MR. A. D. MICHAEL ON UNRECORDED 



across the ventral plate anterior to the genital opening ; which is large, 

 nearly square, and placed between the coxse o£ the fourth pair of legs. The 

 genital plates bear double rows of small fine hairs on their inner edges. Anal 

 opening almost touching the genital and also almost reaching the posterior 

 margin ; much longer than broad, the sides curved. 



Habitat. A single specimen from moss on the Ruahine Range, New Zealand 

 (J. W. Baker's collection).

Colour yellow-brown of medium depth. 



Texture dull ; slightly, but not conspicuously, rough ; chitin thin and 

 slightly translucent. 



Cephalothorax about one-third of the length of the abdomen. Rostrum 

 truncated at the tip, but rather narrow. Rostral hairs short and small, but 

 rather thick ; inserted nearly at the antero-lateral angle of the rostrum. A 

 large, chitinous, cylindrical apophysis, nearly, but not quite, half as long as 

 the cephalothorax, springs from the edge just behind the rostrum ; it is 

 thickest where it springs, and bears a long hair at its distal end ; this hair is 

 thick where it arises, but gradually diminishes ; it curves strongly inward, 

 the hairs from the two sides of the body cross. The two apophyses are joined 

 by a thickened ridge. The cephalothorax is deeply indented at the side for 

 the insertion of the first and second legs, which come almost to the dorsal 

 surface. The insertions, especially of the first leg, are protected by curved 

 knife-like ridges arising from the body and overlapping the coxaj. The 

 pseudo-stigmata are circular openings on the dorsal surface surrounded by a 

 slight rough ridge. Pseudo-stigmatic organs small and globular, entirelr/ 

 sunk inside the pseudo-stigmata, so that no peduncle is seen. The two pseudo- 

 stigmata are joined posteriorly by a slight, irregular, rough, curved ridge. 



Legs flattened, longish ; the fourth pair pass the hind margin by about two- 

 thirds of the length of the tarsi ; the femora and tarsi are the two longest 

 joints ; the genuals and tibiae of about equal length ; the tarsus is as long as, or 

 longer than, the genual and tibia together. All the legs are bordered on the 



* Cuphinarius, a basket maker (from the form of the interlacing spines near the 

 posterior end) .
