-wing-apex, this latter narrowest in the t^^pe male ; remainder 

 of tlie wing-surface pi'ovided vith three broad, pale grey 

 cross-bands, as follows : the first just beyond the arculus, 

 occupying most of the basal half of cell 2nd A, in cells li 

 and M narrowly connected with the broad second band 

 which occupies the level of the sector and the end of vein 

 2nd A, beginning in cell Sc, continued to the posterior 

 margin, the thii-d band lies just beyond the cord, narrowest 

 near the dark brown stigma, continued caudad across the 

 wing, occupying about the basal halves of cells Ro, i?^, R-,^ 

 M^, and M^, all but the base of cell Cui anil the tip of cell Ca ; 

 veins brown, a little darker in the grey areas. Venation : 

 almost as in the related E. pennijnetji, l)ut vein Cii^ is less 

 strongly bent near the tip and vein 'Znd A runs closer to 

 the wing-margin at its bend so that cell 2nd A is very narrow 

 at this point. 



Abdominal tergites obscure yellow, shiny, indistinctly 

 darker medially; sternites rather more uniformly yellowish, 

 Male hypopygiutn with the pleurites stout, the inner apical 

 angle a little produced and covered with numerous setigerous 

 tubercles ; two pleural appendages, the outer one straight, 

 the stem slender, the apex enlarged into a globular head 

 that is covered with parallel rows of overlapping, scale-like 

 structures ; the inner appendage is profoundly two-branched, 

 the arms divergent at a straight angle ; the short arm is 

 straight, the long arm recurved just beyond the base so the 

 long apex lies sul)parallel with the short aim; this arm is a 

 little dilated before the aeute tip and here provided with 

 liumerous short appressed hairs. Gonapophyses flattened, 

 the inner angles produced into powerful blackened horns 

 that are directed strongly laterad and thus divergent. Ninth 

 pleurites dark brown basally, the tips brightened.

This beautiful crane-fly is readily told from E. j)eringueyi, 

 Bergroth, the only described species tiiat is close to it, by^ 

 the well-marked diagnostic characters given above.
