BOLETOBIA FULIGINARIA. 51 
The colour and markings then were very much of the 
same character as the now (June 14th) full-fed 
larva, which is about seven-eighths of an inch long, 
moderately stout for a geometer larva, cylindrical in 
form, attenuating slightly at the anterior and posterior 
segments. The ground colour is of a sooty-black, the 
dorsal line marked by ten pairs of orange-coloured 
raised tubercles, two on each segment. The four 
central segments have also a second pair of smaller 
and less distinct tubercles, from the region of which 
spring longish and curiously recurved hairs. The 
spiracular line is also indicated by a row of raised 
orange-coloured tubercles. 
When full-fed it spins up in the crevices of the 
rotten wood, and forms a fairly compact cocoon of 
ereyish silk, the outside being coated with particles of 
fragments of wood and dried fungus. Three old 
cocoons, from which Mr. Upton had bred some of his 
insects last year, were handed to me, and these show 
most markedly the character of the wood on which 
grew the fungus where I saw the larva feeding in a 
state of nature. 
I forwarded a portion of this fungus-covered wood 
to Dr. M. C. Cooke, who is one of our ablest autho- 
rities on British fungi, and he most kindly determined 
it for me as an effused Muscedine, order Hyphomycetes, 
fam. Muscedines (see his ‘ Handbook of British Fungi,’ 
p. 587). Dr. Cooke could not determine the genus, 
as it was not then in the stage of development 
necessary for identification. 
The larva was full-fed, and duly spun up its charac- 
teristic cocoon, on the 25th June. (W. H. Tugwell, 
June 14th, 1884; Ent., July, 1884, XVII, 153.) 
I was much gratified by finding, on the 14th of July, 
that an imago had emerged from the pupa mentioned 
above. ‘The insect is a perfect female, and is a trifle 
smaller than those bred by Mr. Upton from pupx 
collected in their native habitat. This was doubtless 
caused by the difficulty I experienced in retaining a
