rounded on sides, less produced at apex, without humeral 

 denticle at base; sculpture similar. Beneath, convex; basal 

 segments not flattened, obscurely rugulose, with minute trans- 

 verse scratches at sides of basal segments. Tibiae lighter, with 

 long setae beneath but without granules. Dim. — Male, female, 

 23 X 9 mm. 



Hab. — Western Australia: Kookynie (types), Kalgoorlie, 

 Cue (W. H. Brown). In the Museum collection from Cue, 

 also from Central Australia (Elder Exped.) and Coolgardie 

 (Blackburn's collection). A male in the British Museum is 

 from Hermannsburg, Central Australia (H. J. Hillier). 

 Type in author's collection. 



Among described species of Molochtus the present one may 

 be readily identified by the small bidentate supra-ocular crests. 

 Another, undescribed, species in my collection has similar 

 crests, but is a much smaller insect, and differs in other 

 respects. One of the female specimens from Cue in my 

 collection shows whitish squames forming feeble maculae, on 

 the sides and on the apical declivity, and also present on the 

 legs. 



A female collected by Capt. S. A. White at Fincke 

 River, MacDonnell Ranges, perhaps represents a variety of 

 this species. It is smaller (18 x 7 mm.), with even more 

 obliterate elytral sculpture ; the rostrum also is more shallowly- 

 excavate, and has a narrow, impressed, median line. It agrees 

 fairly well with a male in my own collection from the Ash- 

 burton River, Western Australia, but more specimens are 

 necessary to decide whether the form is a subspecific one or 

 merely due to individual variation. 



CUBICORRHYNCHUS CURVIPES, n. Sp. 



d" . In general appearance close to C . maculatus, Macl. 

 Black; densely clothed with dark-greyish squames, the pro- 

 thorax with three or four whitish spots, and the elytra 

 obscurely maculate with white; the apical portion of the 

 femora and the tibiae with dense white clothing; setae light 

 coloured. 



Rostrum gently concave, the sides hardly raised ; with 

 rather coarse punctures; separated from the head, above, by 

 a distinct, impressed, transverse line, not reaching to the 

 sides. Head flattened in front, with scattered, umbilicate 

 granules, strigose between; the upper part of the head finely^ 

 transversely strigulose ; supra-ocular crests rather short but 

 distinct, projecting almost at right angles to the surface. 

 Prothorax (3x35 mm.) with distinct subapical transverse 

 impression, and a rather deeply-impressed median line, deepest 

 in front of middle, but not reaching apex or base; lateral
