ionidae falls away and I am still on the search 

 for possible ancestors for m_v Papilionides. 

 And this leads me to believe that photo- 

 graphic methods are probably the only reli- 

 able ones for reproducing neuration, and 

 that my efforts for the introduction of photo- 

 graphy in the illustration of lepidoptera, 

 commenced first more than twenty years 

 ago, as recently kindly remembered by Mr. 

 Moffat in the pages of the Canadian Ento- 

 mologist, were efforts bringing fruit. Let 

 me flatter m_yself also that my efforts to 

 vitalize the study of the wings of the butter- 

 flies will not have been in vain, nay, more, 

 that they may even be ultimately crowned by 

 the restoration of Papilio.

HAYWARD ON BEMBIDIUM. 



In the Transactions of the American en- 

 tomological society, vol. 24, p. 32-143 (Feb.- 

 May, 1S97), Mr. Roland Hayward publishes 

 a valuable monograph on the species of 

 Bembidium of America, north of Mexico. 

 One hundred and twenty-four species are 

 recognized as valid, twenty-four are de- 

 scribed as new, and two new names are pro- 



posed for preoccupied names. The original 

 descriptions of thirteen species described by 

 Chaudoir, Mannerheim, and Motschulsky, 

 as yet unidentified, are reprinted in an 

 appendi.x. In 1S57, Dr. Leconte found 

 Duval's grouping of the European species of 

 Bembidium not at all applicable to the 

 species of our fauna, and published (Proc. 

 acad. nat. sci. Phila., p. 2-5) a catalogue of 

 the species found in the United States and 

 contiguous northern regions, together with a 

 tabular separation of the species into groups. 

 Leconte's keen perception of the true affin- 

 ities of species, evident in all his work, is 

 well shown here, as Mr. Ha3'wai"d, after a 

 thorough study of a large amount of mate- 

 rial, proposes but a slight modification of 

 Leconte's order of arrangement of the groups, 

 suppresses one of his groups, and erects but 

 a single new one. Mr. Hayward's analytical 

 tables are well prepared, and, though useful, 

 should be relied upon only in connection 

 with the descriptions ; each species is fully 

 described. The synonymy is carefully woi-ked 

 out, in most cases by direct comparison with 

 the types; an adequate bibliography is given, 

 and the habitat of each species is noted in 

 more detail than usual in works relating to 

 our fauna.
