V . — Some Remarks on the Mantis Tribe of Insects . By the late Dr. J. 
Adam. 
The varieties of the insect tribes, met with in India, may be said to be innu- 
merable; and hence opportunities are afforded for the study ef entomology, that 
do not occur in more temperate regions of the globe. The singularity of their 
appearance, and the striking changes, which many of them undergo, by offering a 
wider range of enquiry, as respects the economy of the insect itself, or its relation 
to other animals, combine moreover to confer a greater interest on the science, 
find allure those to it.s pursuit, who might otherwise, consider such researches as 
frivolous and unworthy of their notice. Among the most remarkable insects for 
their external form, in India, may he reckoned the various individuals of the 
Mantis tribe, of which the accompanying are examples ; namely the M. gongyludes 
and AI. siccifolia . According to the latest classification, this tribe has been divid- 
ed into the two families of the Mantula and Phasmida , founded on a difference in the 
structure of the fore foot or leg; this member in the former, being raptorious , or 
provided with a sharp claw, and a hollow on the leg and thigh, and a double series ot
