ON NEW AND LITTLE-KNOWN HYMENOPTERA. 389 
This, one of the brightest coloured of the humble bees, I have found 
fairly common at elevations over 3,000 feet. The type specimen was 
from Moolai, a well-known peak in the Dawnat range. 
The females procured by me are somewhat larger than the one 
described by Smith. My specimens measure length 23 to 28 mm 
(103 to 13 lines), expanse 47 m.m. 
The workers are much smaller ; length 13 m.m., expanse 29 m.m. 
They closely resemble the 9, the colours being perhaps a little duller. 
I have found the nest. It was placed in a hollow under the roots 
of a bamboo bush on the Taoo Plateau (4,000 feet), and resembled 
exactly the nests of the humble bees that I had so often, as a boy, 
taken at home in the deserted nests of field mice.
