Metriorehynchus melaspis, Bourg. {Porrostoma), Ann. 

 Soc. Ent. Fr., 1889, p. 235. 



A specimen (from N.W. Australia) agrees exactly with 

 the description of this species except that it is much larger 

 (14 mm. as against a maximum of 9 mm. known to 

 Bourgeois). But a number of species vary to an even 

 greater extent than this ; so, till evidence to the contrary 

 is forthcoming, I shall regard this species as being probably 

 a large specimen of melaspis.

I have examined the type of marginicollis and it belongs 

 to the species described by Waterhouse as the lateralis^ 

 of Redtenbacher. Macleay does not mention the rostrum, 

 but in his type it is long (much as in rhipidi^is). The 

 species varies considerably in size.

Metriorrhynchus vittatus, Blackb., T. R. S., S.A., 1886, 

 p. 258. 



A female specimen received from Mr. Blackburn and 

 bearing a label in his writing " vittatus Blackh." is probably 

 the female mentioned by him when describing that species. 

 I can only regard it, however, as one of the numerous 

 varieties of rufiiKnnis. At the same time, I do not think 

 that vittatus can possibly belong to that species, as the 

 antennae of its male are described as strongly flabellate 



* In the original description, however, Mr. Blackburn says: — 

 " In the male before me the elytral costae are scarcely splashed with 

 orange colour, in the female very distinctly ; probably these colour 

 characters are variable." 



t I have not seen the original description of lateralis.
