sent additional specimens from Dorrigo, one of which is a 

 male. It differs from the female in having each of the 

 middle coxae conspicuously armed with an upright, obtusely- 

 pointed ridge ; the basal segment of the abdomen is flat, with 

 the base and sides of the intercoxal process conspicuously 

 elevated, the front tibiae are stronger and more curved, and 

 are conspicuously ciliated; the hind tibiae have their apical 

 three-fifths largely scooped out on the inner side, so that 

 when viewed from most directions each appears moderately 

 curved on the outer side and very strongly on the inner, the 

 scooped-out part commences so suddenly that, from some 

 directions, it appears to start from a subbasal tooth; there 

 are also two contiguous medio-basal f oveae (small but con- 

 spicuous) on the prosternum. The clothing of the fresh 

 specimens is more of a rusty-red than on the types, and the 

 apical slope is rather less uneven. The female could still be 

 assigned to the position given it in the 1914 table of the 

 genus, but the male would be associated with dentipes, from 

 which it differs in its different and more conspicuous dentition 

 of middle coxae and very different hind tibiae ; the hind 

 tibiae of dentipes are very decidedly shorter, more regularly 

 diminish in thickness from the base to the dilated apex, and 

 are rather more strongly and evenly curved; that species also 

 is without medio-basal foveae of the prosternum, and has 

 conspicuous bristles on the metasternum and part of the 

 abdomen. 



Mandalottjs angttstus, Lea. 



On the middle coxae of the type male of this species 

 there is a shining, slightly-elevated ridge ; it is indistinct, 

 from some directions, but fairly distinct from others. 



Mandalotus squamibundus, Lea. 



In the 1914 table of the genus this species was separated 

 from maculatus (from which, however, it differs in many 

 respects) by the absence of pale elytral spots. But Dr. 

 Ferguson has sent eight fresh specimens from Bowen for 

 examination, and nearly all of these have four rather feeble 

 pale spots at the base of the elytra, and a few still more feeble 

 ones scattered about elsewhere. 



Mandalotus nodicollis, Lea. 

 Some specimens of this species from Townsville are 

 evidently in perfect condition, without the muddy crust that 

 usually conceals the clothing. The clothing is very dense, 

 of a light muddy-brown or grey, with numerous pale spots 

 scattered about on the head, prothorax, elytra, and legs; on 

 some specimens the spots have a silvery lustre, or even a
