HEMIPTERA .

G. Wing-covcrs when well developed with an embolium 
(Fig. 143); those forms in which the adult has rudimen¬ 
tary wing-covers have no ocelli, p. 140... AcanthiiDjE. 
GG. Wing-covers when well developed without an em¬ 
bolium ; 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. AradidjE. 
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. SaldidjE. 
II. Beak not reaching the intermediate coxae. 
J. Front legs with greatly thickened femora. 
p. 138.PHYMATIDiE. 
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. 
NABIDiE. 
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. 
PYRRHOCORIDjE. 
II. Ocelli usually present.
