 transverse keel, this part becoming gradually narrowed, 

 from its outer edge at the apex a line of equal width runs 

 along the edge of the )>leui8e to near the spiracles and below 

 alons: the coxa?, a broad curved mark on the lower edoe of 

 the mesopleurge, the base bemg narrower and continued 

 higher up than the apical, and lines of equal width on the 

 ajjices of the abdominal segments, pale yellow. Four front 

 legs pale fulvous, paler at the base; the fulvous tint on the

 closely, distinctly punctured, finely stiiated on the edges of 

 the lobes ; the scutel'ium smooth, its basal depression deep 

 with four stout keels ; the mesopleura? stoutly striated, 

 except in the middle at the apex. On the base of the 

 metanotum is a band of stout strife, closely pressed, but 

 cleaily sejjarated ; the space between them and the keel is, 

 in the middle, coarsely, closely shagreened, almost punctured ; 

 the sides have the junctures clearly separated. Metapleurie
