Seychelles and Rangoon. 3 



endemic forests; one [Arthrolips insuJce-Jongre)^ as Rtate<i 

 above, only on a cultivated islet. Of the remainder, Dauhania 

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

 elevations, while the two most abundant forms (Sericoderifs 

 and Leioisium) seemed generally distributed from the culti- 

 vated country up into the endemic woods at high altitudes. 



Most of 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 tlie 

 Lewisium were swept from long grass, and most of the 

 Sucium pt'caultianum were beaten from dead palm-leaves, a 

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

 Lewisiiim were fonnd in R fallen brancli containing an ante's 

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

 dental or intentional I cannot say. 



AJJiniti'et. — The world-fauna of creatures so minute as 

 Cor3-lo[)hidae must be at present but very imperfectly known, 

 therefore it is not profitable to discuss at length the atfinities 

 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 minutissimus, Matth., hitherto recorded from 

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

 allied to Oh'garthrum, known only from S, America, and to 

 Corylophus, widely distributed in Europe and Asia. Meio- 

 derus was previously* recorded only from Japan, Lewisium 

 from (Jeylon and Japan. The other genera are known from 

 all parts of the world. 



The Coiylophid fauna of Madagascar appears to be very 

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

 des Iiisectes Coldopteres de la Region Malgache ' * (p, 105) 

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

 tion, seems quite unlike any of the Seychelles forms. 

 JMatthews describes his Sacium bifasciatuni (Mon, p. 54) 

 from Madagascar, and this is a little like my Sdcium p/caidti- 

 anum. I have found no fuither records of Corylophidse 



* VoL xxi. of Grandidier's 'Histcare Physique, Naturelle, et Politique
