Waikato (Capt. Hutton). 



A variable species in regard to the colouration of the elytra. 



Note. — The habitat must be understood to be the sea-coast near 

 the river ; I found it on the opposite coast, but not always amongst 

 Algse. 



651. P. atomaria, Pascoe; Ann. Mag. Nat. Hist., September, 

 1875. ^- breviter ovzidi, nigra, squamulis albis sparse irrorata, antennis 

 pcdibusque piceis ; fronte minus sulcata ; protJwraee pone medium 

 latiore, punctis sparsis singulis squama repletis ; elytris sub-rotundatis, 

 baud seriatim punctatis, punctis singulis squamulam albam elongatam 

 erectam gerentibus ; corpore infra pedibusque sparse albo-setosulis.

The silvery white small erect scales dotting the elytra will, inter alia, 

 readily distinguish this species from the preceding.

There are two species of this genus; one, A. ammobioides, the type, 

 is like Ammobius rufus, and is about the same size, apparently scaleless ; 

 but I suspect when perfectly fresh it is otherwise ; the second species, 

 A. albata, is a pretty little insect clothed with close-set white scales 

 having a somewhat varnished gloss, but generally marked with a few 

 dark more or less indistinct spots. All the tibije are armed at the inte- 

 rior angle of the apex with two long spines.
