The late Rev. T. Blackburn recorded seminigra as a 

 synonym of parry i, and I agree with that opinion. 



Diaphonia luteola, Janson. 



Of this species Janson says : "Most nearly allied to 

 D. xanthopygq, but very different in colour and sculpture." 

 But many specimens of xanthopyga agree exactly with his 

 description of the colours (head, apex and base of thorax, apex 

 of scutellum, suture of elytra, bcdy beneath, and legs black, 

 centre of abdomen pitchy, thorax, elytra, and pygidium tes- 

 taceous). The size also (10J lines) fits many specimens of 

 xanthopyga, which occur in Western as well as South Aus- 

 tralia. 



But the described ■ sculpture, "punctures forming three 

 striae on each elytron, the first sutural, the others on the disc," 

 is certainly at variance with xanthopyga, which has rather 

 numerous irregular punctures, sometimes appearing in feeble 

 striae, but certainly in many more than three on each elytron. 



Diaphonia vicina, Janson. 



This species was described as being "nearly allied" to 

 luteola, the latter being "most nearly allied to xanthopyga." 

 The description and figure, in fact, represent an insect rather 

 close to xanthopyga, but differing in having smaller punctures 

 and part of the head pale. Reference to the figure (plate vii., 

 fig. 2) was not given at the time the species was described, 

 and it was also omitted from Masters' Catalogue. 



Kraatz apparently had not seen the figure, or at least he 

 does not mention it. Nevertheless, he made the species the 

 type of his genus Dysdiatheta, the diagnosis of which is simply 

 a Latin translation of parts of the original description ; with 

 a note that, "The typical species, on account of its yellow 

 colouring, is somewhat like Diaphonia, but it cannot remain 

 in same on account of the prothorax, which is like that of 

 Hemipharis at the base." 



I have not, to my knowledge, seen the species, but refer 

 it back to Diaphonia, as Janson 's idea as to the position of 

 a species, which he described and figured, seems preferable to 

 that of Kraatz, who apparently knew it by the description 

 only, not a single particular being added to those given by 

 Janson. 



Diaphonia mniszechii, Janson. 



PI. xiii., figs. 141 to 147, 168, 169. 



The male of this fine species (which occurs from the Mallee 

 district of Victoria to the coast of Western Australia as far 

 north as Geraldton) may be readily distinguished from all
