Many years ago I recognized an insect obtained by my native collector 

 at Johore in the Malay peninsula, as the Mantis thoracica of De Haan, a 

 species briefly described in Latin from a specimen without locality, and in 

 1878 I published a short account of it referring it to the genus Euchomena, 

 I have since received from Mr. H. O. Forbes, who obtained the insects at 

 Bantam in the island of Java, two spirit-specimens of the male of De 

 Haan's Mantis heteroptera, which, on comparison with the female insect 

 above-mentioned, prove to be examples of the opposite sex. The insect 

 from Celebes considered by De Haan to be the female of his Mantis 

 heteroptera consequently represents, as indeed its totally different structure 

 shows, a totally distinct species, for which the name heteroptera may con- 

 veniently be retained. 



The following are the measurements of one of Mr. Forbes' specimens 

 of the male : — 



Total length of body 62-5 millims. ; height of head 3, breadth of head 

 6 ; length of pronotum 28, of which the anterior lobe is 5, breadth of 

 pronotum at narrowest part just behind dilatation 1-5 ; length of tegmina 

 35, width of tegmina across middle G, width of marginal licld 13 ; length
