abdomen with apparent sixth and seventh segments triangularly notched to 

 base. Legs not very long, front femora stout and scarcely visibly dentate; 

 front tibiae feebly notched at about one-third from base. Length, 3.75-4 mm. 



9 . Differs in having slightly shorter antennae and legs, and abdomen not 

 notched. 



Hah. — Northern Territory: Oenpelli (P. Cahill) ; Queensland: Cairns dis- 

 trict, to light; New South Wales: Tweed River (A. M. Lea). Type, L 12639, 

 in South Australian Museum ; cotype in National Museum. 



A pale almost opaque species, slightly above the average size of species of 

 this genus and like Domene australiae in miniature, and much like D. microps, 

 but without the remarkable front tibiae of those species. In some respects it 

 apparently resembles S. hlackburni, but the front legs are without conspicuous 

 armature. From the preceding species it differs in being wider, with smaller 

 punctures, especially on the under-surface of head, antennae longer, with the 

 third joint conspicuously longer than second, abdomen no darker than elytra, etc. 

 The punctures are everywhere dense, and too small to be seen clearly under a 

 hand lens. There are remnants of a medio-basal elevation on the prothorax, 

 with a depression on each side of it, but they are so feeble as to be invisible 

 from most directions, and distinct from none.

Domene australiae, Fvl. 



Two specimens (5-6.5 mm.), from New South Wales, that appear to agree 

 with the description of this species, differ from a cotype, and some other 

 Adelaide specimens of D. torrensensis, in having the elytra somewhat shorter, 

 the prothorax flatter, and without a median elevated line. The differences men- 

 tioned are distinct on seven specimens of torrensensis, and two of australiae, 

 but are possibly only of varietal importance ; if synonymous the latter has 

 precedence. A specimen from Oenpelli, in the National Museum, has elytra of 

 the same proportionate length as in torrensensis, but its prothorax is narrower 

 and median line less conspicuous. 



Domene torrensensis, Blackb. 



Mr. H. H. D. Griffith took several specimens of this species during a flood 

 on the Torrens River. Two of them are males, and have on the under-surface 

 of the apparent fourth segment of abdomen a large and almost circular depres- 

 sion, on the following segment there is a wider and almost parallel-sided one, 

 and the following segment is narrowly notched to the base itself.

d . Dark brown ; head still darker, legs paler, mandibles black. Densely 

 clothed with short ashen pubescence, and with a few hairs scattered about. 



Head fairly large and ovate, hind angles strongly rounded, neck very small, 

 antennary tubercles highly polished. Eyes rather small, prominent, and with 

 coarse facets. Antennae rather stout, first joint cylindrical, about as long as 

 second to fourth combined, the following ones to tenth subglobular. Prothorax 

 about as long as head to mandibles, and distinctly narrower, hind angles strongly 

 rounded, apical third triangularly narrowed to neck, with a very narrow median 

 line, slightly elevated above the general surface near base, and with a very nar- 

 rowly impressed line about middle. Elytra slightly wider than head and slightly 

 longer than prothorax. Abdomen with first segment very small, and with a
