24 DIURNAL LEPIDOPTERA. 



part. The present species feeds, while in the larva state, 

 on the mouse-ear and everlasting. 



No. 30. — Apatura Celtis. — Is figured in Boisduval and 

 Le Conte, but no description of it is furnished in their 

 unfinished publication. The larva is supposed to feed on 

 the Celtis. One specimen was taken at Dayton two years 

 since, and was presented to me by the late Mr. Jenison. 



No. 31. — Satyrus Alope. — To the same respectable ento- 

 mologist I was indebted for a pair of this insect. Another 

 specimen I have received from West Chester, New York, 

 and also observed it in Wisconsin. It seems not to be 

 very abundant in any known locality. All the species of 

 this genus feed upon coarse grasses. 



No. 32. — S. Oanthus. — In Northern Ohio this species is 

 somewhat rare, while in the centre of the State and 

 especially in the western prairies it is excessively abun- 

 dant. 



No. 33. — S. EuRiTHius. — Is subject to the same remark. 



No. 34. — S. Andromacha. — Is among the most rare of 

 our butterflies, and even on our prairies is only occasion- 

 ally seen. 



No. 35. — Leminitis Ephistion. — This is an abundant spe- 

 cies in every locality. 



No. 36. — L. Arthemis. — Is rarely seen in this vicinity. 

 I have met with it in only two or three instances in Ohio. 

 At Racine it is more common among the oak forests. It 

 is one of our most active and handsome butterflies, though 

 its plumage is plain. From its resorting almost exclu- 

 sively to oak forests, it is inferred that the larva obtains 

 its sustenance from that tree. 



No. 37. — L. Missippus. — This species is equally common 

 with No. 35. The larva is found upon several species of 

 oak.
