HYMEXOPTERA. ACULEATA. 241 



to be found asleep in flowers, to which it is attached 

 by the jaws (see fig. 62). In the female of this Bee the 

 antennae are very short. 



Heriades closely resembles Chelostoma, and contains 

 only one, and that a very rare species. 



Ceratina is without the pollen-brush on the abdomen, 

 but has long hairs growing sparsely on the legs ;* 

 it contains only one species certainly indigenous, and 

 that is not common. It may be recognised by its glossy 

 blue body, and the club-shaped form of its abdomen. 

 It has, owing to the absence of polleniferous organs, 

 been suspected of parasitism, but Mr. Smith has seen it 

 in the act of excavating a dead bramble-stick. The sub- 

 marginal ceils are three in number. 



The fourth sub-family is the Scopulipedes (or brush- 

 legs). These Bees are furnished with a dense clothing 

 of hairs on the hind-legs of the females. 



The first genus, Eucera, contains but one species, the 

 male of which is instantly to be recognised by the great 

 length of the antennae, which is equal to that of the 

 body. As the Eucera is a colonizing Bee, it is easy to 

 find males and females at the same time, at the end of 

 May and in June. The antennas of the females are not 

 remarkable. 



This Bee burrows six or eight inches deep in the 

 earth, forming for its larvae a curious oblong-oval brown 

 cell of thin material, in which it places both larvae and 

 food. A colony of these Bees, settled on the green slope 

 of a garden-plat or lawn, is a most enlivening addition 

 to the pleasures of the garden. The males are busy, 



* It is on the ground of general affinity that this Bee is placed among 

 the Dasygastrse notwithstanding the absence of the abdominal hairs.
