these insects must immediately precede or follow the great group 

 Suhtetrarnera, according as we commence or close the series with 

 such CurculionidcE as Cossonus and its immediate allies.

My attention was drawn to this insect several years since by the 

 circumstance of the stones of a lot of tamarinds almost invariably 

 crumbling to powder in the mouth. Upon examination of some 

 stones which had small holes on the outer surface, I found that the 

 solid alburnum of the seed was perforated in every direction, and the 

 cavities filled with a brownish powder, but I could meet with no in- 

 sects. I then resolved to examine those stones which were appa- 

 rently perfect, and immediately on removing the epidermis I was 

 gratified by finding numerous specimens of a small Calandra occupy- 

 ing the cavities. They were so abundant, that from one stone, by a 

 careful dissection, I extracted between thirty and forty specimens. 

 In one or two instances I met with the larva and pupa. I need 

 hardly add that the insects in all stages were dead, having, in the 

 preservation of the tamarinds, been exposed to a boiling heat. 



It seems evident, from my having found both larva and pupa in 

 the stones, that they, and not the fruit generally, are the proper food
