Genus Limnochares {Latr.).

 sketch of ditto. 



This species is vivid scarlet. Its young is also very like that of 

 Trombidium holosericeum, has only six feet, and adheres to 

 Gerris lacustris, a water bug, and other water insects, generally 

 near the head, and although a Avater insect, has no ciliae to its 



Limnochares holosericeus. About \\ lines in length. 



legs or swimming powers, but creeps slowly over the mud and 

 plants under water. The body is irregularly oval, cone-shaped 

 in front, but from its softness is susceptible of accidental or 

 spontaneous deformation, so that it varies in appearance and 

 form. 



Genus Thyas {Koch). 

 More nearly resembling a Hydrachna, but feet adapted for 

 walking.
