 macules less iijarked- Rostrum with a small tubercle on external margins, head 

 and prothorax otherwise as in specimens from Ankertell; antennae with moder- 

 ately long peduncle to club. Elytra with evident granules between the rows of 

 tubercles; the tubercles smaller than in typical specimens, 8, 9, and 4 in number.

ACANTHOLOPHU.S CLPREOMICANS, u.sp. 



d. Large, robust, closely allied to A. humeralis Miicl. Black; densely cloth- 

 ed with siiort subsquamose pulieseence of a coppery colour with metallic lustre, 

 the clothing sparser on prothorax; sides maculate with white, on prothorax be- 

 neath expanded margin of disc, on elytra irregularly disposed. 



Head concave in front, intereristal ridge definite, moderately low in centre; 

 supraorbital crests stouter than in A. hitmeralh, especially the anterior ramus 

 which projects strongly forwards at base. Rostrum somewhat shorter than in A. 

 humeralis, external margins raised in a strong, conical, pointed tubercle; internal 

 ridges low, basal foveae distinct. Antennae as in A. humeralis. Prothorax 

 rather strongly produced in front ; median area rather wide, parallel sided, me- 

 dian line lightly impressed ; submedian tubercles in single series, shorter than in 

 A. humeralis, subequal and set in straight line, except the basal pair which are 

 smaller and closer together, apical tubercles somewhat cristaform; lateral mar- 

 gins with a long acute spine in front of middle, with a smaller one conjoined 

 anteriorly, and two small dentiform tubercles ])osteriorly in the position of the 

 posterior lateral tubercle- Elytra almost paraUel-sided, less convex than in A. 

 humeralis; punctures rather obscure, granules small but fairly regular; with thi"ee 

 rows of tubercles, first with 9 — 10. mostly small or granuliforni, the last 2 larger 

 acute spines; second with 7 — 8, all acute, but the last 4 larger, slender acute 

 spines, ending posteriorly to the tubercles of first row; humeral tubercle single, 

 large and acute; third row with 4, all acute but decreasing in size posteriorly. 

 Venter flattened, with large longitudinally confluent p\inctures, the intervals 

 raised and strigose. Intermediate tibiae with subapical emargination, not quite 

 as deep as in A. humeralis, posterior tibiae similar to A. hunkeralis. 



9. Larger, with broader elytra; clothing similar but side sjiots bluish; 

 elytral tubercles smaller, 10, 8 and 4 in number; venter convex, with sculpture 

 subobsolete. Dimensions: d. 17.. 5 x 7 mm.; ?. 19 x 8.5 nun. 



//n6.— Western Australia: Mt. Barker, Parkerville. DescrilK'd Iroin 4 speci- 

 mens, two males in the collection of the Australian Muscuin, ami two females 

 received fi'oni Mr. J. Clark, from Parkerville. 



Closely allied to .1. humeralis Mad., the present species, apart tVom clothing, 

 differs in the stouter suiiraorbital crests, in the shorter rostrum with larger mar- 

 ginal tubercles, in the wider, parallel-sided median area of the piothorax and in 

 the shorter elytral tubercles. The contra,st in the clothing of this sjiecies as coni- 

 pared with that of A- humeralis is most marked. 



Holotype male in Australian Museum, allotype female in Coll. Ferguson. 

 paratype female in Coll. Clark. 



ACANTHOLOPIIUS OCELLIOER, n.Sp. 



d". Size moderately large, flattened above. Densely clothed with dark 

 brown subsetose clothing; prothorax with lateral areas clothed with cinnamon-
