Inhab. Indiana. 
Body somewhat depressed : head black-piceous, polish* 
ed : antennm yellowish towards the base : palpi^ penuiti* 
mate joint rather dilated ; ultimate joint very short, conic, 
hardly one fourth as long as the preceding : thorax honey

shorter than in our other species. 
Much reform seems requisite in this & the preceding 
genera.
