geringe Temperaturunterschiede, je nach Umständen die Grundform oder eine 

 der beiden Varietäten hervorbringend, während bei anderen Arten einzelne Formen 

 auffallend fest sind, die Raupen von Leucania comma L. wurden an Badylis glo- 

 merata und Deschampsia caespitosa lebend gefunden. K. Bretscher (Zürich).

 Mimetic Butterflies of the Ethiopian Nymphaline genus Pseuda- 

 craea. In: Nature. Vol. 90, Nr. 2237, S. 36—37, 1912. 



Jordan, from a study of the genitalia, suggested that Pseudacraea curytus 

 from W. Africa, P. hohleyi, P. terra and P. ohscura from Uganda, P. royersi from 

 Mombasa and P. Imitator from Natal, each of which mimics a district species of 

 Planema, are really all forms of one species. Of these forms, P. hohleyi is sexu- 

 ally dimorphic, mimicking the sexually dimorphic Planema macarista; the others 

 are sexually monomorphic, as are their Planema modeis. Further evidence in the 

 same direction is derived from intermediate forms, from female Jiohleyi with the 

 male colouration, and from the fact that the male of one form has been seen 

 pursuing the female of another. The intermediates are found especially on an 

 Island in Victoria Nyanza, on which the Planema modeis are uncommon. Finally, 

 Prof. Poulton now reports that Carpenter has bred the terra form from a 

 female ohscura which had some resemblance to hohleyi. It appears therefere that 

 all these supposed species of Pseudacraea are Polymorphie forms of one species.

Pupae of Danais chrysippus and Hypoümnas misippus were exposed to heat 

 and cold. In each case the effect was to cause Variation towards forms occurring 

 in nature (var. dorippus of chrysippus, and var. inaria of misippus) which are 

 regarded by the author as nearer the ancestral type.
