arising from a moderately broad base, the anterior angle projecting downwards 

 and forwards, the posterior backwards and upwards, the free margin between 

 almost unbroken except for a slight dentation in the middle; crests obliquely set, 

 as viewed from in front, the upper end strongly directed outwards. Rostrum 

 deeply excavate, sides strongly raised, almost rectangular in front, posteriorly 

 sinking almost abruptly to base; upper surface with median groove bounded at 

 base by slightly elevated, subparallel, internal ridges; basal foveae rather large, 

 apparently closed. Antennae rather short, funicular joints comparatively short, 

 the first and second subequal, club obovate, not pedunculate. Prothorax (3X4 

 mm.) with moderately well developed ocular lobes; anterior constriction well 

 marked, not extending across median ridges; median area rather narrow, moder- 

 ately deeply impressed, the median tubercles conjoined to form a ridge on either 

 side, each ridge consisting of a moderately elevated anterior portion, merging into 

 a somewhat confused group of three or four tubercles, more outwardly placed, 

 followed by a short ridge hardly projecting over basal constriction, and by a 

 small granule posterior to constriction; lateral tubercles composed of two closely 

 united tubercles anterior to middle, and a considerably smaller, triangular one 

 posterior to middle; sides rather coarsely punctate. Elytra (8 x 5 mm. ) elongate, 

 not greatly ampliate, base subtruncate, humeral angles marked by a very small 

 nodule, apex separately, bluntly acuminate, leaving a moderately deep emargina- 

 tion; seriate punctures small, but well defined, granules obscured by clothing; 

 with three rows of strong tubercles, first row consisting of six, small near base, 

 becoming larger posteriorly and more acute, the last set on declivity and smaller 

 than the penultimate; second row of four, strong, conical tubercles, more out- 

 wardly directed, the last on declivity anterior to last of first row; third row 

 with a strong tubercle immediately behind himieral nodule, followed by a single 

 large tubercle, more outwardly placed. Sides with rather conspicuous rows of 

 punctures, the interstices without evident granules. Under surface flattened 

 over metastemum and basal ventral segment, elsewhere gently transversely convex ; 

 moderately closely setigero-punctate, the setae black, depressed, the punctures 

 coai-ser and more closely set on apical segment. Legs simple, intermediate tibiae 

 not notched. 



?. Similar, more ovate; head and rostrum similar; prothorax with median 

 area somewhat less depressed, the bordering ridges tending to resolve into their 

 component granules; elj-tra (8.5 X 6.5 mm.) wider, slightly less produced apical- 

 ]y, emargination smaller; tubercles similar but basal tubercles of first row less 

 prominent. Ventral segments more evidently convex- Dimensions: c?. 12 X 5 

 mm.; 2. 12 X 6.5 mm. 



Hab.—N.S. Wales: Blackheath. 



Described from 4 specimens. The type male has the clothing well preserved, 

 the others are more or less abraded and of a uniform dingy black colour. A. 

 nanus comes nearest to A. squ-amosm Macl., but may be distinguished by the 

 stronger and more numerous elytral tubercles; the other differences between the 

 species are more fully discussed under ^4. sqimmosus. 



ACANTHOLOPHUS PARVULUS, n.Sp. 



d'. Very closely allied to A. sqiiamosus, but with intermediate tibiae notched 

 near apex. Head and rostrum similar to A. nanus, but intercristal ridge almost 

 obsolete, only traceable from behind, the internal rostral ridges also hardly trace- 

 able. Prothorax (3x4 mm) similar, but median row of tubercles smaller, the
