NO. 1376. LEPIDOPTERA OF THE K00r]<:NAl Dl^TRlVT—DYAl:. y85 



uiiik'd, till but two so-called species arc now listed, I tliink there is 

 really )»ut one, with a series of local races, each adapted to it.s special 

 locaUt3\ I would therefore unite tdl the names under stqjtentrwnalU 

 Walker. 



GLUPHISIA LINTNERI Grote, var. SEVERA Hy. Edwards. 



Two specimens, May (Mr. Cockle), May 80. The larva* were later 

 beaten from balsam poplar l)y Mr. Curric. A description has l)een 

 published." This form has g-one under the specific name sevetxi Hy. 

 Edwards, but I am convinced, after sceino- a small series, including 

 several from Rossland, that the form varies enough to cover all the 

 descriptions — lintneri, severa, dcmhyi^ avimacula^ and slossonii — and 

 that we have but one species, not two. The western race {Kcvera) is 

 larger, broader winged and more shaggy looking, as well as generally 

 darker in color. I would arrange the forms thus: 



Smaller, narrower winged, lighter gray lintneri Grote. 



Median space not darker than the rest of wing. 



Yellow discal mark absent var. lintneri Grote. 



Yellow discal mark present var. avimacula Hudson. 



Median space largely black var. slossonii Packard. 



Larger, broader winged, darker gray race scvera Hy. Edwards. 



^ledian space not darker than the rest of wing. 



Yellow discal mark absent var. danhyi Neumogen. 



Yellow discal mark present var. normalis Dyar. 



Median space largely black shaded var. sevcra Hy. Edwards. 



The name Qim'inalls above is new. This is the usual form in the 

 West, but no one has happened to name it.

HABROSYNE SCRIPTA Gosse. 



Fifteen specimens; July 14, 15, 19, 24, 25, 27, 80, August 2, 5, 0, 7. 

 These specimens agree exactly in markings with eastern scrqda^ but 

 the general color is in all a little darker, more grayish, less yellowish. 

 There is not enough diti'crence for a varietal name, 1 think, though 

 the character is constant. Grote named the Pacific Coast form cfmt- 

 f(hin^ ])ut I have a specimen from Vancouver Island from Mr. Taylor 

 and it agrees exactly with .scrlptn from New York, not di tiering even 

 in the tint, as the Kaslo specimens do. Therefore I would make cJnif- 

 fcldil Grote a synonym of Mcrlptd Gosse. Larva^ were obtained from 

 eggs laid hy a captive female. They fed on thind)leberry. 



j5}7.</.— Elliptical, rounded, one diameter less; about 1(5 narrow 

 raised ribs, confused at the ends, joined by neat cross stria\ forming 

 cells over twice as wide as long; micropyler end larger and .somewhat
