92 REVISION OF SYMPETES AND IlEL^US, ETC., 



I have examined many s[)ecimens of //. moniliferus in the 

 Macleay Museum, which are cotypes of those sent to Pascoe by 

 Mr. Masters from South Australia. I have received specimens 

 from Mr. Goudie from Sea Lake, N. W. Victoria. 



H. ellipticus Lea, is easily diflferentiated from the former two, 

 by its elongate-ovate form, the sides being parallel behind tlie 

 shoulders. The prosternal keel is strongly raised throughout, is 

 notched, bifid, and wedge-shaped at apex, and strongly produced 

 behind coxje; the elytral costse are crenated only on the outside 

 (on both sides in the former two species), and there is a raised 

 border round the eyes with a sulcus intervening between it and 

 the eyes. Mr. Lea has kindly lent me his type for examination. 

 My specimens are from Condon and Mt. Margaret, "VV.A. 



H. castor Pasc. — This species, and its ally H. Georgei Cart., aie 

 much flatter than the rest, with the prosternal keel obsolete. 

 The under side of the prothoracic flange of H. castor is thickly 

 pitted with large punctures. 



H. squamosus Pasc. — Specimens compared with cotypes in the 

 Macleay Museum have the front angles rounded and overlapping, 

 with the ii\jtia\ costse terminated on the apical declivity. The 

 four apical joints of antennse are distinctly broader than the rest. 

 My specimens are from Cunuamulla, Q.; Milduia, Vic; and 

 Tarcoola, S.A. 



H. Derbyensis Macl., compared with what, I presume, is the 

 type, though unmarked as such in the Macleay Museum. The 

 front angles are acute and scarcely overlapping, the pronotal 

 carina smaller and more uniformly elevated. The last three 

 joints of antennse are not broader than the rest, while the elytral 

 costee are continued almost to the apex. The suture is slightly 

 carinate at apex, though Macleay says it is not. My specimens 

 are from Condon, N.W. Australia, taken by Mr. Giles. 



In both the last two species the prosternum is nearly flat. 



H. Mastersi Pasc. — There is a specimen labelled Salt R.(W. A.) 

 in the Macleay Museum which, Mr. Masters assures me, is a 

 coty|)e of the specimen sent to Pascoe. If this be so, Pascoe's 

 description is in error in stating that it is "furnished above with
