6. Palpi black, unbanded, longer than the proboscis by 
nearly the whole of the last two joints. Abdomen with traces 
of basal white bands. Fore and mid ungues unequal and 
uniserrated, hind equal and simple; apices of the fore and mid 
tibiae expanded (1). | 
Length.—3°*5 vom. 
Habitat.—Para, Brazil (Dr. Durham). 
Observations.— Described from three females and a’single male. 
I am not sure if this is the male of this species, but they occurred 
in the same box ; I cannot, however, separate it satisfactorily 
from the male of M. humilis. The females can at once be told 
from the other species of this genus by the unbanded and 
unspotted abdomen.
