624 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



O. PATRUELis, Pasc. — Certainly a variety of cijlindrirostris. 



O. TENELLUS, Pasc. — A distinct and very common variety in 

 Western Australia. 



O. LATERALIS, Pasc; O. VAGUS, OlliflF. — Both these are varieties 

 from Lord Howe Island. I have specimens of both. 



O. EUCHROMUS, Pairm. — Perhaps entitled to varietal rank ; 

 certainly not to specific. 



O. s;iMULANS, Bohem. — Doubtful if even entitled to varietal 

 rank. 



The following are well marked varieties, and appear to be 

 undescribed : 



O. CYLiNDRiROSTRis, var. POMicOLA, var.nov. 



Apical fascicles of prothorax well-developed, ferruginous; base 

 with a large ferruginous patch divided into two by a pale median 

 line. Scales of elytra divided into two distinct patches of almost 

 equal extent, the basal mixed grey and ferruginous, the apical 

 entirely ferruginous. Elytra with a small basal tubercle on 2nd 

 interstice and a rather large median one (on which the two patches 

 of scales are divided), which is slightly larger than the preapical 

 callus. Length 12-15 mm. 



Uab. — South-Western Australia. 



Abundant in Spring, and very destructive to the bark and 

 young shoots of various fruit trees, especially the peach and 

 apricot. The variety tenellus may frequently be seen on grape 

 vines.

Head with dense white scales, terminated at base of rostrum 

 in 9) continued almost to apex but gradually narrowed in ^. 

 Apical fascicles of prothorax small, but prominent and acute. 

 Elytra with more or less uniform scales; 2nd interstice with basal 

 tubercle almost obsolete, the median one with dark scales and 

 smaller than preapical callus, the latter prominent and acute.
