viridlaureiis, but the shape of the prothorax is variable in P. 

 alternans. The specimen in my collection with the most elongate 

 prothorax is from Ourimbah, south of Newcastle; in this char- 

 acteristic it surpasses specimens sent to me from Brisbane by Mr. 

 R. Illidge under the name of P. viridiaureus, MacL, and identified 

 by me as that species by comparison with the type in the Macleay 

 Museum.

When dealing with this species Chaudoir had in his possession 

 Crory's collection, including the type of P. cunninghami, Casteln^, 

 which he placed as a synonym of P. morbillosus. I translate his 

 remarks as follows : — The type of morbillosus which I possess is 

 closely allied to, and perhaps only a variety [of P. alter7ians\', 

 however, I must note that it is smaller, the prothorax more 

 rounded on the sides, which makes it appear more narrowed 

 behind, the elytra are shorter, more convex, and m}'- specimens 

 are of a bronzy-copper colour which I have never seen in P. 

 alternans or P. elongatus. 



Chaudoir's remarks apply to specimens in my collection given 

 to me by Mr. R. Illidge as from Dalveen, Queensland (near the 

 New South Wales border), and also to another specimen given 

 to me by Mr. Froggatt as from the Bellinger River, N.S.W.

I have seen the type (the only specimen as yet recorded) of N.
