individuals. The Colletidae, Halictidae and Apidae, 
about 8.3% of the families, made up 57.9% of the indi-

SCROPH ULARIACEAE. 
InysantHEs GranprFrtora, Ma., R.—The flower is blue, 
the lobes more or less white, especially at the tips. The 
upper lip is small and cleft, the lower spreading, with 
three large rounded lobes. On the lower wall of the 
corolla the filaments of the two lower sterile stamens form 
two ridges which are covered with yellow pollen-like 
glands. The filaments have about the middle an awn- 
like process. 
The stigma lies under the upper lip. The two fertile 
anthers are coherent and lie on the upper wall about 2 
mm. below the stigma. In this position self-pollination is 
fairly impossible. The insect’s tongue touches the stigma 
before the anthers. The stigma is sensitive and closes 
after contact. 
When the tongue touches the anthers and is withdrawn, 
it turns back the lower lobe of the stigma and closes it. 
The tube is narrow, rendered more so by the sterile 
filaments, perhaps entirely excluding short tongues and 
requiring long tongues to incline to the opposite side
