 the median basal lobe ; scutellum luteous ; on each elytron, a broad, oblique, reddish- 

 luteous fascia near the base, which does not extend to either the side or the suture, 

 its upper margin (at the inner side) with a deep semi-circular notch, the lower 

 margin with two similar but (especially the inner one) smaller notches ; the apex — 

 except near the suture — broadly pale luteous, the rcflexed margins entirely reddisli- 

 luteous ; minutely seriate-punctate ; under-side eastaneous ; epipleural fold, legs,

 black fasciae : the first sub-basal, incomplete, the outer half being represented by a
