minute salamander, with its legs distended on the honey. 
Experiments were also tried with the primitive larva of the 
blister-beetle (Cantharis vesicatoria), which could not be 
induced to feed on the eggs of Vespa or Polistes, nor on 
simple honey, beyond a few feeble attempts ; but eventually 
they accepted the 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 larve proved equally successful. 
These primitive larvae 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, woerein they hastily buried them- 
selves, for the supposed purpose of completing their trans- 
formations, but contrary, as it would seem, to their accustomed 
habits. Here they appear to have perished, being no longer 
discoverable; their death being attributed 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. 
Spiders in the Bark of T’rees.—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 Rey. 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 situ; whereas, according to a fuller 
description of the nests submitted to Mr, Pickard Cambridge,
