| Taxonomic list comments: "Unfortunately, the black marl, in which the Swiss insects included, are very much weathered pyrite and despite the careful storage so that the valuable Heers types, which are all available in the Zurich Museum, Will in a short time be lost to science. Many pieces have already been defaced, and it is therefore entirely dependent on inadequate Heers figures." Handlirsch, 1906 | |
