the finger we cannot make out. x\.bove the large ñap there 
appears a small stylet-like process, the homology of which 
is unknown to us; it is in the same position on both sides 
of the specimen, and seems to project from the inside of 
the large flap. The manubrium is broad and curved 
upwards, its apex being pointed. The ninth sternite is 
partly concealed by the clasper. The ninth tergite bears 
a strong bristle at its apical edge. The lateral portion of 
the tenth tergite is rounded off distally and is covered 
with minute hairs, this sclerite being apparently separa- 
ted by a suture from the dorsal central sclerite of the 
tenth tergite. 
Female. The eighth abdominal tergite is emarginate at 
the apex. There are about four long bristles from the ven- 
tral apical angle inwards and about as many on the upper 
half of the lateral surface, besides numerous small brist- 
les which are placed on the lower half of the lateral sur- 
face. 
The anal tergite (=:tenth tergite) has one long bristle. 
The stylet is nearly three times as long as it is broad at 
the base. 
Length, male 2 mm., female 2.7 mm. 
We have one male and three females from Valparai- 
so, Chile, off Akodon OUvaceiis, Akodon Longipilis, and 
Phyllotis Darwini, collected by Mr. J. A. Wolffsohn.
