586 NOTES ON AUSTRALIAN COLEOPTERA, 



DiCOMADA. 



In characterising this genus Mr. Pascoe does not describe the 

 claws nor the relative length of the ventral segments. In the 

 specimens before me which appear to belong to it the claws are 

 divaricate, the 2nd ventral segment is slightly longer than the 

 next two together, and the 1st ventral suture is arched ; the basal 

 2 ventral segments are together much longer than the other 3 

 together, the 2nd scarcely longer than the apical one (measure- 

 ments down the middle line). 



DiCOMADA LITIGIOSA, PaSC. 



I have specimens from Western Australia which appear to be 

 this species ; they fit the description satisfactorily in all respects 

 except the sculpture of the rostrum. Mr, Pascoe says that the 

 rostrum is " basi subtiliter lineatim punctulatum." I think "basi 

 subtiliter punctulato-striatuin " would apply better to the rostrum 

 of the example before me, but the discrepancy is hardly sufficient 

 to suggest specific distinction,— it may be a mere matter of words. 

 The basal half of the rostrum is finely striated longitudinally and 

 each stria contains a row of punctures, — the interstices appearing 

 as excessively tine carinse ; in some examples the striae are very 

 distinct and punctured throughout while in others (taken in 

 company with them) the strise are scarcely marked and punctured 

 only in their basal half. 



DiCOMADA RUFA, Sp.nOV. 



Rufa ; rostro (parte apicali excepta), capite, prothoraceque plus 

 minus picescentibus vel subnigris; argenteo-squamosa; squamis 

 (his hie illic subcupreo-micaatibus) subtus dense sequaliter, 

 supra minus confertim in elytris obscure subbifasciatim, 

 dispositis ; antennarum funiculi articulo 1° 2° paullo longiori ; 

 rostro prothoi'ace sesquilongiori basi subtiliter 5-carinato ; 

 elytris punctulato-striatis, puncturis magnis, interstitiis sat 

 planis uniseriatim punctulatis. [Long. 1| (vix), lat. ^o li^ie.
