almost regular close to the costae, irregular elsewhere. 

 Pygidium with dense asperate punctures. Front tibiae 

 strongly tridentate, the teeth black-tipped and close together, 

 basal joint of front tarsi about as long as two following 

 combined, claws long, simple, and unequal. Length, 11 mm. 



II ah. — Northern Territory : Melville Island (W. D. 

 Dodd). Type (unique), I. 4854. 



The hairs composing the fringe on the clypeus are all 

 depressed and directed backwards. All the elevated parts of 

 the elytra are distinctly paler than the depressed parts. 



Since the above was written I have examined some speci- 

 mens from the King and Roper Rivers in the National 

 Museum; these vary in length from 10 to 12 mm., and in 

 colour from that of the type to having the upper-surface (the 

 shoulders and subapical callosities excepted) black; two are 

 females and have the larger of the front claws slightly cleft, 

 their colour varies as in the males and the clypeal fringe is 

 much the same. 



Saulostomus mimicus, n. sp. 

 'PL xxvii., figs. 79 and 80. 



d . Bright castaneous, tibial teeth and some marginal 

 parts darker. Under-surface, legs, base of antennae, and 

 ocular canthi, with long, rusty-red hair, pygidium with 

 depressed but long pubescence, and with long straggling hairs, 

 elytra fringed with reddish setae, directed outwards, and 

 with a thin membrane directed downwards. 



Head with sharply-defined and rather sparse punctures 

 about base, becoming rather dense in front, and crowded 

 but less sharply defined on clypeus. Clypeus semicircular, 

 margin moderately upturned in front, less so on sides, hind 

 suture slightly arched, the convex side directed to the front. 

 Antennae ten-, club three- join ted; club long, almost parallel- 

 sided, distinctly longer than front tibiae. Prothorax about 

 thrice as wide as long, sides rather strongly and evenly 

 rounded, not much wider at base than at apex, front angles 

 subacute, hind ones rounded off, all margins narrowly 

 impressed except in middle of base ; punctures of moderate 

 size, sharply impressed and nowhere dense, even on sides, 

 interspersed with numerous minute ones. Scutellum with two 

 kinds of punctures as on prothorax. Elytra with conspicuous, 

 but irregular geminate rows of fairly large punctures, in 

 moderate or feeble striae, the interstices also with rather large 

 punctures, numerous small punctures scattered about. 

 Pygiclium with dense and rather shallow transverse punctures. 

 Front tibiae strongly and acutely tridentate ; claws unequal 

 but simple. Length ( d 1 , 9)> 13-16 mm.
