Cases of Protective Resemblance, Mimicry, etc. 363 



Cekambycid^:. 



Aromia moschata, L. 



Mr. Holland suggests, " This beetle is very like the 

 specially protected Cantharis." It smells strongly of 

 musk, and sits about in a conspicuous manner on umbels, 

 etc. ; it is most probably distasteful on its own account. 



Hylotrupes bajulus, L. 



Mr. Holland points out that the smaller forms of this 

 beetle are " wonderfully like a species of Telephones." 



Callidium variabile, L. 



This Longicorn is also very like a Telephones. It has 

 two forms, a blue and a red, as have several species of 

 Telephones. 



Callidium alni, L. 



This pretty little beetle, with its red and white stripes 

 on a black ground, is a good mimic of a Mutilla. 



Clytus arietis, L. 



This beetle is black banded with yellow and bears 

 during life a strong superficial resemblance to a wasp. A 

 cabinet specimen closely examined is certainly not much 

 like the Hymenopterous insect, but when at large flying 

 about, and settling on stumps, as it loves to do, its move- 

 ments, combined with its colour, are very wasp-like. 

 Professor Poulton writes (Colours of Animals, p. 250) : " But 

 the most remarkable point in the resemblance can only be 

 appreciated by observing the living insect. When walking 

 the slender wasp-like legs are moved in a rapid somewhat 

 jerky manner, very different from the usual stolid cole- 

 opterous stride, but remarkably like the active movements 

 of a wasp, which always seem to imply the perfection of 

 training." It is also probable that it is distasteful in itself 

 as Mr. Shelford shows that the Clytinte, as a group, in 

 Borneo are much mimicked by other Longicornes (Brit. 

 Ass. Keport, 1900, p. 795). 



Clytus mysticus, L. 



The colours of this beetle afford a good likeness of a 

 Mutilla.
