460 THE ENTOMOLOGIST. 
Economy of Sesia Tipuliformis.—Having cut open some 
twigs of the black and red currant last September, [ was 
astonished to find larve of the above of considerable size, in 
fact, nearly full grown to all appearance, being almost 
identical with those I have discovered in March and April. 
At other times, in splitting the stems and twigs in autumn, [ 
have found the larve small, and I supposed, with others, 
that they fed on slowly through the winter. It is the more 
remarkable that the larve should be large this autumn, 
because, in the same spot, the imagos appeared later than 
usual this year, and were not out until the second week in 
July. It seems, therefore, possible that some individuals of 
this species may pass two winters in the larval state. I hope, 
next year, to be able to make a careful examination of the 
bushes, during the time the perfect insect is out.—J. R. S.

Female Moths at Sugar.—The overwhelming majority of 
the female moths which resort to sugar will be found to 
be, as I believe, unimpregnated, and, hence, the eggs they 
deposit, while imprisoned, are not good for anything except 
microscopic objects. The chief object of the females, 
throughout their lives, is evidently the continuance of the 
species ; and, immediately they are prepared for the work of 
oviposition, they betake themselves to this with diligence, 
and neglect the attractions of sugar and flowers. It has been 
supposed by some that the organs of smell are much more 
acule in most male moths than in the females, and, were this 
the case, it would account for the admitted paucity of females 
at sugar. Anatomy, however, does not throw much light 
upon this subject; and, before we can decide as to the 
relative functions of the organs of smell in male and female 
moths, we must be able to answer, with positiveness, the 
question :—‘“ Where does the sense of smell reside ?”—

Hepialus lupulinus (second appearance).—This species 
is usually constant in its time of appearance, being on the 
wing, near London, in the early part of June, and seldom 
affected much by change in the temperature. I discovered, 
last September, specimens in good condition on palings, 
near Fulham; and as these were hardly likely to have been 
survivors of the June brood, there must have been a partial
