a Family of Coleopterous Insects. 661 
internal margin of the clava of the antenne exhibits a stronger 
contraction at the base than in that species, and the incision on 
its outer edge is much wider, and the basal tooth very acute. 
(Tasg. nostr. Fig. 50.) If ultimately found distinct, the species 
may receive the name of acutidens. 
I provisionally place in this genus the two following insects, 
not having had an opportunity of minutely examining their 
trophi: their general flattened appearance and the apparent in- 
dication of a rudimental notch at the base of the clava of their 
antenne approach the true Platyrhopali; whilst in some respects 
they agree with some of the Paussi, such as P.affinis, $c. I 
obtained a knowledge of them, as well as of the Paussus excavatus 
and P.armatus, during my visit to Paris in September 1830, 
subsequent to the reading of the commencement of this paper.
