the second. 1 In a high latitude, or at a high altitude, we might then expect to 
find this species monogoneutic, and restricted probably to the winter form Marcia. 
And this is precisely what does occur in the island of Anticosti, and on the 
southern coast of Labrador. Mr. Couper, w T ho has collected on the island, in¬ 
forms me that he saw no examples later than 29th June, and expresses the 
opinion that no butterflies in Anticosti or Labrador produce a second brood. The 
summer is very short, and before the end of July the weather becomes cold. 
Of Tharos from Anticosti I received fourteen males, eight females. All the 
former were Marcia, Yar. D ; of the females, seven were D, one C. Of eleven 
males, two females, from Labrador, all were D. Of two examples from Lake 
Lahache, British Columbia, latitude 54°, the male is Marcia, D, the female C. 
Of four males from Colorado, all were Marcia, D; of two females one was D, 
the other C. 
On the other hand, I have received large numbers from southern Georgia, 
with the dates of capture ; several from North Carolina, taken by Mr. Morrison; 
and many from middle Texas, from Mr. Boll. Those from Carolina were of the 
first two broods of the year, and the earliest were all Marcia, C. From Georgia 
the winter examples were Marcia, B and C. Mr. Boll sent examples of five 
successive broods, beginning with February and ending with November. The 
butterflies of the earliest brood were Marcia, B. All of the summer form were 
very dark above, the black intense, the fulvous deep red, and some of the mid¬ 
summer males had the upper side lightly reticulated and the under side of the 
hind wings almost clear from markings of any sort. (Yar. C, Fig. 5-.) This vari¬ 
ety appeared also in the examples from Georgia. A similar variety appears in 
the summer form of Phaon. The Texas Tharos are of small size, like those 
from the extreme north. 
I have raised an immense number of Tharos larvse from the egg to the but¬ 
terfly. The eggs are obtained with the greatest facility, and are laid almost im¬ 
mediately after the female leaves the chrysalis. The larvse at all ' stages are 
hardy, and have not suffered from confinement. In their natural state they are 
at no period protected by a web, but are exposed and have no shelter beyond 
what the leaf over them affords. They are sluggish, differing greatly from the 
larvae of Nycteis in this respect, and a pretty sharp jar is necessary to cause 
them to drop from, the leaf. This they do in a coil, protected by their bristling 
spines from all harm. When about to moult they cease feeding, collect in groups, 
1 This habit of lethargy is serviceable in a two-brooded species, in a mountain region, and exposed to 
sharp changes of temperature. If the fate of the species depended on the last larval brood of the year, and 
especially if the larv* must reach a certain stage of growth before they were fitted to enter on their hyberna¬ 
tion, it might happen that an early frost or a tempestuous season would destroy all the larvse of the brood.
