A Bombus which I have not yet determined. and may call 
Bombus A, was seen at 7,000 ft. on the flowers, going diligently 
from one to another, 
ScureELLARIA LINEARIS, Benth. 
The flowers are in spikes and are conspicuous, but are not 
raised above the short grass of the dry slopes where the plant 
flowers in April and May. They are rose-pink with a yellow 
ng. 
Observations were made on the “ae north and west of 
Simla, on both sides of the Snutlej valley. 
The tube is 11—15 mm. long, rather narrow in the lower half, 
and slightly curved at the very base: in the upper half it. broad- 
ens into the two lips. The lips are pressed very close together so 
that the tube is closed. There is no other obstruction to the 
tongues of insects, beyond the compression of the lips. The flower 
is intended for the visits of Bombi, which are strong enough to 
open the lips and adept enough to know how to get the honey. 
With their feet on the well-marked landing stage they have to 
): on raising the hood the stigmas and anthers become exposed 
and the hood again returns over them when the lifting pressure is 
removed. These palatal plates are invaginations of the hood 
ag the lobe which is seen at the base of. the upper lip in 
g. 
The outside of the corolla is covered by fine hairs: the calyx 
hardly protects the tube at all at the base. Bombus hsemorrhot- 
dalis bites every flower that it visits. It settles on the lower lip

to dusk ; and almost every flower examined: had been robbed thus.
