with spurs very unequal, the longer fully twice the length of 

 the other; with three oblique ridges, of which the subapical 

 one is very short. Length 2§-3 mm.

 Hughendon (A. M. Lea). Type, 1. 5890. 



In general appearance strikingly close to the following 

 species, but the pygidium is considerably longer and much 

 thinner, the apical portion being almost hair-like. On both 

 specimens in the Museum the greyish pubescence on the elytra 

 forms two rather obscure fasciae : a wide basal one and a 

 fairly wide postmedian one, the latter on one specimen is 

 somewhat advanced along the suture towards the other ; 

 viewed directly from behind, however, both specimens appear 

 to have entirely black elytra. Owing to the black colour of 

 the hind tarsi I cannot see their oblique ridges clearly, but 

 there appear to be two on each of the two basal joints. 



MORDELLISTENA CASTIGATA, n. Sp. 



Black; muzzle, palpi, base of antennae, front legs, and 

 spurs to hind tibiae more or less obscurely reddish or 

 testaceous; each elytron with an obscure, oblique, reddish 

 humeral vitta. With silken-grey pubescence, somewhat varie- 

 gated on elytra. 



Structurally close to the preceding species. Pygidium 

 long and thin. Spurs to hind tibiae very unequal. Length, 

 2J mm. 



Hab. — -Queensland: Mount Tambourine (A. M. Lea). 

 Type (unique), I. 5901. 



I have not been able to see the ridges on the hind legs 

 clearly, but on the tibiae they appear to be three in number, 

 of which only the median one is long and distinct ; there 

 appear to be two ridges on the basal joint of the tarsi, and 

 one on the second. The pubescence on the elytra is very 

 similar to that of the preceding species, but the fasciate 

 markings are less sharply denned; the basal one almost 

 conceals the humeral vittae, but these are very conspicuous 

 from some directions. 



MORDELLISTENA CONCINNA, n. Sp. 



PI. xv., fig. 118. 



Black ; tip of muzzle, parts of abdomen, antennae, palpi, 

 four front legs, and parts of others more or less reddish, 

 each shoulder with a conspicuous, oblique, flavous vitta. 



Structurally close to the preceding species. Hind tibiae 

 with three oblique ridges, of which the subapical one is very 

 short; basal joint of hind tarsi with three ridges, of which 

 one is very feeble, second joint with one distinct ridge (or
