1. The tomentum which covers the cuticula (except the wing membrane); Aculeae usually form a dense covering in adults but are normally sparse or absent in immatures

2. Since the cuticula ofP. regalis is very extensible, the separation of different developmental stages was only reliable by using the measure of the strongly sclerosed anal plate.

3. Because the larvae and remnants of larval cuticula could be demonstrated in the pericardium and in the pericardial adhesions this type of pericarditis is referred to as pericarditis verminosa.
