52 BOLETOBIA FULIGINARIA. 
uniform balance of moisture in growing the fungus 
upon which the larva fed for three weeks after I 
obtained it. 
The life-history of Boletobia fuliginaria appears to 
be summed up as follows :—Ova deposited end of July 
or beginning of August; larves hatch in August, and 
after hybernation continue feeding until the end of 
June of following year, when the pupa state lasts 
about three weeks, and the perfect insects appear about 
the middle of July. (W. H. Tugwell, July 20th, 1884 ; 
Ent., August, 1884, XVII, 183.)

Plate CXIV, fig. 5. 
Last summer (1864) Mr. Mclachlan kindly sent 
egos of this species to Mr. Buckler and myself, and 
we were successful in rearing several larvae. I should 
not, however, have said anything about them, had they 
not been of a variety differing considerably from that 
to which the description by Borkhausen in Stainton’s 
Manual must refer. | 
The larve were hatched on the 30th June, 1864, 
being then of a saffron-yellow colour. ‘They chose 
for their food whitethorn, especially preferring the 
young pale summer growth, and the tender shoots 
thrown up from stems cut off close to the ground. 
That they should make this choice, and thrive on it, 
seems strange, for I have generally observed that the 
summer growth of trees and bushes is not such whole- 
some food for larvee as the older firmer foliage. 
Some of this batch of N. viridata escaped, and I 
afterwards captured one of the runaways feeding on a 
withered poplar leaf; but this was evidently only from 
starvation, and the larva never recovered sufficiently 
to become a pupa. 
The remainder of them were full-grown about the 
last week in August, being then about seven-eighths
