than 4 and 5, about 2.1 times as long as wide; 7 oblong, briefly 

 pedicellate, truncate at apex, about twice as long as wide ; 

 8 about 1.4 times as long and half as wide as 7, conical, nearly 

 three times as long as greatest width; antennas uniform dark 

 blackish brown (nearly black) except pedicels of segments 

 3-6, which are yellowish ; sense cones : 3, 1-2 ; 4, 2-2 ; 5, 1-1+^ ; 

 6, 1-1+^; 7 with one on dorsum near apex. Mouth cone long, 

 pointed, attaining mesosternum, the acute labrum surpassing 

 labium. 



Prothorax about half as long as head and (inclusive of 

 coxae) about 2.7 times as wide as long; pronotum reticulate, 

 less distinctly so in front of middle, the lines less heavy than 

 on head, anterior and posterior margins concentric ; all usual 

 bristles present, expanded apically ; anterior marginals short- 

 est, half as long as the posterior angulars which are the long- 

 est ; anterior angulars and posterior marginals about equal in 

 length, slightly shorter than posterior angulars ; coxal and mid- 

 laterals about equal in length, longer than anterior marginals. 

 Pterothorax very slightly wider than prothorax. Wings 

 clouded with brown, more darkly at base and middle; fore 

 pair with 12 or 13 accessory hairs. Legs moderately slender; 

 fore tarsus with a long and nearly straight tooth. 



Abdomen very slightly broader than pterothorax. Tube 

 0.6 as long as head, about 2.4 times as long as greatest sub- 

 basal width, which is about 1.8 times the apical; sides diverg- 

 ing in basal sixth, thence abruptly converging for a short dis- 

 tance, concavely tapering to apical fourth, which tapers a little 

 more distinctly to apex. Lateral bristles spatulate at apex, almost 

 colorless ; segment 9 with the lower lateral pair pointed and 

 the upper lateral and dorsal ones dilated at apex; terminal 

 bristles brown, nearly 1.5 times as long as tube.
