divergent; spiracles almost circular (270-290/r). Legs: coxa I with a 
small wide triangular spur, coxae II and III with an oblique salient 
ridge; coxae IV with a wide triangular spur, larger than that on coxa I. 
Tarsi tapering gradually, unarmed; tarsus IV more than three times 
as long as broad. 
Origin: Gonubie Park, East London, South Africa. Described 
from 4 $’s found on oxen allowed to run on “starvation camp” from 
which stock had been excluded for two years. 
Amblyomma variegatum var. n. nocens. 
Fig. 2, a-f. 
Male: body {1. 4’6-5'5 mm., w. 3‘6-4’2 mm.) closely resembles that 
of the type. Scutum: ornamentation^ differs slightly from that of 
A. variegatum', the pale areas anterior to the falciform stripe are 
golden-yellow in colour; those posterior to the falciform stripe, together 
with the lateral pale areas, coppery-i’ed narrowly margined 'with green ; 
falciform stripe isolated; cervical stripes may or may not extend back¬ 
wards to fuse with the falciform stripe; lateral spots conjoined, forming 
an arch, or indistinguishably fused with the dark-coloured marginal 
band, the lateral pale areas in such a case being absent; postero-median 
stripe narrow, with a slightly knobbed extremity; accessory stripes 
narrower than those of the type, directed towards the postero-lateral 
angles of the falciform stripe; margins and festoons entirely dark- 
coloured. The dark markings are more elevated above the general 
surface than is the case in the type. Cervical grooves deep. Puncta- 
tions numerous, much coarser than in the type, confluent in places. 
Eyes hemispherical, pale or dark, orbited. Gapitulum typical. Palps 
slender, contracted at base of article 2; article 1 carinate on ventral 
surface. Hypostome long, dentition 3 j 3 on greater portion, 4 | 4 on 
proximal portion. Ve7iter typical, spiracle short comma-shaped. Legs 
typical; coxae I with two stout spur.s, the internal blunt, the longer 
external spur more pointed ; coxae II and III with a salient ridge, three- 
fourths the width of the coxa; coxae IV with a single stout spur.
