Mr. C. O. WaTERHOUSE suggested that it was probably an 
abnormal specimen, six-jointed tarsi being so far unknown in 
Entomology. Mr. G. C. CHAMPION expressed concurrence in 
this opinion. 
VARIETIES OF APLECTA NEBULOSA.—Mr. A. Harrison ex- 
hibited a drawer of Delamere Forest Aplecta nebulosa, bred 
last year from var. robsoni 3 and var. thompsoni 9, by himself 
and Mr. H. Main. He said: “Only fifty moths were bred, 
26 / of the grey form, 42 / of robsoni and 32% of thompsoni. 
This result quite negatives our idea that the form robsoni was 
a heterozygote, or hybrid (so called) and that the grey form 
and thompsoni were homozygotes, or pure. We had been led 
to this conclusion by the results previously reported as being 
obtained by ourselves and by Mr. Mansbridge. From a large 
brood, both parents vobsont, we had previously bred 25 7 
grey, 51% robsoni, and 24 / thompsoni, obviously Mendelian 
proportions. From several broods, both parents grey, we had 
bred only the grey form. From the grey form crossed with 
thompsoni, Mr. Mansbridge had obtained only robsoni, and 
from the grey form crossed with robsoni he had bred 50 / 
robsoni and 50 / grey. These two latter broods were very 
small, but all the results pointed to the conclusion mentioned 
above, and appeared to be parallel to the well-known case of 
the Andalusian fowl, where we have also three forms, a black, 
a white (splashed with black or blue), and a blue, the latter 
being the hybrid, and the two former being pure. However, 
the results obtained last year show that the problem is not so 
simple as this, and that it will require further experiments 
before it can be solved.” 
FeMALEs OF Lastus mrxtus.—Mr. DonistHorPE exhibited 
three 99 of Lasius mixtus, Nyl., a race of L. wmbratus, Ny)., 
and a @ of the latter for comparison. He remarked that there 
were only two records of its capture in Britain—at Bickleigh, 
near Plymouth, by Bignell, and in the Isle of May by Grim- 
shaw, who both recorded ¢ 4, 2 2, and $9. One of his 
specimens was taken at Weybridge last year, and another at 
Mickleham, in company with Mr. Crawley, where they each 
took a specimen last month. The third was captured this 
year by Mr. Dollman in Richmond Park. He pointed out
