23(3 THE CANADIAN ENTOMOLOGIST. 



Argyrophyes Grote (Bull. B. S. N. S., i, Plate v.) 



The enlarged figures of the neuration (3, 2) I have given are incorrect 

 and may mislead. I have made a fresh preparation of the wings accord- 

 ing to Mr. Dimmock's method, The primaries are like Zeller's figure of 

 Nola confusalis (fig. 43, a) except that the base of 6 is opposite 5 from 

 the cross vein, as I have figured it. My diagnosis is correct except that 

 for "9 from upper and outer angle of the cell to costa" it should read 

 "just before the upper, etc.,^' and here my figure and description, which 

 agree, are both wrong. Also 7 touches the costa just before the apex, 

 not at apex. The hind wings differ from Zeller's fig. h, and agree with 

 mine in that vein 4 is joined at right angles by a true vein to vein 3, and 

 is nearer 3 than 6, as I have drawn it. My vein 4 is probably vein 5 of 

 Heineman (i, 273). There is also one accessory internal vein on hind 

 wino-s. I have referred the single species to the Geometridcz, but it should 

 be evidently placed near Roeselia among the Lithosians. The neuration 

 is so very variable among the European species that it might not be held 

 o-enerically distinct, but vein 5 is not thrown off from the middle of the 

 cross-vein as given by Heineman for Roeselia, but is nearer 3 (4 wanting) 

 than it is 6, and joined by a true transverse vein to the submedian, which 

 is thus 3-branched, not as Zeller figures confusalis, 2-branched with 5 inde- 

 pendent from the middle of the cell without a true connection with the 

 submedian vein itself. I cannot now account for my errors in drawing 

 the enlarged figures of Argyrophyes, except that the wings, which are very 

 frail, were insufficiently ci eared of scales, preventing me from getting an 

 accurate view of the venation. The diagnosis given by me (1. c. 175) 

 should be amended to read as follows : 



Argyrophyes, n. g. 



Ocelli wanting. Maxillae short, concealed by the prominently long, 

 very thickly scaled palpi, which exceed the front, their third article directed 

 forwards. Wings full ; primaries large with evenly arcuate costa, straight 

 external, and consequently long internal margin; lo-veined ; celllong, 

 incompletely closed ; 2 to 5 at decreasing intervals ; 5 from the cross-vein 

 near 4 ; 6 from the cross-vein near 4 and opposite 5 ; between 5 and 6 

 the cell is incompletely closed by an angulated fold; 7 to costa just 

 behind apex; 8 out of 7 to costa; 9 just before the upper and outer 

 angle of the cell to costa; 10 and 11 wanting. Hind wings rounded, 

 7-veined ; cell incompletely closed ; two internal veins counted as one ;
