THE ENTOMOLOGIST. 95 



Laboulbeiiei, and of very extraordinary habits, the larva being 

 aquatic, living in the canals of the sugar plantations in 

 Cayenne, and feeding upon an aquatic plant. The hairy 

 larva had all the form usual for the group, and breathed by 

 means of small spiracles, — a supply of air being apparently 

 entangled in its hairs. The cocoons were joined together in 

 little masses floating on the surface of the water. 



Olivierian Collection. — Mr. M'Lachlan read a letter that 

 he had received from M. Ernest Olivier, stating that the 

 collection of insects formed by his grandfather had been 

 purchased some years after his death by MM. Chevrolat and 

 Jousselin. A great part of the collection had been suffered 

 to fall into decay ; but recently a portion, comprising the 

 Curculionidffi, Ueteromera, Laniellicornes, Sternoxi, Chryso- 

 melidae, Clavicornes and Hydrocantharidae had come into his 

 possession, and he would be happy to show them to any 

 English entomologist who might desire to examine any of the 

 numerous types. Unfortunately the Carabidse and Longicornes 

 were almost entirely lost. 



Election of Officers. — The following gentlemen were elected 

 Members of Council for 1874: — Sir Sidney Smith Saunders, 

 Messrs. W. C. Boyd, Dunning, Grut, Meldola, Moore, 

 M'Lachlan, F. Smith, Stainton, Stevens, Verrall, Jenner 

 Weir, and Professor Westwood. The following officers were 

 subsequently elected, viz.: — Sir Sidney Smith Saunders, 

 President; Mr. M'Lachlan , Treasurer ; Messrs. Grut and 

 Verrall, Secretaries; and Mr. Janson, Librarian. The Presi- 

 dent then read an Address on the progress of Entomology 

 during the past year. 



Insects in Limestone Caves. — Mr. Miiller exhibited the 

 following specimens, which lie had found on a recent visit to 

 some limestone caves in the Jurassian Mountains. 1. A 

 blind Myriapod, found on decayed trunks of trees carried into 

 the cave by floods. 2. A minute Podura, which had, how- 

 ever, become quite shrivelled. 3. A species of Ha^malastor, 

 Koch (a genus of Schusselzecken), mentioned by Kolenati in 

 'Die Parasiten d. Chiroptera' (Dresden, 1857). Mr. Miiller 

 did not observe any bats in the cave, but the insect was 

 creeping on one of the stalactites, from which it dropped into 

 his hand. He believed it was the first time that any blind 

 specimens had been found in the caves of Switzerland. 



Longicorn destructive to Coffee Plantations at Natal. — 

 The Secretary read extracts from a letter from Mr. W. D.
