near Dripping Spring, Organ Mountains, the flowers were visited by 
Augochlora neglectula, Ckll., and Halictus lusorius, Cresson, var. These 
are short-tongued bees.

Ckll., two males; Halictus subobscurus, Ckll., one ferale; and 
Halictus sp., four females.

flowers :—Apis mellifera, several ; Pyrameis cardut, many ; Diabrotica 12- 
punctata, one, eating the petals. I do not find pear-blossoms at all attrac-

recorded many insects from the flowers of this plant. The following are
