Mr. Jeuner Weir exhibited a specimen of Lycrena Icarus, which had a 

 hollow horn-like protuberance, fixed in front of the head, exactly between 

 the antennae. He was disposed to think the adherent object was the theca 

 of a moss from which the operculum had fallen off and the spores had

 in the county of Southampton. 



Mr. Weir also exhibited specimens of the harvest-bug (L^;;<ws autumnalis) 

 in the si.x-legged larval state, and detailed the excessive irritation they had 

 produced by their attacks on himself. Probably in consequence of the dry 

 summer, they had been unusually numerous; he had counted eighty pustules 

 caused by the Acarus in one of his feet, and as they extended over the front 

 of his body as high as the arms, he calculated he could not have had less than 

 four hundred pustules at one time ; they did not attack the back or the arms : 

 he found that sponging the body with vinegar allayed the irritation and pre- 

 vented the attacks, but the application of the remedy caused the wounds 

 produced to smart very much. He found them most plentiful amongst 

 leguminous plants, as sanfoin, red clover and French beans. He could 

 plainly perceive the pest running rapidly over his boots whenever he went 

 amongst the plants mentioned. The larger specimens were red in colour, 

 but the ncwly-hatchcd young were whitish.
