being that of Anaspis maculata, Mourc., from a paper by Perris in the ‘ Ann. 
de la Soc. Ent. de France,’ t. v. 2me Ser., 1847, pl. 1. Not having at 
that moment the ‘ Annales’ to refer to, and the ‘ Catalogue’ only affording 
the reference pur et simple, 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 Mordellone. 
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 larve, pup 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 3-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 
opinion on the specific value of the great discrepancy in the alar development 
of the females, over which there hung a certain amount of mystery, and on the 
obvious fact that the males, from different localities, also varied in the 
contour of the fore wings.—R. M‘L.
