low; 10 with sides largely dark obscure orange. Superior ap- 

 pendages black ; rudimentary inferiors dull yellow. 



Legs light brown, femora each with two more or less dis- 

 tinct darker areas. 



Wings clear or with a very faint tinge of brownish ; stigma 

 black or very dark brown, oblique, covering two to two and 

 one-half cells ; of 30 front wings, 20 have two postquadrangu- 

 lar cells, 2 have two plus, 4 have three minus and 4 have three ; 

 of 30 hind wings, 18 have two minus and 12 have two; post- 

 nodals of front wing are 16 to 20, of hind wing 15 or 16; in 

 the front wing the arculus is distal to the cubito-anal cross- 

 vein about .4 mm., in the hind wing about .3 mm. ; in both front 

 and hind wings the anal vein separates from the posterior 

 border about .4 to .5 mm. distad to the cubito-anal cross-vein. 



Female. — Head similar to that of male, but much duller, 

 rhinarium and nasus more extensively dark. Profile as in the 

 male. 



Prothorax light brown, front lobe black along the front 

 border, wider on either side; middle and posterior lobes pat- 

 terned as in the male, largely dusky. Propleuron light, or light 

 yellowish, brown. 



Thoracic pattern as in the male, but the pale colors are 

 light browm, the two pale stripes on the mesepisternum only 

 more or less yellow tinged ; between these two stripes the mes- 

 episternum is always brown,- black below at the outer border, 

 thus darker than the darkest males in the present material. 



Abdominal segments 1-7 similar to the male, slightly duller, 

 brown rather than black except at each apex; 8-10 brown, 10 

 lighter, 9 with a broad dull yellow oblique ring which is sub- 

 apical in the middorsal line and runs downward and forward 

 ending on the extreme anterio-ventral border; sides of 8 and
