There are some very small ])unetures on the protlioi'ax and elytra, 

 but thev are almost eoneealed by the elotliimi'. The ai)ieal sejrment 

 of the abdoujen (on five specimens before nie, probaljly all males) 

 is large, with its hind margin semicircular, so that the three preced- 

 ing segments are conspicuously narrowed across their middle. The 

 middle trochanters each have a small acute tooth, projecting inwards 

 and slightly forwards, but owing to its position it is not easily seen.

There is a specimen of this species in the Macleay Museum from 

 Rope's Creek, and Or. Ferguson has two from the Blue Mountains. 1

Two specimens from South Australia, in the Jiritish Museum, belong 

 to this species but differ from the types in having the dark markings 

 considerably reduced in intensity ; this, however, is a common varia- 

 tion between Australian and Tasnianian specimens. 



A third from Victoria labelled ''Kin(/i?" in Dr. Sharp's writing 

 also belongs to the same species and has the markings still more 

 reduced. The species, apart froin markings, may be readily distin- 

 guished from Kingi, by its femora beine much less clavate ; the 

 clothing and antennae are also different.

Pale reddish castaneous. ayipendages slightly paler. With pale, and, 

 for the genus, long pubescence. 



Head with outline continuous with that of prothorax, about twice 

 as wide as long. Prothorar rather strongly convex, about once and 

 one-half as wide as hmg, sides strongly rounded, hind ang-les produced 

 backwards to clasp elytra. Elytra about as long as prothorax. and a.t 

 base not as wide, gently decreasing in width to apex, which is widely 

 rounded. Intercoxal process of pi-i internum moderately notched at 

 apex. Femora very flat and compressed. Length, f mm.

 Stenamma longireps (A. M. Lea). 



In size resembling R. ovafa, but readily distinguished from all 

 others of the genus by its comparatively long pubescence ; under a 

 compound power the hairs look like coarse bristles. With u Cod-
