PHYTOPHAGA FROM SUMATRA 459 



fusion can in my opinion arise since everyone knows wliether 

 in a description, tlic Animal or A'egetable kin<i:(lom is meant 

 and changes of names once familiar, do not add to the assistance 

 of the memory, which in Entomology is ah^eady more than too 

 heavily taxed. The other genera created by Weise are princi- 

 pally founded on male structural charactc^rs which vary almost 

 with every species so that about another fifty or more genera 

 might easily be made ; Weiso has moreover taken no notice of 

 Italy's papers on the genus Aidacophora (Journ. Linn. Soc. Y. XX, 

 1880 and 1888) where most of the species are characterised 

 and tabulated in a useful way and which must have the priority 

 in regard to specific names. 



lOf). Pseudocophora sumatrana, n. sp. — Belovy black, above 

 flavous as well as the anterior legs, sulcus of thorax straight, 

 elytra strongly and semi-regularly punctured. 



-t^. Elytra with a basal fovea, the latter bidentate, anteriorly, 

 last abdominal segment trilobate, its median lol)e nearly flat. 



Length 3 lines. 



Head impimctate, flavous, frontal tubercles narrowly trans- 

 verse, clypeus with an acute ridge, palpi incrassate, antennae 

 only extending to the base of the elytra, pale flavous, the 'third 

 joint as long as the first and longer than the following joints, 

 thorax twice as broad as long, the sides straight at the base, 

 rather strongly rounded anteriorly, the surface entirely impunc- 

 tate, the basal sulcus straight and deep, elytra strongly punc- 

 tured in closely approached very irregular rows, their epipleurae 

 continued to the apex , undersides and the four posterior legs 

 black , claws bifid. 



Hab. Si-Rambé. 



From P. hrunnea, Baly and P. nilem^ All. the present species 

 is at once distinguished by the black underside and similar co- 

 loured posterior legs, it resembles in this coloration several true 

 species of Aidacophora from which it can readily be separated 

 by the prolonged ely trai epipleurae , the female has , as usual 

 simple elytra and entire last abdominal segment. 



107. Phyllobrotica elegantula, n. sp. — Flavous, the antennae
