continued downward by a very fine brown line ; a brown point near 

 the lower end of the mesepimeron ; a small black spot at nearly mid- 

 length of the obsolete first lateral suture ; a short black mark at the 

 upper end of the second lateral suture. 



Abdominal segments 1-3 chiefly blue, with the following black : a 

 square dorsal basal spot on 1, the intersegmental articulations between 

 1 and 2 and 2 and 3, a short isolated transverse band on the dorsum 

 of 2 at two-thirds' length, and the hindmost sixth of 3. Dorsum of 

 4-7 dark brown, becoming black at the hind end of each segment, a 

 narrow transverse basal ring on each and the sides inferiorly blue ; 

 8-10 blue, hind margin of 10 with a median dorsal, almost semicircu- 

 lar, excision, reaching more than half-way toward the anterior margin 

 of the segment, edges of the excision only slightly elevated, presenting 

 the appearance in end view of a low truncated process slightly bilobed. 



Superior appendages in dorsal view wider than long, shorter than 

 10, bifid at apex, branches of equal length, outer branch with a more 

 acute tip, inner branch applied against the inner branch of its fellow 

 of the opposite side, the surface thus in contact black, while the rest of 

 the appendage is pale blue ; in end view the inner branch is much 

 higher than the outer, and is easily recognized by its black contact- 

 surface just mentioned ; in profile view each superior appendage is 

 directed slightly upward ; upper and lower edges straight and slightly 

 divergent, the apparent apex being formed by the moderately convex 

 black posterior margin of the inner branch, on which is silhouetted the 

 acute pale blue tip of the outer branch. Inferior appendages project- 

 ing caudad about twice as far as do the superiors, thick at the base, 

 tapering to the subacute tip, which is directed upward and but slightly 

 toward its fellow of the opposite side. 



Legs pale blue, femora with a superior blackish band. 



Wings clear, stigma rhomboidal, blackish, its costal edge longest ; 

 front wings with 10-11 postnodals ; hind wings with 9 postnodals ; 

 M 2 arising nearest the fourth or (one wing) fifth. 



Dimensions: Abdomen 25.5; hind wing 15. 5-16; width of head 

 3.68 ; width of one blue postocular spot .64 ; maximum height of 10 

 .92; height of 9 at base .96 ; width of tip of dorsal process of 10 .36 ; 

 maximum width of 10 .64 mm.
