THE ORIENTAL ANTHBIBIDAE OF THE VAN DE 

 POLL COLLECTION. 



By K. .JORDAN, Ph.D. 



THE famil}' of AnthribitJue of the van de Poll collection which we bought 

 from Messrs. 0. E. .Jauson & Sons comprises a little over three thousand 

 specimens, most of which came from the Oriental Region. The number of species 

 is not large, the smaller forms particularly being bnt poorly represented. But 

 there is some valnable material among them from localities whence few Anthribidae 

 Lave been recorded. The undescribed species and varieties are not abundant in 

 the collection, and many of those which are new were already known to me from 

 other collections. As the specimens add to our knowledge of the distribution and 

 variation of the Anthribidae and allow me to correct some errors, I propose to work 

 out the Oriental forms as time permits and to publish the results, without, however, 

 binding myself to any systematic sequence of the genera. 



1. 



Genera: Mecocerus, Physopterus, Eugigas, Meganthribus and Xenoceras. 



I have attended to tliese genera first for no other reasons than because they 

 contain large species, are well represented in the collection, and their removal from 

 the boxes facilitates the study of the smaller species. The genera dealt with in an 

 article on the van de Poll Anthribidae are not necessarily closely allied. 



Genus Mecocerus Schonh. (1833). 



In both the Catalogue Goleopteronon- of Gemminger and Harold (1872), and 

 tiie (Aitulorjiie des Anthribides by A. Bovie (i'JU.j), Acnidhothorux lonyiiornis 

 Gaede is quoted as being published in ls3",' {May. Zool. vol. ii. t. 15), I.e. prior to 

 iSchOnherr's vol. i., in which apiieared the description of Mecocerus. Fahraeus, 

 however, in iSchiinh. vol. v. p. 183, gives 1833 as the date of publication of Gaede's 

 description, and Laeordaire in his den. Col. vol. vii. p. 490 says iu a footnote that 

 XJecocera.i has several months' i)riorit.y over Acanthothortuc. 



The species of Mecocerus fall into two groups, the frons being snicatc in the
