Lepidocyrtus eobustus, sp. n. 



Segmentum ahdominale quartum, thoracem, et segmentum 

 ahdominale primuvi longitudine cequans. Unguicuhcs superior' 

 dentibus duobus jmrvis armattos ; unguicidus inferior lanceolatus, 

 inermis. Long. 3'6 mm. 



Antennae. — Three times longer than the head, the joints related 

 to one another in length as 2 : 3 : 3 : 4.

 26 : 2 : 1. The fourth abdominal segment six times the length of

This species is closely allied to L. maximus Schott *, from the 

 Kamerun. It is separable, however, on account of the great 

 size of the fourth abdominal segment ; in the inferior claws of 

 the feet being lanceola.te, with its lower margin curved instead of 

 being straight ; and in the stouter tenent hair.
