Zanzibar by Dr. Kirk. He also exhibited a portion of a stem which had 

 been bored into by the larva, and which was especially remarkable on 

 account of the presence of a series of holes nearly equidistant, and bored 

 in a direction perpendicular to the main gallery. These holes, which 

 opened a communication between the inner gallery and the outer air, were 

 of a conical shape, the inner opening being the widest, and Mr. M'Lachlan 

 suggested that they were made by the insect for the purpose of ventilating 

 the gallery. 



Mr. Smith remarked that he had bred numbers of a Longicorn beetle 

 [Saperda pojmlnea), and had frequently observed in the shoots of the aspen, 

 in which the insect undergoes its transformations, similar small holes, 

 which in this case are made by a parasitic Hymeuopterous insect. 



Mr. W. C. Boyd exhibited a specimen of Pterophorus iMus, taken at 

 Deal in June, 1869. He stated that the specimen agreed very closely with 

 the continental P. Icetus, as does another specimen taken at the same place 

 by Mr. Purday in 1877, but that it differed from the species taken in 

 Norfolk by Lord Walsingham (two specimens of which were exhibited for 

 comparison), which had been returned by Prof. Zeller as being " probably 



P. IcEtUS." 



Papers read. 



The Secretary read a paper, communicated by the Ptev. T. A, Marshall, 

 entitled " Notes on the Entomology of the Windward Islands," in which 

 the author gave a list of the species which he had captured in Barbadoes, 

 Martinique, and Antigua since June, 1877, together with remarks on habits, 

 and descriptions of new species. 



The Rev. H. S. Gorham communicated " Descriptions of new Species of 

 CleridcB, with Notes on the Genera and Corrections of Synonymy." 



Dr. D. Sharp communicated a paper " On some NitidulidcB from the 

 Hawaiian Islands." 



The Secretary read a paper, by Mr. J. P. Mansel ^Veale, entitled " Notes 

 on South African Insects," and exhibited drawings made by the author in 

 illustration. The paper related to insects found on Acacia horrida, and 

 protected by resemblances to various parts of that tree ; species resembling 

 birds' excrements, and also some remarkable cases of mimicry of ants by 

 spiders of the genus Salticus, were likewise referred to. 



Mr. Wood-Mason exhibited and made remarks upon the insects referred 

 to in the foregoing paper, and supplied the names of the MantidtB and 

 Phasmida. He also suggested that the resemblance of a Mantis to bird- 

 droppings might be of use to the insect for purely aggressive purposes, since 

 flies were known to be attracted by such droppings. In conclusion, Mr. 

 Wood-Mason mentioned a case of mimicry of ants by spiders which he had 

 observed in India.
