Glyciphagus domesticus on Tortoises. 
The household mite Glyciphagus domesticus was sent by the Rev. 
J. Harvey Bloom, of Whitchurch Rectory, taken from domesticated 
tortoises. This species is found in all manner of places, and may be 
found on living creatures, but it is not their habitat. They are not 
parasitic at all, and it is doubtful if they would do the tortoises any 
harm, although they may cause some irritation if present m large 
numbers.

affected, and does not seem to be likely to send up ears.” 
The pest proved to be the common Gout Ely, Chlorops teeniopus. 
Certain differences in the place of pupation made it difficult to say at 
first, hence the doubt as to species in the following report sent : — 
“ The barley you send is attacked by one of the Gout Flies 
( Chloropidse ). 
“ It is probably the Ribbon-Footed Corn Fly ( Chlorops tseniopus), 
but, as a rule, that species pupates in the groove made by the larva, 
and not as in the specimens you send between the sheathing leaf and 
the damaged ear. It is a common pest all over the country, 
especially on poor soil ; on chalk lands it is, as a rule, most 
prominent. I think there is more than one species that does the 
damage. 
“ None of the plants as badly attacked as the ones you send will
