February, 



This scarcity or absence of usually common species is, however, less re- 

 markable when we take into account the fact, that, though so very many 

 species are found, the great majority of them are individually scarce, so that 

 insects are really far less abundant than in many other places. Hardly any 

 species, comparatively, are pests, while great numbers in my list are repre- 

 sented by but one or two specimens.

A SECOND LIST OF GALL-BEARING PLANTS. 

 BY H. W. KIDD AND ALBEET MULLEE. 



In the October number (vol. v, p. 118) of this Magazine we have 

 attempted to give a list of indigenous and other plants known, or 

 strongly suspected to bear galls, in Great Britain.* 



A few additions to this first list will be found in the enumeration 

 below, which, besides, contains the names of many native and intro- 

 duced plants on which^ as yet, no galls have been found in these 

 islands, but which are known to harbour such abroad. All the latter 

 species are marked with a note of interrogation (?), but, with the kind 

 help of other observers, we hope to be able to remove this doubtful 

 mark, after the lapse of next season, from many of them. We have 

 therefore postponed the publication of our descriptive lists, that we 

 may give our readers the opportunity of communicating any discoveries 

 they may make during the summer, and of increasing our own know- 

 ledge ; though, of course, we are well aware that we cannot expect 

 that all these plants will eventually become known to us as really 

 possessing galls in this country too. "We simply submit this list as a 

 guide, to be followed, but by no means to be implicitly trusted ; and 

 we shall at all times bo glad to hear of any additions or alterations 

 concerning the same. The asterisk marks non-indigenous plants.
