Porro, and Latrinus, Walk., and the various observations made upon it 

 by Messrs. Curtis, Aube and Guerin-Meneville, the author shows its 

 affinity to Latridius and Mycetcea, alluding especially to the remark- 

 able circumstance, that some of the species possess nine joints to the 

 antennae, another ten, and another eleven. Whereupon Mr. J. F. 

 Stephens stated, that he had taken species of this genus on the wing 

 at Hertford, Camberwell and South Lambeth. 



" Notes on the supposed Sense of Pain in Insects." By Mr. C. 

 Boreham ; of which the following is an abstract. On pinning two 

 moths (one through both the thorax and abdomen) in the daytime, 

 they remained immoveable until their usual time of flight in the 

 evening; whilst a peacock-butterfly pinned just before sunset was 

 found early next morning as perfect as when left, and on removing 

 the pin it flew away. Some beetles on being pinned at first remained 

 for a short time inanimate, and then struggled violently as if endea- 

 vouring to escape from confinement : a specimen merely confined by 

 a brace across the body performed the same motions. From three 

 specimens of the common house-fly, engaged in cleaning their fore- 

 feet, he cut off one of the hind-legs, whereupon two of the insects 

 continued the action without any signs of inconvenience, as did also 

 the third, after moving a few inches. 



Mr. C. Lamb stated that he had observed, that Coleoptera when 

 stuck with a pin which is subsequently removed die shortly after- 

 wards ; but the President stated, that he had observed that the 

 species of Colymbetes possess the power of repairing the injury done 

 to the elytra by piercing them. 



June 2nd. — The Rev. F. W. Hope, President, in the Chair. 



Mr. Weir exhibited a fine specimen of the male of Dorthesia Cha- 

 racias, remarkable for the long white filamentous tuft at the extre- 

 mity of the body. 



Mr. S. Stevens exhibited living specimens of Rhynchites cupreus 

 from Black Park, Bucks, and also from the north of England, taken on 

 the flowers of the mountain ash, in company with Molorchus minor. 



Mr. Douglas exhibited an apparently new species of Orthotania, 

 recently taken amongst heath at West Wyckham. 



Captain Parry exhibited a box of Coleoptera from China and the 

 Himalayas, including several fine Lucani, and a new species of Tri- 

 ctenotoma*. 



The Rev. F. W. Hope brought under the notice of the meeting 

 the destruction caused by white ants and other insects to the wooden 

 sleepers used in the railroads in India, and reference to the kyanizing 

 process having been made, Mr. J. F. Stephens stated, that on one 

 occasion he had taken a number of specimens of Thanasimus unifas-
