326 Mr. K. J. Morton's Further Notes on 



Stadohia fuscicornis, Sclin. 



More detailed figures of the $ appendages are given by 

 Ris in Mitt, der Schweiz. entom. Gesell., Bd. ix, p. 418. 



S. catonianeUa, McL. 



Klapalek (Bull, internatl. de I'Academie des Sciences 

 de Bolieme, 1900) describes and figures the preparatory 

 stages of this species. He also figures the apex of the ^ 

 abdomen, but the penis is not exserted, and I am unable 

 to say how the structure as a whole compares with that of 

 the other two species. 



S. atra, Hagen. 



I am indebted to Mr. McLachlan for the opportunity of 

 examining abundant material (dry and in alcohol) of this 

 species collected by Mr. Eaton. 



In some of these examples the parts are strongly 

 exserted, and I was enabled to obtain a much more satis- 

 factory knowledge of the structure than formerly. ]\[y 

 earlier figures were taken from an example in which 

 the parts were retracted, with the result thai? Ris quite 

 naturally concluded that these parts showed only a remote 

 similarity to those of S. fuscicornis. The figure now given 

 will on the contrary, I think, serve to emphasize the con- 

 nection between the two, and will also help to explain the 

 homologies of the individual parts. 



Orthotrichia augustclla, McL. 



■Appears to be less common, in Northern Europe at 

 heast, than the following. Its distribution is, however, 

 imperfectly known. I have seen it from Algeria {Eaton). 



0. tctensii, Kolbe. 



This species has been more fully elucidated by Kla23alek. 

 I have taken it in Scotland, and amongst a large number 

 of examples of Orthotrichia seen from Finland, it was the 

 only species of the genus represented. 



Oxyethira ccornuta, Mort. 



Numerous examples have been seen from Finland 



{Silfvenius).
