THE ENTOMOLOGIST’S WEEKLY INTELLIGENCER. 
a notice of Siebold’s work ‘ On a true 
Parthenogenesis in Moths and Bees,’ ob- 
serves respecting the Solenobice, “ Eggs 
are produced independent of the male 
influence, and the fact of such eggs pos- 
sessing vitality in the present state of 
physiology can scarcely he said to be 
marvellous. We expect that hereafter 
it will he proved that, under certain 
conditions, perfect males will always be 
formed, and sexual reproduction take 
place ; but if, as each generation lasts a 
year, it should ordinarily continue to be 
asexual as long as in the Aphides, it 
would take at least from nine to eleven 
years before the experiment was com- 
plete; and indeed it might require much 
longer, as we are entirely ignorant of the 
circumstances which may or may not be 
favourable. Indeed, we may be said to 
have positive proof that such will be the 
case, since the male of at least one spe- 
cies in which this parthenogenesis occurs 
is well known, namely, that of Solenobia 
inconspicuclla. The larvae of this moth are 
common amongst lichens, near London, 
and well deserve more attention than 
they have hitherto met with, even from 
entomologists. We ourselves have bred 
them, but only females, whilst in the 
allied genus Talrcporia we have fre- 
quently reared both males and females 
of Tahxporia pseudo-bombycella : and 
curiously enough, we almost feel assured 
that no parthenogenesis takes place in 
this species.” 
As the season of the year for collecting 
Solenobia larva has now returned, we 
trust that all our readers who lake an 
interest in the subject will be on the 
alert. Mr. Edleston, in the January 
number of the ‘Zoologist,’ p.5927, re- 
cords a new British species of Sole- 
nobia bred from “ cases found on and 
under mill-stone, grit-stone, he., on the 
moors.” Is this the same as the Arthur’s 
Seat species, of which no males are 
known ?
