ous, minute puiictures, and some slightly larger but still small 

 ones. Elytra with regular rows of fairly large punctures; the 

 interstices with very small ones. Intercoxal process of jjro- 

 stenium rather narrowly elevated. Basal lamelliK of abdorneii 

 large, and rounded posteriorly. Length, 3 mm. 



J/ab. — Victoria : Mount Buffalo (H. J. Carter). 



The general outlines are much as those of G. bJackbn nii, but 

 the abdominal lamelhe are very different. The front coxal 

 ra\ ities are apparently open behind, but the type, being unique, 

 has not been broken to make sure of this. 



Geomela nobilis, n.sp. 



Dark metallic blue, with a purplish gloss : undersurface, 

 femora, and antennie purple, scutellum bronzy. 



Head with minute punctures, and with some larger ones about 

 eyes and on clypeus. Eyes more transverse than usual. An- 

 tennae moderately long, third joint as long as fourth and fifth 

 combined, seventh lightly transverse, the four following ones 

 somewhat wider. Prothora.r about thrice as wide as long; with 

 numerous small but distinct punctures, and a few of larger size. 

 Elytra \\\t\\ rows of not very large but sharply defined punctures; 

 the intei'stices with sparse, and rather minute ones. Intercoxal 

 process of prosternunt wedge-shaped. Basal lamellae of abdomm 

 large, rounded posteriorly, bronzy and shagreened. 'Tibur wide, 

 incur^•ed near apex, basal joint of tarsi strongly inflated. Length, 

 5 mm.

The largest and most beautifully coloured of the genus. The 

 t}pe, being unique, has not been broken to make sure of the 

 front coxal cavities, but they appear to be rather widely open. 

 The general outlines are much as those of G. blackbami, but the 

 eyes, when seen from the side, appear to be fully four times as 

 wide as long. The clypeal suture is feebly defined, Ijut the 

 clypeus itself, owing to its deeper colour and larger punctures, is 

 very conspicuous. The abdominal lamellae are larger than in any 

 other species of the genus. The type, judged by the tarsi, is 

 a male.
