Seychelles and Rangoon. 3 



eiulemic forests; one {Arthrollps i»suIce-Ioi>r/iv), as stated 

 above, only on a cultivate J islet. 0£ the remaiiuler, Dauhania 

 (gen, nov.) occurred in the high forests and at more moderate 

 elevations, while the two most abundant forms (Sericoderiis 

 and Lewisium) seemed generally distributed from the culti- 

 vated country up into the endemic woods at high altitudes. 



]\Iostof the material was collected somewhat promiscuously, 

 by general sweeping and beating of vegetation, but in some 

 cases I have exact records of the manner in which specimens 

 were taken. Thus some of the Sericoderus and of the 

 Lewisium were swept from long grass, and most of the 

 Sacium pi'caultianum were beaten from dead palm-leaves, a 

 very fruitful source of beetle-life. Two individuals of the 

 Lewisium were found in a fallen branch containing an ant^s 

 nest (see p. 24), though whether their presence was acci- 

 dental or intentional I cannot say. 



Affinitie'i. — The world-fauna of creatures so minute as 

 Corylophidae mu-it be at present but very imperfectly known, 

 therefore it is not profitable to discuss at length the affinities 

 of the Seychelles series. Moreover, having regard to the 

 highly peculiar nature of the endemic vegetation, and to the 

 large number of peculiar insects and other animals existing 

 there, it is probable that some at least of the species herein 

 described will prove to be absolutely confined to these islands. 

 But such indications of affinities as exist may be briefly con- 

 sidered for what they are worth. 



The only form referred to a previously described species 

 is Orthoperus mimitissimus, Matth., hitherto recorded from 

 S. America and W. Indies. The new genus Dauhania is 

 allied to Ohgarthrum, known only from S. America, and to 

 Conjhphus, widely distributed in Europe and Asia. Meio- 

 derus was previously recorded only from Japan, Lewisium 

 from (Ceylon and Japan. The other gentra are kuouni from 

 all parts of the world. 



The Corylophid fauna of Madagascar appears to be very 

 little known. The only species included in Alluaud's ' Liste 

 des Insectes Coleopt^res de la Ke^ion Malgache ' * (p. lOo) 

 is Sacium monatrosum (Schaufuss) f, which, from its descrip- 

 tion, seems quite unlike any of the Seychelles form?. 

 ^Matthews describes his Sacium hifasciatum (Mon. p. iJX) 

 from Madagascar, and this is a little like my Sacium picaulti- 

 anum. I have found no further records of Corylophidoe
