voiy slioit; the ungues are strongly toothed. Our species have been divided into three 
genera, which have, however, been reunited by Lacordaire into a single genus, dis¬ 
tinguished by having the antenna) received in grooves.

The species of this genus form several very distinct groups, which I Siould consider as^ 'l 4 Ct; ’ 1 
genera, but that Lacordaire states that they merge imperceptibly together. Those found 
in our territories may be thus arranged.

entirely white, and the tip of the abdomen more finely pectinate: the body is perhaps a 
little less attenuated behind, and more rounded.
