I possess a specimen from Rockhampton. 



Utana^ gen. nov. 



Head moderately long, rounded anteriorly, central lobe 

 very slightly produced ; eyes moderately large and globose. 

 Antenna with the second joint a little shorter than the third, 

 fourth longest, fifth mutilated. Pronotum deflected in front 

 from between the posterior angles, wliicii are strongly and 

 acutely produced, the lateral margins concavely sinuate, the 

 anterior angles distinctly dentate. Scutellum subtriangular, 

 deflected towards apical area, apex narrowed and rounded. 

 Apical angles of sixth abdominal segment acute, but not 

 prominently produced. Rostrum reaching the third abdo- 

 minal segment, its third joint longest. Sternal keel not 

 extending beyond the anterior coxas, its posterior extremity 

 notched and receiving the apex of the short ventral spine. 



This genus differs from Cuspicona, to which it is allied, by 

 the length of the third joint of the rostrum, and from Pugione 

 by the much shorter rostrum.

Bergroth's description is much the more exact in all parts, 

 save the colour of the abdomen above, whicii is not alto- 

 gether " nigro-violaceum," but only the apical area from 

 about apex of scutellum, and which Walker describes as 

 " abdomen with a very large purple apical patch." I have a 

 series from Ceylon and also a specimen collected on the 

 Nilgiri Hills by Sir G. F. Hampson. 



Long. 15-17 millim. ; exp. pronot. angl. ll-li millim.
