species to be the 4ranea venatoria of Linnzus, and to belong to the 
genus Actinopus, Pty. (Sphodros, Wlck.) instead of Mygale and 
Cteniza, to which it has been referred, a very detailed description is 
given of a new species congenerous with the last-mentioned insect, 
of which living specimens had been forwarded to the Society from 
Barbary by Edward A. Drummond Hay, Esq., Her Majesty’s consul- 
general at Tangiers, with the following characters. 
Actinopus eedificatorius, W.  Piceo-niger nitidissimus, corpore 
subtus pilisque mazxillarum pallidioribus ; abdomine obscuro fusco- 
sericeo, subtus ad basin maculis 4 luteis ; cephalo-thorace supra 
et postice semicirculariter valde impresso, pedibus longitudine fere 
equalibus. Long. corp. lin. 14. Inhabits Barbaria. Mr. Drum-

Observations on the structural characters of the Death-watch, with 
the description of a new British genus belonging to the family of 
Psocide. By J. O. Westwood, F.L.S. 
After noticing the inaccuracies into which several recent authors 
have fallen relative to the structure of the Death-watch, a new Bri- 
tish genus is characterized as follows : 
Croruitta, W. Corpus apterum. Caput subtriangulare. Antenne 
longa, articulis circiter 27. Prothorax brevis. Pedes simplices, 
tarsis 3-articulatis. 
Clothilla studiosa,W. Luteo-albida, oculis brunneis, antennis fuscis, 
labro albido, incisuris abdominis brunneis, pedibus albidis. Long. 
corp. lin. 1. Inhabits the interior of houses. 
February 3rd.—The Rev. F. W. Hope, President, in the Chair. 
Mr. Westwood exhibited some original drawings of Crustacea 
made by Mr. Wallcot of Bristol, also various larve forwarded to 
him by Mr. Wallcot, jun., including one which that gentleman had 
no hesitation in considering as that of Platyrhinus latirostris, which, 
however, closely resembled the larva of a Leptura. 
He also exhibited drawings of a minute white Acarus, found on the 
backs of books placed against a damp wall, and also of the larva and 
pupa of a species of Latridius found in the same situation, and of an 
exceedingly minute 6-footed Acarus (visible only with a lens of high 
power) found amongst the hairs of the body of the last-mentioned 
larva. : 
Mr. S. Stevens exhibited a beautiful moth of large size from the 
interior of Africa, having the appearance of the genus Erebus, but 
with short palpi and shortly bipectinated antenne, belonging to the 
family Bombycide (Saturnia Isis, Westw. MSS., of which a figure 
and description will shortly appear in the ‘ Naturalist’s Library’). 
Mr. Hope exhibited a Scolopendra from New South Wales, in 
which one of the two hind feet was very much smaller than the 
other, and which was supposed to have resulted from the reproduc- 
tion of the limb. 
The conclusion of Mr. Westwood’s memoir on Trap-door Spiders 
was read,
