HEMIPTERA. 1 95 



I find no observations regarding the food of these insects; but they 

 arc probably herbivorous. 



Only a single species has been found in the United States. This 

 is Limtwbatcs lincata. It is a small insect less than 12.5 mm. (0.5 in.) 

 in length. The legs and antennae are extremely slender, being hair- 

 like in form. Fig. 165 represents this species greatly enlarged. 



Family XXL EMESID.i:.* 



The Etm-sida includes a small number of insects in which the 

 body is very slender, and the middle and hind legs are thread-like. 

 The front legs are less thread-like, and fitted for grasping. They 

 suggest by their form the front legs of the Mantidae; the coxa is 

 very greatly elongated, more than four times as long as thick; the 

 femur spined ; and the tibia shut back upon the femur. 



This family is very closely allied to the one following. In 

 fact, by some authors the two are united. They agree in ha 

 the rostrum short, attached to the tip of the head, and with the 

 distal end when not in use resting upon the prosternum, which is 

 grooved to receive it. The great length of the fore coxa easily dis- 

 tinguishes this family from any of our species of the Reduviidae, 

 and in the Fmesida? there arc no ocelli. Only seven species of this 

 family are catalogued from the United Stat 



Our most familiar representative is /:;// \v</ Umgipts. This i:

the walking-sticks. But the raptorial fore legs, the wings, and the 

 rostrum, really give this species a very different appearance from
