rounded; punctures dense, clearly defined, and not very- 

 large. Elytra elongate-cordate, sides moderatel}^ rounded; 

 with rows of large suboblong punctures, becoming smaller 

 posteriorly; interstices acutely ridged for most of their 

 lengths, but the first only on posterior declivity, with a row 

 -of distinct punctures on each side of each ridge. Under- 

 ^urface with dense and coarse punctures; basal segment of 

 abdomen depressed in middle of base, apical segment with a 

 wide, shallow impression. Femora stout, strongly dentate. 

 Length, 4 mm. 



Hah, — Queensland: Townsville (H. H. D. Griffith from 

 F. P. Dodd). 



A black species of medium size but readily distinguished 

 by the conspicuous fascicles on the trochant'ers ; these, how- 

 ever, may be sexual, as both the specimens before me appear 

 to be males. The front trochanters have each one strong seta, 

 and a similar seta is on each side of the subapical abdominal 

 impression. 



Melanterius legitimus, Lea. 



Two specimens from Mount Wellington (i^) probably 

 belong to this species, but differ from the type in having the 

 basal two-thirds of the rostrum tricarinate. On the type the 

 punctures are more or less in rows, but, except for the median 

 carina, the spaces separating the rows are not distinctly 

 ■carinated. 



Melanterius congruus. Lea. 



This species has the second abdominal segment fairly large 

 in comparison with most species of Diefhum, and the femora 

 feebly grooved, and so was referred to Melanterius, despite the 

 density of its clothing. The type is a male, and its front tibiae 

 are rather strongly curved, the apical spur is of normal appear- 

 ance, but behind it the apex of the tibia has two ridges (con- 

 verging to the spur), between which the tarsus is placed. The 

 hind tibiae are bisinuate, but the apical sinus is short, so that 

 from some directions it appears almost like a notch, the apical 

 spur is stouter and larger than usual, and has a small supple- 

 mentary tooth or granule on one of its faces. From some direc- 

 tions the basal segment of abdomen appears to have a large 

 depression, of such a shape that its middle runs out narrowly 

 to the apex of the segment. A second male agrees in size and 

 in all structural details with the type, but the base of its el3''tra 

 lias indistinct spots of brownish scales, and about the middle 

 there are some faint whitish spots. 



A small (2-^ mm.) male from Sydney has the front tibiae 

 rather more strongly curved, with a stronger spur, the hind 



(17) Now first recorded for Tasmania.
