general plan ..I structure, but it differs in (he f«»| lowing points : It has a 

 straight snout, with the mouth in front of it and nor. below, the jaws 

 being hooked outwards a .<! distinctly visible. The horns are long, with 

 a slender club, and ar.> inserted in the middle of the snout. The eyes 

 almost meet above, heing only separated by a very narrow ridge. The 

 wing cast's extend to the tip of the hody. 



The peculiar and characteristic shape of this insect (PI. II. 1) will 

 distinguish it without further description. In the male the snout is 

 longer and stouter than in the female, ami its anterior half, as well as 

 the breast, is covered with a dense yellow down. 



The gruh of an allied species, Rhina nigra, Drury. has heen figured 

 by Coqueivl, who found it abundant in the decayed interior of a screw- 

 pine ( l>u„<h,,r>.s Htilis) in Madagascar (10). 



The writer knows of no other description of the habits or economy 

 of any species of Rhina. Possibly some of the smaller grubs so 

 frequently found in the stem or the rotting cabbage of decayed palms 

 are those of the Bearded Weevil. 



Nothing much is known of causes which check the weevil's increase.

 reference to this fact will be found in the next chapter. 



Attention is drawn to the following points, as being likely t 

 further attentive observations made to determine them : — 



1. The spots usually selected for egg-laying in wounded and i 

 trees, care being taken not to mistake the work of any other ii 



will be worth while to make observations at that time. 



2. The length of time passed in each of the different stage
