THE CANADIAN ENTOMOLOGIST. 221 



Habitat : Calgary, Canada, in June (F. H. Wolley Dod). 



Four males and four females, the latter on the whole a little more 

 reddish shaded. There is little difference between the specimens, and 

 altogether they differ from finitima^ with which I was at first inclined 

 to consider them identical, by the much paler ground and much less 

 contrasting maculation. There is a mere shade of red and the median 

 space is hardly darker. Antennae a little marked in the male with small 

 tufts of short lateral bristles. 



Nephelodes pectinattis, n. sp. 



Ground colour luteous, with tendency to either a greenish or a 

 decidedly red tint. Head and thorax immaculate. Primaries without 

 defined markings, the median space deeper in colour, all beyond it more 

 smooth, not powdery like the basal space. T. a. line single, oblique, 

 a little outcurved, hardly darker than ground. T. p. line single, a little 

 better defined, outcurved over cell, evenly oblique below. S. t. line 

 marked by a narrow, broken, obscure darker preceding shade. Orbicular 

 an undefined, somewhat paler, round blotch. Reniform a little better 

 marked, paler, not outlined, defined only below and outwardly. 

 Secondaries smoky or blackish, the fringes of the palest ground colour 

 of primaries. Beneath reddish powdered, primaries with disc smoky, 

 secondaries with a discal lunule. 



Expands 38-42 mm. = 1.5 2-1. 68 inches. 

 Habitat : British Columbia ; Corfield, Vancouver. 



Two males (the collectors not indicated on the labels). The 

 species resembles the common eastern form^ and so I have named it for 

 more than one of my Northwestern friends, I believe ; but more careful 

 study shows a difference in the character of the male antennse. In 

 minians the pectinations are rather short and lengthened by a curved 

 bristle at the tip. In pedinatus this bristle is absent, but the branches 

 themselves are longer and a little enlarged toward the tip. The differ- 

 ences are thus obvious and emphasize the rather scant superficial 

 characters. The specimen from British Columbia has a peculiar 

 greenish tinge to the ground which I have not seen in the eastern 

 species. That from Vancouver is washed with red-brown. It is prob- 

 able, therefore, that quite a range of colour difference will be found, as in 

 the case of the eastern form.
