than prothurax; little rounded on sides. Disc with three rows of 

 spinoee tubercles, the intermediate interstices rather coarsely" 

 granulate, suture granulate, the granules not extending down 

 declivity; first row with eight or nine tubercles, the basal ones 

 small, rounded, becoming progressively larger, the last three or four 

 spinose, the last one the largest; second row not quite reaching to 

 base, running obliquely backwards and outwards, about seven to 

 eight in number, the tubercles small at base, becoming progressively 

 larger and more spinose, the last four or five strong, outwardly 

 directed, spines, reaching slightly beyond first row; third row 

 extending from shoulder back, with a slight inclination outwards, 

 consisting of five large, outwardly directed, spines, the basal two 

 more or less conjoined, larger than the others, the rest sub- 

 equal. Sides with two upper interstices granulate. Beneath rather 

 closely, somewhat rugosely, punctate, the basal segments trans- 

 versely strigose. Legs simple; tarsi spongiose beneath except along 

 median groove. 



$ Resembles c? , but is much larger ; elytra wider than prothorax ; 

 spines on elytra somewhat smaller, the two humeral spines almost 

 completely conjoined to form an oblique humeral crest ; convex 

 beneath, basal segments more lightly strigose, other segments hardly 

 rugose.

Hah. — Victoria, Portland (J. E. Dixon). Type in Coll. Ferguson. 



Described from 2 (? c? and 11 ? $. In the type 3' the humeral 

 tubercles are separate, except at base, in the other <? and in all the 

 females, these are almost completely conjoined. 



In appearance a very ordinary Acantholophus the present species 

 may be separated from most by the simple supraocular crests. Of 

 the described species with simple crests, it differs from all except 

 A. gladiator and A. aureolus, in having the intermediate tibiae 

 simple and not notched at apex. From the other two, it is bo 

 utterly different that no comparison is necessary. Apart from the 

 simple crests, the present species strongly resembles many of the 

 Adelaidae-group. 



Acantholophus brevicornis, sub. sp. nov. 



(? Moderately large, elongate, suboblongate ; very close to Ac. 

 dumosus. Black; sparsely clothed with brownish squames above, 

 sides maculate with greyish.
