where it not only attains a more gigantic stature than 

 in Porto Santo, but is invariably also more parallel and 

 opake, has the sides of its prothorax more recurved, with 

 the punctures towards the lateral angles almost obsolete, 

 and the strise of its elytra somewhat more evidently 

 punctate*. 



Such examples, however, might be multiplied ad infi- 

 nitum ; and I will not therefore devote further space to 

 the bringing together of facts which it is hardly possible 

 will be disputed, especially as it has been my wish, in 

 the present chapter, merely to enumerate what the organs 

 and characters principally are which are more peculiarly 

 sensitive to change, throughout the Annulose tribes. 

 This I may venture to hope, though briefly, I have in 

 part done ; and I will consequently pass on to other 

 considerations, which, even if somewiiat alien to the im- 

 mediate question of insect instability, should scarcely be 

 altogether omitted in a treatise like this.
