ANTHRIBIDAE FROM THE ISLANDS OF ENGANO , 



MENTAWEI AND SUMATRA, 



COLLECTED BY DR. E. MODIGLIANI.

The collection of Anthribidae from the Islands of Engano, 

 Mentawei and Sumatra , submitted to me by Dr. R. Gestro, is 

 of special interest in two respects. Firstly the collection shows 

 that the number of existing species of Anthribidae must be very 

 great in comparison with what we know hitherto of them. 

 Though I have described from Perak, Sumatra, Borneo and Java 

 a good number of species during the last two years and have 

 seen nearly all the types of the species described from the islands 

 of the Malay Archipelago, the greater proportion of the species 

 of the present collection is new to me. To give an instance, how 

 the number of species of Anthribidae will increase , when the 

 coleopterous fauna of the tropics becomes more exhaustively 

 known, it will suffice to say that out of the 10 species of the 

 genera Apatenia and Nessiara of the present collection only one 

 is known to me. Unfortunately there are a vast number of new 

 species represented in the collection only by single specimens, 

 which, for several reasons, I can not now describe. 



The second point which this collection demonstrates most 

 obviously is, that the species of Anthribidae vary markedly ac- 

 cording to locality. It is not improbable that, when our knowledge 

 of these insects will have become a little more complete, many 

 of the forms which I treat at present as distinct species will 

 turn out to be geographical forms of one species. 



It will be noticed that in the following pages, when referring 

 to the name of an already described species, 1 do not put the
