NOTASPIS LUCORUM. 373 



sligbtly sinuated anterior margin, bordered by a raised 

 line, except in the middle, where the abdomen almost 

 coalesces with the cephalothorax ; and having a rounded 

 point posteriorly; it is much arched, and is entirely 

 covered with rather large and clear punctures. A 

 strong^ straight spine projects from the edge of the 

 abdomen, between the second and third legs, and there 

 are four longitudinal rows of long, fine, curved hairs 

 on the notogaster, and an extra pair near the posterior 

 margin. Genital and anal plates nearly square (the 

 latter the larger), at opposite ends of the abdomen. 



This species is extremely like JSf. jpilosa, so much so 

 that I had at one time grave doubts whether the two 

 species were really distinct ; I think, however, that the 

 smaller size, less pointed shape, and much redder colour 

 of N. Jpilosa, the much greater length of the hairs on 

 the notogaster in that species, and more especially the 

 much greater length, and more gradually pyriform 

 shape, of the pseudo-stigmatic organs in N. pilosa, 

 constitute a sufficient distinction ; moreover N. pilosa 

 is rare and is not usually found with N. Incorum, 



N. lucorum is an extremely variable species, both in 

 shape and size ; the abdomen is much longer in propor- 

 tion, and more pointed in some specimens than in 

 others ; the breadth also varies considerably. The 

 whole creature is, however, always larger and more 

 pointed than N. pilosa. 



Nymph. 



This is a very beautiful creature. 



Colour of rostrum and legs light rosy-brown, of hind 

 part of cephalothorax and abdomen semi-transparent 

 white; the internal organs partly show through the 

 integument, the ventriculus and expulsory glands red- 

 brown to crimson, the rest of the alimentary canal and 

 its cecse yellow or green, the preventricular glands 

 nearly black ; these colours vary considerably, but 

 usually give a diversified and pleasing appearance.
