GEOGRAPHICAL DISTRIBUTION OF LIMEMTIS WELL ILLUSTRATED. 

 In the Geographical and Geological Exhibition now being held at 

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

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

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

 tertlies Lmienitis <"'f//cntis and L. ursula in relation to their inter- 

 mediate form L. prowpiiia. On the map of the United States and 

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

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

 shading, and the area occupied by L nrsida 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 ot the map. Where L- proserpina has been found is 

 indicated by green shading 1 lines at right angles to the other shad- 

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

 of Limenitis, grading from L. arthemis through L. proserpina to 

 I,, ui-siiia. 



At the other si;le of the map, which is entitled "A Study in 

 Geographical Distribution." hangs a sheet with brief explanation 

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

 Mr Scudder's opinion that L. />i-ose/-/x'/i<> is a hybrid form of L. 

 art/tern** and L. ni'xiila, and Mr. Edward'; rc.isons for the view 

 thnt L . i>i-<>*ci-/>/n(t is a variety of L. arthemis. Miss Dimmock ha.- 

 not only indicate;! the distribution of the species as given in Scud- 

 der's " Butterflies of the Eastern United States," puoli-ln'il in isss. 

 but has carefully compiled, from the various entomological period- 

 icals, later recorded rupture*, so that her map i> a graphic pi-r-i-ii- 

 tationof the liybrid-variety (|iiLstion in regard to I. . /n-<>s< r/'n<i, 

 brought down to 18!)!). It is unneces-ary to add that tlii- map 

 not a part of its author'- -.-hool \vork in natural science.
