joints somewhat broader than those of the flagellum, and very 
small. The first twelve flagellar joints each bear a finger-like 
pectination, nearly as long as the whole flagellum, the first 
nine joints closely sessile and very small, gradually lengthen- 
ing from tenth to twelfth, the latter as long as the two preceding 
joints. The pectinations of the first five joints are decumbent, 
the rest gradually arise to nearly porrect in the last three, 
though the apices of these bend slightly downwards. Apical 
joint simple, as long as preceding three together. The pecti- 
nations closely set with fine hairs, and bearing a terminal 
black bristle.

bristles, pleuree concolorous, metapleuron with black bristles.

width of scutellum.

apically. Tergal plates of hypopygium twice the length of 
the sternal. First segment wholly yellow, second to sixth 
with basal half black and apical yellow, seventh and eighth 
and genitalia wholly black. Venter banded similarly. 
Legs.—Yellow. Tibiz and tarsi closely set with minute 
black sete. Spines of mid-tibiz much longer than those of
