138 THE ENTOMOLOGIST. 
The species has been recorded as double-brooded in Hants 
(Vict. Hist. Hamps. 147) as well as in Dorset (Prac. Hints, ii. 
84), with reference to which counties Meyrick (H. B. Brit. Lep. 
505) enters the first brood as appearing in May, and the second 
in July and August. The moths reared by Mr. Clutterbuck from 
South Devon on August 6th obviously belonged to at least a 
second brood, since the larve that produced them were found 
feeding in July, and the fact that my imagines of the first brood, 
bred from the same coast, only emerged in July and August 
was doubtless due to the larve and pupe being kept in a very 
cool place. I have taken the perfect insect on many dates in 
September, and having then noted it as common at the same 
time that larve of all sizes were abundant, think it not unlikely 
that there is, throughout the summer and early autumn, a 
constant succession of broods, with much overlapping, and no 
marked intervals between them. In any case, the probability of 
the occurrence of, at any rate, a third brood in South Devon is 
suggested by my having met with the imago in some numbers, 
and in fine condition, on September 24th—26th, and having 
captured in sugar, in 1906, a good example of the female as late 
as October 15th. 
The moth has frequently shown itself to be possessed of “‘a 
sweet tooth” by visiting this bait at some distance from its 
haunts, generally only in odd individuals, but more or less com- 
monly at times. When the weather conditions are favour- 
able it flies freely during the evening—not only ‘‘at dusk,” as 
stated by Wilkinson (Brit. Tort. 187 (1859) )— but is very difficult 
to net, its protective colour and rapid dashing flight preventing 
the eye from following it against the background of sand and 
shingle in which its food-plant grows. 
In my experience, the larva, when feeding in the autumn, 
gradually constructs, as a rule, a well protected gallery, of 
remarkable length, up the exterior of the stem of the shoot, by 
joining together with silk the leaves that grow thereon and 
drawing them in towards the stem; it works its way upward by 
degrees, and, as it progresses, eats out the contents of the 
indrawn leaves, whose bleached appearance then attracts instant 
attention to the situation of the larval gallery. It has often 
been observed devouring the seeds, but I do not happen to have 
found it feeding in this manner. A. consequana hybernates as 
a full-fed larva, spun up in an opaque dirty-ochreous cocoon 
formed of tough silk, and normally pupates therein in the 
spring, though some of my larve cannot well have done so 
before July. In confinement, certain individuals spun their 
_ cocoons among the pieces of the plant, whilst others fixed them 
against the bottom or sides of the cotton bag in which they 
were imprisoned; they seemed particularly fond of attaching to 
the outside of the cocoon any minute pebbles that could be
