NOTES ON APHIDES FROM SUTHERLAND 



55 



females were common, apterous viviparous females rare ; 

 only one alate viviparous female was taken. 



Mysocallis coryli, Goetz. — Alate viviparous females and 

 larvae occurred sparingly on the leaves of hazel at Inveran, 

 Invershin. 



Myzocallis inyricce, Kalt. — This species occurred sparingly 

 upon the under-surface of the leaves of Myrica gale at 

 Inveran, Invershin, in September 1920, and was also taken 

 at Rogie Falls, Strathpeffer, in the end of September 192 1. 

 Apterous oviparous females were most common, but a few 

 alate viviparous females and an alate male were found. 

 This species was described by Kaltenbach (4) as Aphis 

 myric(B in 1843, and Walker (6) has recorded it from 

 " England." Mr Laing has kindly compared my specimens 

 with the ApJiis iiiyriC(B of Walker's Collection, and they are 

 undoubtedly the same species. As no detailed description 

 has yet been published of this species the various forms are 

 here described.
