THE ENTOMOLOGIST. 299 
Gynandromorphism in Hymenoptera.—Mrx. Smith exhibited 
examples of gynandromorphism in Aculeate Hymenoptera, 
and read the following notes:—“1. In 1836 I took Antho- 
phora 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 
antennez 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 intermediate 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.” 
Lepisma saccharina.—My. 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,’
