Rhodites eglanterise. 



It is remarkable how these galls elude notice until a careful 

 search is made among the wild rose-bushes. One of the best 

 and quickest ways of finding them is to stoop down and look 

 from below upwards among the stems and leaves. On some 

 leaves they are very numerous. The author found on one 

 occasion a twig of Rosa canina having upon it three leaves 

 growing close together. One leaf supported four galls, another 

 seven, and the third fifteen, making a total of twenty-six galls 

 on twenty-one leaflets. All the galls were on the underside of 

 the leaflets. It appears from observations made of a large 

 number of leaves, that the styles do not bear galls. The galls 

 grow from all parts of the leaf, including the main stalk. The 

 stems also are occasionally attacked by the parent insect, when 

 a growth similar in all respects to those on the leaf is produced. 

 The galls are of a more or less globular shape, and mostly of 

 a smooth surface which is sometimes marked with slight de- 

 pressions and sometimes with small tubercles. They have the 

 appearance of being firmly attached, but this is apparent only. 

 A delicate and easily disrupted pedicle forms the connecting 

 point, which is so slight as not to be observable while the gall 

 is on the leaf, nor is the point of attachment visible on the 

 upper side of the leaflet. 



The illustrations are of specimens gathered at Hastings by 

 the author.
