these two species. I am inclined to agree with him, as one of my 

 hz)iiopa males has only one strong pre-apical bristle on the hind 

 femora instead of two, while in the specimen of ordinata there 

 is no bristle otherwise they agree with the descriptions in Becker's 

 Monograph.

Rose Chafer (Cetonia aurata, L.) in Argyllshire. I have 

 much pleasure in recording the occurrence of Cetonia aurata, L. in 

 Argyllshire. An example was found by Sheriff Guy crawling on the 

 painter of a boat at Carsaig Bay jetty, north Knapdale, on the 

 1 2th July 1 91 9. The specimen was shown to, and identified by, 

 Mr Percy H. Grimshaw, who informs me that the species is rare 

 in Scotland, and has hitherto only been recorded from the Clyde 

 and Solway faunal areas. Henry H. Brown, Edinburgh. 



Asellus meridianus, Racovitza, in Scotland. It may be 



of interest to record that on examining two small collections of 

 freshwater isopoda, one from St Andrews and the other from 

 Helensburgh, the newly described species Asellus meridianus, 

 Racovitza, hitherto confused with A. aquatiais, Linne, was found 

 to occur in both collections. Walter E. Colltnge, St. Andrews.
