? . Mandibles rather long, acute at the apex ; clypeus 

 transverse, without a carina. Head strongly but not very 

 closely punctured, much broader than the thorax, nearly 

 twice as broad as long, rounded at the posterior angles. 

 Pronotum fully twice as broad as long, the sides parallel, 

 finely and closely punctured; scutelluni more strongly and 

 sparsely punctured, much narrower than the pronotunj ; 

 median segment no longer than the scutellum, finely and 

 not very closely punctured. First dorsal segment trans- 

 versely rugose, with a deep transverse groove between the 

 carinas at the apex ; second dorsal segment with five strong 

 transverse carinas, including the raised apical margin ; 

 segujcnts 3-5 shining and sparsely punctured ; fifth ventral 

 segment coarsely rugose. Pygidium oblique, the dorsal 

 plate triangular, narrow at the base, the surface rugose ; the 

 ventral plate much longer than the dorsal and very broadly 

 rounded at the apex. Tarsi normal. 



Hab. Dorrigo, New South Wales {R. J. Tillyard) ; 

 November. 



This species can only be placed provisionally in Lepto- 

 tliytmus, the male having no flattened plate on the seventh 

 dorsal segment and the pygidium of the female being 

 narrowed at the base.

S . Clypeus closely punctured, convex, broadly and 

 shallowly emarginate at the apex, the angles of the emargi- 

 uation produced into short spines. Head, thorax, and abdo- 

 men closely punctured ; antenuse shorter than the thorax 

 and median segment combined, slightly narrowed to the 

 apex, the apical joints very feebly arcuate beneath. Inter- 

 antenual carina almost transverse, a low frontal carina 

 almost reaching the anterior ocellus. Anterior margin of 

 the pronotum transverse, the angles not prominent. Dorsal 

 surface of the median segment as long as the scutellum, the 

 posterior slope steep. Abdomen elongate ; the segments 

 moderately constricted at the base ; sixth ventral segment 

 with a very short blunt spine on each side at the apical
