Mr. Champion exhibited a large number of Coleoptera 

 collected by Dr. Chapman, IMr. Edwards and himself in July 

 last, at Fusio in the Val Maggia, Macugnaga in the Val 

 Anzasca, and on the Simplon Pass. He called attention to 

 the great variation in colour of one or two common species of 

 the Cbrysomelid genus Orina, and said he believed that these 

 forms, which were known as 0. cacalia', Schrank, 0. speciosis- 

 sima, Scop., and under other names, all belonged to one 

 extremely variable species. 



Prof. T. Hudson Beare showed specimens of Dinoderus 

 minutus, Fab., obtained from bamboo-furniture in his house at 

 Richmond. They were the specimens refei'red to by Mr. 

 Donisthorpe, in a Paper in the Entomologist's Record, as 

 being specifically identical with the Dinoderus substriatus of 

 Stephens. 



Mr. H. Donisthorpe exhibited a larva-case of Clythra 

 quadripu7ictata taken from a nest of the red wood-ant — Formica 

 rufa. He commented upon the unsatisfactory state of our 

 knowledge as to the food-habits of the larvse of Clythra, and 

 said it was stated the larvje fed upon the eggs of the ant, 

 though some observers considered them to be aphidivorous, 

 wliile others thought that pollen was their natural food. 



The President remarked that there was a species of 

 Microdon, of which the pupa-case had an obvious similarity 

 to the larva-case of Clythra, and was, he believed, found in 

 the nest of the same species of ant. 



Mr. Gahan mentioned as an interesting fact, not previously 

 recorded, in connection with the genus Clythra, that these 

 beetles possess a sti-idulating organ oil the meso-notum, not 

 along the middle as in Longicorns and Megalopidse, but towards 

 the lateral edges, and consisting of two widely separated 

 striated areas over which the edge of the pronotum moves. 

 The stridulating areas were present, he said, in nearly all the 

 genera of Clythridse, and might almost be regarded as a 

 characteristic of the family. The fact that these beetles 

 stridulate was apparently known to Darwin, who, in the 

 " Descent of Man," erroneously stated -that the stridulating 

 area was situated on the pygidium.
