Hab. — Western Australia: Stirling Ranges. 



The above description is taken from the Macleay Museum specimens, of 

 which there are 2 <? under ,1. masters/, and two 9 under A. posticalis. It is un- 

 certain whether these or the Australian Museum specimens are the actual type?;. 

 There can be no doubt that Macleay was misled by the sreat difference in the sexes, 

 in describing them as two distinct species. 



ACAXTHOLOPHUS GLADIATOR Pasc. 



Pascoe. Joura. Linn. Soc. xii.. 1873, p. ti. plate 11.. tig. 3-3a. 



d'- Black; rather densely clothed with minute sandy squames, somewhat 

 lighter on sides. 



Rostrum widely and shallowly concave, lateral margins hardly raised, rec- 

 tangulate anteriorly; internal ridges short, little ])rominent; basal foveae rather 

 shallow, closed. Head with intercristal ridge low. V-shaped; supraorbital crests 

 short, single, acutely pointed, set at right angles to plane of head. Antennae 

 with first joint of funiele shorter tluni second; club moderately elongate. Thorax 

 with anterior tubercles of submedian row forming a strong securifonn crest pro- 

 jecting over head, followed by a row of 4 large conspicuous tubercles in single 

 series; lateral tubercles comprising a large median spine and a much smaller 

 posterior one. about half its size. El.\i:ra with punctures obsolete, and gi-anules 

 small ; with three rows of spiniform tubercles, first row with 5 — 7. anterior ones 

 small, tlic apical two large and spiniform. ending at declivity; second witli 

 4 — 5. all large, increasing in size to declivity, and ending half way down, with 

 a smaller, acute, preapical tubercle or spine on either side; humeral tubercle 

 large and spiniform; third row with two tubercles only. Ventral surface with 

 punctures obsolete; apical segment slightly rugose at extreme apex. Inter- 

 mediate til)iae witli subapical notch. 



?. More robust with smaller and more numerous olytral tubercles; first row 

 with 10 mostly small, the apical two Large, acute, spines, the last one situated 

 halfway down declivity; second row with 6, not including humeral and preapical. 

 spiniform but shorter than in d"; third with 2; remaining interstices with evidont 

 granules; intermediate tibiae without imtili. Pimeiisions: c?. 18 X 7 unn. ; ?.

If ah. — Western Australia: Mullewa, Cniiderdin. KellerlHirin. 



The specimen- from Ivellerberrin possilily represents a variety, as the api- 

 cal ventral segnumt is set with larger and coarser punctures; Pascoe des<'ril)c.s 

 the abdomen as "spai-se punetato." which corresponds better with the MuUcwa 

 m.alc 



The description of the female is from a specimen taken by Mr. T. Ci. 

 Sloane at f'underdin. neai- KelUrberrin. and probably conspecific with the KeUcr- 

 berrin male; the supraorbital crests in this specimen arc minutely liifid at tlie 

 extreme apex.
