Mr. F. Smith exhibited examples of gynandromorphism in Aculeate 
Hymenoptera, and read the following notes :— 
“1, In 1836 I took Anthophora acervorum, in the month of April, at 
Barnes, Surrey. In this example the male characters are very conspicuous, 
and are all situated on the left side, most conspicuously so in the head, 
thorax and legs. This specimen is figured in the ‘ Zoologist,’ vol. iii., and 
also in my book on British Bees. 
«2. A second example of Anthophora acervorum is in the collection of 
the late Mr. Walcott, of Bristol; but the sexual peculiarities of structure 
are much less apparent than in that exhibited. 
«3, Andrena thoracica. In this specimen the male characters are on 
the right side, and are observable in the antenne, head and legs. 
«4, Nomada baccata. In this specimen the male characters are found 
to be on the left side; the head is about equally divided sexually; the 
antenne having in the male sex the front side white, and also a white line 
at the inner margin of the eye, and the face covered with silvery hair; the 
male mandible is longer and pointed at the tip; in the female it is blunt. 
The thorax is coloured as in the female. The abdomen exhibits a strange 
peculiarity; the apical segment above is blunt, as in all the females of the 
genus, whilst beneath it is acute; there are the usual six segments above, 
beneath there are seven. Taken at Weybridge in 1845. 
«5, Apis mellifica. A monstrosity, partly male, partly worker. Antenne 
worker on both sides; eyes worker; left anterior leg male; the right inter- 
mediate leg and also the posterior one male; the abdomen has the silky 
gloss of a male, and is in form partly so, being more blunt at the apex: the 
male organ of generation is partly protruded. This specimen was sent to 
me by Mr. Woodbury, of Exeter.” 
Mr. W. A. Lewis called attention to the ravages reputed to be occasioned 
to books by Lepisma saccharina, with reference to Mr. Quaritch’s statement 
made before the Society at the Meeting held on the 3rd of January, 1870. 
Although it was acknowledged that Lepisma damaged books by eating the 
paste of the bindings, thus causing them to fall to pieces, yet it had been 
considered impossible for it to bore holes in the books, as stated by 
Mr. Quaritch, such ravages being considered due to Anobium. However, 
upon referring to Dr. Packard’s ‘ Guide to the Study of Insects,’ Mr. Lewis 
found that the author (p. 623) endorsed the opinion that Lepisma is a

Mr. Horne alluded to the damage done to silk garments in India 
by Lepisma; the insect evidently attacking the silks on account of
