P. rhodura @ runs in my table of Perdita (Proc. Phil. 
Acad. 1896) to 71, and is separated from P, Snow?i by the 
pallid venter, marking of clypeus, &c. It most resembles 
P. crotonis, especially in the colour of the abdomen, but 
differs at once by the face-markings, granular mesothorax, &c. 
P. rhodura & runs in the table to 12, but is quite distinct 
from P. chamesarache, to which it comes nearest.

? .—Length about 5 millim. 
Thorax small; head and thorax very dark bluish green, 
almost black; front microscopically tessellate and sparsely 
punctured ; face wholly dark; clypeus black, with strong 
sparse punctures, wanting in the middle; labrum and man- 
dibles wholly dark; antenne piceous, flagellum light brown

Hab. Embudo, Sept. 25. One. 
P. subfasciata runs in my table of Perdita (I. ¢.) to 19, but 
is quite different from P. mentzelie. It is not unlike P. eneé- 
jrons, but differs at once by the bands on the abdomen &e. 
The only other Perdit: taken at Hmbudo was P. zebrata, 
Cress., one at flowers of Cleome serrulata, Sept. 26. 
Andrenidez. 
Andrena vulpicolor, sp. n.

antenne black ; face rather thinly clothed with orange hair ; 
cheeks densely clothed with orange and occiput with bright

broad ; clypeus granular and with large punctures; sides of
