Genus 1.—Paralabidura, n. g. 
Cum genere Labidura congruet ; differt statura minore et graci- 
liori, tarsis brevioribus, posticis pronotum longitudine baud vel vix 
superantibus, segmentis primo et tertio subaequantibus. 
Differs only from Labidura in the smaller size and slender build, 
and shorter tarsi, the posterior pair scarcely, or not at all, exceeding 
the pronotum in length, the first and third segments approximately 
equally long, and the third segment slightly exceeding the first. 
This genus is raised for the reception of the small, dark 
slender species, hitherto included in Labidura. 
In all known species the colour is dark chestnut. 
The posterior tarsi are of different lengths in the dif¬ 
ferent species, but in no case does the posterior pair 
exceed the length of the pronotum, and first, second and 
third segments are either equal, or the third a little 
longer than the first ; in Labidura and Forcipuki the first 
segment is the longest. 
The type of the genus is Paralabidura lividipcs, Duf.
