On dead leaves of Stellaria holostea. Common.
M. Desmazieres observes th a t this species often supports a minute para-
sxtio Dana, whence its name. I have never been able to find such a parasite,
although I have sought for it diligently. M. Westendorp makes a
similar observation of want of success in verifying the fact.
