192 THE ESSEX NATURALIST.
G. vulgaris Schrad var. aurantiaca Pers. N. In "The
Warren" spinney.
Reticularia Lycoperdon Bull. Two weathered aethalia on,
logs. One of them contained numerous membranous empty
insect cocoons ; the specimen was sent to Dr. W. G. Blair at
the British Museum, who kindly tells me that Dr. F. W. Edwards
identifies them as those of a fly, Epicypta testacea Edwards, be-
longing to the family Mycetophagidae. On breaking this aetha-
lium across several small shining black beetles escaped, which
may have been the species Anistoma humeralis (Fam. Silphidae);
Dr. Edwards would be glad to have the larvae of both the fly and
the beetle sent him if they should be found at any time.
