Habitat in Java.

I bave applied the specific name of Tricoidi/loides to designate this insect, 

 which not only in its general form and nodose thorax, but also in its peculiar 

 colours (by which alone it is distinguished from nearly every other Orthopte- 

 rous insect), so singularly represents the Cicindelideous genus Tricondylu. 

 Another curious circumstance attendant upon this analogy is, that the locality 

 of both these groups is the same, namely, Java.
