reaching base, nor extending down declivity; fifth with tubercles 

 much smaller, about seven in number, closer together about 

 shoulder, becoming more spaced-out and smaller posteriorly; sixth 

 with a row of nine, rather closely set, larger than on fifth, but 

 smaller than on the other interstices. Sides with interstices closely 

 set with small, obtuse tubercles. Beneath, with a median, hirsute 

 vitta extending from metasternum to apex; fifth segment with a 

 subquadrate depression, more or less obscured by the median 

 vitta. Intermediate tibiae with a strong, subapical notch. 



9. Similar to ^, but more robust and ovate; tubercle-index 

 3, 6, 0, 9, 7; beneath, convex, median vitta much less dense, not 

 hirsute, subsetose. Internal tibiae with notch much feebler. 



Dimensions : ^, 14 X 6; 9, 14 x 6-5 mm. 



Hab. — Queensland : Upper Logan River, Warwick. Type in 

 Queensland Museum. 



Several specimens of this species, sent from the Queensland 

 Museum, are under examination. The type is an exceptionally 

 well clothed specimen, most of the others being mote or less 

 abraded. The tubercles on the elytra vary in number, and are 

 sometimes present on the declivity in the second and third in- 

 terstices and sometimes not. The tubercle-indices of two other 

 females may be given: 9, 5, 6, 1, 11, 8; 9, 6, 6, 3, 8, 11. 



Two males in the National Museum, Melbourne, probably re- 

 present a variety of this species; they are narrower; in one, the 

 fifth interstice has no tubercles, except the humeral one; and, in 

 the other, a few, very small, separated tubercles. They are 

 labelled (1)West Australia. 



The character of the fifth interstice appears to associate this 

 species with S, tuherculosus, rather than with the subcostatus- 

 group, in which the fifth interstice is strongly and closely 

 tuberculate.

This species is almost certainly a true Sclerorinus, and pro- 

 bably a member of Group v. I have seen no insect that I can 

 associate with the name. The intermediate tibiae are notched,
