Thoracic appendages: legs—The usual three pairs of legs 
are long and of considerable strength consisting of the coxa, 
trochanter, femur, tibia and tarsus. The animal can walk very 
swiftly on its tarsal joints on ground and even on a smooth 
surface like glass 
The bases of the coxae of the two sides (COX.) are closely 
approximated, between which lies the rostrum (Fig. 2). Tro- 
chantin (TROCH.) is a more or less triangular sclerite situated 
at the base of the coxa. Trochanter (TRO. ) isa short and rather 
slender joint articulated to the femur by a ginglymous joint. 
Femur is the strongest att of the leg having near its 
distal end (in the first leg) 6 spines arranged in two rows of 
three each. 
Tibia (TB.) is longer than the femur and is connected to 
the latter by a ginglymous joint which is raised up especially 
in the third. leg. The distal half of the tibia is ornamented 
with thick, ee bristles, besides a few strong spines ealled 
calcaria sig Ly. 
Tarsus (TR.) is short and slender, consisting of three 
joints, the basal being the longest. All the three tarsal seg- 
ments are black and have closely set small spines. The tarsus 
ends in a pair of black claws which are supported beneath by 
stalked pads known as pulvillus. West (Transactions Linn. 
Soc. London, XXIII, 1851) regarded the pulvillus as homolo- 
gous to an additional tarsal segment, the claws in that case 
being regarded as modified setae. According to other authors 
the stalked pads are modified glandular setae swollen at the 
ends. 
The fore wings, known as hemelytra (fig. 5a), 
are attached to the lateral margins of the mesoscutum by smal! 
chitinous plates the auxiliaries or ossicula (Audouin). Each 
forewing is 7°38 mm. long and 3-7 mm. broad being partly 
coriaceous and partly membranous. The coriaceous part is 
ochreous in colour, with a black discal spot, and is marked 
off by means of two longitudinal sutures (suture clavi and 
median suture) into three areas, the clavus, corium and 
embolium. The clavus lies between the inner margin of the 
wing and the suture clavis, and next to the mesoscutellum 
when the wings are in repose. The corium (CR.) lies next to 
the clavus, between the two sutures. The embolium or costal 
area (EMB.) lies next, ending distally in the costal margin of 
the wing. This is the longest of the three areas. The cuncus 
(Comstock p. 125, Fig. 141) is absent. The membranous region 
is dark brown in colour. en the wings are in repose the 
membrane of one side crosses over to the other, the right cover- 
ing the left. 
The following chief veins can be recognized in the fore-
