AHCHITECTUHE OP MOTHS. 



Stands in a perpendicular position, it is necessary, 

 by some mechanical contrivance, to elevate it. To 

 obtain this end, he puts in operation the same sort 

 of contrivance as man would employ with an inclined 

 obelisk, by attaching to the point of the pyramid 

 threads, as man would do cables, and then, applying 

 the weight of his own body in opposition, raises it 

 to the perpendicular.* 



A species of moth, which feeds on the lilac, forms 

 a habitation for itself within the leaf of that tree. 

 This it rolls up at the point of the leaf, by com- 

 mencing at one end, and fixing and pulling its 

 threads till it becomes nearly the shape of a scroll 

 of parchment. Another species pursues a different 

 method with lilac leaves. By a process similar to 

 the above, it contrives to bring the extreme edges of 

 the leaf together in the manner of a hollow tube, 

 leaving it open at the bottom and point for its egress, 

 as represented in the following figure : — 



The Small Green Oak Moth, {Tortrixviridana,)
