cance. The honey bee was observed to visit the red flowers 
both when solitary and when associated with yellow flowers. 
Neither was there any preference manifested for yellow 
flowers when flowers of both colors occurred in the same 
cyme. Examination showed that the reddish flowers con- 
tinued to secrete honey abundantly. This is an instance, not 
uncommon, of a flower secreting nectar longer than is neces- 
sary. The stems and leaves are frequently reddish, due probably 
to oxidation, and the reddish color of the older flowers appears 
to be due to a similar change in the nutritive fluids. 
The flowers are proterogynous. Immediately after the 
apices of the corolla separate, the stigma protrudes in a recep- 
tive condition. At this stage the anthers, which are 4 mm. 
long, rest directly against the style, the length of which is 
then 13 mm. and of the stamens 12 mm.; in the older flowers 
the style lengthens to 19 mm., the stamens to 15 mm. The 
anthers dehisce introrsely shortly after the expansion of the 
flower, but as they are shorter than the style, self-fertilization 
is not likely to occur. As the style lengthens it is bent aside, 
and the honey bee was observed to visit flower after flower 
without coming in contact with the stigma. 
The length of the corolla tube (7 mm.) and the fact that the 
anthers are divergent and not in close proximity to the stigma 
indicate that the flower is adapted to bumblebees. The smaller 
bee, Halictus disparalis Cr., 9, was seen to try vainly to reach 
the honey. The most frequent visitor, however, is the honey 
bee. The larva of the hawk moth, Hemaris difinis, feeds upon 
the leaves, and the moth sucks the flowers. Minute flies and 
a beetle were observed feeding upon the pollen. 
Visitors: Hymenoptera — Apida : (1) Apis mellifica L., 9, 
sucking, frequent; (2) Bombus bimaculatus Cr., 9, s.; (3) 
Psithyrus (Apathus) laboriosus Fab., 9, s.; Andrenida: (4) 
Halictus sp.; (8) H. disparalis Cr., 9, collecting pollen; (6) 
Halictulus americanus Ash., 9; (7) Augochlora aurata, Sm., 
9,c.p. None common except the first. 
Lepidoptera — Rhopalocera: (8) Pamphila peckius Kirby, 
s.; Heterocera: (9) Hemaris diffinis, s., standing on a leaf or 
poising on the wing. June 29 to July 6. Waldoboro.
