i9t9. Johnson. — Aculeate Hymenoptera. 7 



These insects are like the Cuckoo among birds. They make 

 no nest of their own, but place their eggs in those of other 

 species, e.g., Andrena or Euceros. The curious thing is 

 that these intruders are not interfered with by the pro- 

 prietors of the nests they invade. 



The Wasps and Bees of which I have been writing are 

 all solitary, and there are only males and females ; but in the 

 Humble Bees (Bombus) we have, as in the Ants, Social 

 Wasps and Hive Bees, workers as well as males and females, 

 and the species live in communities. The females hybernate 

 and in the spring start the nest and new brood, which 

 increases in numbers as the season advances. The Humble 

 Bees differ in the places they make their nests. Some, e.g., 

 the common yellow and black Bombus lucorum, make their 

 nests underground like the Common Wasp ; others make 

 it on the surface among thick grass or in thick moss, these 

 latter are called Carder Bees, and the light yellow and red 

 Bombus musconim is a typical example. In the following 

 list the species from Tempo were taken in the Manor grounds 

 in the end of May ; those from Portnoo, unless otherwise 

 dated, were taken in June.
