 respective stages of the various nauseous or dangerous insects. 



Ring-patterns. — Especially suited to the cylindrical body-form, 

 such as tliat of larvae, pupee, or of images with colourless wings 

 (Hymenoptera &c.). Accordingly we find this pattern developed in 

 such stages, and it is also often suggested on the visible part of the 

 body of other forms. 



Longitudinal Stripes.— Aho especially suited to the cylindrical 

 body-form, and accordingly it is entirely found in larvae and in the 

 attenuated images of the genus Telephorus. 



Spots. — Especially suited to a wide coloured expanse, such as 

 that provided by the wings of Lepidoptera or the elytra of many 

 Coleoptera, but also fairly adapted to the cylindrical body-form, and 

 accordingly it is characteristic of conspicuous Lepidopterous and 

 Coleopterous images, only two of the four included larvae possessing
