Th. chalcis Behr ( 154 !i) is somewhat smaller, darker brown, also beneath darker, with mmh duller ckalch. 

 markings, without any white. California, Utah. 



53. Grunus-Group (Hahrodias Sciuld.). 



Til. grunus B.fd. (154 i) is above light orange-brown, in the dise .still lighter, particularly the (^^^ 'jrunus. 

 are often bright orange. The under surface is likewise reddish-brown with 2 rows of tin3^ often indistinct 

 antemarginal spots; between the median veins and at the anal angle, often also between both, small black 

 spots with green-silvery pui^ils. ■ — The bluish-green, short-haircl and lighter striped larva lives on Quercus 

 chrysolepis. California, Nevada. 



54. Crysalus-Group (Hypaurotis Scudd.). 



Th. crysalus Ediv. (154 i) is a large species differing greatly from all the others we know. x\bove crysnlits. 

 blackish-brt)wn, in the basal half of the forewing and subapieally, as well as in the disc of the hindwing, lilac, 

 towards the anal angle of both wings spottend in orange. Beneath greyish-brown with darker discal streaks 

 bordered on both sides bj' white, and with dark, distally white-tinged, postdiscal stripes on both wings, on 

 the hindwing also with a proximally whitish additional basal streak; blackish submarginal lunae are proximally 

 bordered by white on both wings, on the forewings analwards distally by orange-yellow; on the hindwing there 

 is behind them towards the anal angle an increasing bluish-silvery dusting, between the median veins and 

 at the anal lobe orange-red, black-pupilled spots being often connected by a bridge. California, Arizona, Utah, 

 and South Colorado. — The form cititna Edir. has above no orange spots and is beneath more grey-coloured, ciiima. 



55. Calanus-CJrouj). 



Th. calanus Hbn. (= falacer Godt., inorata Grote d- Bob.) (154 i) is above plainly dark-brown with ralanus. 

 an oblong-oval — twice as long as broad — lighter scent-spot in the distal half of the cell; beneath nearly just 

 as dark brown with postdiscal and submarginal rows of darker spots, distally bordered by fine bluish-white 

 lines and similar discal spots. Between the median veins and above them, as well as at the anal angle, there 

 are dark-red .spots, the space between them is densely strewn with bluish- white. — f. lorata Gmie <£• Mob. is lomta. 

 somewhat smaller, beneath lighter with le.ss distinct small spots. — The larva lives on oak-trees. In the Atlantic 

 States and the Rocky Mountains it is common. 



Th. heathii Fletch., described only according to 1 '^, is unknown to me. Above like calanus, beneath heafhii. 

 fawn-coloured with jiearl-grey postdiscal spots, 4 of which on the forewing are oval, bordered on both sides 

 by a darker band, 5 of which on the hindwing are more four-cornered, bordered on both sides by a black band; 

 marginal spots as in cnlmm.i, towards the anal angle likewise scarlet, between them a plainly white, not blue 

 spot. Expanse of wings 2(i mm. Manitoba (Long River). 



Th. Ontario Edw. resembles melinus (159g); expanse of wings 26 mm. On both surfaces brown, the Ontario. 

 forewing with a large, smooth, oval scent-spot, the fringes dark, in some places white; hindwings before the 

 anal angle with some small, reddish-yellow scales. Beneath lighter brown, the small spots of the discal row 

 touch each (jther on the forewing excejjt 2; a distal row of more obsolete spots. On the hindwing the spots of 

 the distal row are separated, the row straight, forming a W in the anal pait. In front of the border black and 

 bluish bordered interneival spots the 4 apical ones of which are small, the 5 th and 6 th marked in orange-red. 

 Near the base of the tail a heap of blue scales ; in the anal region a red spot marked in black and white. Based 

 upon 1 cJ from Ontario (July). 



Th. liparops Bsd. (= strigosa Harr.) (154 i) is above brown like the others, beneath maybe some- Hixirops. 

 what greyer, marked just the same, but by the widening of the dark spots the fine white stripes are much more 

 apart from each other and often very indistinct. — The larva lives polyphagously on the most different foliage- 

 trees, on Rosaceae and Ericaceae. Distributed in the North Atlantic States and the Rocky Moinitains, but 

 nowheres common. 



Th. edwardsii Snd.s. (= fabricii Ky.) (154i) vice versa differs beneath from calanus by a considerable i'(lwar(l.<iii. 

 diminution of the small dark spots which are mostly all round bordeied l>v white, so that small eyespot-rows 

 are ijroduced; above there is hardly any difference, i^erhaps the brown tinge is somewhat lighter, the scent-.spot 

 is thrice as long as broad, appearing therefore narrower. — The larva lives on oaks. In the Northern States, 

 mostly common. 



Th. wittfeldi Edw. (154 k) is larger than the preceding, above differing by the darker colour and a u-illfeldi. 

 large orange spot between the median veins and a fine bluish-white, proximally black, marginal line analwards. 

 Beneath the white lines are more contiiuious, placed nearer to the border, the red anal spots larger and more 

 intense, the space between them less blue. Florida.
