quite black, but with the sides and suture narrowly diluted 

 with red. 



MORDELLISTENA COELIOXYS, n. sp. 



Castaneous. 



Pygidium long and acute. Antennae long and thin. 

 Hind tibiae with very unequal spurs, the longer more than 

 twice the length of the other; with four oblique black ridges, 

 basal joint of hind tarsi with four, the two following joints 

 each with two ridges. Length, 4-6 mm. 



Hab. — Queensland: Mount Tambourine; New South 

 Wales: Sydney (A. M. Lea). 



In general appearance strikingly close to austrina, but 

 with the ridges on the hind legs different ; the sub-basal ridge 

 on the hind tibiae is very close to the second, and is indistinct 

 from some directions, although sufficiently distinct from others. 

 The pubescence is very similar in colour to the derm on which 

 it rests. On one specimen the sterna and disc of pronotum are 

 obscurely infuscated; the specimen from Sydney is much 

 paler than the others (almost flavous), and was taken from a 

 tussock of grass. 



MORDELLISTENA MULTILINEATA, n. Sp. 



Of a rather dingy castaneous, parts of sterna obscurely 

 infuscated. 



With the general shape of austrina. Pygidium long and 

 acute. Antennae long and thin. Hind tibiae with spurs 

 very unequal, with three oblique black ridges; basal joint of 

 hind tarsi with four, the following with two ridges, the third 

 without any. Length, b\ mm. 



Hab. — New South Wales: Acacia Creek (H. J. Carter). 

 Type (unique), I. 6019. 



The oblique lines on the elytra, if constant, should render 

 the species easy of recognition ; but in any case, the curious 

 disposition of the ridges on the hind legs should be distinctive. 

 The pubescence has mostly a somewhat silken appearance, but 

 on the pronotum three vague dark spots are indicated from 

 certain directions; on each elytron there are four slightly 

 oblique lines on which the pubescence is paler than on the 

 adjoining parts, and as that on the suture is also pale the 

 elytra from directly above have a nine-lined appearance : 

 seen directly from behind, however, the pubescence appears 

 blackish, and the lines are scarcely indicated. 



MORDELLISTENA MELVILLENSIS, n. Sp. 



Piceous-brown or castaneous, some parts obscurely 

 variegated.
