sanguineum, 3, from Epping Forest (September 15th, 1907), 
the form of the left hind-wing suggesting relationship with 
certain Orthoptera, which order is of course closely related to 
the Odonata. He further exhibited two Calopteryx virgo of 
his own from the New Forest showing failure in wing 
pigment. 
Lire Cycie or CaLiicorE aureLia.—Mr. W. J. Kaye 
exhibited specimens of Callicore auwrelia, Guen., together with 
a photograph of its larva, showing the remarkable branch-like 
horns rising out of the head. Mr. L. Guppy, who is rearing the 
species in Trinidad, and writing a detailed account of its 
life history, has found that the eggs hatched in four days : 
the larval period was eight days only, and the pupal period 
seven days. ‘The whole life cycle was thus but nineteen 
days. 
TERATOLOGICAL SPECIMEN oF A BrE.—The Rev. F. D. 
Morice exhibited, side by side, a normal 3 specimen of the 
bee Anthidiwm manicatum, L. (the “ Hoop-shaver bee”’ of 
Gilbert White’s “ Natural History of Seiborne”), and a mon- 
strosity or malformation of the same insect, which was long 
ago given to him as a curiosity by his correspondent, M. 
Vachal of Argentat, Corréze, France, but which he had only 
lately found opportunity to examine minutely. He also sent 
‘round a photograph of the two insects magnified, or rather of 
their abdomens, that being the part in which the malformation 
appears, and described the nature of it. 
Normally in this species the ¢ abdomen viewed from above 
shows seven dorsal plates united only by a (concealed) ‘“ con- 
necting membrane.” ‘The first five are nearly simple, but the 
sixth bears on each side at the base a remarkable hook-like 
process, and the seventh is armed at the apex with three large 
sub-triangular teeth, one on each side of the apex ando ne at 
its centre. In the present specimen, if we count the divisions 
between the dorsal plates down either side, we find that there 
are, as usual, on each side 5 simple dorsal half-plates, followed 
by a sixth with a basal lateral hook, and a seventh whose apex 
is armed externally with a tooth and internally with half a 
tooth. But when we look at the dorsum of the abdomen as a 
whole, we find that something has gone very strangely wrong
