thorax ; hind angles of thorax quite indistinct, and not applied 

 to shoulders of the elytra, so that a gap or notch is left on each 

 side between the thorax and elytra ; its surface is covered 

 with fine, greyish, somewhat variegated hair-like scales. Ely- 

 tra rather long and narrow, clothed with somewhat variegated 

 greyish scales, and in front of the extremity bearing a trans- 

 verse blackish mark ; they bear near the suture four rather 

 strongly elevated callosities, the scales on which are black ; 

 the front pair of these elevations are near the base, the hind 

 pair just behind the middle. The legs are yellowish, with 

 indistinct darker marks. 



Sent from Tairua by Captain Broun. 



Ohs. I. I have seen only three mutilated individuals of this 

 species : two of them bear a pair of strongly elevated tubercles 

 on the head just anterior to the eyes ; the other specimen is 

 smaller, and has the head and rostrum narrower, and has no 

 trace of the tubercles just mentioned. It is perhaps a female, 

 while the larger individuals are no doubt males. 



Ohs. II. This species is very distinct from Lawsonia longi- 

 cornis and variabilisj by its tuberculated elytra, by the differ- 

 ently formed basal portion of the thorax, by the differently 

 shaped eyes, and by the greater space between these *nd the 

 upper margin of the antennal cavities.

Antennae just about as long as the insect (3 millims.), yellow, 

 with the club black, and the apex of each joint from the third 

 to the eighth also black, but the extremity of each of these joints 

 only indistinctly nodose, the ninth joint not quite so long as 

 the tenth and eleventh together. 



Tairua : a single individual sent by Captain Broun. 



Ohs. This insect differs from A. jjhymatodes only in the 

 colour and form of the antenna ; and if the individual of that 

 species with untuberculated head prove to be only an unde- 

 veloped male, then A. liekcra will perhaps be found to be only 

 the iemale of A. pliymatodes.
