Explanation of Plate 1 
Fig. 1. Larval integumentary sense organ of Haemaphysalis punctata Can. 
and Fanz., redrawn from K. W. Neumann (1942). A, in direct 
view; B, in side view: aR, sensory duct; Bbl, internal vesicle; Bz, 
generative cell; C, cuticula; Dz, gland cell; Hyp, hypodermis; L, 
lips; Oe, mouth of the sensory duct; R, frame; Rm, fringe; V, 
protrusions of the frame; Z, tooth. 
Fig. 2. Schematic drawing of a sensillum sagittiforme of Eyalomma, after 
P. Schulze: Astr, axial fiber; Dp, projecting ledges; Dr, gland cell; 
Ek, terminal chamber; KEst, knot of the scolopale; NK, enveloping 
cell nucleus; Sch, tuft; Schk, tuft chamber; Sg, sensory cell group 
outside the duct. The chitinous structure surrounding the sense 
organ has been omitted. 
Fig. 3. Schematic drawing of a sensillum auriforme on the alloscutum of a 
female Eyalomma, after P. Schulze: Astr, axial fiber; Dz, shaded 
zone of the disk; Gh, papilla with terminal apparatus in central 
area of the disk ; Hz, unshaded zone ; Nk, enveloping cell nucleus ; 
Pa, pigmented and thickened section of the duct; Sk, sensory cell 
nucleus; Tf, supporting plicature. The chitinous structure sur- 
rounding the sensory organ and gland cells has been omitted. The 
disk covering the sensory cell and the terminal apparatus is assumed 
to be transparent.
