 outside of the transverse cubital, almost touching it; the 

 stigma is white at the base, fuscous on the lower side. 

 Legs fulvous; the hinder tarsi white, except the apical 

 two joints, which are black ; the base of the middle coxae, 

 the hinder except for a fulvous mark at the base above, 

 and the middle beneath, the hinder trochanters, base and 

 apex of femora narrowly, the extreme base of the tibiae 

 and their apex more broadly, black; the hinder femora 

 with a distinct bluish tint. The petiole is distinctly 

 longer than the second segment, yellowish; a broad, 

 bluish band, near the middle, closely and coarsely punc- 

 tured; the apex more or less reticulated, and, in the 

 middle, transversely striated, and with a central and two 

 lateral narrow keels leading into an impunctate spot at the 

 apex. The second segment broadly blue at the base, the 

 apex more narrowly black ; at the base, on either side, is 

 a deep, oblique depression ; at the base, in the middle, is 

 a somewhat A-shaped depression, deep at the base, 

 shallower, wider, and obliquely striated at the apex ; at 

 the apex, on either side, is a wider, shallower, oblique 

 depression, narrowed and deep at the base, becoming 

 wider and shallower towards the apex. Near the base of 

 the third is a wide, shallow, semicircular depression, with 

 a narrow, straight keel in the middle at the base, and with 

 its sides obscurely striated ; the other segments smooth, 

 whitish at the apices. The petiole beneath is black at the 

 base, and irregularly marked with semicircular striations; 

 its apex, and the second and third segments in the middle, 

 testaceous.
