Superficies subloevis, nitida, setis minutissimis sparse munita. 



Oculi magni, angulos anticos capitis utrinque occupantes ; ocelli numerosi, densissime 

 congregati, numero plus quam viginti. 



Antennae fere tres quartas partes corporis longitudine sequantes ; scapi articulus 2 

 paulo longior et crassior quam articulus 3 ; articulus 4 plus duplo longior quam articulus 

 3, articulus 5 quarta parte longior quam articulus 4. Flagellum paulo longius quam 

 articulus 5 scapi, articulus 1 longior quam articuli 2 et 3 subsequales simul sumpti. 



Maxillse prioris paris lamina exterior dentlbus 4 (secundo ceteris multo minore) + 6 

 (omnibus apice fissis, subsequalibus). 



Frons ante non marginata. Epistoma linea transversa in medio leviter procurva. 



Trunci segmenta 1, 2 margine posteriore curvato, segmenta 3, 4 margine posteriore 

 subrecto, segmenta 5, 6 leviter segmentum 7 profunde in medio incurva ; anguli postici 

 segmentorum 1 — 4 rotundate obtusi, segmentorum 5 — 6 subrecti, segmenti 7 rotundate 

 truncati. Segmentum 2 pronoto quarta parte dorsi vix longiore, segre discreto, utrinque 

 angulos priores laterales segmenti occupante. 



Cauda trunco abrupte angustior ; omnia segmenta, prsesertim segmenta 4 et 5 

 magna. 



Telsum triangulum, lateribus leviter incurvis, post late rotundatum. 



Uropodiun scapus multo longior quam latior, latere exteriore profunde canaliculato ; 

 processus endopoditi non brevior quam scapus ; exopoditum duplo longius quam scapus ; 

 endopoditum gracile, paulo longius quam scapus. 



Color fuscus, in medio trunco maculis et striis oblongis crebratus ; segmenta trunci 

 macula laterali rotunda albida, etiam anguli postici segmentorum perlucente albidi. 



Long. 8 mm. Lat. 3 "5 mm. 



Distribution. Seychelles Archipelago : many specimens of this species were 

 obtained during the Sealark expedition: Montague Alphonse, Cascade, 1800 feet; summit 

 Mt. Sebert ; Silhouette. In the Mu.seum at Hamburg are pi-eserved specimens taken by 

 Dr A. Brauer in Malie, 2 — 8 May, 1901. It had already been taken in the year 1892 

 by M. Ch. AUuaud at Mahe, Marianne and Praslin ; DoUfus refen-ed it wrongly to 

 Philoscia mina Budde-Lund. I have seen the original specimens in the Museum at Paris.

Superficies laevis, nitidissima. 



Oculi mediocres, angulos anticos capitis utrinque occupantes ; ocelli minuti, sub- 

 confluentes. 



Antennae duas corporis partes longitudine subaequantes ; scapi articulus 2 non 

 longior quam articulus 3, articulus 4 fere duplo longior quam articulus 3, articulus 5 

 quarta parte longior quam articulus 4. Flagellum scapi articulo 5 longitudine aequale. 



Maxillte prioris paris lamina exterior dentibus 4 (dens primus posterior longissinius, 

 2 longus, 3 et 4 parvi) + 6 (dens 1 longus, 5 parvus, ceteri mediocres, omnes acuti, 

 integri).
