iridescent tints in certain lights ; the nervures and tegule black ; legs 
black, the apex of the femora, the tibiee and tarsi above of the anterior 
legs, and the apex of the femora and last joint of the tarsi of the 
intermediate and posterior legs orange-fulvous ; claws black toothed 
below, the inside of the tibize and tarsi of the posterior legs clothed 
with a rich golden pubescence ; abdomen black, with obscure blue 
tints in certain lights, coarsely pitted, the posterior margins of all 
the segments smooth and shining, the 1st segment truncated ante- 
riorly, the 2nd segment remarkably long and broad, nearly twice as 
long as the rest 6f the abdomen. 
I procured this insect in the Tavoy forests in October on the 
flowers of a species of vetch growing near a village. It seems 
rare as I have not since come across it in any of the forests in South 
Tenasserim.

This handsome species occurs all over lower Burma and Tenasserim 
up to 4,000 feet elevation. It is remarkable as being purely crepuscular 
in habits. I have never seen one out in the day time. Like the rest 
of the genus it affects flowers, and at Pegu in May and at Amherst 
in December I have caught numbers coming to the flowers of 
the Quésqualis creeper in the brief dark twilight of these regions. 
It not uncommonly flies during the night on moonlight 
nights, making a loud humming. I have found the nest which 
is similar to that made by other species of the genus, and consists of 
a series of round cells hollowed out in the end of a decaying log. The 
egos seem to be laid at long intervals, as some of the cells of a nest I exe 
amined contained a mass of pollen with one egg deposited on it, others 
larvee, and others again the bee in almost all stages of development.
