together, fourth joint rugose, setose, clavate at tip, truncate and 

 slightly sinuate outwardly ; prothorax hardly longer than the head, 

 transverse ; elytra very minutely shagreened and punctulate, a little 

 broader than long, apical margin straight and simple, external 

 angles long, setose, sutural stria entire, triplicate at base ; abdomen 

 longer than the elytra and a little broader at base, first dorsal 

 segment very much excavated transversely at base, the excavation 

 carinate on each side and fasciculate, lateral margin broader at base 

 and slightly incised externally, narrowed at tip ; second segment 

 conspicuous, transverse, and having a minute tubercle on each side 

 of the base, third segment longer than the others, apex elongate and 

 curving upwards ; legs of moderate size, simple, somewhat elongate 

 and setose. Female. Length 2*50 mm. 



This species is a very singular one. The only example known is 

 a female, and the darker patch of the apical part of the abdomen, 

 mentioned by Mr. Peringuey in his description, is caused by the 

 dried-up ovaries which are seen through the transparency of the 

 teguments ; a case occurring often in all light-coloured Pselaphida. 

 I presume that the recurved protuberance of the last dorsal 

 abdominal segment is also a characteristic of the female.

 mucronate, sixth much smaller than the fourth and transverse,
