 pygium with the ninth tergite almost straight across the caudal margin; 

 pleurites rather short, shorter than the apical lobes; ventral inner 

 side of the pleurite produced entad into a complex lobe which is 

 expanded at its apex and bears at the inner margin a lateral cylindrical 

 lobe with long hairs. Dorsal apical appendage a chitinized rod almost 

 straight basally, toward the tip slightly bent inward and acutely pointed; 

 ventral apical appendage a large fleshy lobe whose inner margin sub- 

 apically is produced into a long, slender, cylindrical, chitinized point, 

 rather blunt at the apex and here with a few hairs; at its base on the 

 outer side with two sharp chitinized spines which are directed back- 

 ward. Anal tube short, very broad, projecting slightly beyond the 

 caudal margin of the ninth tergite, its apex feebly concave. Penis

Holotype, d', Olympus, Oahu, September 8, 1912 (O. H.

Allotype, 9 , with the type. 



This interesting little species is dedicated to its collector, 

 Mr. O. H. Swezey, to whom I am indebted for many favors. 

 It is apparently related to D. foliocuniculator Swez., but is 

 readily distinguished by its very small size, uniform pallid 

 coloration, and the open cell 1st M2.
