XXXIII. — A new Species o/ Rhysodina {Cofeopfera 

 Ileteromera). By K. G. Blair, B.Sc., F.E.S. 



(Puljlislied by permissiou of tlie Trustees of tlie British Museum.) 



[Plate VI.] 



Amongst the Heteromera collected by Mr. G. A. K. Marshall 

 in South Africa and recently presented by him to the British 

 Museum are contained three species of particular interest 

 belonging to the highly anomalous group Khysopaussida? 

 (Wasmann). One of these is undescribed, and having regard 

 to the scarcity of the members of this group, both in species 

 and in individuals, and to our very meagre knowledge of 

 them, it appears disirable to describe it. 



I place it provisionally in the genus Rhysodina of Chevrolat, 

 since, though it differs considerably from the typical R. mni- 

 zechi, even more so perhaps than does Apistocerus icasmanni, 

 Fairm., for which the author created a new genus, it seems 

 inadvisable, in the present state of our knowledge, to multiply 

 too hastily the number of genera.
