THE CANADIAN ENTOMOLOGIST. 415 



N. B. — I. The "Zoological Record" and "Bericht der Entorn." incor- 

 rectly cite the source of Zehntner's pa[)ers, giving only the "separate" pagina- 

 tion and source. There are in Java numerous experiment stations, with 

 entomological staff, etc. ; the results of their researches, entomological, 

 chemical, agricultural, are mostly published in the " Archief voor de 

 Java-Suikerindustrie," a periodical now in its 13th year, but which 

 apparently finds its way to very few American or European libraries. 

 The entomological contributions, however, are distributed by their authors, 

 separately paged and as " contributions " to their particular experiment 

 station, the plates being unnumbered or with the numbers of the original 

 impress. For instance. Aphis adusta was described (on p.?) of the 5th 

 vol. of the "Archief" (1897) and reissued separately paged in the 

 '' Mededeelingen van het Proefstation Oostjava, niewe serie No. 37." It 

 is these latter references that are quoted in the " Record" and " Bericht." 



I am a little uncertain of the exact dates of Koch's genera. The 

 " Bericht" states, heft 1-4 (1854)3 5-7 (1855); 8-9 (1856); the rest 1857. 

 Heft 8 began p. 237, but I am not quite certain where heft 9 finished.

 Aphidina?, etc.
