Ecchibitions, &c. 
Mr. Bond exhibited four specimens, two males and two females, of a Lasiocampa 
bred by Mr. Robert Mitford from larve found on the coast of Kent; he regarded them 
as merely a variety of Lasiocampa trifolii, differing from the normal form in colour 
and in the antenne of the male, though he was informed that the Jarve also differed 
and were of a golden colour. The insect might be supposed to bear the same relation- 
ship to L. trifulii that L. Callune bears to L. quercus, and had very much the appear- 
ance to be expected in a hybrid between Lasiocampa trifolii and Odonestis potatoria. 
Other bred specimens of L. trifolii, from Cumberland, Hants, Dorsetshire and Devon- 
shire, were produced for comparison. 
Mr. Bond also exhibited several Fritillaries with unequally developed wings; and 
a remarkable variety of Dianthecia capsincola from York. 
Mr. Bond offered an explanation of the curious habit of Macroglossa stellatarum, 
frequenting stone walls, &c., as to which an enquiry was made at the previous 
Meeting (ante, p. xlix.). The object was to secrete itself in some hole or crevice: he 
had often noticed that the insect had a morning and an afternoon flight, but in the 
middle of the day grew tired, when it would seek out a wall or bank and creep up it 
until it found a hole or cranny wherein -to rest. 
Dr. Wallace corroborated this: when residing in the Isle of Wight he had observed 
the humming-bird hawk-moth resting in crevices of mud banks, &c., and on one 
occasion he had captured in a limpet-shell a specimen which was thus reposing. 
Prof. Westwood exhibited a singular variety of Mamestra brassice caught by Mr. 
Briggs, of St. John’s College, Oxford. Mr. Bond mentioned that he possessed a 
similar specimen. 
Dr. Wallace said that on recently looking through Dr. Bree’s collection of British 
Lepidoptera he had detected a Platypteryx Sicula mixed up with P. falcataria. The 
insect did not bear any label, and Dr. Bree had not any recollection of the capture of 
the particular specimen, though he had no doubt that it had been taken by himself 
some years ago along with P. falcataria in the neighbourhood of Stowmarket. If so, 
this was a new locality for the species, which in this country had hitherto been known 
to occur only in the neighbourhood of Bristol. 
Mr. G.S. Saunders exhibited a nest formed by social caterpillars among the leaves 
ofa Brazilian tree, a species of Zeyhera; it was about a foot in length, and formed a 
compact web between two small branches. The nest was collected in 1866 by Senor 
J.C. de Mello, at Campinas, Province of S. Paulo, and by him sent to Mr. Daniel 
Hanbury. 
Mr. Wormald exhibited a collection of insects sent from Shangkai by Mr. William 
Pryer, amongst which was a single specimen of a wild Bombyx, having some 
resemblance to B. Huttoni. 
Dr. Wallace exhibited an English cocoon of Bombyx Yamamai, one of two reared 
in 1866, at York, by Mr. Dossor. 
Dr. Wallace also exhibited numerous specimens of the cocoon and imago of 
Bombyx Cynthia, and the silk thereof. One was a double cocoon, the joint work of 
two larve. Another cocoon, formed in 1865, and which in due course ought to have 
produced a moth in 1866, contained a still living pupa, which would probably hatch in
