SCIMBALIUM PICEUM, Macl. 



6^. ferrugineum, Fvl. 

 A specimen, from Northern Queensland, identified by Blackburn as S. 

 ferrugineum, and agreeing with the description, was compared and agrees with 

 the type of Lathrobium piceiim. As its front tarsi are only moderately dilated 

 and basal joint of hind tarsi distinctly longer than the second, it is quite 

 evidently a Scimhaliuui. 



SCIMBALIUM RUFUM, Fvl. 



Two. specimens of an apterous species, from Melbourne, agree well with the 

 description of this species ; at first glance they are strikingly like Lathrobium 

 adclaidae, but the antennae are longer, elytra distinctly shorter, front tarsi less 

 dilated, and basal joint of hind tarsi as long as the two following combined. 



Scimbalium pallidulum, n. sp. 

 Pale castaneous ; antennae, palpi, and legs paler, head slightly inf uscated. 

 With fairly numerous dark hairs scattered about; abdomen with rather dense 

 ashen pubescence, head and elytra more sparsely clothed, prothorax with hairs 

 but hardly any pubescence. 



Head between antennae and neck about as long as wide ; with numerous, 

 fairly large, sharply-defined punctures, becoming smaller and more crowded in 

 hind angles (which are strongly rounded). Antennae thin, passing base of pro- 

 thorax, first joint almost as long as second and third combined, third distinctly 

 longer than second and fourth, the others to tenth gradually decreasing in 

 length, • but all distinctly longer than wide. Prothorax distinctly longer 

 than wide, almost parallel-sided, except that the angles are rounded ; 

 with rather dense punctures, smaller than on head, but absent from 

 a rather narrow median line. Elytra distinctly longer and wider than 

 prothorax, sides slightly dilated posteriorly ; with rather dense and asperate 

 but sharply-defined punctures, nowhere seriate in arrangement. Legs rather 

 long;- front femora slightly dentate; front tibiae notched at about basal third; 

 front tarsi with four basal joints almost as wide as apex of tibiae, the other tarsi 

 longer and thinner. Length, 6-7 mm. 



Hab. — Northern Territory: Daly River (H. Wesselman), Adelaide River 

 (British Museum); North-western Australia: Derby (W. D. Dodd and Dr. A. 

 M. Morgan). Type, L 12645. 



In appearance close to 6". semifmnatum, but head and abdomen paler, 

 antennae and prothorax longer, and elytral punctures somewhat different. The 

 colour and size would do fairly well for 5". opacuhim, but punctures of head 

 and prothorax certainly dififer from the description; in Fauvel's table '^-•'' the 

 prothorax and elytra are noted as having very dense obsolete punctures ; on the 

 present species the elytral punctures are dense and rather small, although quite 

 distinct, on the prothorax they are sparser, somewhat larger, and quite sharply 

 defined, but absent from a median line. The prothorax is of a brighter colour 

 than the rest of the upper-surface. The mandibles are stout and strongly 

 dentate, the front tooth larger than the others. The tip of the abdomen is 

 triangularly notched in the male, and the front femora are rather more strongly 

 dentate than in the female. 



Scimbalium micropterum, n. sp. 



9 ■ Black ; prothorax and legs dark red, palpi and tarsi paler, parts of 

 antennae reddish, but mostly deeply infuscated. With fairly numerous dark 

 hairs, elytra and abdomen with dark pubescence, rather dense on the latter.
