The epimerum has 2 rows of 4 bristles each, with 1 large one at the 

 the apical margin. 



Abdomen.— The first abdominal tergite has 2 rows of 10 bristles 

 each, the posterior being comprised of the larger bristles. The next 

 6 tergites have 2 rows of bristles each, a posterior of large bristles, 

 about 12 in number, and an anterior of smaller bristles, also 12 in 

 number. On the apical edge of the metanotum there are 2 small 

 teeth on each side. The first abdominal tergite contains 3 such teeth 

 while the second and third have 1 each on each side. At the apex 

 of the seventh tergite in the female there are 4 antipygidial bristles, 

 sometimes 5. The male has but 3 antipygidial bristles. The ab- 

 dominal sternites from the third to the sixth have a single row of 6 

 bristles. The seventh has a row of about 16 bristles. 



Legs. — The fore coxa has about 32 large bristles more or less regu- 

 larly disposed in 6 oblique rows. The hind coxa is without teeth on 

 the inner surface. The mid femur is without bristles on its lateral 

 surfaces. The hind fenmr is also without a row of bristles on its 

 lateral surfaces. The spines on the posterior border of the tibia are 

 single and in a close set row. The apical spines of the second tarsal 

 joint of the hind legs are shorter than the third joint. The last 

 tarsal joint on all the legs contains 4 lateral spines and a subbasal 

 pair situated between the first lateral pair. 



Modified segments. — ( 9 ) Just beneath the pygidium is 1 long 

 bristle. On the eighth tergite there is a patch of hairs, 6 of which 

 are on the apical margin and about 5 or 7 anterior to these. The 

 stylet is short, almost as wide at the base as at the tip, where there 

 is a long hair. Posteriorly to this bristle there springs another one 

 from the under surface. 



( cf ) Manubrium of the claspers is narrow, curved at the tip. The 

 finger reaches to the level of the process, has a stout pedicle, is flat 

 on its anterior border, and is decidedly convex on its posterior border, 

 where there are 4 bristles. The shape of the ninth sternite is shown 

 in the figure.
