The genus Camptotoma (Reiche), introduced by Lacordaire into the 
group, is unknown to me, and can scarcely, according to the characters 
given, belong to the Lachnophorine. Stigmaphorus (Motschulsky), is 
founded on species of Lachnophorus, without any differential character 
of the slightest value. Ewcerus and Eudalia are here incorporated for 
the first time with this sub-family. 
The great majority of the genera and species belong to the tropical 
and warm parts of America, from the Rio de la Plata to California. 
Lasiocera is peculiar to tropical and sub-tropical Africa and Asia; Lu- 
dalia occurs only in the hotter parts of Australia. 
The Lachnophorine are insects below the medium size of the Cara- 
bide. In facies they (Lachnophorus, Lasiocera, Chalybe), resemble 
Bembidiine of the genus Zachypus, or (Eudalia, Amphithasus, Anchono-
