As lias already been observed, Schmidt has shown that in the male 

 of the Coccidse, there is a true hypermetamorphosis, as shown by 

 Fig. 637. In Aspidiotus nerii there are five stages, there being two

larval (i, 2) and two pupal stages (3, 4, 7). Stage 3 (Fig. 637, 2) may 

 be compared with the propupa stage of Riley (Fig. 581). 



We have already, on page 602, described the hypermetamorphosis 

 of the neuropterous insect Mantispa (Fig. 638). 



In Meloe the freshly hatched 

 larva, or " triungulin " (Fig. 639, a), 

 is an active Campodea-like larva, 

 which runs about and climbs up 

 flowers, from which it creeps upon 

 the bodies of bees, such as Antho- 

 phora and Andrena, who carry it to 

 their cells, wherein their eggs are 

 situated. The triungulin feeds 

 upon and destroys the eggs of its 

 hostess. Meanwhile its inactive life 

 in the bee's cell reacts upon the 

 organism ; after moulting, the second larval form (Fig. (UO, &) is 

 attained, and now the body is thick, cylindrical, soft, and fleshy, and 

 it resembles a lamellicorn larva, with three pairs of rather long tho- 

 racic legs. This is Riley's carabidoid stage. This second larva feeds 

 upon the honey stored up for the young or larval bees. After
