258 C. D. SOAR ON THE WORK OF THE LATE SAVILLE-KENT 



on Wandsworth Common. Ova deposited April 26th, larvae 



appeared May 21st. It is a very common species. There are 



several slides of this mite, some not fully developed, others of 

 larvae.

 1868. Saville Kent in connection with this mite has the 

 following interesting note : " According to Duges this animal 

 deposits its ova in the tissue of water-weeds, first piercing 

 suitable orifices with its mandibles in the water- weeds. Sent me 

 from Chertsey were many dead specimens, which after piercing the 

 tissue had evidently been unable to withdraw their mandibles and 

 consequently perished. A remarkable aberration from the general 

 habits above quotetl was instanced by a specimen depositing its 

 ova at the extremity of a long pedicle, and which can only be 

 accounted for on the supposition that the texture of the weeds 

 was of too firm a nature to allow of the animal pursuing its 

 usual course." As well as the above note Saville-Kent gives 

 a slight sketch showing how the eggs appear at the top of the 

 stalks similar to those of the lace-winged fly, Chrysopa perla^ 

 only the stalk is much shorter in the water-mite.
