At ray arrival in Buitenzorg, at the end of April 1909, the dry season just commenced and this being the less favourable period for insect-collecting, I obtained but few specimens. Later on I perceived that this country is much poorer in regard to these groups than Europe, so that my collections only increased from time to time with some spare examples. Panorpata and Planipennia are very rare here, much rarer than in Europe, and they were found nowhere abundant, so that their economic importance is still more insignificant and their appearance in the tropics proportionally much rarer.
