OF NEW ZEALAND. 585 



behind ; there is scarcely any visible punctation, none on the dorsum. 

 Scutclliim sub-oblong. The elytra are oblong, with jjrominent shoulders, 

 the sides are margined, sub-parallel, widest behind, the apex rounded, 

 but with a not very close suture ; there is on each an obtuse basal 

 elevation, besides the less distinct, and more elongate, humeral one ; 

 the middle portion is depressed, and it is there the spot or abbreviated 

 fascia is situated. The femora incrassated, tibire flexuose. In sonic 

 varieties the white elytral spot has an infuscate or purplish margin. 



Length, 2-3 lines. 



As there seems to be some diversity of opinion regarding this 

 species, I have drawn up the above description from specimens in my 

 own collection ; these had been obtained at Auckland, Tairua, and 

 Whangarei. 



1022. Z. gUttigerum, Westiu. ; Arc. Ent, ii., /. 28. This 

 species scarcely differs from the preceding in form, so far as I am 

 acquainted with it, yet the prothorax seems to be rather more slender, 

 and less dilated laterally, and the tibiae are less, if at all, flexuose. 



In one of my specimens, from Canterbury, the ground colour is of 

 an uniform bluish-purple, the elytral spot yellow ; the base of the 

 femora pallid ; the tip of the joints of the antennae from three to six, 

 and the whole of the other joints, fuscous ; the tibiae and tarsi fusco- 

 testaceous. 



An Auckland variety is of a violet-brown ; others make a nearer 

 approach to the colour of Z. minutiim. 



The propriety of regarding these varieties as two distinct species, 

 appears to me somewhat doubtful ; had my specimens from the South 

 been well set out I should have been in a better position, but the legs 

 are so contorted that I have been unable to decide whether they are 

 really bent naturally, or not.
