364 Mr. TTuc^li Scott on certain Nydcrihiidse, 



situated dorsally and ])o.stciioily (Fig. G) : one pair, only 

 separated from one another by a distance = 1 to 2 diameters 

 of the spiracle, quite close to the posterior extremity of 

 the body ; the other pair, separated from one another by 

 a considerable distance, and about ] 'the lenc>-th of the 

 body from its hind end. The ventral surface of the larva 

 shows the peculiar configuration mentioned by Spciser 

 (o2>. cit., p. 27). There is a median area sunk slightly 

 below the level of the surrounding body-surface, with its 

 cuticle much wrinkled and creased longitudinally, the 

 creases continuing in front along the ventral surface of 

 the constricted part of the larva's botly. The cuticle of 

 the surrounding body-surface, where it edges on and 

 slightly overhangs the median area, has a different appear- 

 ance, being marked with fine creases radiating from the 

 edore of that area.
