the middle femora is feeble, and could be easily overlooked, 

 but is alike on both sexes. 



Some specimens recently received from Dorrigo (W. 

 Heron) show a range of metallic colours much as those of 

 chrysura and spinicollis, but on all of them the femora and 

 tibiae are entirely metallic. 



Edusa rufilabris, n. sp. 



d . Metallic-green, in parts with a brassy gloss, labrum 

 and parts of appendages more or less reddish. With short, 

 depressed, stout, whitish setae. 



Head with dense punctures of rather small size, becoming 

 longitudinally and obliquely confluent, and smaller but more 

 sharply defined on clypeus than elsewhere. Prothorax with 

 dense but not very large punctures becoming more or less 

 confluent on sides, interspaces with minute punctures; front 

 angles feebly dentate. Scutellum feebly punctate. Elytra 

 very little wider than prothorax; with dense punctures, trans- 

 verse sculpture conspicuous, except about suture and on parts 

 of the apical slope. Abdomen with fourth segment flat in 

 middle,' almost as long as third and fourth combined, fifth 

 shallowly depressed across middle. Front femora lightly 

 dentate ; hind tibiae at apex rather wide and truncated ; basal 

 joint of four front tarsi somewhat inflated. Length, 6-6 J mm. 



9 . Differs in the usual particulars of the abdomen and 

 tarsi. 



Hab. — Western Australia. Type, in Macleay Museum; 

 co-type, I. 3634, in South Australian Museum. 



A large green species, but readily distinguished from 

 most of the large ones by its non-metallic labrum. The tooth 

 of the front femora, although small, is fairly conspicuous on 

 account of its position. The clothing on the elytra is rather 

 too thin to be regarded as scales, but considering it as such 

 the species would be associated with grijfithi, which struc- 

 turally it is certainly very close to, but the elytra of that 

 species are certainly squamose, and the abdomen of the male 

 is not quite the same; the colour is probably not to be relied 

 upon, but the three specimens before me all have green elytra, 

 and those of grijfithi are not at all green. On the female 

 the upper-surface is without the brassy gloss, the under- 

 surface of one male is mostly bronzy; parts of the first and 

 of the fifth and sixth joints of antennae and the v/hole of 

 the second to fourth are reddish, the apical joint of each 

 palpus is infuscated, the femora are usually deeply infuscated 

 in parts, and where darkest they have a metallic gloss; the 

 tarsi are rather deeply infuscated. The males are evidently 

 rather badly abraded, but the female appears to be normally
