metanotura without impressed line; abdomen fusiform, very much 

 broader in middle than at ends; legs very long and slender, hind 

 tibia with the inner spur not one half length of the basitarsus. Wings 

 slightly fumose, third submarginal cell much longer than broad, but 

 not much narrowed above, recurrent veins meeting cells at middle; 

 basal vein slightly bowed at base and interstitial with the transverse. 

 Length, 8 mm. 



Resembles A. birkmanni, but differs in having a very distinct 

 impressed line on the face from antennae up to ocellus, in the more 

 fusiform abdomen, and in the shorter spur to hind tibia. 



Ageniella minuscula, sp. nov. 



Type.— M. C. Z. 10,026. Texas: Dallas, 2 August. One speci- 

 men. 



cf Black, with silvery pubescence. Abdomen reddish on side of 

 first segment, legs mostly pale, with whitish spurs; wings subhyaline. 

 Body slender; head short and fairly broad, vertex high, convex, no 

 line from antennae to ocelli; the pronotum rather long, arcuate 

 behind, raetanotum without groove; abdomen slender, not much 

 enlarged in middle, polished; femora and tibiae mostly reddish, long 

 spur of hind tibiae more than one half of the basitarsus. Wings 

 short, slender; marginal cell acute, much beyond third ubmarginal 

 cell; second submarginal short, third very short, outer side convex, 

 recurrent veins meeting cells at middle, basal vein bowed near base, 

 arising a little before the transverse. Length, 4 mm. 



Agreeing in general with the northern A. Unella but it is much 

 more slender and has a more arcuate margin of pronotum separating it.
