with very dense and minute punctures, 'i ip of abdomen notched on both sur- 

 faces. Front femora stout and edentate ; front tibiae notched at about basal 

 third ; front tarsi with four basal joints slightly inflated (about twice the width 

 of the others), basal joint of hind tarsi slightly longer than the two following 

 combined. Length, 4-4.25 mm. 



9 • Differs in having the head and prothorax slightly narrower, legs and 

 antennae slightly shorter and abdomen not notched. 



Hah. — Tasmania: Hobart from a tussock, Nubeena, Huon River (A. M. 

 Lea); Victoria: Warburton in August (F. E. Wilson). 



A dingy subopaque species, at first glance apparently belonging to M. lindi, 

 or M. tristis, but elytra decidedly smaller (at most as long as wide, they are very 

 little longer than the prothorax and scarcely as wide as its widest part) ; on 

 I'uidi and tristis they are decidedly longer than wide, distinctly longer and con- 

 spicuously wider than the prothorax. I have made sure that wings are folded 

 beneath the elytra. Of the six specimens before me most have the prothorax 

 as dark as the head, but on one specimen it is obscurely reddish ; the hind 

 femora and tibiae (except the knees) are usually darker than the rest of the legs. 



A male, taken from flood debris at Latrobe, appears to belong to this species, 

 l)ut differs in having the elytra flavous, except that their basal third is rather 

 deeply infuscated.

9 ■ Of a dingy opaque-brown ; mandibles, palpi, and legs paler. With 

 rather long, straggling, dark hairs, elytra and abdomen with dense ashen 

 pubescence, becoming very inconspicuous on head and prothorax. 



Head strongly transverse between front of eyes and neck, hind angles feebly 

 rounded off; punctures minute and very dense. Mandibles long, acute, and 

 strongly dentate. Antennae slightly passing base of prothorax, first joint as 

 long as second and third combined, second slightly wider and very slightly 

 shorter than third, ninth and tenth slightly transverse. Prothorax distinctly 

 wider than long, rather closely applied to and slightly wider than head, front 

 angles almost square, hind ones strongly rounded, with a very narrow but con- 

 tinuous median line ; punctures as on head. Elytra at base slightly wider than 

 widest part of prothorax, and very feebly dilated to near apex, at least half as 

 long again as the prothorax, and with somewhat similar punctures. Abdomen 

 with dense and very minute punctures. Front femora stout and edentate, front 

 tarsi slightly wider and shorter than the others. Length, 4-4.25 mm. 



Hab. — Queensland: Cairns district from fallen leaves (A. M. Lea), attached 

 to a sticky seed of Pisonia brunoniana (F. P. Dodd). Type, L 12635. 



An unusually flat opaque species, about the size of M. ochraceus, but 

 otherwise very different; it perhaps belongs to the subgenus Charichirus. The 

 type has the head slightly paler than the prothorax, and the front angles of pro- 

 thorax and base of elytra paler than the adjacent parts, but the two shades of 

 colour not sharply limited. The specimen from Pisonia seed has the upper- 

 surface almost black, except that the shoulders are inconspicuously reddish, and 

 the legs and other appendages of a dingy red ; on each specimen the apex of 

 the (apparent) fifth segment of abdomen is obscurely pale. On both specimens 

 there are four teeth on the right mandible and three on the left. From some 

 directions the head, prothorax. elytra, and metasternum appear to be very 

 densely and evenly granulate ; the prothorax from some directions appears to 

 have some of the punctures longitudinally confluent. The granulation of the 

 under-surface of the head, including the mentum. is rather more conspicuous 

 than on the upper-surface, the gular suture appears single for its greater extent.
