did it with its teeth cut out a smooth road ; on the contrary, it did not 

 cut a single hair, till it selected one for the foundation of its intended 

 structure. This it cut very near the cloth, in order we suppose to have 

 it as long as possible, and placed it on a line with its body. It then im- 

 mediately cut another and, placing it parallel to the first, bound both 

 together with a few threads of its own silk ; the same process was re- 

 peated with other hairs, till the little creature had made a fabric of some 

 thickness ; and this it went on to extend till it was large enough to 

 cover its body, which (as is usual with Caterpillars) it employed as a 

 model and measure for regulating its operations. We remarked, that it 

 made choice of longer hairs for the outside than for the parts of the 

 interior, which it thought necessary to strengthen by fresh additions ; 

 but the chamber was ultimately finished by a fine and closely woven 

 tapestry of silk. We could see the progress of its work by looking 

 into the opening at either of the ends, for at this stage of the structure 

 the walls are quite opaque and the insect concealed. It may be thus 

 observed to turn round, by doubling itself and bringing its head where 

 the tail had just been, of course the interior is left wide enough for this 

 purpose, and the centre indeed where it turns is always wider than the 

 extremities. The effluvium of camphor or turpentine will kill them 

 when in the winged state, which is the time when the mischief is first 

 done ; and if camphor is laid in the drawers or other places, were 

 woollen or furs are placed, it will preserve them from being destroyed ; 

 but this will have no effect if they have already laid their eggs, and 

 seldom upon the Caterpillars, for they wrap themselves up too closely to 

 be easily reached by any agent except heat. This when it can be con- 

 veniently applied, will be certain either to dislodge or kill them ; when 

 the effluvium of turpentine however reaches the Caterpillar, Bonnet 

 says, it falls into convulsions, becomes covered with livid blotches and 

 dies. 



The GONEPTERYX RHAMNI ; or Brimstone Butterfly, is a very pretty 

 insect ; it appears the middle of February, beginning of June, and in 

 autumn. Wings two inches and a half angular, primrose yellow in the 

 male, greenish white in the female, each with a darker spot ; Caterpillar 

 pale green with a whitish stripe on the sides ; feeds on the buckthorn 

 and berry bearing alder. 



The CATERPILLARS of a family of small Moths (Tineidcz), which feed 

 on the leaves of various trees, such as the hawthorn, the elm, ' the oak, 

 and most fruit trees, particularly the pear , form habitations which are 

 exceedingly ingenious and elegant. They are so very minute that they 

 require close inspection to discover them, and to the cursory observer 

 unacquainted with their habits, they will appear more like the withered 

 leaf scales of the tree, thrown off when the buds expand, than artificial 

 structures made by insects. It is only indeed by seeing them move 

 about upon the leaves, that we discover they are inhabited by a living- 

 tenant, who carries them as the snail does his shell. These tents are
