irregular, flattened lumps, with depressed spaces between the 

 pairs; the two lumps of each pair almost touch on their inner 

 edc^es ; these lumps bear two longitudinal rows of short spatulate 

 hairs of the same colour as the abdomen. All the lines of the 

 abdomen and indeed of the whole creature are wavy and irregular, 

 chiefly from the roughness of the surface. 



Found in moss. 



In my former paper I have mentioned the possibility of 

 Thorell's species being a nymph of H. piceus; his description 

 would agree with that nymph nearly as well as with this species, 

 but I think this is his creature.

 Average length about • 7 mm. 



This species may be known by the abdomen being pointed 

 posteriorly instead of round, and the stigmatic hairs being long 

 and filiform, very slightly thickened at the ends, the interstigmatic 

 long and setiform, abdomen polished but marked with very fine 

 dark wavy lines. 



A few specimens found at Epping Forest.

This nymph is figured and described by Koch as a separate 

 species under the name of Murcia rubra, fasc. 31, pi. 20. 



General efiFect of colour orange red, varying to dark pink ; this, 

 however, is produced, not by the integument, which is colourless, 

 transparent and shiny, but by minute specks of the colour thickly 

 scattered through the internal tissues underlying the skin. The 

 creature is diamond-shaped, the anterior portion of the diamond 

 being the longest. Cephalothorax not above one-fifth of the length 

 of the whole body, and with a constriction immediately in front of 

 the stigmata; anterior to this the cephalothorax is small and 

 narrow. Stigmata far apart, small and red, with short stigmatic 

 hairs, having small, almost globular clubs, a pair of fine hairs on 

 the rostrum pointing forward, and a similar pair, but stronger, a 

 little in front of the middle of the cephalothorax. Interstigmatic 

 hairs long and curving upwards and outward. Legs thin and 

 short ; no enlarged joints ; the penultimate joints of front pair 

 bearing long hairs. Tarsi clothed with hairs, and a few others 

 scattered on the legs. Abdomen flat in young specimens, becoming
