140 FAUNISTIC NOTES 



ANTS, BEES, AND WASPS 



BY W. E. HILEY AND A. H. HAMM 



The plumed insects swift and free 



Like golden boats on a sunny sea 



Laden with light and odour, which pass 



Over the gleam of the living grass. SHELLEY. 



HYMENOPTERA ACULEATA. HETEROGYNA 



Lasius niger, L. This common garden ant is abundant in the grounds 

 and houses. 



Myrmica rubra, L. Common in the grounds. 



Plagiolepis flavidula, Rog. This exceedingly small exotic ant is some- 

 times abundant in the Palm and Orchid Houses. It is a native 

 of S. America, Cuba, etc., and is also found in the hot-houses 

 at Kew and Cambridge, no doubt having been introduced with 

 plants from abroad.

Trypoxylon figulus, L. Vespa sylvestris, Scop. 



Stigmus solskyi, Moran. ^ Austriaca, Panz. This 



Psen pallipes, Panz. is a m ost interesting wasp, 



Crabro tibialis, Fab. as it makes no nest, but is

Vespa vulgaris, L. Odynerus parietum, L. 



,, germanica, L. ,, gracilis, L. 



,, rufa, L. ,, callosus, Thorns. 



BEES are of especial interest in a Botanic Garden, since the careful 

 watching of their habits enables the observer to see some of the complex 

 floral mechanisms at work. With some exotic plants, such as those 

 pollinated by humming birds, it is impossible in England to see the 

 flowers pollinated as they are intended to be ; but for most garden types 

 the English insects are sufficient, overcoming by their ingenuity the 

 difficulties of mechanisms formerly unknown to them. The following is 

 a list of the bees recorded for the Botanic Garden :
