 two-thirds covered with similar pubescence ; the 4th has a similar 

 band, but widely interrupted in the middle ; the last is thickly 

 fringed on the sides with long pale fulvous hair ; it is closely 

 rugose. The ventral keel on the basal segment becomes gradually

 black ; above it is smooth and shining ; the clypeus is strongly, but 

 not very closely, punctured. Thorax thickly covered with short 

 black pubescence ; the mesonotum is closely punctured, except the 

 space on either side of the centre; the scutellum is similarly

 segment is more closely punctured, and if anything more strongly, 

 the hair, too, on it is longer and thicker. It has the base of the

 line may be interrupted in the centre and is covered with rufous 

 hair.
