yellow, and with a black mark in the centre of the yellow portion. The sides of the 

 middle lobe of the mesonotum are bordered with yellow, somewhat interrupted towards 

 the middle ; the sides of the scutellum are broadly bordered with yellow, and towards 

 the apical third the yellow projects in a triangle to the middle on both sides ; the apex 

 is depressed and rounded, not projecting much over the metanotum, which is yellow at 

 the sides close to the petiole ; the petiole is narrow and about three fourths of the 

 length of the abdomen, which is not longer than the posterior coxa?. The sides and 

 ventral surface of the abdomen are reddish yellow. On the top at the base is a large 

 triangular mark, of which the sharp end is in front; behind this is a large broad 

 transverse mark, interrupted at the top ; behind this, again, are three shorter yellow 

 marks, which do not reach the top, and close to the apex and more to the top is a more 

 rounded mark. All these have the yellow surrounded with brown, which passes 

 imperceptibly into the yellow. The four anterior legs are yellow, the femora having 

 a testaceous tinge. Internally the apical two thirds of the posterior femora are 

 yellow, bordered with brown ; on the outside the apical two thirds are yellow, except 

 at the top, and the apex is more or less brownish ; on the top above and in front of 

 this yellow portion is a yellow mark, which is longer than broad. The posterior tibiae 

 are yellow, variegated with testaceous and posteriorly with black.

The body is covered with a longish pale pubescence. Antennae thick, the joints 

 closely pressed together; the apex sharply conical and brownish on the underside. 

 Scape yellow on the underside ; the face below the antennae, the lower orbits of the 

 eyes within and without are yellow, but the part opposite the ocelli is black ; the front 

 between the ocelli and the base of the antennae black. The mesonotum is punctured ; 

 the mark on the pronotum reaches to near the middle above, is large and somewhat 

 triangular, but longer than broad. The longitudinal marks on the mesonotum reach 

 a little beyond the middle, and converge at the apex. The scutellum is almost entirely
