SATYRUS II.. III. 



tertTi-ades of New York. Of 16 <? examined, 14 have 6 ocelli, 1 has 5, 1 has 

 2. Of 19 ?. 10 per cent, have 6, 50 per cent, have over 3 ; the males agreeing 

 with Nqihde of Canada. 



Boojjis was described as distiriguished from Nephde by the absence of ocelli 

 on under side of hind wings. The male is dark brown, and the ocelli on under 

 fore wings have nearly always yellowish rings, often faint. In the female, the 

 rings are enlarged, and sometimes the field is yellow-tinted, and occasionally this 

 is nearly clear yellow, making a In-oad, but clouded, band. Tliis again resembles 

 some of the intergrades before spoken of. Of 5 c?, 4 have 2 obsolescent ocelli 

 beneath hind wings, 1 has 1. Of 7 ?, 1 has 3, 5 have 2, 1 has 1 ; so that there 

 is manifestly a decrease in the number of ocelli, as was pointed out by Dr. Behr. 

 Fig. 6, Plate III., is a good representation of Boojns ? . 



Some Nephele females are undistinguishable from females of Boopis, but the 

 ditt'ereuce between the males is more marked, the foi-mer showing a full comple- 

 ment of small ocelli in most cases, and but three or less very rarely, the other 

 never exceeding three, so far as I have observed. Boopis flies from Arizona to 

 British Columbia. 



These Satyrids live in grassy fields, or in open woods in which much grass 

 grows. The eggs are laid on grass and the caterpillars make that their food. In 

 many sections of the country, the butterflies swarm in their season, and were it 

 not for the fact that grass is usually cut for hay at the time the caterpillars are 

 maturing, whereby countless numbers must be destroyed, they would swarm 

 everywhere in their localities. There is but one annual brood. In the Catskills, 

 the butterflies begin to appear about middle of July, and in certain places hun- 

 dreds may be taken during a summer's day. On tlie flowers of the hardback, 

 Spirea tomentosa, which blooms in old fields in July, multitudes gather. So ou 

 buckwheat Avhen in blossom. The flight is low, with tremulous wing, and for but 

 a short distance. About the end of July, the females are ready to deposit their 

 e^ra's, which hatch durinij; middle and last half of August. The caterpillars so 

 into lethargy at once, descending to the base of the plant, and must revive the 

 next spring, as soon as the frosts are over, and warm rains make the fields green. 



Mr. Scudder, in his " Butterflies," speaks of the multitudes of Alope {Marl- 

 thna) to be seen at times on Nantucket, "• a continuous stream." I spent some 

 time on Martha's Vineyard, at Oak Bluffs, in July, 1877, and on the gras.sy plains 

 back of the town I searched daily for butterflies. The first AJope-Mdrifinia 

 seen were two males fresh from chrysalis, 23d July. On 2Gth, the first female 

 appeared, and I took that day 12 (?, 1 ?. I left the Vineyard, and Mr. T. L. 

 Mead, who had come there just at that time, luidertook to get eggs for me. On 

 10th August, or fifteen days after the first female had been .seen, he began to
