Geographical distribution of limenitis well illustrated.— 

 In the Geoofraphical and Geoloorical Exiiibition now being held at 

 the new Science Museum Building in Springfield. Mass , is a curi- 

 ous map. the work of Miss Anna Dimmock, a grrammar school girl 

 of that city. This map illustrites the distribution of the two but- 

 terriies Limenitis arthemis and L. ursula in relation to their inter- 

 mediate form L. pro>ierpiaa. On the mip of the United States and 

 British North America, which is perhaps 10x18 inches in size, the 

 area from which A. arthemis is known is indicated by oblique blue 

 shading, and the area occupied by L ursula by yellow shading in 

 the same direction. Where both species occur the yellow lines in- 

 terlace with the blue ones, thus giving a mild greenish shade to 

 that portion of the map. Where L- proserpiaa has been found is 

 indicated by green shadinar lines at right angles to the other shad- 

 ing-lines. At one side of the map hangsa box with four specimens 

 of L^//^e^^i7/■«, grading from L. arthemis through L. proserpina to 

 L. Ursula. 



At the other side of the map, which is entitled **A Study ia 

 Geographical Distribution." hangs a sheet with brief explanation 

 of the facts concerning these butterflies, and a short statement of 

 Mr ScxiAder's opinion tha,t L. proserpina is a hybrid form of L. 

 arthemis and L. ursula, and Mr. Edward's reasons for the view 

 that L. proserpina is a variety of L. arthemis- Miss Diivunock has 

 not only indicated the disti'ibutiou of the species as given in Scud- 

 der's " Butterflies of the Eastern United States," published in 1888, 

 but has carefully compiled, from the various entomological period- 

 icals, later recorded captures, so that her map is a graphic presen- 

 tation of the hybrid-variety question in regard to L. proserpina^ 

 brought down to 1899. It is unnecessary to add that this map was 

 not a part of its author's school work in natural science.
