jections on the whole dorsal side. These consist, however, all of some secre- 
tion which may be removed by treating the mites with boiling lactic acid. The 
cuticle underneath is then found to be smooth but dull. On the ventral side 
it is reticulated by more or less circular depressions. 
Propodosoma highly arched, separated from the hysterosoma by a deep 
transverse furrow and sloping very steeply downwards towards the anterior 
end. Lamellz wide, of almost even width throughout, fairly thick, converging 
forwards, with short, blunt free cusps, the inner edge of which is excavated (fig. 68). 
Translamella a narrow distinct ridge, with two small semispherial projections 
carrying the rostral hairs. In front of the translamella there is a sharp dark-

coloured tooth (fig. 72). Interlamellar hairs situated close to the lamelle near 
their middle. Lamellar hairs short, curved, leaf-shaped with dentate edges, 
situated on top of the cusps. Rostral hairs probably of similar shape. 
Pseudostig mata fused with the base of the lamelle, long, tube-shaped, 
directed outwards and obliquely upwards. Pseudostigmatic organs (fig. 70) 
with very long slender peduncles, with short rather flattened heads, pyriform 
in outline and with numerous fine hairs. 
Mouthparts (fig. 73). Hypostome large, very highly arched, penta- 
gonal, with rounded angles, with reticulated texture; hypostomal hairs small, 
inserted far forwards, half as far from the anterior edge as from one another. 
Maxille short and broad with dark-coloured basal part and short male; max- 
illary hairs short and inserted one pair near the posterior margin a little nearer 
the lateral than to the median edge, the other near the anterior margin of the 
basal part.
