front, with margins lightly upturned ; hind suture con- 

 spicuous, outcurved in front, incurved at sides. Labrum on 

 the same plane as clypeus and rather more strongly upcurved 

 in front; with an irregular row of strong punctures in front. 

 Proth&rax strongly convex, sides strongly rounded, hind 

 angles widely rounded off; along middle and across a fairly 

 wide space near base impunctate, elsewhere with rather small 

 but sharply-defined punctures, irregularly distributed and 

 nowhere crowded. Scutellum semicircular, with rather 

 numerous punctures. Elytra with shoulders, sides, and apex 

 rounded; sutural stria distinct, with several feeble geminate 

 striae; much of the surface finely wrinkled, and with small 

 scattered punctures. Pygidium impunctate along middle, 

 finely asperate elsewhere. Legs short and thick; front tibiae 

 strongly bidentate, hind pair about as long as the apical width. 

 Length, 25 mm. 



Hab. — Australia (J. S. Clark). Type (unique), I. 10791. 



The species has the robust build of many female Dynas- 

 tides, to which subfamily at first glance it appears to belong; 

 but the clypeus, labrum, tibiae, etc., are in exact agreement 

 with Systellopus obtusus; from which it differs in its high 

 polish and much greater size, characters which also distinguish 

 it from the description of validus. Both antennae and five 

 of the tarsi have been broken, but the species is so distinct 

 that I have not hesitated to describe the type. It was sent 

 by Mr. Clark as from Chillagoe in Queensland, but as he had 

 an accident with a box and some labels were mixed, the locality 

 may be doubtful, and the specimen may have really been 

 taken in Western Australia. 



Haplonycha marginipennis, n. sp. 

 PI. xxvi., fig. 54. 



Dark castaneous-brown with an opalescent gloss ; head 

 and parts of legs black. Head with fairly numerous long 

 hairs between eyes, and very numerous on two basal joints 

 of antennae, prothorax completely fringed with long hairs, 

 narrowly on sides and base, widely in front ; sterna densely 

 clothed with dark hair, in parts almost sooty, pygidium 

 sparsely clothed and with a thin marginal fringe ; elytra with 

 two fringes. 



Head smooth at base, with crowded and coarse punctures 

 elsewhere. Clypeus with sides strongly narrowed to the front, 

 which is strongly upturned ; front face with dense punctures. 

 Antennae nine-, club three-jointed; fourth joint slightly 

 longer than third and fifth. Penultimate joint of maxillary 

 palpi distinctly longer than antepenultimate, and slightly 

 longer than apical. Prothorax widely transverse, sides
