 description which I can confirm is the denuded appearance, 

 which is an unmistakeable reality. I think Pascoe must have 

 made a mistake in the locality and imagined the rest."

In commenting (23) on the synonymy of fuliginosus, I was 

 somewhat dubious as to luridus really being the same species, 

 as Pascoe stated that it was a Poropterus; I have seen the 

 type of fuliginosus, which is certainly the same as immansuetus 

 and plinthoides, and Mr. Arrow has recently compared the 

 types of luridus and plinthoides , and considers them identical.

There are before me 28 specimens, all of which I believe 

 to be westermanni, but they present considerable differences 

 in size, colour, and clothing. The difference in appearance 

 of the clothing is often due to partial abrasion (24) and to the 

 colour of the derm upon which it is resting, but on some 

 specimens it is beautifully regular, and on others it appears 

 to be rougher, this, however, probably being due to some 

 of them having been preserved in alcohol. The colour of the 

 derm varies from entirely pale reddish-brown to entirely deep 

 black, many specimens have the elytra and appendages con- 

 spicuously paler than the head and prothorax, some have 

 the elytra only paler, and some have only parts of the head 

 and of the antennae darker than the other parts. On the 

 male the prothorax is rather shorter than on the female, and 

 with the front angles more conspicuously rounded off, its 

 elytra also are proportionately wider than on the female, and 

 the antennae are slightly longer. The specimens commented 

 upon or described by Blackburn ( 25 > were all taken by Mr. 

 Meyrick at Geraldton, and of these there are in the Museum 

 two doubtfully identified as westermanni, two marked as

(24) On partially abraded specimens there are seen to be seriate 

 rows of large punctures on the elytra, but these are normally 

 almost or quite concealed.
