HABITATIONS OF INSECTS. 453 



be inhabited by the larvae of Curculio contractus, Ent. 

 Brit., and Hhynchcenus assimilis, F. From the knob-like 

 galls on turnips, called in some places the anbury, I have 

 bred another weevil, {Curculio pleurostigma, Ent. Brit., 

 Rhynchccnus sulcicollis, Gyll.) and I have little doubt that 

 the same insects, or species allied to them, cause the club- 

 bing of the roots of- cabbages. It seems to be a beetle of 

 the same family that is figured by Reaumur a , as causing 

 the galls on the leaves of the lime-tree. Others owe 

 their origin to moths, as those resembling a nutmeg which 

 Reaumur received from Cyprus 5 ; and others again to 

 two- winged flies, as the woody galls of the thistle caused 

 by Tepkritis (Musca, L.) Cardui c , and the cottony galls 

 found on ground ivy, wild thyme, &c, as well as a very 

 singular one on the juniper resembling a flower, described 

 by De Geer d , all which are the work of minute gall-gnats 

 (Cecidomyicc, Latr., Tipulcc, L.). Some of these last con- 

 vert even the flowers of plants into a kind of galls, as 

 T. Loti of De Geer e , which inhabits the blossoms of Lotus 

 corniculatus ; and one which I have myself observed to 

 render the flowers of Erysimum Barbarea like a hop 

 blossom. A similar monstrous appearance is commun 

 cated to the flowers of Teucrium supinumby a little fleldi 

 bug, Cimex (Tingis, F.) Teucrii of Host f , and to another 

 plant of the same genus by one of the same tribe de- 

 scribed by Reaumur s. In these two last instances, how- 

 ever, the habitations do not seem strictly entitled to the 

 appellation of galls, as they originate not from the egg,
