conspicuous blunted tooth-like process. 2 nd pair with the movable 

 finger externally convex, and bearing a distinct, small, nodular di- 

 stal segment; on the inner surface the proximal half gives rise to a 

 membranous tooth-like lamina which corresponds with a similar lamina 

 on the inner surface of the immovable dactylus, immovable dactylus 

 smaller, slightly shorter and externally less convex than the movable 

 dactylus. 



9 — Anal tergite like that of male; apical antennal segment slightly 



smaller. 



Vulva composed of two segments, whereof the proximal is smal- 

 ler , quadrate , with the middle of its distal edge cleft by the short 

 generative aperture; the distal segment, or cap, is larger, polished 

 and closely adherent to the external and distal surfaces of the proxi- 

 mal segment; its inner margin is nearly straight, its inner angle 

 produced and rounded, is distal surface oblique and slightly concave, 

 and its external surface exceedingly convex. 



Length from less than 30 to a little over 50 mm. In the drawings 

 of Dr. Karsch's specimens, the movable dactylus on both pairs of 

 forceps is represented as composed of but one segment; and the cap 

 of the vulva is made to appear as if composed of two segments. 



Mr. Butler was apparently ignorant when he described Z. barbata 

 of the existence of Dr. Karsch's paper. The specimens upon which 

 this species was established differ only in colour from the specimens 

 of Z. banksiana. Nevertheless it was not with this species that they 

 were compared but with Z. laevissima — a species with which her- 

 cules has but little affinity. 



The British Museum has specimens of this species from Sumatra 

 (Carl Bock and H. 0. Forbes) and from Padang on the W. coast of 

 the Island. In the Berlin Museum, according to Dr. Karsch, in ad- 

 dition to specimens from Sumatra there is one or more (?) stated to 

 be from Ceylon. I however doubt this locality.
