be doubtful, should also be referred to .Haplouycliiufe ; and to 

 these I would add another, Sigastus. Beginning with Aolles, 

 without a claw-joint, and passing to Haplonyx, with a very short 

 claw-joint and one claw (it deserves notice that no insect is 

 known of a claw-joint without a claw of some sort), we come to 

 Sigastus, with the claws united in a great part of their extent, 

 then to Metatgges, with a short claw-joint, and the claws free, 

 and lastly to Phgsarchus, with tarsi of the ordinary character.

The assumed male is so very dissimilar, that I hesitate to de- 

 scribe it as such, the sculpture of the elytra being quite dif- 

 ferent. The female is one of the largest of the Australian Cur- 

 culionidae, and when fresh is nearly white. Mr. Du BoUlay 

 informs me that he has seen a Wattle-tree (Acacia, sp.) covered 

 with it, and then the tree is soon stripped of its leaves. The 

 males (P) are less common than the females, and have three nearly 

 pure white stripes on the elytra. They have also the large 

 conical tooth on each side of the br^...ji/, directly in front of the 

 anterior coxa), as in the female.
