line of the abdomen. There are also two rows of bristles on each 
segment. Sternites III-VII bear bristles as follows: 2, 2, 2, 3, 
6; the same figures repeated for the opposite side of the insect. 
Legs.—The anterior margin of the fore tibia bears six groups 
of two bristles each. The mid and hind tibiz have seven groups 
each, the third group being reduced to one bristle in each case. 
The longest apical bristle of hind tibia does not reach the apex 
of the first tarsal segment, but the longest apical bristle on both 
fore and mid tibiz exceed the first tarsal segments of those legs. 
The comparative measurements of the tarsal segments are as 
follows: 
Tarsus. Segments I-5 
I 15 16 14 1 30 
II 30 25 18 Ta Dy 
III 65 45 30 20 30 
Modified Segments.—The seventh sternite is continued posteri- 
orly at the ventral angle and its posterior margin is distinctly 
sinuate. The process of the eighth tergite is more or less trian- 
gular and bears on its superior margin four and on its inferior 
margin two heavy bristles. At the cephalad end of the inferior 
margin there is a brush of about six long flexible bristles. The 
stylet is cylindrical and bears at its apex one stout bristle. The 
eighth sternite bears eight long bristles and two short spines near 
the upper margin. The receptaculum seminis is large and oval. 
The juncture of the appendix with the body is poorly defined, 
the appendix at the base being the same diameter as the body. 
_Length—2 mm. 
Specimen described is one of a series of both sexes taken on 
Plummer Island, Maryland, off Blarina brevicada Say., March

Myodopsylla subulata sp. nov. 
& Head.—The entire upper part of the frons is transparent 
and bears but three minute bristles near the antennal groove. 
The line of chitinization runs from the base of the posterior 
genal spine in a gentle curve to the upper fifth of the anterior 
margin of the antennal groove. On the dark (chitinized) part 
of the frons there are five stout bristles along the antennal groove
