EREMJIUS PREVIPES!. 477 



raised except near the hind margin. The raised por- 

 tion is arched but does not sink gradually to the edge 

 of the abdomen except anteriorly, being surrounded 

 on the other sides by a broad, more horizontal, and 

 much more gently curved portion, which, however, 

 does not rise toivards the lateral margin as that of 

 E. cymha does. The progaster is narrow and convex ; 

 the hind margin has a very small median point. The 

 notogaster is reticulated ; the reticulations rather 

 regular but not hexagonal, about 110 to the millimetre ; 

 the depressions are very shallow and about five times 

 as wide as the intervening ridges, so that the abdomen 

 looks rather as if fine net were stretched over it ; but the 

 reticulations most usually have a straight side, not a 

 point directed forward. There are a few very short 

 sharply curved hairs round the hind margin, and four 

 rows of minute hairs on the notogaster, very caducent 

 and not easily seen. The sides of the dorsal plates are 

 much turned over on to the ventral surface posteriorly, 

 but with a piece scooped out in the median line below ; 

 the hinder part of the ventral plate small and almost 

 triangular, with straight sides and the point directed 

 backward. Genital and anal plates nearly square, the 

 latter rather more oblong, the former placed far for- 

 ward, the latter near the posterior end. 



Nymph. 



Colour light yellow-brown, with a somewhat darker 

 and redder shade over the legs and the hind portion 

 of the abdomen. 



Texture dull, leathery. 



Shape pyriform and tolerably regular. 



Cephalothorax. — Rostrum conical, truncated, with 

 an obtuse central point ; the ends of the palpi show 

 slightly beyond the anterior margin ; it is divided from 

 the rest of the cephalothorax by a sharp indentation. 

 The remaining portion of the cephalothorax is rounded,
