It is perhaps best described as a dark cloud, partially or wholly 

 filling the space between its indistinct defining lines. I have 

 studied the species closely for years, and entirely failed to 

 recognize two species out of specimens standing variously as 

 catenula and vetusta. As a whole, Western specimens have 

 better defined maculation than those from the East, but I have 

 specimens from Chicago, Calgary and Glenwood Springs which 

 match well. It is the usually better marked Western forms 

 which have been called catcnula in error, and which Smith 

 now designates as catcnuloides. I have seen a good deal of 

 material in other collections, including Prof. Smith's own, but 

 have no reason for supposing that the new name applies to 

 anything but vetusta. Holland's figure of vetusta is correct, 

 and the catenula of my published Alberta list is the same 

 species. 



Catenula is much the same color, but smaller, narrower of 

 wing and much lighter in build. Besides this, the most obvious 

 difference in maculation is in the reniform. This is a blackish 

 constricted crescent, with the cross vein in its center usually 

 showing up of the pale ground color. Contrast this with the 

 broad cloud of vetusta. In catcnula there are three distinct 

 black points on the costa, defining the extremities of basal, 

 t. a. and t. p. lines. In vetusta these points are geminate, in- 

 closing whitish. Though I have never confused the two my- 

 self, the resemblance of occasional specimens is undeniable, 

 especially in the case of a small vetusta in which the dark 

 cloud in the reniform is much reduced. The two species stood 

 mixed in the British Museum when first I saw them, but have 

 since been separated. Fortunately the type of catcnula is cor- 

 rectly figured in Vol. IV, of Hampson's Catalogue, and the 

 figure of contagionis is the same species, as is also, I regret 

 to say, the woodcut under vctusla, the type being too poor to 

 figure. Both have occasionally a pinkish or violaceous va- 

 riety, as has also, by the way, the similarly endowed scandens. 

 Muracnuki Y. & R. I believe to be vetusta. 



As Prof. Smith makes no generic reference for catenula in 

 the paper above referred to, we can only assume that his
