whitish, cylindrical, tbirteen-jointed, coleopterous larva, six millimetres in 

 length, had dropped from one of these excrescences. 



" Turning over the plates of Chapuis et Candeze's ' Catalogue des larves 

 des Coleopteres,' I met with its counterpart on plate vii., fig. 5, copied as 

 being that of Anaspis maculata, Fourc, from a paper by Perris in the ' Ann. 

 de la Soc. Ent. de France,' t. v. 2me Ser., 1847, pi. 1. Not having at 

 that moment the ' Annales ' to refer to, and the ' Catalogue ' only affording 

 the reference 2^ur et simjde, I jotted down a description and then left the 

 larva alone. Six days later it had turned to a sculptured pupa four milli- 

 metres in length, of a dirty white colour, with the head bent forward on the 

 chest, extremely short semi-detached wing-cases, and a pointed hind-body, 

 from which the cast larval skin was dangling. Breathed upon once it 

 manifested its sense of the annoyance by a series of vigorous tail-lashings 

 to and fro. It then appeared that its hind-body was fringed with detached 

 white silky bristles, and that a few such were also scattered over the other 

 parts of its body. On the morning of the 17th of March I found the empty 

 pupa-skin shrivelled up, and at a short distance the beetle crouching against 

 the rim of the glass in the characteristic sneaking fashion of the Mordellonse. 

 It proved to be Anaspis maculata, Fourc, as expected. Having since 

 referred to Perris 's paper, I find he has given such ample details of the larval 

 state that I deem it useless to reproduce my description, as it tallies in 

 every particular. Perris mentions that the larvae, pupae and imagines are 

 found in France in irregular worm-eaten galleries of dead shoots of the wild 

 and cultivated grape vine. At this season of the year the insect, as is 

 well known, is common on all sorts of shrubs and herbs in blossom, particu- 

 larly on thorns, and it is very likely that the female deposits her eggs 

 indifferently in all sorts of ligneous plants." 



Mr. Butler read " Translations of descriptions of certain Pericopides 

 omitted in a list of species recently read before this Society." 



Mr. M'Lachlan read a paper " On the external sexual apparatus of the 

 male of the genus Acentropus," supplementing the memoir on the genus by 

 Mr. Dunning, read at the meeting on the 4th of March. He detailed the 

 structure of this apparatus as observed under a f -inch objective, with the 

 compound microscope, and exhibited drawings illustrating his remarks. 

 After cursorily alluding to the question of the ordinal position of the genus, 

 and observing that those entomologists who doubted its Lepidopterous 

 nature could not have studied the structure of the insect, or else maintained 

 an affected opposition, he entered into the subject with regard to the pre- 

 sumed existence of more than one species, and stated that, although minute 

 differences existed in the genital organs of individuals from various parts of 

 England and the Continent, he saw nothing to convince him of the multi- 

 plicity of species some entomologists admit. Nevertheless he reserved an
