[Jah. — New South Wales; Narrabri (Musson), Warialda District 

 (Sloane). 



I received both $ and $ from Mr. Musson, who took them at 

 Narrabri, and formerly I had a ^ taken by myself in the Waiialda 

 district. I believe this to be the insect to which de Castelnau 

 refers when he says, under the name P. striato-punctatus, he 

 has a specimen from the Darling River* ; however, apart from 

 the inappropriateness of the name striato-jninctatus, I hardly think 

 this species will be found to extend to Victoria. I have already 

 expressed the belief that P. striato-punctatus, Casteln., = P. 

 7iigrico7'7iis, Casteln. f This species is allied to P. comes, SI., from 

 which it differs in its narrower form, in the prothorax being 

 proportionately broader in comparison with the elytra, in its 

 larger head, blacker colour, and in the marginal border of the 

 elytra not being entire on the base, &c. 



Promecoderus concolor, Germ. 



When reviewing the genus Promecoderus two years ago I 

 followed de Castelnau, who had been followed with doubt by M. 

 Putzeys in his Revision des Broscides de I'Australie, and main- 

 tained P. Jioioitti, Casteln., as a species distinct from P. coricolor, 

 Germ. Since then I have obtained a larger series of specimens 

 from different localities, which convinces me that they must be 

 regarded as one species, and that P. anthracinus, Macl., and P. 

 politus, SI., must also be placed as synonyms of P. concolor. I 

 further sink P. lucidicollis, Casteln., to the rank of a variety, and 

 regard P. ohlongus, Casteln., as a synonym of P. lucidicollis. M. 

 Putzeys gives the dimensions of P. oblongus, Casteln., as 12x4-^ 

 mm. 



The synonymy will, therefore, be: — P. concolor, Germ., = P. 

 suturalis, Casteln.; P. lucidus, Putz., (these agree with the typical 

 form of P. concolor); P. howitti, Casteln.; P. anthracinus, Macl.; 

 P. politus, SI. (the last three are identical, but do not seem to me
