belongs to it. There are specimens in the- Museum from New 

 South Wales, Tasmania, and South Australia. In Masters' 

 Catalogue bicolor was recorded as from King George Sound, 

 but probably in error; in the original description New Holland 

 was the only locality given. Reference to the figure (pi. ii., 

 fig. 1) was also omitted. 



Zonitis. 



A curious sexual feature that appears to have been 

 entirely overlooked hitherto ( 10 ) is the presence, on the males 

 of many species, of a curious notch on the front femora. On 

 sedilloti, violaceipennis, and purpureipennis it is a simple 

 notch on the upper-surface near the apex. On hi 'partita Oi) 

 there is also a notch, but a depression is continued for a short 

 distance towards the base from the notch, the depression being 

 visible only from above. On aspericeps, rugosipennis, and 

 rostrata, and to a less extent on cyanipennis, the upper-surface 

 from the notch to the base appears to have been pared down, 

 so* that near the apex of the femur there appears to be an 

 obtuse tooth projecting backwards. It appears to be almost 

 confined to the species having more or less metallic elytra, 

 although apparently not present on the males of every species 

 having such elytra. 



Zonitis bizonata, Macl. 



The original description of this species was simply a brief 

 comparison with apicalis; but a specimen from Mackay (from 

 the late Rev. T. Blackburn's collection) and two from Palm 

 Island and Cairns (from the Macleay Museum) now before 

 me were so named, and I have no doubt correctly so. The 

 Mackay specimen has the abdomen infuscate. All three have 

 the antennae entirely dark, except the base of the first joint. 



Five specimens from the Coen River differ in having 

 the two basal-joints of antennse entirely pale, and the pale 

 median portion of the elytra of variable extent, but consider- 

 ably less than on the others, and two of them have the 

 abdomen slightly infuscated. One has the elytral punctures 

 slightly but noticeably stronger than on the others. 



The dark parts of the elytra are sometimes of an almost 

 plain black, but usually have a purplish or bluish gloss. On 

 the prothorax there is usually a rather vague subfoveate 

 impression on each side of the disc, but they vary from prac- 

 tically absent to rather conspicuous. 



(10) At any rate on Australian species of the genus; and it is 

 not mentioned by Lacordaire. 

 (ii) A non-metallic species.
