dorsal surface ; palpi short and thick ; article 11 curved toward the 
ventral surface, twice as long as article 111 ; hypostome with numerous 
denticles at tip ; followed by seven or eight rows of strong teeth, three to 
a row ; below this numerous squamiform teeth ; from middle of hypo- 
stome downward a fourth row of small teeth along median line ; inner 
apophysis of mandible transverse, unidentate {XI 1, m) ; onter apophysis 
bidentate. Legs strong, chestnut brown, ringed with lighter colour at 
distal extremities of articles ; marked with punctuations ; coxae I with 
two short, flat spines, a single spine similar to these, hut stronger, on 
coxae IV {XII, n) ; tarsi short, thick, suddenly attenuated. 
Female. — Unengorged, female a little larger than male ; when engorged,, 
body oval," 'fiat-, reaches dimensions of 33 him. long by 20 mm. wide. 
Shield (A 111, d) triangular, scarcely wider (4 mm.) than long ; posterior 
lateral sides almost straight ; posterior angle narrow ; scapular angles 
prominent in anterior points ; eyes in anterior third of length ; cervical 
grooves deep and wide, prolonged almost to the posterior margin ; 
punctuations unequal ; large ones rare ; fine ones numerous, marked on 
light areas by black spots ; r ground colour bronzy grey as in male, and 
with spots of brown along the anterior margins, on the cervical grooves 
around the eyes, on the posterior margin opposite the cervical grooves, 
and near the posterior third of the lateral areas ; eyes flat, whitish, 
brown when in preservative fluid. Dorsal surface {XIII, d) 
deep red-brown, wrinkled and deeply punctuated ; a marginal 
groove ; eleven posterior festoons well marked, dorsal porose 
areas present. Ventral surface reddish brown; posterior festoons 
very apparent. When engorged, body becomes light brownish 
grey, with a few salmon coloured blotches, surface usually 
covered with a whitish bloom ; dorsal and ventral surface with grooves 
as in hebraeum ; stigmatic • plates large, whitish, triangular, with angles 
rounded ; posterior lateral angle prolonged laterally, but not so much as 
in male. Rostrum 2.5 mm. long, reddish brown y porose areas of medium 
size, almost circular; hypostome spatulate, numerous denticles at tips, 
eleven rows of teeth on each half, three teeth to a row ; 
squamose denticles to base ; inner apophysis of mandibles with 
process transverse, tridentate {XIII, e) ; outer apophysis tridentate ; 
palpi curved toward the ventral surface from the base of 
article II, wide, with parallel edges, otherwise similar to those 
of male. Legs long, strong, chestnut brown, ringed with lighter at distal 
ends of segments. Coxae I with two short teeth, strong, flat, separated ; a 
triangular prominence flat, on the posterior margin of the others, larger on 
coxae IV ; tarsi II, III, and IV sharply attenuated near their extremity. 
Nymph (engorged).— Body widely elliptical, broadly rounded on 
both ends, with sides nearly parallel ; up to 9 mm. long b}^ 6 mm. wide ; 
colour dark bluish, changing to a bright brown toward moulting time, and 
often covered with a coarse brown bloom. Dorsal shield {XII T, h) a little 
wider than long, broadly rounded on posterior angle, posterior lateral 
edges nearly straight ; colour uniform dark brown, cervical grooves deep, 
then broad and shallow, extending nearly to posterior edges ; punctuations- 
unequal, large ones very large ; eyes at lateral angles light coloured. 
Dorsal surface smooth, four anterior furrows ; outer ones broken in 
middle ; three posterior furrows, reaching nearly to the posterior margin, 
where there are two short furrows between their extremities. Ventral 
surface with furrows as in female ; stigmatic plates whitish with dark
