, The late Prof. Riley estimated the total number of existing species of insects at ten 

 millions (about 300,000 are known at present) ; and when it is considered that less than 

 a dozen species of such large insects as PhaHmidce are known from a locality so frequently 

 visited as Madagascar, and that our British species of parasitic Mymenoptera, among 

 which are the smallest insects known, are numl)ered l)y hundreds, although very 

 few entomologists have worked at them at all, Prof. Riley's estimate cannot be regarded 

 as excessive. Excepting the larger butterflies and beetles of the best-explored countries, 

 our knowledge of the insects of the world is far more incomplete than many persons, 

 even though experienced entomologists, might be inclined to suppose. 



At present the Eritish Museum Collection of Phasniidce fills 120 cabinet-drawers, 

 but will soon require to be extended. More materials, at all events, are needed before 

 a satisfactory revision of the classification of Fhasmidce can be attempted.

This genus differs from most of the Lonchodmcp in having winged males. 



Some particulars respecting the supposed females of this insect are given in the intro- 

 ductory portion of this paper. The colour, when alive, was evidently green, and the 

 legs are strongly carinated and spined, nearly as in the male ; but the body is otherwise 

 unarmed. The typical male is from Malabar. The dimensions of the large female from 

 Borneo are given below ; it will be seen that they are somewhat asymmetrical.
