160 Haemaphysalis punctata 
to those of $ : foveae extremely small. Venter resembles that of female, 
the genital orifice being represented by a small imperforate pit: spiracles 
almost circular; macula excentric, situated towards the inner margin of 
the spiracle. 
Capitulum—length (from tips of palps to postero-dorsal ridge) 
0'23—0'29 mm.: basis capituli widest at base of palps; dorsal surface 
extended laterally on either side as a triangular process with rounded 
point; porose areas absent: palps longer than hypostome, of elongated 
triangular form; prominent external angle on article 2, which bears on 
its infra-internal margin a fringe of about 5 feather-like hairs; article 3 
carries a single feather-like hair in a corresponding position : chelicerae 
—digit as in female: hypostome slightly spatulate; two hies of teeth on 
each half. 
Legs paler in colour than in adult; no tarsal spurs; otherwise as in 
adult. 
Gorged. The changes undergone by the nymph during engorgement 
are similar to those of the $, viz. obliteration of the grooves on the 
surface of the body, alterations in colour, etc. When replete the nymph 
measures 33 x 2 mm. 
Larva (Plate XII). 
Unfed. Length (tips of palps to posterior margin) 0'58—(>70 mm., 
breadth (maximum) 0'43—048 mm. 
Body oval, wider posteriorly, less battened than other stages; colour 
dull ochre-yellow ; few pale-coloured hairs, regularly arranged (see Figs. 
1 and 2); scutum broader than long (length, 025 mm., breadth, 0 32 mm.); 
reddish-brown in colour, contour follows that of body in anterior half, 
postero-lateral margins almost straight, with large rounded postero¬ 
median angle; surface reticulated as in nymph; cervical grooves deep, 
straight and not extending to posterior margin: foveae absent; postero¬ 
median and accessory grooves faintly marked. Venter: — post-anal groove 
slight; genital grooves absent: spiracles absent. 
Capitulum, length (tips of palps to dorsal ridge) 015 mm.: basis 
capituli as in nymph but lateral angles less pronounced : palps tri¬ 
angular, external angle not prominent; all articles fused together with 
the exception of the 4th, which is relatively larger and more terminal in 
position than in the other stages; a siugle feather-like hair is carried on 
the infra-internal margin : digits of chelicerae as in nymph and female: 
hypostome with four files of teeth, two on each half.
