PEOTEOPTERYX. 69 



ferruginous or ochreous ocellated spot ill-defined^ enclosed by paler streaks meeting at the 

 anal angle: cilia greyish brown. Hind wings fuscous brown; cilia paler. 6 S, 3 ?. 

 Expanse of wings 15-17 millims. 



About 40 specimens were taken in June 1871^ in Mendocino and Lake Counties^ 

 California. 



Var. a. The costal and apical portions of the fore wings mottled brown^ with several 

 short whitish geminated costal streaks ; the elongated dorsal blotchy as also the head and 

 palpij ferruginous : antennse brown. 



Var. /3. The head and palpi reddish brown ; the costal and apical portion of the wings 

 reddish brown, mottled Avith darker brown ; the elongated dorsal blotch and ocellated spot 

 white tinted with ochreous ; some short whitish geminated costal streaks. 



Var. y has the head and palpi, together with the costal half of the fore wings and the 

 ocellated spot, dirty whitish, with some short chocolate-brown costal streaks, the elongated 

 dorsal blotch chocolate-brown, the apex tinged with brownish fuscous. 



In some varieties the character of the ornamentation is somewhat changed, the dorsal 

 blotch being obsolete or merged in the generally mottled appearance of the wing, in which 

 various shades are represented. Among all these, however, there appeared to be scarcely any 

 variation in size. 



Later in the year I met with a smaller form, taking sixteen or eighteen specimens on 

 Crooked River, in Oregon, in September. These are exactly similar in structure, but exhibit 

 some differences in the general character of their ornamentation, which leads to a suspicion 

 that they may be found to belong to a separate species. I have figured two of these specimens, 

 in which it will be seen that the dorsal blotch is, as it were, continued into the ocellated patch, 

 dividing the whole length of the wing more distinctly into two halves. 



Some specimens of the larger form approach this colouring ; but in none is it so distinct, 

 and whereas in those it appears to be the exception, among the smaller specimens taken in 

 September it is almost the rule. I shall not, however, venture to describe those two forms as 

 specifically distinct, but would rather consider the smaller one as the more northern form, or 

 perhaps the second or autumnal brood of the larger. 



Var. 8. Head, palpi, and cilia yellowish grey : antennse and costal half of fore wings, 

 together with the extreme apical margin, dull brown ; the dorsal half, including the obsolete 

 ocellated patch, stone-grey, the division between the two colours evenly undulating. 



Var. e. Head and elongated darsal blotch, together with the obsolete ocellated patch, 

 ferruginous ; the costal half and extreme apical margin mottled whitish grey and dark brown, 

 with short geminated pale costal streaks and an undulating line along the middle of the wing. 

 3 cJ, 5 $ . Expanse of wings 14 millims.
