it there is a wide notch for the reception of the distal segment 
of the movable dactylus, which closes upon the proximal 
segment almost as the blade of a pocket knife does upon its 
handle. 
Q. Legs in hinder half of body of normal length and form. 
Like the 7 in other respects. 
Vulva (fig. 6, F) somewhat heart-shaped; the cap very large ; 
internal and external borders sloped distally to a blunt ter- 
mination. 
Length 13 mm. 
Locality; Rangoon. Several specimens collected by Mr. E. W. 
Oates. 
This is a very remarkable form owing to the high speciali- 
sation of the male. It is the only Asiatic species of the family 
which is furnished with a stridulating organ resembling that 
which is characteristic of the S. African genus Spherotherium. 
In Spherotherium, however, the principal stridulating plate is 
attached to the carpal segment, whereas in this species of 
Zephronia the plate is supported by the movable dactylus. The 
curious elongation of the posterior legs in the male is quite 
unlike anything that has hitherto been described. 
In size, colour, ornamentation etc. the species very closely 
approaches both Z. comotti and Z. gestri.
