submarginal bears a long bristle at one-third from the base ; a lit"^le nearer the base, 

 but below, is a clear non-setigerous pustule. Submarginal cell narrow, with about 

 10 bristles below ; 10 to 12 stout bristles fringing the marginal appear over the costa. 

 Radius wit h 4 bristles on stalk, one at the heel and one below the clear cells. There 

 is a bare area below the origin of Ihe marginal vein, and the basal triangle before the 

 < row of hairs is also bare. Elsewhere the pubescence is regular and dense.

Xe^rs.— Forelegs : coxae two-thirds as long as 1 he femora, which are only moderately 

 swollen and have a ventral row of bristles (8-10) ; on the posterior aspect the femora 

 are covered with evenly set bristles, but anteriorly the surface is bare ventrally to near 

 the apex ; apex of tibia with a row of 5 spines, and 6 along the anterior edge of first 

 tarsal joint. Mid legs : femur bare both anteriorly and posteriorly on an area 

 defined by a line from the upper basal to the lower apical angle, except for one or two 

 posterior subventral bristles, one before and one after one-half respectively, and two 

 rather strong subapical ventral bristles ; numerous bristles along the dorsal edge on 

 both sides broadening towards the apex ; apical spine as long as the first tarsal joint. 

 Hind legs : femur sparsely clothed ; two bristles about the middle of the ventral 

 edge, and 10 to 11 in a subventral row anteriorly ; apical comb on tibia of 10 or 11 

 spines ; tibial spur shorter than the first tarsal joint. The proportions of the tarsal 

 joints are :—
