concealed by the fascicles ; al)()ut scutellar re*;ion with an obtuse 

 elevation on each side, each shoulder from above appearing as a 

 raised, narrow, curved epaulette, at its tip almost meeting a strong 

 projection from the side ; ))et\veen each epaulette and the middle 

 is a large obtusely tiiangula!' elevation, strongly elevated to its tip. 

 In parts shagreened and towards apex with small (setiferous) granules. 

 Epipleurae with dis.tinct striae converging to subhumeral slit, the 

 upper parts polished and Avithout striae. Under surface shagreened 

 and in places wdth irregular punctures. Prosternum with a narrow 

 deep stria, commencing close to each coxa, and curved round so as to 

 terminate at the extreme base at the shoulder. Metostn'uum with a 

 narrow median line. Legs long and thin. Length 4^ mm. 



Hah. — ^New South Wales : Sydney (type in Macleay Museum). 



A large species very unlike any previously described ; the strongly 

 raised prothoracic margins cause the disc to appear concave. 



The fascicles on each elytron are four in number, two are directed 

 forwards and two backwards, so that they meet or irregularly cross 

 at their tips : the outer are smaller than the inner ones, and each is 

 separated from its fellow by a distinct gap. The legs are all longer 

 than the entire body, the hind pair being the longest ; the tibiae are 

 not strongly inflated or angular, but the front pair are somewhat 

 dilated on each side of the tarsal groove. The front femora are too 

 long to be received into the (rather shallow) prothoracic grooves. 



I have not attempted to manipulate the antennae of the type, as 

 they are completely fitted into their receptacles ; the first joint 

 appears large and about twice as long as its greatest width ; the 

 club is only partly concealed, and apparently can be extruded even 

 when the first joint is at rest. 



('Jihitni/ihtpsis ertatnmmae, n.sp. 



Black ; appendages chestnut-red. With a few short pale stiff setae 

 scattered about ; a small and somewhat golden fascicle or pubescent 

 membrane overhanging each depression towards the base. 



Head somewhat rounded ; with large, round, shallow punctures 

 or areolets. Antennae large, first joint with similar punctures or 

 areolets to those of head, curved, its outer edge somewhat grooved, 

 club subcylindrical, lightly curved, almost as large as first ; inter- 

 mediate joints combined much shorter than first, or club. Prnthorar. 

 moderately transverse, sides incurved to middle ; margins not nar- 

 rowly elevate-d, but apex gently raised, disc convex ; with punctures 

 or areolets as on head. Elytra about as long as wide; towards base 

 with a large depression, which towards each side becomes vaulted 

 and does not touch the sides, about base with a feeble elevation on 

 each side ; shoulders raised into feeble epaulettes, each marked off
