270 REVISION OF THE AUSTRALIAN SPECIES OF ADELIUM. 



examined the types of both species, this doubt has been removed. 

 The combination of differences pointed out in the diagnosis* are 

 sufficient to distinguish these otherwise closely similar forms. 

 The type of A. victorice is apparently male, much mutilated, 

 having only five joints left of one antennae, the other having 

 disappeared, together with the anterior tarsi and one posterior 

 leg. I have six specimens which I consider identical with A. 

 victorice from Illawarra, N. S.W. (Bulli and Nowra); and eight 

 specimens which I consider identical with A. pustulosum from 

 Gisborne and Bullarook Forest, Vic, and Lambing Flat, N.S.W., 

 while specimens from Mittagong, Gunning, and Forest Reef are 

 intermediate forms, having the wider, more explanate and more 

 coarsely sculptured prothorax of A. pustulosum with the widely 

 obtuse hind angle of A. victorice. As these last appear to be all 

 female, in the absence of any description of the female, I conclude 

 that they are probably sexual variations of A. victorice. 



Champion in 1894 described two species, A. tasmanicum and 

 A. 7ioduIosum,j whose types I have seen, and whose excellent 

 diagnosis leaves little room for comment. 



Lea next added four, A. capitatum, A. heterodoxum, A. regulare, 

 and A. minutum,\ and through Mr. Lea's courtesy I have been 

 able to examine his types. 



A. capitatum Lea, is a very distinct form, which I have from 

 Wee Waa, N. S.W., and is apparently widely distributed in the 

 western district of this State. 



A. heterodoxum Lea, is also very distinct, though its chief dis- 

 tinction comes from a character omitted in the original descrip- 

 tion, in that it is clothed throughout, even to the legs, with 

 upright brown pile. While in general form and in the length of 

 the third antennal joint it is similar to A. tenebrioides Erichs., it 

 differs from that species in being strongly pilose, and in having its 

 elytral intervals uninterrupted. The third antennal joint is not,
