THE ENTOMOLOGIST’S WEEKLY INTELLIGENCER. 
some numbers. From what I can learn 
it seems difficult to meet with, and in the 
hope that this hint will drive workers 
into the field I send this for publication. 
Perhaps somebody may be fortunate to 
meet with — in the puff-balls — Dorcatoma 
Bovistce and Cryplophagus Lycoperdi . —

OBSERVATIONS. 
Domhylius major. — I wish some of 
your readers who have the opportunity 
would watch this interesting fly, which is 
now on the wing, and, if possible, ascer- 
tain upon what species of bees it is para- 
sitic in this country, and so endeavour to 
carry M. Leon Dufour’s discoveries a 
little further. It is certainly “ passing 
strange” that Mr. Smith’s twenty years 
spent amongst these insects should never 
have resulted in the discovery of the con- 
nection of this Dipteron with the subjects 
of his study, and about which the latest 
item of British information is “ Larva 
supposed to feed on the roots of plants ! ” 
As B. medius is also a spring insect, and 
abundant in the South, it would be well 
that its habits should also be studied. 
In 1831 I was much puzzled to imagine 
why B. minor, a summer insect, should 
pass its time flying in the face of a dry 
“scaur” full of the holes of the bees, 
rather than amongst the flowers which 
were all around the spot, but M. Dufour’s 
discovery affords the solution, though, 
never having met with the insect since, 
I have had no opportunity for further in- 
vestigation. — G. Wailes.

Having formed a Natural History class

Entomology, I shall be happy to obtain
