Tliis is a more robust species than agluia, Handl., or 

 t/ia/ia, Ilandl. The j)eunltimatc joint of the antennaj is 

 slightly excavated beneath, but not as strongly as in aglaia. 

 The yellow apical bands on the second and third dorsal 

 segments are extremely narrow, almost obsolete. The thora.x 

 is more sparsely punctured than in aglaia.

Long. 11 mm. 



J. Antennae simple, the second joint of the flagellum 

 longer than the scape, equal to the third joint. Clypeus 

 very slightly convex, the apical margin straight ; a distinct 

 groove running from the anterior ocellus to the antennae. 

 Eyes converging towards the clypeus, but not quite as 

 stiongly as in natalensis, Sra. The whole insect shining, 

 the punctures microscopic ; head and abdomen clothed with 

 a tine silky pubescence; a transverse row of large putictures 

 at the base of the scutellum ; four indistinct longitudinal 

 grooves from the anterior margin of the mesonotum ; the 

 marginal and median grooves of the smooth basal area of 

 the median segment striated. First abdominal segment 

 slender, distinctly constricted at the apex. Second abscissa 

 of the radius a little longer than the first ; second recurrent 

 ncrvure received a little farther from the apex of the second
