524 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



Prothoracic strife deep and straight, shorter than on elytra but 

 more thai> half the lengtli of prothorax itself. Elytra rather 

 strongly and densely punctate except at side. Length 2| mm. 



^. DiflFers in being slightly larger and paler, head testaceous 

 with the base infuscate. 



//«6.— Forest Reefs, N.S.W. 



The stronger punctures of the elytra do not appear to extend 

 outside of an imaginary line continued from the basal strinp. I 

 have seen many thousands of specimens, but only at Forest Reefs. 



BiDESSUS LUiUDUS, Macl. — In the index to Dr. Sharp's Mono- 

 graph and in Mr. Masters' Catalogue this species is placed as a 

 synonym of bistrigatus. Dr. Sharp places bistrigatus (of which 

 he evidently knew the types) in the section in which the species 

 are without subsutural striae. Sir Wm. Macleay's description of 

 iuriihts is very brief and rather misleading, as he states that 

 " these (the elytra) are entirely without the subsutural stria." I 

 have four co types of luridus, and in them the sutural striie, 

 though apparently absent when the elytra are viewed from above, 

 are distinct when viewed from behind, and if they are brushed 

 with water the strias can be seen from any direction. The species 

 is widely distributed, as besides the specimens from Gayndah I 

 have others from New South Wales and Western Australia. I 

 am not, however, prepared to say that luridus is not a synonym 

 of bistrigatus as Dr. Sharp says of section B : — " Wing-cases 

 destitute of a distinct sutural stria." 



BiDESSUS MUNDUS. Sharp. — I have three specimens (from 

 Sydney and Windsor) which agree exactly with the description 

 of. this species except that they are slightly smaller (2| mm.). 

 Dr. Sharp doubtfully records the species from Western Australia
