Three specimens in the Museum collection (2 gg and 
_ 1 &) from Bone, Algeria, differ from typical form by their 
very small dimensions, all other characters being in com- 
plete accordance with specimens from other localities. 
I think that they represent a distinct geographical race, 
though the specimens from Biskra (not very far from Bone) 
are of the usual dimensions. Still, the difference is so 
striking that I believe it to be useful to give the dimensions 
of this small form, while I hope that further investigations 
of Algerian specimens will make clear its taxonomic 
position. The male type has the following dimensions : 
Length of body 16 mm.; of pronotum 3 mm.; of elytra 
13 mm.; of hind femora 10 mm. The dimensions of the 
female cotype are: Length of body 27 mm.; of pronotum 
4-5 mm.; of elytra 21 mm.; of hind femora 15 mm.

one female cotypes).
