Hah. — South Australia: Ardrossaii (J. G. O. Tepper).. 

 Type, I. 1322. 



The apex of each of the front tibiae is supplied with a 

 curious red process, appearing like a rounded plate on its- 

 upper-surface, and forming the apical hook on its lower- 

 surface. The tibiae are somewhat as in a'picatus, but in that 

 species the incurvature is confined to the upper-surface ; in 

 the present species the whole tibia is bent downwards at its 

 middle. The apex of the rostrum is coarsely punctured, but 

 the punctures are usually concealed. There are nine speci- 

 mens under examination, two labelled Ardrossan, but the 

 others without locality labels. They were apparently all 

 taken many years ago, and all are more or less dingy; but 

 this dingy appearance may be natural. The surface is every- 

 where covered with a dingy-greyish or muddy-brown crust, 

 possibly of a mealy nature, upon which chloroform has no 

 apparent action. The darker scales are usually, but not 

 always, thinner than the paler ones. 



Decilaus humeralis, n. sp. 



Black; antennae claws and tibial hooks of a dingy-red. 

 Moderately clothed with fawn-coloured scales; much denser 

 on tibiae than elsewhere. 



Head and rostrum apparently much as in preceding 

 species; but club stouter and abruptly wider than preceding 

 joints. Prothorax as long as wide, sides strongly rounded, 

 base truncate; with dense, coarse punctures, in places feebly 

 confluent; with a narrow, continuous median carina. Elytra 

 oblong-ovate, shoulders distinctly produced and clasping sides 

 of prothorax; with rows of large, deep, and often angular 

 punctures. Two basal segments of abdomen large, with very 

 coarse punctures, especially on the second; three apical seg- 

 ments conspicuously depressed below the others; apical one 

 with dense punctures and a subapical fovea. Legs short and 

 stout. Length, 8J mm. 



Hah. — Australia (old collection). Type, I. 1323. 



The type is covered with the same muddy-looking 

 indumentum as are the specimens of the preceding species; 

 the scales may normally be paler than as described, as where- 

 they were covered up (at the base of the head) they are of 

 a rather pale stramineous. The front tibiae are armed much 

 as in the preceding species, but they are not bent inwards. 

 It differs also in its larger elytral punctures and conspicuous 

 prothoracic carina. The type was probably from South . 

 Australia.
