Remarks on the Modern Classification of Insects. 

 By Rev. F. W. Hope, F.R.S. 



The following is an outline of the communication : — 1st. That mo- 

 dei'n entomologists, in their arrangements, have attended almost en- 

 tirely to external organization. 2ndly. Internal organization has only 

 been partially attended to : the alimentary canal, on which much stress 

 is placed, cannot be considered as a criterion of an animal or a vege- 

 table feeder, and is ill-adapted for the classification of insects. Srdly. 

 No uniform principle of arrangement has been entirely carried out : 

 all have been interfered with by the introduction of other principles of 

 secondary and minor importance. 4thly. It is only from increased 

 attention to the Nervous System that we can expect a more natural 

 system than what exists at present. — The author illustrated his posi- 

 tions by extensive tables of genera. 



On the Noxious Insects which have this year (1838) seriously injured 

 the Apple Trees and Hops. By the Rev. F. W. Hope, F.R.S. 



Mr. Hope described the Aphides as unusually destructive to various 

 species of plants. An insect named Tipula Tritici has appeared in 

 great abundance in some parts of the counties of Hereford, Worcester, 

 Gloucester, and Salop. From an examination of various samples of 

 Avheat submitted to Mr. Hope, it appears that the damage done by the 

 Tipula is less than in previous years. 



Mr. Wailes and Mr. Charles Adamson exhibited the two sexes of the 

 rare insect Psalidogiiathus Friendii, found in the interior of a decayed 

 palm tree in South America. 



On a neio Species of Goliathus and some Lucani,from the Coast of 



Africa. By J. A. Turner. 

 The goliathus belongs, it was stated, to the genus constituted by the 

 Rev. F. W. Hope, under the title of Dicronorhina. Some other la- 

 mellicorn beetles were exhibited, especially t\vo splendid Lucani, all 

 from Southern Africa. 



On the Gemmiferotis Bodies and Vermiform Filaments of Actinia. 

 By T. P. Teale. 



The author stated, that as great differences of opinion existed amongst 

 zoologists as to the nature of the gemmiform bodies and vermiform 

 appendages of Actiniae, he had undertaken their investigation. Some 

 general remarks on the structure of Actiniae were premised, the author 

 pointing out, by means of a large diagram, the various directions of the 

 muscular septa, some lining the cavity and supporting the stomach of
