Genus Cleonaria. 



Cleonaria, Thorns., Syst. Ceramb., p. 119 (1864). 



Narrow and elongate in form. Head slightly depressed between 

 the antennae. Antennae shorter than the body in both sexes, 

 densely setose, the setae being longer and forming a fringe on the 

 posterior side ; first joint shorter than the third, asperate in front near 

 the apex. Prothorax sub-cylindrical, scarcely broader than long, 

 slightly rounded in the middle at the sides, feebly raised in the 

 middle of the disc, impressed with a straight anterior and a sinuate 

 posterior transverse groove. Elytra more than twice as long as 

 broad, a little wider than the prothorax, and slightly wider 

 posteriorly than at the base. Intercoxal process of prosternum 

 narrow in the middle, and not strongly raised. Mesosternal process 

 nearly horizontal, prolonged between the middle coxae for the greater 

 part of their length. Legs rather short, the hind femora scarcely 

 reaching beyond the second abdominal segment. Tarsal claws 

 appendiculate in both sexes. Last ventral segment of the female 

 long, and impressed with a median line ; that of the male shorter 

 and narrower and without impression. 



Type of the genus : Cleonaria hicolor, Thorns. 



1. Cleonaria hicolor. 

 Cleonaria hicolor, Thorns., Syst. Ceramb., p. 119 (1864). 



Head and prothorax testaceous yellow, with a faint ochreous 

 pubescence, and furnished also with erect tawny setae ; head with a 

 dark spot behind the lower lobe of each eye, and sometimes also, 

 with a dark spot on each of the antenniferous tubercles ; prothorax 

 with a dark blue band along the lower part of each side ; antennae 

 black ; elytra pale yellow or stramineous ; body underneath, with 

 the exception of the pro- and meso-sterna, dark metallic-blue ; legs 

 black, varying to piceous. Head and prothorax distinctly but not 

 very closely punctured. Elytra setose, thickly and strongly 

 punctured, except near the apex ; slightly flattened along each side 

 of the suture. Antennae reaching to the apical fourth of the elytra 

 in the male, to a little beyond the middle in the female ; first joint 

 very thickly jmnctured.
