the claws; each of these has a very small and acute tooth near 

 the base and at the extreme base a gentle swelling; in Rhopaea 

 the tooth is considerably larger and more distant from the base. 

 At first glance it has the appearance as of being allied to 

 Liparetrus and Gomophorus. The spurs to the hind tibiae are 

 acute and almost evenly decrease in width from the base to the 

 apex. 



MlCRORHOPAEA FLAYIPEXXIS, ll.Sp. 



cf Black ; elytra and antennae flavous, basal joint of the lather 

 darker, palpi and tarsi of a more or less dingy red. Elytra 

 with sparse, short, depressed, white setae; rest of upper sur- 

 face, under surface and legs with rather dense, long, white hair. 



Head (including clypeus) with coarse, crowded punctures. 

 Antennae with basal joint slightly longer than two following 

 combined, second narrow at base and suddenly dilated at apex; 

 rami of the flabellum of equal length and slightly longer than 

 clypeus is wide. Prothorax about twice as wide as long, front 

 angles almost completely rounded off, hind ones obtuse; with 

 large and coarse punctures, but leaving an impunctate median 

 line on basal half. Scutellum with coarse punctures at base, 

 apex shining and impunctate. Elytra with sides gently rounded, 

 each obliquely truncated at apex; without striae except one 

 with coarse punctures on each side of suture; punctures rather 

 large, but not so crowded (although in places confluent) as _on 

 prothorax. Pygidium with dense, more or less concealed punc- 

 tures. Apical tooth of front tibiae long and acute, second 

 acutely triangular, third small. Length, 9.5 mm. 



Hab. — Northern Territory: Darwin (N. Davies). 



The colour, clothing, and beautiful fan-like antennae render 

 this species an extremely distinct one; it is the smallest Aus- 

 tralian member of its subtribe. 



Engyops castaneus, n.sp. 



Bright reddish-eastaneous. A fringe of long hairs on each 

 side of prothorax and elytra, rest of upper surface glabrous; 

 pygidium with a conspicuous fringe; under surface and legs 

 sparsely and irregularly clothed. 



Head with sparse and rather small punctures between eyes. 

 Clypeus semicircular, margins moderately upturned, and near 

 base suddenly deflected outwards, hind suture curved to middle:
