158 Haemaphysalts punctata 
proximal cusp: hypostome spatulate, five files of sharply pointed teeth 
on each half (we have found a slight degree of variation in this 
respect, the specimen selected for the figure, PI. XIV, Fig. 2, possessing 
an irregular sixth file on the right half of the hypostome; we have also 
seen a female of H. punctata possessing six complete rows of teeth on 
either half of the hypostome); the anterior, median and posterior teeth 
are smaller than the rest; corona well-developed, studded with minute 
denticles (the corona is frequently curled over on to the dorsal surface 
of the hypostome and may escape observation if the curling is extreme). 
Legs of moderate length, dark-brown, strong; coxae slightly longer 
than wide, each bearing a short wide spur at the posterior margin, near 
the internal angle ; tarsi relatively short, spurred, the single spur on each 
being terminal: pulvilli of medium size; two-thirds length of claws. 
(Canestrini (1890) gives the length of the legs as follows: Pair 1 = 295 
mm., II = 2‘50 mm., Ill = 2'5 mm., IV = 2 mm.) 
Gorged (PI. XIII). Body oval, more or less distended, may 
attain a size of 12 x 7'5 mm. (Canestrini, 1890); colour variable—light 
steel-grey, slate-grey, brownish or brownish-black, yellowish streaks 
and irregular markings present according to the condition of distension 
of the Malpighian tubes; dorsal and ventral surfaces punctate: marginal 
grooves and festoons obliterated; postero-median and accessory grooves 
well defined; anterior to these, four short almost parallel grooves, the 
outermost of which are often interrupted at the middle of their length 
(PI. XIII). Venter: — post-anal groove not so sharply defined as in 
unfed $ and its bifurcated anterior extremity is obliterated: two dimple¬ 
like depressions, one on either side of post-anal groove: genital orifice 
slightly anterior to level of coxae II, but position varies according to the 
state of engorgement, being pushed more and more forward until ovi- 
position commences, when it lies nearly at the base of the capitulum. 
Otherwise as in ungorged $. 
Male (Plate XIII). 
Unfed. Length (measured as in female) 2 6—327 mm., bi’eadth 
(maximum) l - 67—2’04 mm. 
Body ellipsoidal in contour, wider behind than in front, convex 
dorsally, concave ventrally: scutum covers entire dorsal surface; dark 
reddish-brown with darker, almost black irregular markings; glabrous 
and polished; punctations fine, numerous, regularly distributed; 
scapular angles narrow; cervical grooves deep anteriorly, shallow and 
divergent posteriorly; marginal grooves narrow, sharply defined,
