MR. E. B. POXJLTON ON THE PROTECTIVE [Mar. 1, 



Table V. 



Species and Class or 

 Order. 



Protective resemblance, or habits of concealment, evasion, &c. 



Hemipteea. 



Aphis hedercB and Aphides, 

 sp. ? 



4. Imagines of other Insects and a few Aethropoda 



Aphis hcderee is dark and inconspicuous ; aphides are generally inconspicuous, 

 but probablj also, in some cases, protected in other ways (taste or smell). 



Hcmipteron, sp. ? 



The species made use of was inconspicuous ; but many possess warning-colours. 

 The species was, however, evil-smelling, Uke the brilliant ones. 



DiPTEEA. 



Muscidse of various species 



Musoa domestica and M. vomiioria chiefly employed ; but also any other 

 Muscidae which could be found. The appearance, and especially the rapid 

 flight and readiness with which they are disturbed, are strongly protective. 

 Larvffi and pupae also made use of : both concealed. 



Eristalis and Si/rphtcs 



Probably the commonest species. Although somewhat less weH-concealed than 

 many species of Musca, many of the species of these genera are even stronger 

 on the wing. 



Tipula olcracea. 



Inconspicuous and easily disturbed 



Bibio marci 



The common male is black and inconspicuous : the much less common female 

 orange-coloured and easily seen ; both fly readily when disturbed. 



CoiiEOPTERA. 



Melolontha vulgaris 



The brown colouring is certainly protective ; flight in the evening 



Carabus hortensis (Fabr.).. 



The dark colour and habits of concealment are certainly protective. Noc- 

 turnal habits also. 



Omaseus melanarius. 



As above, the species being similar in habits and appearance, only much 

 smaller. Nocturnal habits. 



Hymenopteea. 

 Trichiosoma lucorum 



Dark colours and flight are evidently protective. 



Cocoons of Ants, sp. ? 



Carefully protected, being well concealed in the galleries &c.
