Erotylldae, EndomycWdae and Coccinellidae 



of Sumatra 



by AI. S. Ciorltani. 



The f()ll(j^\iiii;- is au account of Ihe Erotylldae, Endomy- 

 chidae and Coccinellidae colk-etod by Dr. H. Duhrn in Sumatra, 

 chiefly at Soekaranda in 1894, aud now in Uie Stettin Museum^ 

 I have addcd the deseriptiou of two or ilirec from Borneo, and 

 of one or two from Ceylon, Mhich m ere necessary to illustrale 

 ihe new genus Triplacidea. 



Fain. Erotylidae. 



Subfani. Laiiguriides. 



The Languriides contained in this colleetion as regards 

 some species are numerous in examplcs, and by means of them 

 I have been able to assign many of the speeies described by 

 Harold and Crotch to their geuera. At tlie time of writing 

 I have also, in my hands the colleetion made by Croteh, noA\' 

 the property of Cambridge University; The large eoUections of 

 Eastern Languriides, made by Beccari, E. Modigliani, D. Lans- 

 berg, Lorin and others in Sumatra, Java. New-Guinea, the Island 

 of Mentawei, and other parts, belonging to the Royal Museum 

 at Genoa; together with many of Baron von Harold's types 

 also the property of that Museum, M-hich have b}- the kindhess 

 of Dr. R. Oestro been placed in my hands for determination. 

 These latter have enabled me to collate typical examples, and 

 clear points in synonymy whicli would not have been possible 

 otherwise. The genera proposed by me may seem in some 

 cases founded on trivial characters; but as divisions they will 

 be found necessary for the elucidation of species Avhich are 

 extremely alike. Very little usc hath hitherto been made of the 

 coarseness or fineness of the faeettes of the eycs. It is however
