dentate. The male differs from the female in having the 

 abdomen glabrous along the middle, with the apical segment 

 impressed on each side ; the hind tibiae are of very different 

 shape, and the first joint of each tarsus is more noticeably 

 inflated. In Blackburn's table the species would be associated 

 with spinicollis, but the male differs from the male of that 

 species, as also of distincfa, in the hind tibiae having the apical 

 portion longer, the excavation of the apical slope not bounded 

 behind by a conspicuous tooth, and the middle of the tibiae 

 more conspicuously dilated on the under-surface ; the basal 

 segment of abdomen is also different. The hind tibiae are 

 suggestive of those of clwysura, but the apical slope is some- 

 what shorter, less flattened out, less shining, and not longi- 

 tudinally concave on the lower surface, and on that species 

 there is no trace whatever of the median inflation. From 

 varians it also differs in the apex and middle of the hind tibiae. 



Edusa chrysura, Germ. 

 PI. viii., figs. 109-111. 

 This species appears to be confined to South Australia and 

 the western parts of Victoria. 



Edusa suturalis, Clip. 

 PI. viii., fig. 112. 

 This species occurs in New South Wales and Victoria, as 

 well as in South Australia. 



Edusa viridipennis. Boh. 



Many specimens from Sydney and near same (Galston and 

 National Park) probably belong to this species, but differ from 

 the description in having the front femora armed, the tooth, 

 however, is so small that it could easily be overlooked, and it 

 is invisible from most directions. The clypeus was described 

 as "rufo-testaceis," but almost certainly (as with the similarly 

 described puherula and evanesce ns) it was the labrum that was 

 meant. The elytra of the females vary from bright-green, 

 through golden-green, to golden. 



Edusa evanescens, Boh. 



The femora of this species were also described as unarmed, 

 but on the front pair a very minute tooth (appearing like a 

 speck of dust) is visible from certain directions; but it is so 

 extremely small that it is invisible from most directions, and 

 distinct from none. The male (as also the male of the preceding 

 species) has a small median fovea on the fifth abdominal 

 segment. •
