 slender at base; joint 2 shorter than any of the next four; joint 5 

 longest and broadest (fig. 21, a) . Clypeus with two large setae each 

 side. Labrum nearly continuous with the clypeus, a series of 14 

 short setae across base. ISIandibulary stipes slanting inward and

FiGUEB 21. — Leiodere dasyura, new genus and species : a, Antenna ; &, gnathochilarium ; 

 c, head and first five segments, lateral view ; d, anterior gonopods, anterior view. 



First segment with the dorsum tvvo-thirds longer than the lateral 

 margin and longer than the next three segments together; anterior 

 corners rounded and somewhat produced forward; lateral margin 

 nearly horizontal, with a raised rim; hind angles squarely rounded, 

 scarcely curved under the sides of the body ; posterior margin straight 

 its entire length; lateral surface with 5 to 10 striae directed forward 

 from the back margin just above the angle, the lower striae longest. 

 Anterior segments shown in lateral view in figure 21, c. 



Segments 2, 3, and 4 strongly constricted, necklike; the back 

 margin of segment 4 only three-fourths as wide as the broadest part 

 of segment 1 ; segments 2 and 3 with the dorsum flat, without trans- 

 verse constrictions; segment 4 with the constriction evident, the 

 anterior subsegment exposed and the posterior subsegment much more 

 convex but lacking the swellings of the ensuing segments.
