 times as long as the fourth; the third nearly two-thirds as long as 

 the second. The first three segments are relatively longer than in 

 the male. 



Subriitois. — The male has the intercoxal process of the first ventral 

 segment just noticeably transverse, and tlie post-coxal j)art is scarcely 

 as long as the second ; the third is slightly less than twice as long as

The female has the intercoxal process slightly transverse, and the 

 post-coxal portion of the first is about equal to the second in length; 

 the third is about three-fourths as long as the second and about twice 

 as long as the fourth. 



Goryi. — The intercoxal })rocess in the male is distinctly transverse, 

 and the post-coxal part of the first segment is scarcely as long as the 

 second, the latter being about one-fourth longer than the thii'd; the

The female has the intercoxal salient strongly transverse and about

 second and about twice as long as the fourth. 



jSfrioJat((. — In this species the male has the intercoxal process trans- 

 verse and rather short, about equal to the fourth in length; the post- 

 coxal part of the first ventral segment is about as long as the second, 

 and the fourth is scarcely one-half as long as the latter. 



The female has the intercoxal process moderately transverse and 

 scarcely as long as the third segment, and the post-coxal part of the 

 first is nearly as long as the second; the third segment is about three- 

 fourths as long as the second, and the fourth is nearly two-thirds as 

 long as the third. The first three segments are comj^jaratively long. 



Fvdf(yrwif(. — The intercoxal i)rocess of the male is distinctly (juad- 

 rate and equal in length to Ihe post-coxal part of the same segment, 

 which is su})equal in length to tiie third; the second is about twice as 

 long as the fourth segment. 



The female has the segments proportioned about as in the male, 

 but slightly longer. The intercoxal process is quadrate. 



Ofaca. — The male has the intercoxal salient short and slightly 

 transverse, the post-coxal portion is ecpial in length to the third and 

 the second is about twice as long as the fourth.
