apterous, and some of the division Emesaria resemble the so-called 

 " walking-stick" insects of the orthopterous family Phasmidse. 



The Emesinge are almost universally distributed and are very 

 predaceous insects. Their anterior legs are particularly developed 

 and adapted for capturing and holding their prey, the greatly 

 elongated coxae giving them no inconsidei'able resemblance to small 

 or undeveloped species of Mantidae. 8ome species of the Stenohrm- 

 aria also somewhat resemble members of the Tipulidae (Diptera). 



In the genus Pkearia, found in this fauna, one species, P. domes- 

 tica. Scop. (=-mar(/inatus, Hein.), has been described by Heineken 

 as being so predaceous, that a female killed and sucked a companion 

 of her own sex, her own mate, and, after only a few days' fast, her 

 own young, and sucked her own eggs I

Anterior femora spined beneath for their whole length, a little 

 or considerably longer than the tibiae; anterior tarsi short, not 

 longer or a little longer than the posterior tarsi ; hemelytra 

 present or absent, when present, so far as known, ornamented

Four genera found in British India are now included in this 

 division.
