elytron they are in five irregular rows (the second and third 

 subgeminately arranged). The appearance as of strings of 

 beads on the elytra is rather distinct from some directions, 

 but is interfered with to a certain extent by the scales. The 

 mentum, when viewed perpendicularly, appears like a flat, 

 shining semicircle. 



Maechidius sculptipennis, n. sp. 

 PL xxxvii., fig. 92. 



Blackish; parts of legs obscurely diluted with brown, 

 antennae and palpi somewhat paler. 



Head rather strongly convex, and with coarse crowded 

 punctures, becoming somewhat smaller on clypeus : this deeply 

 notched in front, and with each side strongly trilobed. 

 Prothorax moderately convex, sides strongly rounded and 

 obtusely serrated, base strongly bisinuate, with the hind 

 angles acute, with a vague median depression ; with crowded 

 and large punctures, becoming smaller on sides. Elytra very 

 irregularly sculptured. Front tibiae tridentate, two first 

 teeth large and close together, the third much smaller and 

 almost in the exact middle, hind tibiae obtusely serrated ; 

 basal joint of hind tarsi not much longer than second : each 

 claw with a conspicuous quill. Length, 9^-10 mm. 



Hab. — South Australia: Mount Lofty (S. H. Curnow 

 and A. M. Lea). Type, I. 4811. 



In Blackburn's table would be associated with macleay- 

 anus, which has similarly sculptured head and prothorax, but 

 very different elytra, in many respects it agrees with the 

 description of sexdentatus, but the size is somewhat larger, 

 the lateral projections of the clypeus are too obtuse to be 

 called triangular, and the hind angles of the prothorax are 

 acute and directed slightly outwards. The geminate rows of 

 punctures on the elytra are conspicuous, and each puncture 

 has a distinct shining granule, so that the appearance as of 

 strings of beads is unusually pronounced ; but on each elytron 

 there are three wide, shining interstices, strongly crenulated 

 by the punctures, about half of which are without granules. 

 There are no true granules on the head, but there appear to 

 be numerous ones from certain directions ; the notch in front 

 of the clypeus passes along the lower lip, and terminates on 

 the mentum, which has a distinct median fovea. 



Maechidius insularis, n. sp. 

 PI. xxxvii., fig. 93. 

 Dull-black ; elytra and parts of legs obscurely diluted 

 with red; antennae flavous. Clothed with thin, depressed 

 pale setae.
