list of the principal synonyms of the species as 

 given in Loew's monograph.

Geographical distribution. 



Urophora solstitialis has been recorded from nearly all the countries 

 of Europe ; a list of these records is given by Schiner (1858). Mr J. E. 

 Collin informs me that it is common and widely distributed in England ; 

 Fitch (1872) records it from Suffolk ; Wingate (1906) from Hesleden, 

 Durham ; Connold (1901) from Hastings, Sussex. I have collected the 

 galled flower-heads containing larvae of this species at Prestatyn, 

 North Wales, and also at Port Erin, Isle of Man ; and Dr A. D. Imms 

 collected a few galled-heads at Llwyngwril, Merionethshire. Professor 

 J. W. H. Trail of Aberdeen very kindly sent me the following list of 

 localities in Scotland where galled heads containing the larvae have 

 been obtained : Aberdeenshire and Kincardineshire, especially in the 

 valley of the Dee ; near Dunkeld and elsewhere in the valley of the Tay, 

 from Glen Falloch, and from Loch Lomond in Perthshire ; in these and 

 in other localities the galls are abundant. I am indebted to Professor 

 G. H. Carpenter of Dublin for a note on its occurrence in Ireland ;
