BUDDE-LUND— TERRESTRIAL ISOPOUA 377 



Ocull uiagiii, semiglobosi ; ocelli numero c. 22 — 23. 



Antennse longissimse ; scapi articuli et flagellum ut in M. maculata. 



Frons ante marginata et utiinque lobata ; lobi laterales longiores et angustiores, 

 subtrianguli, apicibus obtusis, linea marginalis frontalis in medio profundius emarginata, 

 ut media frons bicornis fiat. Epistonia medium triangulis elevatis, superiore et inferiore 

 se in medio attingentibus, convexum. Clypeus magnus, declivis, non lobatus. 



Trunci segmentum 1 sulco anteriore coUari tenui ; margo posterior utrinque pro- 

 fundius incurvus, angulis lateralibus acutissimis, non retroductis ; epimerum infra dente 

 longo, gracili, acuto. Segmentum 2 pronoto magno. Segmenta 2 — 7 margine posteriore 

 utrinque levissime incurvo, angulis lateralibus post sensim acutioribus. 



Caudse segmenta 3, 4 epimeris magnis ; epimera segmenti 5 epimeris precedentibus 

 angustiora, acute triangula, telso paulo breviora, lateribus interioribus subparallelis. 



Telsum triangulmn, ejusdem longitudinis atque latitudinis, lateribus levissime 

 incurvis, apice obtusiore, supra per medium ad longitudinem leviter sulcatum. 



Uropodum exopoditum multo longius quam scapus. 



Color in medio corpore e nigro fuscus, in epimeris trunci caudseque flavus ; antennse 

 flavee vel albidse ; color interdum pulchre purpureus, lateribus anguste albidis. 



Long. 16 mm. Lat. 8 mm. 



Distribution. Seychelles Archipelago : Mahe, one specimen from mountain forest, 

 Nov. 1905 : Silhouette, five specimens. I have also had many specimens for examination, 

 taken the 2 May 1901 by Dr A. Brauer and preserved in the Museum, Hamburg. 



Subfamiha Oniscinse. Budde-Lund (l), p. 75. 



This subfamily contains the largest number of the known forms of terrestrial Isopods. 

 In nearly sixty genera are contained about one thousand species. Authors have produced 

 an abundance of new species on very superficial desci'iptions. These are very often 

 quite incorrectly placed, because the external characters on which the afiiinities are 

 founded are often without any value. 



I have lately in a paper ((7), p. 8) given hints, which should certainly lead to the 

 understanding of the affinities between the numerous genera. By later examinations 

 of the given characters and of other new ones, I have reached so far as to think that 

 I can give a survey of the genera, not only useful for determination but also in the main 

 points in accord with a natural system.
