particularly common in the west; the larva living on Apocynum androsaemifolium runs very quickly round 
on the roads; the butterfly is fond of coming to the light. 
E. pudens H. Edw. (39 f). Smaller, dirty white with a yellow ring round the neck, the forewings 
with a greyish-yellow hue on them, and a series of black dots across the abdomen. Q of a purer white. Texas. 
E. egle Drury cyclica H. Edw.) (39 f). Dirty yellowish-grey, abdomen dull yolk-coloured, with 
black dorsal dots, beneath and behind white. Eastern parts of the United States; common. — Larva on Asclepias. 
E. epagoga Dyar (39 f). Unicolorously slate-grey, similar to egle, but of a purer, not yellow tinge, and the 
abdomen of a beautiful rosy red, like in the smaller murina, with black dots over the dorsum. Mexico; rarer. 
The figured $ (Coll. Draudt) from Tehuacan, taken in September. 
E. mitis Sells. (39 f) is very closely allied to epagoga, but the $ liindwings are almost purely white, 
the $ has thick, yolk-coloured anal wool. Costa Rica; the figured $ from the Volcano Irazu. 
E. expressa H. Edw. (39 g). Thorax and wings dark brown, abdomen dark pink with dorsal puncti- 
form spots. Arizona and Mexico. Perhaps only the northern form of the preceding, since specimens from Mexico 
are reported to be of a lighter grey. 
E. bolteri Stretch (= scepsiformis Graef) (39 f). Forewings and thorax chalky white, hindwings in 
the $ dark brown, abdomen bright light red. Texas, not common. 
E. psara Dyar from Mexico has the size and shape of bolteri and resembles otherwise epagoga, but 
the wings are of a darker grey, and the abdomen is black to close in front of the red end, and exhibits in the 
S a peculiar blue reflection, by which the species is at once recognizable. Rare. 
E. murina Stretch (39 g) is smaller than the preceding, of a dirty greyish-brown, hindwings lighter. 
Abdomen dull miniate, changing to orange-red, with black dorsal spots. Texas, rarer. 
E. perlevis Grt. (39 g) greatly resembles murina , but the abdomen and the inner-marginal area of the 
hindwing near the abdomen purple-red. Arizona. 
E. albicosta Wkr. (= fumidus H. Edw.) (39 g). $ blackish-brown with a hemochrome abdomen 
dotted black and a diaphanous diffuse patch in the hindwing. The $ is much larger and has a broad, whitish 
costal stripe. The has only whitish-yellow spots on the shoulders, whilst the costal stripe is absent. Thus 
it greatly resembles (superficially) Scepsis fvlvicollis (26 a) or wrighti (26 b), which has effected the denomination 
of allied species ( scepsiformis Graef.) 
E. antica Wkr. (= zonalis Grt., para zona Dyar) (39 g) entirely resembles the $$of the preceding species, 
but the abdomen is above banded red, not dotted. Arizona, Mexico, and Central America; apparently rare. 
E. gigantea Bs. <b McD. is larger than egle (39 f) and has a scarlet abdomen on the dorsum of which 
there is a series of black spots. Also the anterior margin of the collar is red; behind this red margin of the 
collar an ochreous line. Thorax and forewings brownish-grey, the latter in the marginal quarter speckled lighter. 
Arizona. Presumably closely allied to epagoga and mitis. 42 mm. 
E. rizoma Schs. (39 g). One of the largest species. Dark brown, sides of the neck, margins of the 
shoulder-covers, a curved longitudinal stripe through the middle of the forewing and small submarginal spots 
of the hindwing white. Abdomen red with black transverse stripes which are connected by a longitudinal stripe 
across the dorsum. Brazil: Castro (Parana). 
E. castalla Bs. & McD. Thorax and wings white, forewings with a grey cell-end spot; abdomen 
red with black punctiform spots on the dorsum and sides. Arizona. Similar to Pyg. elegans, but the anterior 
tibiae not with spurs. 
5. Genus: Pygarctia Hrt. 
Proboscis absent, palpi short, porrect, £ antennae with very short double combs. Tibiae with short- 
spurs. Venation like in Chloroda, but the two veins petioled there in the hindwing run separately like in Euchaetias, 
to which the genus is closely allied. 
P. elegans Stretch. Snow-white, chest and abdomen purple red. California, Arizona, New Mexico. 
— In the form roseicapitis Neum. db Dyar (39 g) from Mexico to Guatemala the head is also purple red. 
Rather rare. 
P. vivida Grt. (39 h). Abdomen and hindwings similar to elegans, but the forewings dirty yellowish- 
grey with a yolk-coloured longitudinal stripe at the costa and proximal margin. Texas; rare. 
P. fusca Rothsch. (39 h) from Arizona and Costa Rica, has unicolorously chestnut-brown forewings 
without a paler costal margin; otherwise like the preceding.
