apices overlap the bases uf the dorsal pockets. The narrower, 

 longer dorsal pockets extend caudad for about one-half the length 

 of the ninth segment. In this instar the lateral pockets first appear. 

 They lie laterad of the dorsal pockets, are slightly curved and some- 

 what narrower and shorter than these. 



In the fourth instar the ventral pockets are longer than in the 

 preceding instar, and are now more than two-thirds the length 

 of the dorsal pockets. The ventral, still the longer of the two pairs, 

 are about the same distance from the tip of the ninth segment. 

 They are beginning to be enfolded by the lateral pockets, which 

 have broadened and are now somewhat concave on the inner sur- 

 face. The lateral pockets are longer than the ventral pockets, but 

 shorter than the dorsal. 



In the fifth instar the three pairs of pockets are rather darkly 

 chitinized. The ventral pockets are broad at the base and taper 

 gradually to narrowly rounded apices. They are the shortest of 

 the three pairs, though nearly as long as the dorsal pair. Only the 

 extreme apices of the dorsal pockets are visible, their basal portion 

 being hidden by the broader ventral pockets. They are still longer 

 than the ventral pockets, but are now exceeded in length by the 

 lateral pockets. These are somewhat spoonlike and have more com- 

 pletely enfolded the dorsal pockets.
