reaching base, a continuous stripe on their femora above, a short, broad stripe 

 at base beneath, a small spot beneath near apex, transverse band on inner side 

 near apex (which is ferruginous), and a short stripe on their tibiae on each side 

 near apex, yellow ; posterior femora with four large blunt teeth and two small 

 ones, sometimes obsolete, towards base; abdomen shining, black, pointed at 

 apex, a band on second, and the following segments more or less yellow ; petiole 

 short, stout, black. Length .35 inch. 



% . — Face spotted with yellow ; posterior coxae with a short slender yellow 

 stripe on each side near apex; abdomen smaller, the band on the second and 

 the following segments orange-yellow; otherwise like J. Length .30 inch.
