 14 are dipterous specimens, 6 seen by me. The 20 specimens are from 

 14 difTerent localities, and besides those, Dr. Brauer, Xeuropteren

NORTH AMERICAN SPECIMENS. 



Dr. Packard in Proc. Boston S.N.H., 1870, t. 13, p. 407, mention- 

 ed the capture of a dipterous specimen of Psectra diptera in Brunswick, 

 Maine, Sept, 16th. When Dr. Packard showed it to me, I recognized 

 directly my old European acquaintance, though my collection was still 

 in Europe. Dr. Packard notes that the specimen agrees perfectly well 

 with Mr. M'Lachlan's description and perfectly wellx with his figure, 

 though the abdomen is blunt and rounded. The type is perhaps de- 

 stroyed, at least up to the present I can not find it among the insects of 

 the Salem Academy. 



1 am responsible for the locality Siberia given by Dr. Packard: it 

 should have been S. Russia. 



The second specimen, collected near Detroit, Michigan, May 25, 

 1874, by Mr. H. G. Hubbard is dipterous; the abdomen in bad con- 

 dition. 



The third specimen was collected in the J31ue Hills, near Boston, 

 Mass., June 1875, by the late Mr. Morrison. It has well developed hind 

 wings; abdomen wanting. Both are in my collection. 



When 1 was able last spring to acquire the types of the late Asa 

 Fitch, I was much surprised to find that his H. Jelicalulus, Report I, 1885. 

 J), 96, is a specimen o^ Psectra diptera with well developed hind wings. It 

 was swept from the grass of Prairies in Illinois, October i, (A. F.). The 

 specimen was covered with mould, but could be cleaned so as to be per- 

 fectly recognizable; the abdomen is in bad condition. 



The identification with the European species has been made with 

 care. There is only one difference. The hind wing of the female from 

 Konigsberg has the sector beginning from the first bifurcation blackish 

 to the margin, as described by Mr. Wallengren; the female from Boston 

 not, except that the small furcations on the apical margin are brownish. 

 The type of A. Fitch has the hind wings rolled together with the ab- 

 domen, but the sector though somewhat darker than in the female from 

 Boston is not blackish. The female from Russia is in very unlucky 

 position, but as far as I can see the sector is not blackish. The material 

 before me does not allow me to go farther. Concerning the genital parts 

 I can decidedly affirm, that the two dipterous specimens from Konigs- 

 berg are males. The specimen from Russia shows a ditTerently pointed 

 end of the abdomen.
