Exhibitions. 



Mr. M. Burr exhibited an earwig, Apterygida arachidis, 

 Yers., found by Mr. Annandale of Calcutta, in a box of 

 specimens received from the Andaman Islands. When placed 

 in a small box, it was alone, but next morning there were five 

 larva? present ; two disappeared, apparently being consumed 

 by the parent ; and the remaining three were those exhibited. 

 Mr. Burr also showed a Locustid of the family PseudophylUdx 

 taken in Queensland by Mr. H. W. Simmonds, a Fellow of the 

 Society, among twigs and plants which it greatly resembled, 

 together with a photograph of the insect in its natural 

 position. 



Mr. E. C. Bed well showed (1) three examples of Gnorimus 

 nobilis, L., taken at Woolwich on May 20th last under the 

 bark of an old dead cherry tree, a beetle of which Canon 

 Fowler writes that it seems to be becoming extinct in 

 Britain ; and (2) a malformed specimen of Lochmsea suturalis 

 which had the left posterior tibia bifid for about one-third of 

 its length, and two tarsi, one of which had the joints 

 considerably enlarged. 



Mr. O. E. Janson brought for exhibition a living specimen 

 of Omop/dus betulse, Herbst, a beetle not known to occur in 

 Britain, found by his son near Covent Garden, and probably 

 imported. 



Mr. W. J. Lucas exhibited one <$ and three ? 9 of Agrion 

 armatum taken this year by Mr. F. Balfour Browne and sent 

 to him alive. This dragonfly, scarce everywhere, was added 

 to the British list by Mr. Browne about two yeai\s ago. 



Mr. G. C. Champion showed four specimens of the rare 

 Acrognathus mandibtdaris, Gyll., captured on the wing towards 

 sunset near Woking at the end of May. 



Mr. Selwvn Image exhibited two aberrations of Biston 

 hirtarms, both females, taken by himself at rest on tree- 

 trunks at Mortehoe, North Devon, April 23rd, 1905. The 

 first aberration was tolerably normal in general coloration, 

 but the anterior half of the fore-wings was much suffused 

 with fuscous, and at the costa broadly emphasized with rich
