NOTERUS SYLVESTRIS. 493 



six times as wide as the ridges. There is a small 

 rounded projection below the hind margin. There 

 are four longitudinal rows of about five thick, curved, 

 rather spatulate, slightly imbricated, white hairs on 

 the notogaster (two being on the central part and one 

 on each raised margin), one longer similar hair on each 

 postero-lateral angle; two pairs of shorter similar 

 hairs on the hind margin, and one pair on the lateral 

 margin, a little in front of the posterior angle ; there 

 is also a short hair inside the an tero -lateral angle. 

 Notogastral plate greatly suflBexed on to the ventral 

 surface. Ventral plate merely a narrow band. Genital 

 and anal plates near together but not touching, the 

 former shortish and almost round, the latter long and 

 narrow ; there is a triangular chitinous piece between 

 the two. 



Nympli. 



Colour of cephalothorax and legs red-brown, of 

 abdomen yellowish-white. 



Texture of cephalothorax reticulated as in the adult, 

 of the abdomen dull, thickly set with raised dots, which 

 give it the appearance of shagreen. 



Cephalothorax very like that of the adult [the ros- 

 tral and interlamellar hairs are omitted in the plate] . 



Legs very similar to those of the adult, but a little 

 shorter in proportion ; the tubular projections of the 

 sternal plate, into which the third and fourth coxsb of 

 the adult are inserted, are not present in the nymph. 



Abdomen nearly oblong, but the margin slightly 

 sinuated. Progaster nearly straight, with the angles 

 very slightly rounded ; wider than the cephalothorax, 

 and raised much above it. A broad lateral margin on 

 each side of the abdomen is considerably raised, and 

 slopes down to a furrow, from whence the central part 

 of the notogaster rises in a slight arch. The postero- 

 lateral angles of the abdomen are quite sharp or 

 slightly projecting ; each bears a thick, curved, blunt
