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. Lamellse 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 lamellae near 

 their middle. Lamellar hairs short, curved, leaf-shaped with dentate edges, 

 situated on top of the cusps. Rostral hairs probably of similar shape. 



Pseudostigrrfata fused with the base of the lamellae, 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. 

 Maxillae short and broad with dark-coloured basal part and short malae; 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.
