given, it is presumably the type; there are also two co-type 

 females in the South Australian Museum. Its antennae bave- 

 the joints swollen after the second, and after the sixth con- 

 spicuously decrease in width with the apical joint pointed. 

 The palpi are also peculiar and somewhat as figured, but as 

 certain of the parts appear to be adjustable they look different 

 from different points of view, and on different specimens. The 

 male has antennae with the third joint wider than the second, 

 but not to such a great extent as in the female, and the joints- 

 rapidly decrease in size to the sixth, which is only about one- 

 third the size of the second, the five following joints are very 

 thin. The length ranges from 12 to 22 mm. Three other- 

 specimens in the National Museum were taken out of piles 

 in the Moe River, at Yarragon, by Mr. W. Kershaw. 



Atractocerus tasmaniensis, n. sp. 

 PI. xii., fig. 4. 



<3 . Black; abdomen with a purplish gloss. In places 

 (including eyes) with short and more or less upright setae 

 or pubescence. 



Head rounded ; densely granulate-punctate ; with a con- 

 spicuous median carina the length of eyes. Eyes large, fairly 

 close together in front. Antennae short, first joint moderately 

 large, second subglobular, third shorter but a trifle wider 

 than second, fourth to sixth rapidly decreasing in size, 

 seventh to eleventh thin. Prothorax longer than wide, widest 

 near apex, with a deep median groove; with dense and 

 sharply-defined punctures on sides, becoming sparser towards 

 middle. Elytra almost as long as head and prothorax com- 

 bined ; finely shagreened, but about base with distinct 

 punctures. Abdomen long, thin, and parallel-sided. Front 

 legs rather short, the others long and thin. Length, 14-16 mm. 



Hah. — Tasmania: Triabunna (G. H. Hardy). Type, 

 I. 6740. 



The smallest Australian species of the genus, and readily 

 distinguished from the others by its carinated head. The 

 palpi are of remarkable shape, but I have been unable to see 

 them very clearly. The three Australian species may be thus 

 tabulated : — 



Eyes practically touching kreuslerae 



Eyes moderately separated. 



Head not carinated victoriensis 



Head longitudinally carinated tasmaniensis 



Lymexylon australe, Er. 

 L. adelaidae, Blackb. 

 The type of australe was described as being black with 

 piceous legs, and four Tasmanian specimens before me agree
