and rather strongly bent outward below costa, the fifth line just preceding the 

 prominent discal spot; between the 3d and 5th lines traces of a paler band, 

 scarcely visible except at costa and divided by the 4th line; postmedian line 

 which forms the outer boundary of this darker area irregularly dentate with 

 rather prominent teeth below veins 3, 4 and 7, inclined obliquely outwardly from 

 costa to vein 4, then inwardly oblique to slightly beyond middle of inner mar- 

 gin; beyond the postmedian line the color of the wing is decidedly paler, mixed 

 with grayish, with the exception of a costo-apical patch of the same color as 

 the basal area; two wavy dark lines, more or less parallel to postmedian line, 

 cross the subterminal area; a pale s. t. line, scarcely visible except where it 

 crosses the dark apical patch; fringes smoky, slightly checkered. Secondaries 

 unicolorous orange-yellow with more or less distinct dark terminal line. Be- 

 neath primaries tinged with orange with the maculation of the upper side slightly 

 visible and with a small, dark costal blotch at inception of postmedian line; sec- 

 ondaries as above without the terminal dark line. Expanse 25 mm. 

 Habitat: Palmerlee, Ariz. 3 $,3 ?. Types, Coll. Barnes. 



This species has probably been confused in collections with 

 aurata Grt. (daira Druce) (PI. XX, Fig. 9) with which it is very simi- 

 lar in general type of maculation, differing however in the much more 

 sombre coloring with none of the pale basal area characteristic of 

 aurata. The 9 's of illustrata are generally paler in terminal area and 

 better marked than the S 's. We figure the types of illustrata as well 

 as a $ of aurata from Redington, Ariz. 



Spargania magnoliata ruptata var. nov. (PI. XIX, Fig. 1). 



Typical magnoliata Gn. is a form of the Eastern States and Can- 

 ada, having apparently as synonyms incommodata Wlk., placidata Wlk., 

 ziczacata Wlk. and cumatilis G. & R. On the northern Pacific Coast it 

 is represented by pemotata Hist. (PI. XIX, Fig. 2) described from 

 Alaska and extending southward to Vancouver Is., B. C. ; this form is 

 larger and generally duller in coloration. In California at lower levels 

 we find the race quadripunctata Pack, which as far as can be told from 

 the poor type specimen in the Cambridge Mus. Coll. is very similar to 

 pemotata but smaller and generally brighter in color, the green of the 

 primaries being less tinged with gray. We have two 9 's from Deer 

 Park Spgs. in the Lake Tahoe region of the Sierra Nevadas which 

 seem to represent a high altitude form characterized by the prominent 

 white subterminal band with only traces of a central line, the white 

 color breaking through the dark terminal area between veins 3 and 4 

 and touching the outer margin ; the hind wings are considerably paler 

 than in pemotata. This may represent a good species but for the 

 present we prefer to consider it a race for which we propose the name
