The primaries in alboveiiosa are whitish with smoky lines ; in phragmitidi- 

 cola the ground color is a straw yellow, darker on costa, through the centre 

 of the wing and just below the apex ; the median vein is white, and in 

 fact all the veins can be distinctly traced as fine white lines. At the end 

 of the discal cell, almost on the median vein, there is a distinct black 

 5pot, and there is an oblique row of dark spots — often not very distinct — 

 from the apex to the hinder margin. I have in one instance received a 

 specimen of Z. Harveyi Grt. as albovoiosa^ and several times Harveyi have 

 reached me ticketed phragmitidicola. L. Harveyi is smaller, has the 

 ground color of primaries paler, and while the pattern of markings is 

 almost identical with phragmUidicola, it is readily distinguished from it by 

 the much heavier, clearly defined dark markings, by having several distinct 

 black dots in the discal cell, and by the want of wliite scales on the veins j 

 the median vein is the only white one, and this is much more distinct than 

 in phragmitidicola ; the secondaries seem also much darker in Harveyi. 



As to relative position in the family, Arsi/onche stands near the head, 

 before Acronyc/a, while Ltucania (or Heliophila according to Mr. Grote) 

 comes after the typical Nocfua and nearer to Orthosia and its allies. 



Mr. Grote, in his Catalogue, places Arsilonche just before Leiccania, 

 but it seems much nearer to Acronycfa, and I consider the place Lederer 

 gave the genus when he described it as more appropriate. 



NOTES ON A GALL MTFE OF THE NETTLE TREE 



( Celtis occide7italis. ) 



BY REV. T. VV. FYLES, COWANSVILLE, P. Q. 



Gall, formed on the under side of the leaf, pear-shaped, half an inch 

 long, forms a cup-like indentation on the upper surface. I have counted 

 eighteen galls on one leaf. One mite in a gall. 



Mite, one-tenth of an inch long. Eyes large and protuberant, light 

 red. Antennae moniliform, ten-jointed — the basal joint and that next it 

 being much larger than the rest. Proboscis for suction. Four undeveloped 

 wings — mere protuberances in the case of some (probably younger) speci- 

 mens — generally translucent, but in some instances smoky brown. Legs, 

 six in number, hairy, semi-transparent. Abdomen much enlarged, top-
