THE ENTOMOLOGIST. 299 



Gynandromovphism in Hymenoptera, — Mr. Smith exhibited 

 examples of gynandromorphisra 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 antennae, 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 

 antennae having in the male sex the front side white, and also 

 a white line at the inner margin of the ej^e, 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. Antennae 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. — 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 thera 

 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,'
