varieties, and some hybrids; Mr. Nicholson, examples from Wales of 
the form callunae ; Mr. V. Eric-Shaw, callunae from the coast land 
opposite to the Isle of Arran ; Mr. C. P. Pickett, examples of true L. 
quercus from Sandgate, Deal and Folkestone, in all of which localities 
the exhibitor had found the species abundant. 
Paper. —Dr. T. A. Chapman read a paper entitled “Notes on 
Luffias.” He said that there were only two definitely ascertained 
species to deal with—L. ferchaultella and L. lapidella. The former 
was able to reproduce parthenogenetically, while the latter presented 
no such phenomenon. It was a matter of uncertainty whether under 
this latter species there were several species or not. Doth L. ferchaul¬ 
tella and L. lapidella were lichen feeders. Upon the question of the 
actual number of the species, Dr. Chapman considered that L. viag- 
giella ought to rank as a third species, or otherwise we might maintain 
only one species with different geographical phases. /,. ferchaultella 
occurred on the coast at Cannes and reproduced parthenogenetically. 
L. lapidella occurred at from 1,000-2,000ft. elevation, but not at 
Cannes. Its cases had also been found at some English places on the 
South Coast. In endeavouring to separate the species, too much 
reliance was not to be placed on the number of joints in the antennae, 
as in some specimens the joints appear only partly separated. Some 
very valuable details and philosophical comments followed upon 
parthenogenetic reproduction. A very interesting and valuable fact 
adduced was that if one sex gains preponderance, there is in many 
cases a prepotency to produce the opposite sex. With regard to the 
species under review, it was stated that, apart from the partheno¬ 
genetic trait, each species was very closely related to an ordinary non- 
parthenogenetic form. In his concluding remarks Dr. Chapman said 
that the genus Luffia might be considered as forming a bridge between 
the Macro- and Micro-Psychids. Mr. Kaye proposed a vote of thanks, 
which Mr. Nicholson seconded, and which was carried unanimously. 
Notes on Lasiocampa quercCs. —Mr. Bacot read some detailed 
notes drawn up by himself, with the collaboration of Mr. Warburg, on 
Lasiocampa quercus . Mr. Heasler proposed a vote of thanks, which 
Dr. Chapman seconded, and which was carried unanimously. 
Feb. 5th, 1901 .—New member elected. — Mr. James Stiff', of 8, 
Thornton Hill, Wimbledon, was elected a member of the Society. 
Spilosoma lubricipeda. — Mr. May exhibited a series of Spilosoma 
lubricipeda bred from a single batch of ova received from Barnsley in 
June, 1898. From the resulting imagines he judged that probably 
the parents were of the form radiata true, and an intermediate between 
that and the type lubricipeda. Selected from this brood, an inter¬ 
mediate $ was paired with a typical $ , the result being a number of 
$ s like the $ parent, but only three varieties among the 9 s, two 
being radiata and one a strongly-marked intermediate. A large per¬ 
centage of both sexes were quite typical. 
Special exhibit ok Hydiuecia nictitans. — A special exhibit of 
llydroecia nictitans was held, according to announcement at the 
previous meeting. Mr. Front exhibited a cabinet drawer containing a 
long series, with many of (he forms erythrostiyma, paladin, and luccns.
