Trans. Eiit. Soc. N. S. Wales, ii. 1873, p.324. 



After examination of the types of Ph. costalis^ Macl., and PJi, 

 lateralis., Macl., in comparison with a specimen in my collection 

 from Kalgoorlie, I cannot consider Ph. lateralis more than a 

 small form of Ph. costalia. I place Ph. crassus, Blackb., under 

 Ph. costalis for two reasons, firstly, because a careful study of the 

 description discloses nothing to differentiate it from m}^ specimen 

 of Ph. costalis from Kalgoorlie; secondly, because the identitica- 

 tion of Ph. lateralis as synonymous with Ph. costalis will extend 

 the range of Ph. costalis sufficiently to take in the locality of 

 Ph. crassus. 



Hab.—W.A. : Nickol Bay (Jicle Macleay), Yilgarn (Jide 

 French), Kalgoorlie (G. W. Froggatt) — S.A. : Wallaroo (type 

 Ph. lateralis, in Australian Museum), Ouldea {fide Blackburn). 



Philoscaphus bicostatus, n.sp. 



Black, prothorax very wide, transversely rugulose-striate, 

 lobate; elytra narrower than prothorax, bicostate; anterior tibiae 

 tridentate, intermediate tibise strongly unidentate externally at 

 apex. 



Head transverse-quadrate (6-3 mm. across eyes), similar to that 

 of Ph. mastersi, Macl. Prothorax transverse (5 x 8*3 mm.); disc 

 transversely rugulose ; anterior margin truncate behind head; 

 anterior angles obtuse, shortly and decidedly advanced; sides 

 subparallel; posterior angles widel3M'ounded; basal curve strongly 

 sinuate on each side; basal lobe rounded; marginal channel wide, 

 shallow on sides; border lightly reflexed on sides, strongly so at 

 posterior angles. El3nra narrower than prothorax, truncate- 

 oval (11 X 7'8 ram.); surface rough, a narrow sharply raised con- 



* Under Ph. tuhercidatiis, Macl., I place Ph. tepperi, Blackb.
