 coloured markings near the cornicles. 



Davis in his recent paper (Bull. 112, U. S. Dcpt. Agri., 1914) 

 points out that in America avence also passes the winter as viviparous 

 females at the lower parts and roots of wheat and other grasses. 

 In the latitude of La Fayette, Indiana, it winters either as viviparous 

 females on grain and grasses or in the egg stage on apple and pear. 

 Further north, he says, this species is probably unable to winter 

 in an>- but the egg stage, whilst in the southern parts of the United 

 States they may live o\cr winter as vi\iparous females only, no 

 egg stage appearing. He thus concludes that the apple is not a 

 necessary alternate host. In a recent letter to me this authority 

 thinks that my Siphocoryne splendens from Egypt* may be the 

 same as avence, but it differs markedU- in structure, and I have 

 never seen avence crimson and green in Britain, but Professor 

 Davis says it may be so in America.

 and including the cephalic wing margin; the other much longer,
