MEMOIR OF LATREILLE. 27 
into his place of confinement, and upon making 
inquiry he was informed by the prisoner that the 
insect was very rare, and that he was desirous of 
sending it to two young naturalists then residing in 
Bordeaux. His wishes were complied with, and 
the insect was transmitted to MM. Dargelas and 
Bory de Saint- Vincent. Latreille's eminence as an 
entomologist happened to be previously known to 
tliese individuals, and they immediately exerted 
tliemselves in his favour, and that with such suc- 
cess, that he was ultimately released. He has grate- 
fully commemorated this singular incident in more 
than one of his works. A figure of the insect is 
engi-aved on his tomb ; and most of the entomo- 
logists of France preserve, in a conspicuous part of 
their cabinets, the Necrobie-Latreille, in grati- 
tude for the service it rendered to their master. 
Nay, the more sentimental of them, feeling even 
this to be an inadequate indication of the emotion 
of their hearts, have an inscription attached to it, 
intimating that they asked and obtained from the 
hands of their honoured master, the specimen ex- 
tibise slender, without spines : tarsi four-jointed, the joints di- 
lated and membranous at the apex ; the unguicular one long 
and slender. 
The species ruficollis is oblong ovate, covered with long liairs, 
shining : eyes and antennae black : head blue-green, punc- 
tured: thorax somewhat quadrate, vrith. the sides rounded, 
rufous, punctate : elytra rufous at the base, the rest greenish- 
blue, with eight punctured striae on each, the interstices finely 
shagreened ; thorax beneath and breast rufous, abdomen black ; 
legs rufous.
