 short and blunt, not reaching back to the hamular folds ; hamular 

 processes short and very broad, directed mesad, the cephalo-ventral 

 surfaces flat, caudo-mesal margins arcuate, apices bluntly obtuse- 

 angulate with no indication of a tubercle, hamular folds continuous 

 with hamular process not so closely approximate behind as in 

 clepsydra or allied species ; margins thickened, outer margins 

 parallel; color pattern as in Fig. 38, No. 2; anal appendages as 

 in Fig. 33. 



Female. — Head : distance from caudal margin of the vertex to 

 the frontal vesicle about 3.5 mm. 



Thorax : supratriangular space of wings with 2-3 cross-veins ; 

 distal margin of the anal loop as long as the proximal margin of 

 the triangle ; wings very slightly flavescent at base and along the 

 costal margin. 



Abdomen: nearly five times as long as the thorax; superior 

 anal appendages 7 mm. long by 1.5 mm. wide, widest before the 

 middle and tapering from the widest point to a blunt-pointed apex ; 

 ovipositor large, the basal plates not bilobed ; lateral plates visible 

 for about half the length of segment 9; lateral gonapophyses 

 broad, not flattened or sulcate beneath, and with a pencil of hairs 

 at tip beneath the styli; styli 1-1.5 mm. long, being about the 

 length of the dorsum of segment 10. 



Measurements: total length, male 72, female 71 mm.; length 

 of abdomen, male 47-52.5, female 45-54.5 mm. ; length of hind 

 wings, male 45.5-49 mm., female 44-50.5 mm. ; width of hind 

 wings, male 13-14.5, female 12-14.5 mm.

Adult, male. — Color dark brown, marked with green and blue. 



Head: line of contact of the compound eyes longer than the 

 vertex; T-spot of the front with a very wide cross-arm and the 

 upright expanded at base. 



Thorax : wings with anal triangle two-celled ; distal side of the 

 anal loop equal in length to the proximal side of the triangle ; 

 lateral thoracic stripes (Fig. 34) of the mesepimera 1.5 mm. wide 

 below, the upper half considerably narrower. 



Abdomen : first segment without a distinct ventral tubercle ; 

 length of abdomen 4 times that of the thorax; abdominal spots 

 blue (arranged as in Fig. 38, No. 5) ; superior anal appendages 

 (Fig. 34) flat, the tips acute and slightly decurved, a dorsal carina 

 present on each ; length 5 mm. ; greatest width i mm. ; inferior 

 appendage triangular, 2.5 mm. long by i mm. wide at base; pro- 

 vided with 2 minute recurved, approximate teeth at the apex.
