honey-bag of the hive-bee as an available substitute for their 
ordinary food, affixing themselves to this and thriving thereon. 
In one instance also a compound of honey and young Polistes 
larvee proved equally successful. 
These primitive larve are of a brownish black colour, with the 
second and third thoracical and the first abdominal segments 
more or less pallid, having the usual long caudal sete and 
triunguiculate tarsal claws. After the lapse of nine days they 
changed to the secondary form as aforesaid. Three of these 
attained the third stage, having still well-developed legs (pattes 
assez bien conformées), but with no indication of eyes, coinciding 
in this respect with those of Meloé and Sitaris.* After a time, 
becoming restless as adults, they were placed upon some earth, 
wherein they hastily buried themselves, for the supposed purpose 
of completing their transformations, but contrary, as it would 
seem, to their accustomed habits. Here they appear to have 
perished, being no longer discoverable; their death being attri- 
buted to insufficient moisture. 
From the localities frequented by this Cantharis, where the 
burrows of Halicti also abound, M. Lichtenstein considers it 
probable that the larve of the former are reared in the cells of 
these bees; but, in such case, they could not quit those abodes to 
undergo their ultimate metamorphoses in the earth. 
Our attention has been called to a new trap-door spider from 
South Africa, which forms its nest in the bark of trees, recently 
described and figured by the Rev. O. P. Cambridge in the ‘ Annals 
and Magazine of Natural History’ (November), under the name 
of Moggridgea Dyeri. 
The nests, however, figured by Mr. Pickard Cambridge, differ 
essentially from two which were exhibited at the July meeting of 
this Society ; these being wholly imbedded in the solid bark, and 
having a hinged lid closely resembling the surrounding parts of 
the cuticle itself, as if retained in sitd@; whereas, according to a 
Las 
fuller description of the nests submitted to Mr. Pickard Cam- 
bridge—published in the ‘ Field’ newspaper of the 28th August— 
they were stated to “consist of a silken tube, scarcely more than 
an inch in length, rugged on the outside in such parts as may be
