 Kieff. nicht zu unterscheiden und auch C/i.pliimosus L. (nach Johannsen) äußerst 

 ähnlich sind. J. C. H. de Meijere (Hilversum).

Die Blütenstände von Thalictrum aquilegifolium zeigten sich von der Larve einer 

 Fliege, Phytomyza, besetzt. Sie fliegt im April etwa 14 Tage lang, und die Entwicklungs- 

 zeit dauert etwa einen Monat. In über 100 Blüten wurde je nur eine einzige Larve be- 

 obachtet. Der Dipterologe Escher- Kündig glaubt, daß die auffallende Glätte der Puppe 

 ermögliche, bei geringstem Druck des abdorrenden Kelches zwischen seinen Blättern 

 durchzugleiten und auf den Boden zu fallen. K. Bretscher (Zürich).

 Journ. Variation, Bd. XXIV, Heft 3, S. 7-2—73, 1912. 



The author briefly records certain of his observations on: (a) conspicuous species 

 of Lepidoptera being attacked by birds, while an abundant but inconspicuous species 

 appears to escape such attacks : (b) capture of a specimen of Melanitis ismene inter- 

 mediate between the wet- and dry-season forms in a wet district of Sumatra, with re- 

 marks on the fact that in some very wet parts of Sumatra both the seasonal forms 

 occur indiscriminately all the year round: (c) resting-habit of Papilio memnon and Teli- 

 cada nyseus etc. H. Scott (Cambridge).

 in Support of the mimicry theories, supplied by a small collection 

 of Bornean butterflies. In: Ent. Mo. Mag., ßd. XXIII, Heft 4, S. 79—84, 

 1912. 



The author emphasises the fact that the collection which he discusses was 

 made by a non-entomologist, who had no tendency to search for particular 

 species, but collected all those butterflies which were most conspicuous and easy 

 to capture. He states that the collection presents several features which support 

 the theories of mimicry. The chief of these features are as follows: (1) the large 

 Proportion of Danaini and Euploeini, which together number 126 out of the 

 whole 274 specimens comprising the collection: this provides "evidence in sup- 

 port of the Müllerian theory of mimicry, which postulates associations or com- 

 binations of distasteful butterflies characterised by a common conspicuous war- 

 ning pattern, which is further displayed and emphasised by large numbers of 

 individuals and by a fearless, slow method of flight, so that they fall an easy 

 prey to the net", (2) Papilio caunus mendax was taken together with its model 

 Euploea diochtianus lowei. (3) The modeis are numerically superior to the mimics; 

 e. g., there are about 20 examples of P. caunus mendax in the collection to one 

 of E. dioddianiis loivei. (4J The conspicuous absence of $$ tends to show that 

 this sex is better protected (by resemblance to surroundings, more perfect mi- 

 micry of distasteful model, etc.), and hence less liable to be captured, than the cT.
