July. The legs of decorata are much paler, 
especially the pubescence of the scopa, and the 
basal joint of the hinder tarsi ; the face and apex 
of the abdomen as a rule are much paler, than in 
bimaculatci. I think all these differences com- 
bined clearly point to two distinct species. 
smithella. Ivirby. One of the very earliest of the 
spring bees. I have taken it in plenty at the 
flowers of the willow, round Norwich and 
Brundall. 
nigriceps. Kirby. The female is plentiful in the 
neighbourhood of the city in July and August; 
generally to be found at the flowers of the 
ragwort. I have taken but one male. 
purescens. Kirby. Mousehold, at the flowers of the 
heath, in August. 
tridentata. Kirby. Mousehold and Eaton; although 
the males are not uncommon at the ragwort in 
July, I have taken but two of the females. 
angustior. Kirby. Very scarce. I have only met 
with a single female on the Ileart’s-ease road, 
Mousehold, on May 25th, 1875. 
fucata. Smith. The Eev. J. L. Brown gave me a 
female which he took at Carbrooke, June 6th, 
1875. I have not taken it myself. 
ArRiLiNA. Smith. Mr. Smith returned my specimen 
with the following remarks : “ I have compared 
your bee with my collection, and find it the same 
as a species taken near Shoreham by the late Mr. 
Walcott, of Bristol, and which I believe to bo 
A. aprilina. Mr. Walcott sent mo both sexes; 
the male sent is certainly A. aprilina. I don’t 
know on what authority he united the sexes, and 
for this reason I have added a 1 to the species.” 
My specimen was taken in April, 1873. 
fulvicrus. Kirby. The Bov. J. L. Brown gave me a 
male he took at Brundall in 1874. 
albicrus. Kirby. Generally distributed and common 
in April and May.
