GEOGRAPHY OE THE GENERA.

are Germany, Sweden, a part of Russia, and even Fin¬ 
land. It is impossible for any entomologist to examine 
every locality for himself, lie must, in great measure, 
depend on the labours of others; and, of course, I can 
only speak of the collections which are accessible to me, 
or which are described in monographs, or have been 
named in lists that have been published. Doubtless the 
Museum of Berlin, so long under the administration of 
a lover of the Order, Dr. Klug, would present a large 
contribution to our knowledge of the distribution of the 
forms, did a list of its riches exist. Such a list of the 
menoptera of Portugal, contained in Count Hoffman- 
segg’s collection, was published many years ago in Illi- 
geFs f Magazin der Insectenkunde./ 
It has been a fatality incidental to this entomological 
branch of the study of natural history that some of its 
most energetic cultivators have been taken early away. 
There was formerly Illiger, then our own Leach, and 
then Erichsen. Leach, but for his afflicting malady, 
would have done much for the science; still, let us 
hope that the Hymenoptera, and especially the bees, are 
gaining ground in the estimation of entomologists gene¬ 
rally, and that not many years will pass before collec¬ 
tors will possess them in abundance. For the present, 
I can but give a slight summary of the knowledge we 
possess on this subject. 
Thus science has sustained great loss by reason of the 
unfortunate neglect which the family of bees, and, in¬ 
deed, the Order of Hymenoptera generally, has met with 
from collectors in distant localities whose tastes have 
led so directly to the collection of other more favoured 
Orders, and the opportunities for repairing the conse¬ 
quences of such neglect being in some cases extremely
