are very suggestive of the genus Nala, but the lobed second tarsal segment at 

 once excludes thern from the family Labidurida?: in F. bait lea the dilation is very 

 feeble, as may be seen from the figure, but it is enough to forbid the inclusion of the 

 species in the Labiduridae. 



The specimens are all in Baltic amber, which is commonly attributed to the Lower 

 Oligocene age.

Size medium, general colour brownish black, very dark. 



Antennas with 12 segments, black ; the first rather long and thick; second minute; 

 third long and cylindrical ; fourth half as long as third and a little thicker, somewhat 

 thicker at the apex than at the base ; fifth about as long as third, cylindrical ; sixth and 

 the rest as long as third or a little longer, almost cylindrical. 



Head smooth, black. 



Pronotum as broad as the head and as long as broad ; anterior margin convex. The 

 sides and posterior margin straight, with the angles rounded and covered with short 

 sharp bristles. 



Traces of a minute scutellum apparently discernible in one specimen. 



Elytra well develoj>ed, black, covered with short sharp bristles, well rounded at the 

 shoulders, truncate posteriorly. A sharp keel seems to run from the shoulder to the 

 apex. 



Wings well developed, of the same structure and colour as the elytra. 



Legs black ; femora rather thick, especially the anterior pair. 



Tibiae slender ; tarsi slender, first and third segments equally long ; second cylindrical, 

 feebly dilated, short, but still longer than broad ; ungues typical ; no pulvillus discernible. 



Abdomen parallel, black, no pliciform tubercles discernible, sparsely covered with dark 

 tubercles and thickly pubescent except on the pale and smooth posterior borders to the 

 segments. 



Last dorsal segment ( 6 ) transverse, rectangular, not tubercular. 



Pygidium ( d ) short and very transverse, with a short point in the middle. 



Porceps remote at base, cylindrical, rather strong, rapidly tapering, regularly arcuate, 

 with a sharp tooth near the middle on the inner margin.
