some of the specimens. The scape is long and relatively slender, and the fii-st 

 joint of the funicle approximately equal to the second. The supraorbital crests 

 have the middle branch small and often reduced to a small spicule or even 

 absent ; the intereristal ridge curves l)ackwards into the base of the posterior 

 ramus, the anterior arising at a distinct angle.

ACAXTHOLOPHUS FRANKLIXEXSIS Blackb. 



Blackburn, Trans. Roy. Soc- S. Aust. 1890, p. 92. 



Under this species I place specimens of a species of Acantholophus from Yee- 

 lanna. South Australia; the type itself I have not seen, and do not know of its 

 whereabouts: Blackbuni stated that it \va« in the collection of Mr. .J. Andereon, of 

 Port Lincoln. 



While closely allied to A. tiivetirittatus Blackb., the species differs in having 

 the basal tubercles of the first row smaller and closer together, there being 8 — 9 

 tubercles in the row, with only the last 3 acutely spiniform, whereas in ,4. wiver- 

 vittatiis there are 5 — 6 and the basal ones, though smaller, are conical; the 

 granules on the other interstices are also larger. The antennae are not so slender 

 us in A. niveovittahils. and the supraorbital crests have the middle branch longer 

 and more developed. 



j{ah. — South Australia: Franklin Harbour, Yeelanna. 



VAR. Specimens from Ankertell, Western Australia differ somewhat from 

 the Yeelanna specimens. The clothing is lighter brown, with the pale squames a 

 pure white, in some places with a pink tinge; the elj-tral tubercles are rather 

 smaller, and more numerous in the tirst row (10 — 11); the gi-anules, particularly 

 on the first and second interstices, are also smaller and less prominent.

c?. Black: moderately densely clothed with brown, depressed subpubescence; 

 with wtiite subsquamose clothing forming a median vitta from head to apex of 

 elytra, irregularly disposed macules on elytra, and an interrupted vitta along 

 lateral margin of disc of elytra; .sides of prothorax and a broad vitta along the 

 inferior margin of sides of el^'tra also clothed with white; under surface and 

 legs with longer white subpubescence more sparsely disposed. 



Head rather shallowly excavate in front: intereristal ridge low; supraorl)ital 

 crests composed of two slender, curved rami, distinct almost to base, the anterior 

 curved foi-wards and upwards, the posterior upwards with a slight inclination 

 backwards. Rostrum shallowly concave, almost flat above, with a somewliat indis- 

 tinct median carina; lateral margins with a conical tubercle in middle; internal 

 ridges Iiardly raised, widely separated at base; basal foveae distinct, closed. An- 

 tennae long and slender, first joint of funicle about equal to seeond, club with a 

 moderately long peduncle. Prothorax with submedian tubercles in single series, 

 erect, spiniform, slightly decreasing in size posteriorly; lateral tubercles spini- 

 I'orm, the middle one long, curved slightly back at apex, conjoined anteriorly 

 with a smaller spine, the posterior spine well developed and acut<?, but distinctly
