spenceri; (b) with a single spinule beneath on each side, K. 

 froggatti and ;V. ceneomicans. 



(2) M. Tschitscherine has also informed me that he places a 

 high value on the upper side of the tarsal joints being longitu- 

 dinally striolate, as in iV". eqiies, Casteln. I made no use of this 

 feature, but now record that, among the described species known 

 to me, it is onl}^ present in -A^, slrzehckianus, ^j>/i<7/i/?si (of Sloane's 

 Revision), y7-o(/^rt^^/, eques and sjyenceri; also atrnj^ennis^n.^^. 



(3) I have also heard from M. Tschitscherine that he has reason 

 to think, though not speaking positively in any case, that : — 



(a) N. crcesus, Casteln., and N'. plutiis, Casteln., are two distinct 

 species. 



(b) J\^. kingi, Chaud., = A^ excisipennis, SI. This would leave 

 the species I have identified as iV. kingi^ Chaud., without a name. 



(c) ^V. paralleloniojyha, Chaud., is probably synonymous with iV^. 

 auricollis, Casteln., while N. opulentus, Casteln., is quite a distinct 

 species. 



The further investigation of these points by M. Tschitscherine 

 will be awaited with interest.

 (not Oniaseus rujipalpis, Casteln.). 



The species I regarded as Omaseus rujipalpis was wrongly 

 identified, and requires a new name."^ 



* The Rev. Thos. Blackburn has given me a specimen (taken by him in 

 the Victorian mountains) which he has identified as Omaseus rvjipalpis, 

 Casteln. I concur with this identification, and would refer it to SimodontuSy 

 but it differs from the typical species of that genus and leads towards Proso- 

 pogmus; it seems allied to S. grandiceps, SI. It is characterised by head 

 large (3"25 mm. across eyes); prothorax wide (3'25x4'6 mm.), posterior 

 m.arginal puncture distant from basal angle; elytra widely rounded at apex 

 without lateral apical sinuosities, third interstice bearing more than three 

 punctures; metasternal episterna quadrate; intercoxal declivity of prosternum 

 rounded, but broad in middle. Length 14 'S, breadth 5 '75 mm.
