Ahdomen with a large rounded projection in front, extending over 

 the cephalothorax and confluent with it ; thence making two strong, 

 rounded shoulders, and then tapering with a rather more gradual 

 curve to the posterior end, where it terminates in two strong, 

 conical papillae of a dark brown colour, each bearing a hair nearly 

 as long as the creature. 



Tarsi of first pair of legs, each bearing two long hairs arising 

 from a papilla and a good many shorter ones : most of the other 

 joints bear two or three shorter hairs. This is one of the best 

 species in which to observe the pulsation during the latter part of 

 the inert stage alluded to above. 



Found in moss near the roots. 



NOTASPIS LUCORUM. Koch. 



Nymph. 



General shape oval ; the rostrum forming the smaller end, the 

 widest part being about one-third of the length from the posterior 

 extremity ; two deepish indentations in the anterior portion of the 

 lateral margin, one behind the rostrum, and the other at the 

 junction of the cephalothorax and abdomen, are formed by depressed 

 lines in these places. The line dividing the cephalothorax and 

 abdomen is not a sharp one, but only a vague depression. The 

 rostrum and cephalothorax are very small, and they and the legs 

 are chitinous brown, not dark. The abdomen is yellowish white 

 and pohshed, but with a few irregular depressions and with scat- 

 tered dots and vermiform lines. About central in this portion of 

 the body is an irregularly oblong, dark, red-brown mark, pro- 

 longed anteriorly, so as to form two lighter horns, each ending in a 

 black spot, and also prolonged posteriorly by two wider projections 

 of vague and varying form ; the whole of this marking (which 

 forms a conspicuous feature) is caused by the liver and other 

 internal organs showing through, in consequence of the trans- 

 parency of the creature. 



The stigmata are small and point sideways ; the stigmatic hairs 

 very short, and bearing a blunt, pear-shaped club, which often looks 

 almost globular. There are a pair of hairs near the point of the 

 rostrum curving forwards, a longer pair on the vertex standing 

 nearly upright ; a long hair at the angle formed by the juncture 

 of cephalothorax and abdomen ; two longitudinal rows of hairs on 

 the abdomen, and a row round the same part a little within the 

 margin ; in this row the posterior ones are the largest and nearest 

 to the margin. All these hairs are whitish, but usually look 

 nearly black in consequence of the whiteness of the creature and 

 their being in shadow on one side. 



The legs are rather short; the fourth pair, which are the 

 longest, being considerably less than half the length of the body.
