I have often seen butterflies at work upon this orchid, and have ob- ser\-ed their tongues generously decorated with the glands and rcnmants of the pol- len ina;scs. The series of dia- grams (Fig. 14) will, I think, fully demon- strate how this blos- som utilizes the but- terfly. At A we see the insect sipping, its tongue now in contact with the elonoated disc, which adheres to and clasps it. The withdrawal of the tongue (B) removes the pollen from its pouch. At C it is seen entirelv free and up- right, from which position it quickly assumes the new attitude shown at D. As the tongue is now inserted into the subsequent blossom this pollen mass is thrust against the stigma (E), and a few of the pollen grains are thus with- held upon its viscid surface as the insect de- parts (F).
