Mr. G. Lewis on 



have 1378 names. In the Berlin Catalogue of last year for 

 2420 sj)ecies of Histeridse there are 2940 names. 



Mr. F. Muir has been several years (1907-1910) in Eastern 

 Asia seeking for creatures that eheek the ravages of the 

 sugar-cane weevil, Sphenophorus , and he discovered that 

 Plcesius javanus, Er., fed, both in the larval and adult stages, 

 on species of this genus, and that in Amboina and Cei*am 

 Platylister abruptus, Er., fed mostly on the larvse of a 

 ^phenophurus uhich infests the sago-palms. Mr. Muir 

 consequently imported into the Hawaiian Islands the two 

 Histerids, liberating at Honolulu about 50 specimens of the 

 Plasius and 250 of the Platylister, in the hope that they 

 may prey on the weevil \yhich is injurious to the sugar-cane 

 there. The Plcesius has not been seen since its liberation, 

 but the Platylister has been found twice. Sphenophorus 

 occurs in Asia as far north as South Japan, and lately a 

 species of Platylister has been found in Kiusliiu and Formosa 

 and another in South China. Neither of these districts 

 has yet yielded the Plcesius. It is not probable chat the 

 Histerids feed solely on these particular weevils, but the 

 vegetation wliich attracts the one atibrds at the same time 

 convenient shelter to the other when not actively engaged in 

 seeking for food. 



As regards the Histeridoe generally, no adequate collection 

 of the species has yet been made, and their systematic classi- 

 fication, as far as a satisfactory lineal arrangement of the 

 genera can be effected, has not been reached.
