NO. 1375. TINEID MOTHS FROM BRITISH COLUMBIA— RUSCK. 747 



between veins 6 and 7, coming out from the cell close below 7; this 

 vein is in every respect as distinct and perfect, tul)ular as the other 

 veins. The left wings of the same specimen and those of the other 

 specimens examined have normal venation. 



Only once before have I come across a similar irregularity in the 

 venation of micros among the more than two thousand wings of which 

 I have made a denuded slidemount. That is in one of Chambers's own 

 specimens of Jiuplacranu.'^ fmcofasciella, in which the left forewing 

 has 13 distinct tubular veins. These two cases must be regarded as 

 monstrosities. The venation in the microlepidoptera is generally 

 remarkably constant within the species witli a few striking exceptions 

 as in some species of 3fonojn.'<, which exhi))it considerable variation 

 within the species, and sometimes in the same specimen. 



Another species unsta])le in venation is Semioscojns demkellncriana 

 Schiffermiiller, which according to ]Meyrick« has veins 2 and 3 in fore- 

 wing stalked. These veins are sometimes stalked, sometimes connate, 

 and sometimes separate. In one European specimen in the U. S. 

 National Museum they are stalked in the one wing and separate in the 

 other. 



HEMEROPHILA KINCAIDIELLA, new species. 



Antennffi dark fuscous, without any color annulations. Labial palpi 

 dark shining fuscous; base of terminal joint and inner side of both 

 joints whitish. Head and thorax mouse-gray, face slighth' lighter. 

 Fore wings dirty bluish white, with dark bluish brown and black mark- 

 ings and with a metallic violet sheen; base of costa blackish; outside 

 of this basal dark patch is a nearly immacidate Avhite costal space, 

 followed a little before the middle of the wing by a In-own costal spot, 

 sometimes dissolved into two or three smaller spots and downwardly 

 continued into a broad, outwardly oblique dark brown transverse streak 

 reaching to the fold. At apical third is a large, dark brown, cloudy 

 costal spot, connected more or less distinctly with tiie dark transverse 

 streak. Just below the tirst dark costal spot in the middle of the cell 

 is a small, round, prominent black dot, and below this on the fold is a 

 similar black dot. Another of the same color and form is found at the 

 end of the cell. The apical and dorsal part of the wnng is irregularly 

 sprinkled with small brown spots. Hind wings, light fuscous; 

 abdomen, yellowish; legs, silver}^ white. Expanse, 17-20 nun.
