SATYRINAE: ENODIA POllTLANDIA. 185 



instances of its ca[)turc on record are two battered specimens from Jeffer- 

 son (Scudder) and three or four at Suncook, N. II. (Thaxter) ; a few at 

 Orono (Fernald), and Bangor, Me. (Braun), and one at Jamaica Plain, 

 iNIass. {(-(dl. Bost. Soc. Nat. Hist.). 



Haunts. Mr. Allen states that on the western [)rairies it occurs in 

 deep, damp ra^•ines in woods skirting the rivers ; the specimens from Jef- 

 ferson were taken in a highway through a wood near a small stream of 

 water. Those from the Connecticut Valley in a shady road through a 

 mountain gap or on the mountain sides. It is everywhere rightly regarded 

 as a forest species. 



Life history. According to Mr. Emery, the butterflies are to be found 

 about Mount Tom the last of June ; good specimens were also taken by him 

 the first week in July and a few specimens may be found there until the 

 end of the first week in August. Gosse reports his single specimen from 

 Compton to have been taken in July, and the two badly broken ones from 

 northern New Hampshire were found late in the same month. The speci- 

 mens from the Lake of the Woods, were taken between the middle of July 

 and the middle of August ; those captured in Iowa by Mr. Allen during 

 July and early August ; the Orono specimens in the latter half of July 

 and the Montreal specimens in August. Probably, therefore, the butterfly is 

 single brooded in the north and lays eggs in August. September 3 is the 

 only date of egg-laying known — in northern Ohio, but this must be re- 

 garded as exceptionally late. From this and from Mr. Edwards' experi- 

 ments with rearing those from northern Ohio, it is pretty certain that the 

 winter is passed as a caterpillar in an early stage of life. 



Further south there appear to be at least two broods. Mr. Edwards, 

 writing from West Virginia, says "I have taken the buttei*fly, in different 

 years, as early as 18th May, and through each month to 1st September, 

 and I apprehend there are three annual generations here, the first in Mav, 

 the second middle of July, the third late in August, as I have taken fresh 

 examples at these times." Dr. Chapman finds specimens in Florida, from 

 the middle of February to the beginning of May ; fresh specimens were 

 taken at the end of May and again in the middle of October. He also re- 

 cords one capture in the middle of August, as does Gosse in Alabama. 

 Abbott in Georgia took the insect April 25 and bred it May 20. It 

 would seem probable from these scanty facts that May and August are the 

 culminating times of the southern broods, and that other appearances of 

 fresh material must be due to the lingering of some individuals in their 

 early stages, so common a phenomenon in neighboring satp'ids ; and it 

 would appear as if the winter might sometimes be passed in chrysalis in 

 the extreme south. Doubtless the account and illustrations of this insect 

 in the forthcoming munber of Edwards' sumptuous Butterflies of North 

 America will add considerably to our knowledge.
