Abdomen, tergites yellow with an indistinct light brown

Several specimens of this interesting species were included in 

 I lie collection. 



Male.— Length 10.8—11.8 nmi. : wing 10.2—12.4 mm.; 

 antenn;e 4.6 — 1.9 mm. 



Female. — Length 14.4 mm.; wing 13 mm. 



I give a figure of the sixth antennal segment in plate XI, figure 

 10, and of the wing-venation in plate XI, figure 4. The male hypo- 

 jiygium may be described as follows: The 9th tergite from a!30\e 

 (plate XI, figure 9) with the caudal margin having a bread rounded 

 metlian notch into which the tips of the apical pleural appendages 

 fit, the inner edge of the adjacent lobe produced into chitinized 

 lobules which are pro\ided with denticuhe; each lobule with a 

 sharp chitinized point on its caudal margin, these points directed 

 caudad. In a small cf (Vial 46) the median notch is not so rounded, 

 more oval, the sharp caudal points are longer. .Apical appendages, 

 the outer fleshy lobe rather broad and pointed, inner lobe with a
