ment ; ninth dorsal segment of the male hardly shorter than the seventh, 

 slightly inflated, hardly at all expanded, apical margin arcuato-emargi- 

 nate ; supra-anal plate of the male very short, obtuse-angulate, carinate ; 

 cerci slightly longer than the ninth dorsal abdominal segment, rounded, 

 well curved inward toward the median line, the apical portion slightly 

 bent, thickened and blunt, a slight, moderately acute spine at the internal 

 base, eighth ventral segment quite short, not reaching to the apical mar- 

 gin of the eighth dorsal segment ; subgenilal opercule elongate, reaching 

 to the apex of the ninth dorsal segment, narrow, the apex "spout- 

 shaped," the margin bent on itself then somewhat expanded and shal- 

 lowly emarginate at the apex, the lateral margins of the terminal portion 

 of the plate arcuate when seen from the side. Seventh dorsal abdominal 

 segment in the female, about half as long as the sixth ; eighth dorsal seg- 

 ment slightly shorter than the seventh ; ninth dorsal segment nearly twice 

 the length of the eighth, compressed, slightly carinate dorsad at the apex, 

 the apical margin with a rectangulate median emargination, which ex- 

 poses the rotundato-angulate supra-anal plate ; cerci nearly half the length 

 of the ninth dorsal segment, lanceolate-conic ; subgenital opercule pro- 

 duced, reaching to the apical margin of the eighth dorsal segment, com- 

 pressed, subequal, the apex rectangulate. Limbs very long and slender 

 in the male, the median femora inflated much as in D. calcarata, the 

 limbs in the female much shorter and more robust. Cephalic femora of 

 the male slightly longer than the pronotum and mesonotum together, 

 tibiae slightly exceeding the femora : median femora about equal to the 

 metanotum without median segment, tibiae distinctly longer than the 

 femora ; caudal femora reaching to the apex of the fourth abdominal seg- 

 ment, tibiae distinctly longer than the femora. Spine on the median 

 femora of the male very stout ; the carinae regularly but not very strongly 

 serrato-dentate ; ventral carinae of the tibiae rather strongly serrato- 

 dentate ; spine on the caudal femora slenderer and more acute than on 

 the median femora, the carinae of the caudal femora and tibiae serrato- 

 dentate as in the median limbs but in a less decided manner. Cephalic 

 femora of the female about equal in length to the pronotum and mesono- 

 tum, tibiae slightly longer than the femora ; median femora about equal 

 to the metanotum with median segment, the tibiae equal to the femora ; 

 caudal femora reaching to the middle of the fourth abdominal segment, 

 tibiae subequal to the femora. Spines on the median and caudal femora 

 of the female much smaller than in the male, but of fair size. 



General color of the male ochraceous, becoming pale oil green on the 

 cephalic limbs, median and caudal tibiae. Apex of the abdomen prout's 

 brown ; eyes seal brown ; a narrow postocular bar bistre. General color 

 of the female seal brown, becoming wood brown on the head, prothorax, 

 cephalic portion of the mesothorax and on the apex of the abdomen, the 

 femora and tibiae somewhat mottled with the two shades, eyes burnt 

 umber.
