Deducting the cases where more than one irregularity occurs on one wing we have 271 irregular drone wings and 37 worker wings. Leaving out of consideration those cases in which merely a bend is recorded there are 206 irregular drone wings and 30 irregular worker wings or almost seven times as many for drones as for workers. The figure and these tabulations make clear what has been said previously about an area of irregularity in the wing. This region is rather well defined and no irregularities in venation were seen outside it. A point which may well be recorded is that none of these veins.
