and the organsare exposed. Afterwards, they return into the 
galea. The flowers are proterandrous. Two lateral lobes of 
the upper lip and two streaks on the lower are white, forming 
pathfinders. The tubes are about 14 mm. deep. The flower 
seems to depend mainly upon our common long-tongued bum- 
ble-bee, Bombus americanorum F. 4, which visits it for honey 
and pollen.’ It is also visited for honey and pollen by B. vir- 
ginicus Oliv. 3, and for honey by Lxoprosopa fasciata Mcq. 
and by Pamphila zabulon B.-L. 
On Aug. 7, I noticed three little bees, Augochlora pura 
Say 9, Halictus confusus Sm. 9 and Z. stultus Cr. 9, sucking 
at holes near the base of the tube on one side. I suspected that 
the perforator was Odynerus foraminatus Sauss., the same in- 
sect which perforates the flowers of Monarda fistulosa and 
Bradburigna and Pentstemonlevigatus. After waiting awhile 
I was rewarded by seeing this wasp return to the plants and cut 
several new holes. As in the cases above, I only noticed the 
insect making new holes and not using the holes already 
made. 
This plant was observed on 4 days, between Aug. 3 and 26. 
It is common and blooms from July 11 to Sept. 19. 
Scutellaria versicolor Nutt. — The stems rise from 3 to 6 
dm. and bear a few racemes of blue flowers. The lower lip 
is white dotted with purplish. The corolla is about 19 or 20 
mm. long, its tube being narrow and measuring about 15 or 
16 mm. Pollen is dusted upon the upper side of the bee’s 
head. There are only a few flowers open on each plant at a 
time, so that, although crossing between flowers of the same 
plant may occur, it is much more likely to be between flowers 
of distinct plants. The flower is visited by Anthophora 
abrupta Say. It is common and blooms from June 20 to 
July 15. 
Brunella (Prunella) vulgaris L. — ** Fields and borders of 
copses, “Newfoundland to Florida, and west to California 
and northward; evidently indigenous in some of the 
cooler districts. (Eu. Asia, Mex.) ’’— The flowers approach — 
the typical form, the anthers being protected by the galea.
