Pronuba yuccasella pollenizes in the Eastern States the blossoms of the common Yucca filamentosa, and on the Western plains it performs the act for the blossoms of Yucca angusli/olia. Yucca brnifolia is pollenijed by Prmuba syntbilica. Yucca KhippM is pollenized by Pronuba maculafa. No doubt there are other species of Yucca which will be ultimately discovered to have species of Pronuba which are adapted in their organs to the work of poUcnalion according to their peculiar requirements. The larva of Pronuba, after it has attained to full siie, drops to the ground, having three pairs of thoracic legs, which enable it to move about and burrow into the earth, it then undergoes transformation into the pupal state. The chrysalis, which is depicted in Fig. 363, has the hacl< armed with peculiar spinous processes, which enable it to malie its way through the loose soil. The student who desires to become fully acquainted with this interesting chapter in insect life must consult the altogether admi- fio. 263. -.
