description, the one useful fact therein being its locality, Kangaroo 

 Island. De Breme redescribed it, giving a figure, as from Swan 

 River. lb seemed improbable to me that this distribution, and, 

 therefore, identification was correct. I was unable to find Bois- 

 duval's tj^pe in the Paris or Brussels Museums, but Mr. Gahan 

 has kindly sent me a specimen labelled H. Perronii Boisd,, from 

 the British Museum for examination, with the locality-label of 

 Kangaroo Island(A. H. Davis). This specimen is identical with 

 specimens in the Macleay Museum, and Mr. Lea's collection, as 

 H.falcatus Pasc, and corresponds exactly with Pascoe's descrip- 

 tion. It is probable that Pascoe relied on de Breme's monograph, 

 already shown to be fallible in the case of Sympetes tricosielhis 

 White. Until Boisduval's type is shown to be identical with 

 de Breme's, it is preferable to assume that the two insects 

 described from Kangaroo Island are the same. It is thus pos- 

 sible that one of the new species described below may be the 

 insect figured and described by de Breme as II. Perronii Boisd. 



a. consularis Pasc. — I have two specimens, exactly correspond- 

 ing to the author's description, from Kellerberrin, W.A., taken 

 by Mr. Duboulay, junr., and one from Norseman, W.A., which 

 difiers only in the prothoracic processes not meeting. I consider 

 this last only a variety. In these Proceedings, 1889, p. 1269, 

 Mr. Blackburn has some doubt as to the distinction between this 

 species and II. moniliferus. Macleay also notes that it was 

 unknown to him. Tiie follov/ing comparison of prominent 

 characters will therefore be useful : — 



H. constdaris Pasc. //. moniliferus Pasc.

shoulders. shoulders.
