246 THE CANADIAN ENTOMOLOGIST. 



pi. 5, is evidently from a very ]ioor negative and therefore of little value. 

 But the rounded bend of the t. a. line (just traceable), the well-developed 

 spot, and the general smoky-suffused appearance, leave me in no doubt 

 about my having the species correctly named. In addition to which I 

 have specimens named by Prof. Smith himself. I have not been able to 

 procure venosa for comparison, and the very small number I have sue. 

 ceeded in obtaining from correspondents, though I have been trying for 

 eighteen months, causes me to suppose that neither discolor nor punctirena 

 are by any means generally common, though they seem to have the same 

 range. I much regret that I have had finally to write this article with so 

 little outside material for study. 



375. Orthosia verberaia, Smith., (Can. Ent. XXXVI, 153, June, 

 1904). — Described from two pairs from here. Of these, the type is at 

 Rutger's College, and a pair are co-types in my own collection. Only ten 

 or a dozen specimens have been taken altogether; one in 1904, the rest 

 during 1903. Sept. nth to 27th; treacle. Under the description the 

 form is stated to be allied to /emtgtnoides, but no comparison is made. 

 Of bicolorago and its var. ferruginoides. I have a good series from the 

 Eastern Slates, and two $ $ and a ? from Cartwright, Man., where I 

 understand from Mr. Heath it is not uncommon. The more usual form is 

 of an orange or rusty, that is a ferruginous, yellow, varying in lint in dif- 

 ferent specimens, with basal, t. a., and t. p. lines, central shade, and sub- 

 terminal area purplish, though in the palest specimens the purple shadings 

 are very slight. This, Dr. Dyar tells me, is the so-called vsivxtiy /err ughi- 

 oides. Typical bicolorago is a less common form, with a purplish shading 

 over the entire outer portion of the wings, both primaries and secondaries, 

 beyond the central shade, making an obvious colour contrast with the 

 inner portion, which probably suggested its name. I have at least one 

 specimen intermediate between the two forms. Of the three Cartwright 

 specimens, the two $ ^ are var. ferruginoides and the $ bicolorago, and 

 their place is obviously with the eastern form. Verberata is luteous or 

 buff rather than yellow, though a few specimens have a more decided 

 ferruginous tint than any of my ferruginoides, and whilst purplish trans- 

 verse lines and shadings seem always present, I have as yet seen no 

 approach to the bicolorago form in the Calgary species. The secondaries 

 are uniformly dark smoky below the subcostal vein, but the costa is pale 

 and contrasts strongly, which is rarely the case with my bicolorago, in 

 which the secondaries are, as a rule, much paler. The t. a. line seems
