unlikely for a wasp grub, protected in its cell in tlie nest as 

 it is, to receive such an injury. It rather more strongly 

 suggests a congenital defect in the closing of the umbilical 

 opening. It is not easy to say whether the want of symmetry 

 in the peccant segment supports this view or the contrary. 

 I will hand the specimen to the British Museum." 



A VERY RARE BRITISH BEETLE. — Mr. 0. E. Janson ex- 

 hibited a fine example of Tapinotus sellatus, Fab., taken by 

 him on June 9th last near Horning, Norfolk, and recorded in 

 the October number of the Ent. Mo. Mag. Only two British 

 specimens were previously known, these having been taken 

 in the years 1838 and 1846. He also showed some other 

 Coleoptera of interest taken in the same locality, 



A British specimen of Notodonta bicoloria. — Mr. 0. E. 

 Janson also exhibited on behalf of Mr. L. H. Bonaparte- 

 Wyse, who was present as a visitor, a fine male specimen of 

 Notodonta bicoloria, Schiff., taken by him near Killarney on 

 June 7th last, and recorded in the " Irish Naturalist " for 

 October. 



Living Dermestid Larvae. — Mr. Green exhibited living 

 larvae of a Dermestid beetle, Tiresias serra, found under dead 

 bark of an oak tree, in the neighbourhood of Shrewsbury. 

 The larvae have the abdominal segments clothed with erect 

 rufous hair. There is also a loose caudal tuft of long greyish 

 hairs, which is vibrated rapidly when the insect is annoyed 

 or disturbed. 



Mr. Main and Mr. Donisthorpe commented, the latter 

 observing that judging from his experience of the larva in 

 observation ants' nests, the vibration had apparently a 

 protective value. 



Mr. Green also read the following note on the oviposition 

 of the sawfly Pteronus sertifer. 



" The method of oviposition of the sawfly Pteronus sertifer 

 has been a subject of discussion at several of our meetings 

 during the present year. Insects raised in captivity, by 

 Mr. Morice and myself, have refused to throw any light on 

 the question. I have now been successful in obtaining eggs 

 from a wild female. The parent was captured on the 1st of 

 this month, and confined in a glass tube with a sprig of pine
