BREMiEUS CYMBA. 473 



as tbey project a little. The ventral plate is mucli 

 smaller than the dorsal, which is reflexed, and embraces 

 the ventral plate, particularly posteriorly. The whole 

 ventral surface is reticulated like the dorsal. The 

 genital and anal plates are very large, and close 

 together ; the former almost square, the latter oblong. 

 The apodemata do not reach the sternum. There is a 

 lateral tooth-like projection of the ventral plate between 

 the second and third pairs of legs. 



Nymjph. 



Colour light, but dull, yellowish-brown or buff, 

 shaded with a dull greenish tinge. Legs and rostrum 

 redder. 



Texture leathery, without the slightest polish. 



Cephalothorax not very unlike that of the adult, 

 but still with considerable differences from it. The 

 rostrum is less wide, and much less rounded ; it is 

 slightly truncated ; the gense being more distinctly 

 separated from the frons than in the adult. In living 

 specimens a more pointed effect, as in the figure, 

 frequently arises from, the position in which the rostrum 

 is held, and the slight protrusion of the points of 

 the mandibles (unfortunately in engraving and print- 

 ing my lines showing how this effect arises have 

 become obliterated). The remainder of the cephalo- 

 thorax has really much the same ridges, &c., as in the 

 adult, bub the transverse ridge is not so straight, and 

 curves more into and forms a line with the lateral 

 ridges, and the whole is less hard and sharp, and 

 more apt to run into minor wrinkles and granula- 

 tions, particularly at the side, than the harder cuticle 

 of the imago. The rostral, lamellar, and interlamellar 

 hairs are short and have tiny peduncles, and little, more 

 or less globular heads (as to which see below when 

 those on the abdomen are mentioned). The lamellar 

 and interlamellar hairs are rather larger than those of
