 four or five terminal joints distinctly foliaceous.

In the structure of the head this remarkable form differs from the 

 similar and allied Fyrgomantis of Africa in having the juxtocular lobes 

 prolonged into two tall cones which touch one another in the middle line 

 instead of the middle of the vertex together with the juxtocular lobes 

 elevated into a median azygous process. 



The part of my description {loc. sujpra cit.) relating to the prothorax 

 should read thus: — " Frotliorax narrow, with its sides suparallel, slightly 

 narrowed behind the insertion of the fore legs, then widening again slightly 

 to its base ; its supracoxal dilatation and cervical groove hardly perceptible ; 

 its neck quadrate; its disk," &c., &c. 



The structural differences between the Asiatic ScJiizocephala hicornis 

 and the African JEpiscopios (olim Schizocephala) chalyheus are of similar 

 kind and of equal importance ; in the former the " ocular spines" are in 

 reality prolongations of the juxtocular lobes of the vertex, while in the 

 latter the faceted cornea of the eyes is itself produced upwards into a 

 conspicuous spine. 



Hab, Tinpahar, on the eastern flank of the Rajmahal Hills ; Ceylon 

 (Stal) ; and Kulu, Kangra, in the N.-W. Himalayas. 



The names proposed by me for this remarkable form have priority over 

 those of Stal by several months.
