Australian Cistelidae. 103 



and Till, with rather large conical tubercles placed widely apart, 

 each bearing a short, upright hair, a few irregular smaller 

 tubercles at apex outside the 7th interval. Sternum finely punctate, 

 abdomen almost smooth, or very finely striolate. Legs long, femora 

 tumid, fore and mid tibiae with sharp tooth on the inside at 

 middle, all tibiae curved ami somewhat flattened, posterior tibiae 

 of r? enlarged, flattened and hollowed (as in Alcmeonis, but more 

 so). Tarsi bilamellate on four anterior, unilamellate on posterior 

 feet . 



Dimensions. — 1) x 2.8 mm. 



Habitat. — Perth (H. Giles and the author). Champion Bay 

 (Duboulay, Brit. Mus. coll.). 



Three specimens examined, all apparently $ of which one was 

 taken by the author in a rotten " Nuytsia " trunk at South Perth. 

 The British Museum specimen is apparently immature, and reddish- 

 brown in colour, but being glued to a card I have not examined 

 the last segment of abdomen, the other two show the distinct for- 

 cipital process. The special elongate elliptic form, sculpture and 

 tibial characters seem sufficient to separate this and the suceeed- 

 ign species generally from Melaps. Type in the author's coll. 



Notocistela pustulatus, n. sp. 



Very similar to the preceding in form, but differing essentially 

 in the following : — Elytra reddish-brown, upper surface and legs 

 thickly clothed with long, upright red hairs. Elytra with all 

 intervals more closely studded with smaller, less raised setiferous 

 pustules, these more elevated towards apex. Tibial characters very 

 much as in X . tibialis, but less accentuated, especially in the pos- 

 terior tibial characters. Rest as in .V. tiJiinlis. 



Dimensions. — 7.5-!) x 2.5-2.8 mm. 



Habitat.— Shark Bay (Blackburn coll.. South Aus. Mus.). Hoe- 

 buck Bay (Melbourne Mus.). Hermannsburg, Cent. Aus. (H. J. 

 Hillier, Brit. Mus. coll.). 



Three specimens examined. 2 cf, the 3rd specimen (Brit. Mus. 

 coll.), shows a small tooth on the fore and mid tibiae, but is without 

 the enlargement of " hollowing out " of the posterior tibiae. The 

 differences between this sp. and X . tibialis are constant, and too 

 distinctive to allow it to be treated as a ear. Type cf in South 

 Aus. Mus., $ in Brit. Mus.
