Hampshire irregularly, falls between Manchester and Concord. This last-named 

 butterfly, a variety resulting from the meeting of the Banded Purple of the Cana- 

 dian province with the Spotted Purple of the Alleghanian, is restricted in its range 

 to a narrow strip which, entering New Hampshire from the vicinity of Norway, 

 Me., bends southward and again northward, passing diagonally across Vermont, 

 skirting the great lakes, crossing Michigan, and disappearing somewhere in the 

 British possessions westward. Scudder, making his map about 1873, located ^^'^^ 

 band with Concord about in the middle, but there is reason to believe that, as de- 

 termined by the range of Basilarchia astyanax-arthemis, it should be brought 

 somewhat southward. There cannot, of course, be any line determined with in- 

 flexibility and mathematical exactitude, but careful study through a long series of 

 years — such study as is practicable under the auspices of the Institute — cannot 

 fail to place the boundaries of the two great provinces with approximate precision. 

 Observations, carefully made and faithfully recorded during the next decade, rel- 

 ative to Basilarchia astyanax-arthemis, Gryllotalpa borealis, CEcanthus niveus, 

 Thyreonotus dorsalis, Diapheromera femorata. Labia minuta and Termes flavi- 

 pes will aid materially in the prosecution of this interesting inquiry. 



Writing in 1873, Prof. Scudder said : " Probably no State in the Union pre- 

 sents so striking a variety in its animal life as New Hampshire ; " and with refer- 

 ence to the determination of the boundary between the Canadian and Alleghanian 

 fauna he added : " The local zoologists of New Hampshire can render science an 

 important service by a careful record of such facts in as many distinct localities 

 as possible." In attempting to carry out this suggestion the Manchester Institute 

 of Arts and Sciences has undertaken a work which, if faithfully performed, will in 

 future years redound to its credit. 



One individual of Cicada septendecem was found near the Bald Hill road by 

 Mr. Herbert E. Richardson, in June, 1899. Presumably it was one of a limited 

 number composing a sort of advance guard to a more formidable host in 1900. 

 The Seventeen-year Locust was found in considerable numbers about Manches- 

 ter in 1883, and there is probably a distinct brood in this section, although it ap- 

 pears not to have attracted the attention of hemipterists. Marlett, in his compre- 

 hensive monograph of Cicada septendecem, makes no reference to this New 

 Hampshire 1883-1900 brood. 



Packard, in his "Guide," conveys the inference that Massachusetts is practi- 

 cally the limit of the range of the Ant-Lion northward. He says : " Myrmeleon 

 obsoletus Say is not rare in the warmer parts of the country, and has been found 

 at Salem, Mass., by Dr. E. P. Colby. M. abdominalis Say has -also been found as 

 far north as Milton, Mass., by Mr. J. Schofield." M. abdominalis is quite abund- 

 ant about Manchester. The larvae are found in the ledges at Rattlesnake Hill in 

 Auburn, and beneath an over-hanging bank on an island in the Merrimack river, 

 immediately below Amoskeag Falls. Specimens of these larvae were reared to 

 adults by Mr. George E. Burnham, in 1898 and 1899, and also by Mr. Edward H. 

 Fogg in the latter year. 



Say's description holds remarkably, the principal variations being in the mark- 

 ings of the feet and the tips of the antenpae ; and even here the variations are
