mens by Tieffenbach, and sent me by the late Prof. Hopffer. The species 

 is a little smaller than illcda (= magdalena Strecker) and may be easily 

 recognised by its pale greenish-gray, mossy primaries, with the lines dusky 

 and rather diftuse. The hind wings are light yellow with the median band 

 straight, terminating before the margin with a short, rather abrupt curve. 

 The terminal band is abbreviate, narrow, scalloped on its outer edge over 

 the median nervules. There is a small black spot on the margin before 

 anal angle. The species is- very distinct and can be mistaken for no 

 other. 



Catocala abbreviatdla Grote. 



I have this species from Illinois, taken by Mr. Bean. The t. a. line is 

 straight, outwardly oblique to below median vein, when it becomes 

 obsolete. It is not black shaded as in Whitneyi, which I have from the 

 same locality. The three species, nuptialis {= myrrha Strecker), abbre- 

 viatella and Whitneyi, form a series of allied forms, but can be sufficiently 

 and readily distinguished. 



Catocala graciiis Edw. 



The form described by Mr. Edwards has the primaries light gray, the 

 lines broken and the internal margin more or less shaded with blackish. 

 The species recalls the concluding arnica group in the colors, bluish gray 

 primaries and bright hind wings, and I have put it last in the series on 

 this account. I am not certain now what Mr. Edwards' similis is. In 

 Mrs. Bridgham's collection is (or rather, was) a specimen labelled similis 

 by Mr. Edwards, which belonged to what I consider as a variety of 

 gracilis, having the primaries mixed bluish gray, rather dark and somewhat 

 hoary. The lines are distinct, or usually so, and the basal dash of gracilis 

 is wanting. This last seems the only important character, but it is present 

 in var. basalis of habilis and wanting in the type. Thife dark form (which 

 seems also a little shorter winged) has been taken with the type by 

 myself near Buffalo, and by Dr. Bailey near Albany. I have seen it also 

 from Pennsylvania. In the collection of the Ent. Soc. of Phil, there is a 

 specimen labelled similis, which in my " Revision" I have referred to as 

 belonging to this variety of gracilis. But Mr. Edwards' description will 

 not agree in this that he says : " beyond is a ferruginous band followed by 

 a gray line which is dilated on the costa so as to make a triangular apical 

 spot.'' This and the size will not correspond, and it is probable that Mr,
