jection finlslies posteriorly with a sharper shoulder, 

 and is not carried so far back. There is a row of 

 very fine curved hairs round the margin, and two 

 longitudinal rows of similar hairs on the notogaster. 

 Genital and anal plates at opposite extremities of the 

 sternal plate; the former smallish and pentagonal 

 with the point forward, the latter large and almost 

 square. 



Nym;ph. 



A very active creature. 



Colour. — Abdomen and hinder part of cephalo- 

 thorax almost colourless, but with a slight grey or 

 yellowish tinge; the creature being, however, very 

 transparent, the internal organs are seen through the 

 dorsal surface, and thus colour is given, usually yellow 

 or green. Rostrum and legs pink or reddish. 



Texture highly polished. 



Cephalothorax without markings, palpi generally 

 showing. Rostral hairs more conspicuous than those 

 of the adult. Pseudo-stigmatic organs similar to those 

 of adult. 



Legs of about the same comparative length as those 

 of the adult. Tactile hairs long on all the legs ; most 

 joints have a whorl of fine curved hairs. 



Abdomen similar to that of the adult in most respects 

 except colour and texture, but the progaster is an 

 even curve, not indented ; the antero -lateral angles do 

 not project, but they each bear a hair or spine stronger 

 and longer than the others on the abdomen, and stand- 

 ing transversely outward ; all the hairs on the abdo- 

 men are more conspicuous than those on that of the 

 adult, but still small. 



Distribution. — Generally distributed, chiefly found 

 in moss ; and principally in spring and summer. The 

 species has been recorded in France, Germany, and 

 Italy.
