426 BRITISH OEIBATID^. 



short, spike-like processes on the progaster. Nicolet 

 describes a small, depressed, oval mark on the anterior 

 part of the notogaster which I have not detected in 

 English specimens. Genital and anal plates square, 

 close together. 



Larva. 



Colour of the young larva semi-opaque, yellowish- 

 white, with one or two vague orange or yellowish spots 

 caused by portions of the alimentary canal showing 

 through the skin. The legs and rostrum light red ; 

 all the numerous long hairs are jet black. At this 

 stage the larva is quite clean and is a beautiful 

 creature. 



Shape. — As seen from the dorsal aspect the form 

 has a tendency to be irregularly pentagonal, the cepha- 

 lothorax being triangular and somewhat pointed, the 

 abdomen somewhat square; by far the best idea is 

 obtained, however, by a side view ; it is then seen that 

 in consequence of the long tarsi, which are carried 

 much raised at the proximal end, the body of the crea- 

 ture is kept well above the ground. 



Cephalothorax. — Eostrum sharp ; it points perpen- 

 dicularly downward ; its posterior edge is overhung 

 by a fold of the soft skin of the cephalothorax ; the 

 almost colourless palpi show very plainly at the side ; 

 the cephalothorax rises sharply to the level of the 

 abdomen and has the pseudo-stigmata set in papilla- 

 like projections which bear a dark orange-brown ring 

 round the opening. The pseudo-stigmatic organs long, 

 really setiform, but usually, from extraneous matter 

 adhering to them, having the appearance of being 

 gradually thickened towards the end; they make a 

 double curve forward and outward, and are rough and 

 black. Interlamellar hairs close to the pseudo-stig- 

 matic organs and very similar to them ; there is also a 

 short hair outside each pseudo-stigma. 



Legs very long, about twice the length of the body ;
