BURR— ORTHOPTERA, DERMAPTERA 127 



Small, black ; head and thorax reddish ; the whole body finely punctulate. 



Head smooth, tumid, globose ; eyes small, anterior. 



Antennas with 10 segments; first not strongly clubbed; third and fourth about 

 equally long, conical ; the rest longer and stouter, all conical. 



Pronotum slightly longer than broad, parallel-sided, the sides reflexed, with a distinct 

 median suture and an impression on each side of the pi'ozona. 



Mesonotum ample, with a distinct, but not very sharp keel which dies out before 

 reaching the posterior margin. 



Legs long and slender ; the femora blackish, passing to yellowish at the knees ; the 

 slender tibiae compressed ; tarsi yellowish. 



Abdomen narrow at the base and gently dilated to about the sixth segment and then 

 gently narrowed again ; lateral tubercles on the fourth segment distinct. 



Last dorsal segment transverse, short with a faint median sulcus. 



Forceps with the branches remote, cylindrical, tapering, feebly arcuate. 



$ unknown. 



This species is more nearly related to Nannisolabis willeyi Burr, and D. philetas 

 Burr, from Ceylon, than to Metisolabis malgacha Burr, from Madagascar, which has large 

 and lateral eyes. The keel, however, of the mesonotum, though neither long nor sharp, 

 is quite distinct, so we cannot place the species in Nannisolabis. The presence of this 

 keel, at the same time as the normally situated small eyes make it necessary for us 

 to place it in the genus Brachylabis, which should be retained for the typical Chilian 

 species, B. clhilcnsis Blanch. This arrangement is unnatural, and must be regarded as 

 provisional, for the system will probably be modified considerably when more material has 

 been accumulated and more species known of this curious and interesting group. 



I take pleasure in dedicating this species to Mr Hugh Scott.
