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), undoubtedly 

 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. $ ,

 Fig. 4. Ventral aspect. Lettering as in Fig. 2. 



amazona sp. n. (Surinam, E. Brazil). 



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, 

 narrowly seamed with darker. Base of flagellum pale. Hypopygium 

 (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). $,
