beautifully simulate blossoms of different colours. And it has 

 been stated by Dr. Wallace, on the authority of a communication 

 made to him by Sir Charles Dilke, that a small Mantis found in 

 Java exactly resembles a pink Orchis-flower, and this species 



" was not only said to 

 attract Insects, but even 

 the kind of Insects (but- 

 terflies) which it allures 

 and devours was men- 

 tioned." We do not know 

 of what species or genus 

 this Insect may be, but 

 Hymenopus bicornis is a 

 peculiar form of the tribe 

 Harpagides, and has, to- 

 gether with its younger 

 state, been figured long 

 ago by Caspar Stoll in 

 his quaint and interest- 

 ing old book. 1 Though 

 it has very peculiar foli- 

 aceous expansions on the 

 two hinder pairs of legs, 

 these dilatations are very 

 different from those seen 

 in the curious Gongylus 

 gongyloides, the female 

 of which we figure (Fig. 

 146). This latter, accord- 

 ing to the information 

 we shall quote, is also a 

 " floral simulator." Specimens of G. gongyloides were shown to 

 the members of the Asiatic Society of Bengal in 1877 by Dr. J. 

 Anderson,^ who at the same gave some information about them 

 which we shall reproduce in full, because, incomplete as it is, it 

 is apparently almost the sole piece of definite information we 

 possess as to this curious Insect, or any of its congeners : 



" These Insects all came from the same locality, having been
