The metaparameres are much shorter than the proparameres, 

 slender and gently curved, the tips turned in and bilobed ; in the 

 preputial sac are to be seen what appears to be the endless coils 

 of a long virga, with chitinous indurations. 



Sub-family 2. Diplatyin^e. 



Very marked characters are afforded by the genital armature 

 in this group. Zacher only knew a few species, and so his pro- 

 posed arrangement is extremely incomplete. The examination of 

 a number of additional species has shown that there is a great 

 diversity of structure in the genitalia of the Diplatyinx, but it is 

 yet premature to base the classification of the sub-family upon 

 these characters. I have therefore refrained t'rum erecting a host 

 of new genera for every shape of penis and virga, and have retained
