metallic rust with rose and green tinges; anteriorly an ellipitical spot (pseudo- 

 scutum), very nearly representing in form and color the shield of the female, limited 

 by a white border; then a median spot, a sort of center from which radiate white 

 lines which border four anterior elongate brown spots arranged in an arc; three 

 posterior elongate spots, the median spot being the larger, the two lateral spots may 

 be somewhat semicircular. A marginal groove similar to that of the young female, 

 limiting a border which is larger caudad, alternately marked with white and brown, 

 and divided posteriorly into 11 distinct dorsal festoons; the white rust is occasion- 

 ally almost effaced in the posterior half. Punctations are present on entire surface 

 as in female. Ventral surface similar to that of the young female, except for the 

 characters resulting from the form of the coxa\ Stigmata somewhat comma-form, 

 a little more elongated. Capitulum differs from that of the female as follows: Length, 

 650 to 825 JJ-; base longer, square or slightly longer than broad or slightly broader 

 than long.^ Mandibles 1.1 to 1.4 mm. long, digit 130 to 150 //; internal apophysis 

 elongated transversely, with straight base, tooth large and bifide; external apophysis 

 bidentate, terminal tooth subventral and small, the other very large. Denticles of
