Descriptive Catalogue of the Coleoptera of South Africa. 41 
Two cosmopolitan species of this genus have been met with in 
South Africa. They belong to the second section of the genus 
characterised by the tempora rather elongated behind the eyes, and 
the deep lateral constriction of the thorax.

LATHRIDIUS (CONINOMUS) CONSTRICTUS, Gyll. 
Elongate, little convex, more or less brownish testaceous, shining ; 
antenne and legs lighter; antennal club two-jointed; thorax as long 
as wide or a little longer, the two median longitudinal costae more or 
less distinctly raised, sides deeply constricted behind the middle ; 
elytra punctato-striate with the alterning intervals more or less 
distinctly costiform, and without any transverse interruption or 
tubercle. Length 1:5-1:'8 mm. (2 mm. in South Africa). 
The two examples I have seen differ from the European types in 
being a little longer, almost 2 mm., and by the tempora, which are 
quadrate and parallel instead of being convergent from behind.
