d'-. Posterior ti))i;e red or orange. 

 e\ Lati'ial loI)es of the pronotum without a tooth on the jxtslerior part of

 /'. Scutcliuni of the vertex moderately broad, but plainly less tiiau the 

 short (male) or long (female) diameter of the eye. Pos- 

 terior femora with the disk of the inner face yellow or red, 

 with three black bands, one apical, one preapical, and one 

 median. The latter may extend, as a stripe, toward the 

 base, but the immediate base is very rarely black. Kai-ely 

 the whole inner face may be suffused with fuliginous, 



obscuring the markings C'rrRiNA group. 



f/\ Disk of the metazone of the pronotum plainly lighter than the 

 prozone, generally reddish brown in color, and smooth, 

 except for a few large, scattered, generally black granules. 

 Posterior femora chiefly red on the inner side. 

 /('. Lower sulcus, as well as the inner face, chiefly red, with no 

 fuliginous suffusion obscuring the fuscous bands or spots.
