340 NOTES ON AUSTRALIAN COLEOPTERA, 



N.B. — An example taken near Adelaide is somewhat larger 

 (long. 1 1 line), has the scales on its elytra disposed without any 

 distinct pattern (the paler scales however being somewhat con- 

 densed near the apex), and has the apical joints of its antennal 

 funicle less transverse with the club more elongate, but does not 

 differ otherwise. I hardly know whether to regard these charac- 

 ters as sexual or as marking a distinct species. 



Cydm^a diversa, sp.nov. 



Breviter elliptica ; nigra ; squamis pallidis (supra sparsim 

 subtus sat confertim) vestita; rostro quam pr^ecedentis paullo 

 tenuiori, prothorace manifeste longiori ; antennaruiu funiculi 

 articulo 1° quam 2"* 3'-' que conjuncti baud breviori, 2° 3° 

 duplo longiori, ultimis vix transversis ; prothorace leviter 

 transverso, antice angustato, lateribus leviter arcuatis paullo 

 pone marginem anticum leviter constrictis ; elytris striato- 

 punctulatis, humeris vix callosis ; mesosterno quam C. luc- 

 tuosce (Pasc.) sat latiori ; coxis anticis baud contiguis. 



[Long. 1|, lat. I line. 

 As in C. ohscura the whitish scales present, from some points 

 of view, a nitid brown and silky appearance ; they do not form a 

 well-defined pattern ; they are most conspicuous about the sides 

 of the basal portion of the prothorax and are condensed in 

 numerous small inconspicuous spots all over the elytra. The 

 front coxse not contiguous will separate this species from all others 

 previously described in the genus.

Cydm^a invalida, sp.nov. 



Elliptica ; minus lata ; nigra, antennis tibiisque rufescenti- 

 bus ; squamis pallidis (supra vix conspicue subtus sat confer- 

 tim) vestita ; rostro sat gracili, prothorace vix longiori ; 

 antennarum funiculi articulo V quam 2"^ 3"^que conjuncti 

 vix longiori, 2° 3° vix longiori, ultimis vix transversis ; 

 prothorace vix transverso, antice angustato, lateribus leviter 

 arcuatis paullo pone marginem anticum vix constrictis; elytris
