DESCRIPTIONS OF NEW SPECIES OF AUSTRALIAN 

 COLEOPTERA. Part xii. 



By Arthur M. Lea, F.E.S. 



Family CURCULIONID^. 

 Rhinoscapha* darnleyensis, n.sp. 



^. Black. Clothed with scales mostly more or less bluish; 

 the elytra with conspicuous markings. 



Head with minute punctures; interocular fovea rather deep 

 and marking the end of the median groove of rostrum Rostrum 

 about as long as prothorax; with rather large, irregularly dis- 

 tributed punctures. Antenna? rather thin ; second joint of 

 funicle slightly longer than first, the others all distinctly longer 

 than wide. Prothorax apparently slightly longer than wide, but 

 (by measurement) really slightly transverse; with rather small 

 scattered punctures, the sides with numerous small irregular 

 elevations, a small medio-apical impression. Elytra not much 

 wider than prothorax at base, sides slightly dilated to beyond 

 the middle, with regular rows of large, sharply defined punctures, 

 becoming smaller posteriorly. Xe^s long and thin. Length(^9), 

 15-19 mm. 



5. Differs in being larger, prothorax somewhat shorter, elytra 

 conspicuously wider, abdomen more convex, and legs shorter. 



Hah. — Darnley Island (H. Elgner). 



The discovery of a species on Darnley Island brings this fine 

 genus into the Australian region, although it has yet to be 

 recorded from the mainland;! it is structurally close to R. 

 biundulata, R. tricolor, R. egregria, and R. consueta, but readily 

 distinguished by the blue scales; these are rather sparse on the

 1 1 have had for many years a specimen (probably of an undescribed 

 species) supposed to be from Queensland, but have been unable to get the 

 locality confirmed.
