of outer. Armature of forefemur with inner row consisting of alter- 

 nating slightly longer setae and short spines, the setae arising from 

 wartlike bases. First spine of forefemur at nearly two and one-half 

 times its length from tip of trochanter; basal half of forefemur gradu- 

 ally thickened to first spine. 



Abdomen on dorsal aspect widening to apex of third segment; 

 fourth and fifth segments parallel sided, slightly wider at apex of sixth 

 and at base of seventh segments (fig. 94). Hind margin of terga 

 straight; margins of fourth and fifth terga with shallow concavities 

 before lateral angles. Sixth tergum with large hoodlike elevation 

 medianly before hind margin. Seventh tergum four-fifths as long as 

 sixth, shorter than its basal width, trapezoidal; hind margin with 

 broad but slightly produced apical angles and very short median 

 projection; with four round depressions on disc; basal fourth raised 

 cephalad but not reaching upper margin of elevation of sixth tergum 

 (fig. 56) . Eighth tergum narrow, apical margin semicircular, margins 

 and median carina elevated; transversely corrugate. Ninth tergum 

 with median line and margins elevated, transversely corrugate; apex 

 rounded. Hind margin of second to sixth sterna shallowly and broadly 

 concave; of seventh with small median projection. Seventh sternum 

 slightly longer medianly than sixth. 



Overall body length 27.0 mm. 



The hoodlike elevation of the sixth tergum easily distinguishes this 

 species from all others.
