DESCEIPTIONS OP NEW GENERA AND SPECIES OF 

 PHYTOPHAGOUS COLEOPTERA 



OBTAINED BY ^^'. DUHEKTY IN THE MALAYAN ARCHIPELAGO. 



Bv MAPvTIN JACOBY, F.E.S. 



THE collection of Fhytophaga, submitted to me by the Hon. Walter Rothschild 

 for examination, and contained in that gentleman's museum, was made by Mr. 

 Doberty, partly in the already explored greater islands of the JIalayan Archi- 

 pelago, and partly in those smaller and nearly unknown islands in which, as might 

 have been expected, many new species would be found. Although Mr. Doherty .states 

 that Phytophaga were found to be comparatively scarce in the islands lying south of 

 those which have been explored by ]Mr. ^\'allace, it is probable that this is only the 

 case during certain periods of the year, and that amongst the small species a rich 

 harvest may yet be expected by a resident collector. As it is, more than a hundred 

 new species are here described. Besides these, a few others from Queensland, Burmali, 

 etc., have been added, which were obtained at other times by Mr. Doherty and certain 

 other collectors.
