third bristle of the second row on the middle segmenta. The 
first abdominal sternite bears severa] hairs at the ventral edge, 
and a curved row on the sides withanumber of additional hairs 
in front of this row. The sternites of segments 4 to 7 bear a 
row of seven or eighfc bristles, and ñve to seven hairs in front, tno 
numbers being rather larger on the sternite of the third segment. 
Lean,— The°mid- and hindcoxae bear two bristles posteriory 
at the apex. The anterior fémur bears about fifteen hairs on 
the outer surfaee and three bristles ventrally before the apex, 
there being on the innerside a row of four or ñve from the apex 
forward. The tnid and hindíemora are also hairy on the outer 
surfaee, and bear a subventral row of hairs on the innerside. 
The last four or ñve ventral bristles on the outerside of the 
hindfemur are long and stand in a regular row. The bristles at 
and near the ventral edge of the mid- and hindtibiae are nume- 
rous, and there are two rows of bristles on the outer surfaee, besi- 
dessome additional lateral bristles from thetífth dorsal pair tothe 
apex. The third dorsal pair is represented by a fine hair. The 
longest apical bristle of the midtibia reaches beyond the apex 
of tire first tarsal segment. The longest bristle of the second 
hindtarsal segment reaches beyond the apex of the fourth 
segment. The hairs on the back of the third tarsal segment 
are numerous. The fifth tarsal segment bears on each side 
three rather slender bristles, the third pair being somewhat 
approxiinate, and there is a fourth short bristle halfway towards 
the apex. The measurement of the tarsi are as follows.

Modijied Segments .—The eighth tergite bears a number of 
bristles above the stigma, and a regular series from the stigma 
downwards, there being in front of this sei-ies an irregular row 
of shorter ones. Near the apical edge thereis a row of about 
fourteen bristles, while on the inner surfaee near the apex there 
are two rows of short ones. The stylet is subcylindrical, being 
about three times as long as broad. 
Length: ^ , 2 02 mm. 
This species comes near to bohld and lutzi, but can easily 
be distinguished by the short rostrum, the frontal tubercle, and 
the row of bristles along the genal edge of the head. 
We iiave of this species one Valparaíso (Chile), from 
Octodon degus, collected by Mr. J. A. Wolffsohn.
