Mr. Main exhibited some enormous larvae in spirit from 

 the West Coast of Africa. Probably they were of some large 

 species of Longicorn beetle. 



Mr. Lucas exhibited one of the Entomostraca, Branchippus 

 stagnalis, taken, on May ioth, from a cart-rut in Princes 

 Covers at Claygate. It was a most delicate and beautiful 

 member of the tribe Branchiopoda. According to Hogg the 

 species is usually found in cart-ruts and other small pools 

 after heavy rains. Carpenter says it is comparatively rare in 

 this country. 



Mr. Gilbert J. Arrow exhibited Geotrupes stercorarius, G. 

 sylvaticus, and G. typhosus, all British, with G. sharpi, from 

 Burma, and G. aurata, from Japan. The last-named was 

 metallic, an unusual character in this family. He also 

 exhibited a larva of Geotrupes. In the same family he showed 

 Copris hispanicus, from France, C. lunaris, a rare species in 

 Britain, and a specimen of a new species from Angola, of 

 which only one other is known to exist. In the Passalidce he 

 showed Neleus unicornis, from Trinidad, set up to show the 

 abdomen and vocal apparatus, together with the larva of N. 

 interruptus, the largest species of the family and wingless. It 

 was from South America. 



Mr. Arrow then gave an address on " Some Social 

 Beetles," of which the above were in illustration. In the 

 discussion which took place it seemed that but little was 

 known of the use of sound apparatus in larvae. There were 

 various suggestions that they were more or less directly or 

 indirectly protective, either to the individual as warning 

 signs, or to the species as a whole, in collecting together 

 those individuals which had wandered too far. 



MAY 2$tk, 1905. 



The President in the Chair. 



Messrs. Harrison and Main exhibited a large number of 

 species of Lepidoptera captured or bred this season from 

 various southern, south-western, and north-western localities 

 in England, and pointed out the local characteristic forms 

 of the various species. 



Mr. Carr exhibited various spring species of Lepidoptera, 

 mainly from the New Forest. 



Mr. Joy exhibited a short bred series of Thecla rubi. He 

 stated that he had searched dog-wood for larvae of Cyaniris
