THE CANADIAN ENTOMOLOGIST. S67 



260 has often been recorded. A Calgary specimen of my own I com- 

 pared with his male type of rena there, but did not feel quite sure that 

 they were the same. Whether cerv'uiea = vena in part or not, is, to my 

 mind, a doubtful point, and I think the types of rena may prove a 

 mixture. Cervinea is certainly allied to munis, as Prof. Smith states, the 

 latter being a larger species, with black or blackish in the cell. The type 

 of munis is from Colorado, a female, in the British Museum. 



Just what dissona is I cannot quite discover. It was described from 

 Labrador, and the type is presumably in Mo^chler's collection. A 

 Labrador specimen in the British Museum from the Grote collection is 

 well figured by Hampson, and might pass for a poorly-marked rena or 

 cervinea. The dissona of Prof. Smith's collection did not help me, and a 

 Labrador female standing under the name in the Strecker collection 

 seemed to me some species not closely allied to rena at all. Staudinger 

 gives it priority over opipara Morr., which he makes a variety, but in this 

 Sir George Hampson does not concur. 



261. E declarata Walk., syn. decolor Morr. and caf?ipestris Grt. 

 ( - insnlsa Smith, nee. Grt.). — This is the species which has long stood in 

 nearly all North American collections, and has been treated of in literature 

 as insnlsa Walk. But I have endeavoured to demonstrate above (under 

 256) that instilsa is distinct, and not very closely allied, Declarata, of 

 which the type is a female in the British Museum from Vancouver Island, 

 is wrongly treated by Hampson as a synonym of tessellata. It is the 

 species figured by Holland on Plate XXIII, fig. 3, as insnlsa — erroneous- 

 ly, as per other authors — and also fig. 10, as oc/irogaster, though how it came 

 to pass muster as the latter species is a mystery. Cainpestris Grt., type a 

 female in the same collection from New York, is the same species. The 

 type of Morrison's decolor I have not seen, nor the description, and merely 

 follow Prof. Smith and others in referring it as a form oi declarata with 

 contrasting shades, not uncommon in the species. Such a form is figured 

 by Hampson, though the figure seemed to me too contrasting for any 

 specimen in the Museum collection. If the same, declarata has prefer- 

 ence by nine years. 



Expulsa Walk., type a female in the British Museum, from Vancou- 

 ver Island, has been referred by Prof. Smith to insnlsa, and by Sir George 

 Hampson to messoria. I wholly agree with the latter. I had already in my 

 collection a good series of jnessoria from Vancouver Island, where a dark 

 variation is rather common, and recognized it at once.. It is a rather uni- 

 form and dark specimen with even smoky secondaries, and dark shading
