HEM IP TERA. 127 



G. Wing-covers when well developed with a cuneus (Fig. 

 143); those forms in which the adult has rudimentary 

 wing-covers have no ocelli, p. 140. . . . ACANTHUDjE. 



GG. Wing-covers when well developed without a cuneus ; 

 those forms in which the adult has rudimentary wing- 

 covers have ocelli. 

 H. Ocelli wanting. 



I. Body linear. p. 136 EMESID/E. 



II. Body greatly flattened, p. 139 ARADID/E. 



III. Body of ordinary form. p. 137. REDUVIID/E. 

 HH. Ocelli present, though sometimes difficult to see. 



I. Beak very long, reaching to or beyond the inter- 

 mediate coxae, p. 134 SALDID^E. 



II. Beak not reaching the intermediate coxae. 



}. Front legs with greatly thickened femora. 



p. 138 PHYMATID^:. 



JJ. Front femora somewhat thickened, but much 

 less than half as wide as long. p. 137. 



REDUVIID.'E. 

 FF. Beak four-jointed. 



G. Front legs fitted for grasping prey, the tibiae being 

 armed with spines and capable of being closed tightly 

 upon the femora, which are stout. In the forms with 

 long wings the membrane is usually furnished with 

 four long veins, bounding three discal cells which are 

 often open. From these cells diverge veins which 

 form several marginal cells. (Fig. 142). p. 138. 



NABID^E. 

 GG. Front legs fitted for walking. 



H. Wing-covers with cuneus. Membrane with one 

 or two closed cells at its base, otherwise without 



veins. (Fig. 144.) p. 140 CAPSID^E. 



HH. Wing-covers without cuneus. Membrane with 

 four or five simple or anastomosing veins arising 

 from the base ; or with a large number of veins aris- 

 ing from a cross-vein at the base. 



I. Ocelli wanting ; membrane with two large cells 

 at the base, and from these arise about eight 

 branching veins. (Fig. 145.) p. 140. 



PYRRHOCORID^E. 



II. Ocelli usually present.
