differ from the description in having most of the joints of antennae slightly 

 transverse, and the median ones slightly infuscated. 



Scopaeus ctenocryptus, n. sp. 



9. Shining black; mouth parts, mandibles, antennae, palpi, and legs 

 (femora darker) pale brov^n or testaceous. With very short ashen pubescence, 

 denser on abdomen than elsewhere. 



Head ovate, strongly rounded towards base and with a small narrow neck, 

 depressed between antennae. Mandibles strong and acutely dentate. Eyes 

 rather large.. Antennae long, passing base of prothorax, first joint cylindrical, 

 as long as second and third combined, third distinctly longer than second and 

 fourth, the others gradually decreasing in length to tenth, but none transverse. 

 Prothorax dilated from base to slightly in advance of middle, and then strongly 

 narrowed to apex, which is the same width as the neck, a short median carina 

 at the base, on each side of which is a shallow depression. Elytra much wider 

 than prothorax, and slightly longer than prothorax and neck combined, angles 

 strongly, the sides slightly rounded. Legs rather long, femora edentate. 

 Length, 3.75-4 mm. 



Hah. — Queensland: Mulgrave River (H. Hacker). 



A black species, but differs from 6". digitalis in being larger, head of some- 

 what different shape, with larger eyes, antennae much longer, with no joints 

 transverse and at least five decidedly pale ; the basal half of the antennae is 

 distinctly darker than the apical half. The under-surface, especially of the 

 abdomen, is not as dark as the upper-surface. The upper-surface of the 

 abdomen is less shining than the other parts, owing to its denser clothing. The 

 punctures are very minute, scarcely visible under a hand lens. There is a 

 notch (invisible from many directions) at about the basal third of the front 

 tibiae, and this is supplied with a comb of numerous small teeth, but the comb 

 is so placed as to be visible Avith difficulty even under a compound power; 

 under a hand lens it appears as an oblique ridge. 



Scopaeus moerens, n. sp. 



c • Black ; tarsi and parts of palpi obscurely paler. 



Head between antennae and neck about as long as wide, hind angles gently 

 rounded off. Antennae scarcely passing base of prothorax. first joint as long 

 as second and third combined, fifth to tenth transverse. Prothorax distinctly 

 longer than wide, apical third strongly narrowed to neck, a small median eleva- 

 tion at base. Elytra conspicuously wider and longer than prothorax, parallel- 

 sided except at angles. Under-surface of abdomen notched in middle of apex 

 of apparent sixth and seventh segments. Legs not very long, femora stout, 

 the front ones feebly dentate ; front tibiae notched and with a small comb at 

 about basal third. Length, 2.25-2.5 mm. 



9 • Differs in having the head slightly smaller, antennae and legs slightly 

 shorter, and abdomen not notched. 



Hah. — Western Australia: Newcastle, Darling Ranges, and Pinjarrah (A. 

 M. Lea). 



A very small species, in general appearance close to 5". lafchricola, but 

 smaller and darker; 5. digitalis is larger, with conspicuously pale tarsi. On 

 some specimens the front legs are of a dingy brown, and on such the labial 

 palpi are flavous ; but at first glance the species appears to be entirely black. 

 The head and prothorax are more shining than the other parts, but this is due 

 to the very fine pubescence being sparser there than elsewhere. The punctures 

 of the upper-surface are very dense and small, scarcely visible under a hand lens.
