B. alni) no doubt it has hitherto been mixed up in collections. The 

 transverse streak on the crown and face, the clear elytra, in both 

 sexes, and the spot on the transverse nerves are excellent characters 

 whereby to distinguish it from either of the other British species. 



I am indebted to my friend, Mr. T. J. Bold, for calling my atten- 

 tion to this interesting addition to our fauna. The specimens he 

 submitted to me were taken at Gibside (Durham), and Grosforth and 

 Wooler (Northumberland), by general beating. I have also detected 

 specimens in my own and Mr. Douglas's collections, taken at Cobham 

 Wood, Folkestone and Dartford Heath. Time of appearance — July, 

 August, and September.

 this group : —

 Dr. Sahlberg, and he gives me permission to translate and publish

1. O. cassidea, Thoms. Tour observation that this cannot be 

 Fallen's species appears to me to be quite correct, judging from 

 Fallen's description, which agrees much better with O. cassidea, Fieb., 

 = hrumica, Grerm., but which is not known to me, aud which Thomson 

 does not knoAv from Scandinavia. On the other hand, it appears to 

 me that Thomson's species is certainly identical with 0. cervina, Fieb. 

 The definition "prothorace angulis anticis rotundatis " is indeed not 

 exact, but examples vary somewhat iu this i-espect. Fieber also him-
