pieces triangular, almost or entirely united on the ventral aspect; pleu- 

 ral pieces elongate-cylindrical, bearing two appendages, the lower one 

 (c), a long, chitinized hook bent strongly ventrad near its middle; 

 the dorsal appendage (b), long, slender, fleshy, projecting caudad. 

 Viewed from beneath, a short rectangular organ (f), ending in two 

 short sharp-pointed, chitinized teeth which are curved ventrad; the or- 

 gan rather chitinized basally and on the sides ; behind the above de- 

 scribed apophyse, an elongate subchitinized organ (g), vmdoubtedly 

 the penis guard; it is elongate-cylindrical and directed caudad; above 

 this, a pair of sharp pointed chitinized teeth (e), directed caudad and 

 slightly upward, their base thickened and with a dorsal notch. $ ,

Trochanter and femur dark brownish-black, extreme tip of latter 

 white. Lower pleural stripe narrow, only about one-third as wide as 

 the pale one above it. Pleural stripes usually light^ brown, not 

 clear cut. Wings with cord and outer end of cell 1st M' dark brown,

 (see fig. 2) : the eighth sternite convex, basal piece of ninth ster- 

 nite triangular; pleural pieces (a), cylindrical, with a short, fleshy 

 dorsal lobe (b), clothed with long hairs at the tip; ventral lobe reduced 

 to two blunt chitinized teeth (c) ; behind this a broad, less chitinized 

 organ (d) Viewed from beneath, a short, broad, rectangular organ 

 bearing at its apex at either angle, long curved horns (e), shaped like 

 steer's horns, chitinized at the tip: ventrad of this organ, close to its 

 lower face, two sharp needle-like appendages (f), and a sharp-pointed 

 median organ which is presumably the guard of the penis (g). 5,
