same state as they were forty years ago. It is one of tliose un- 

 accountable cases which have been often noticed by entomo- 

 logists, that insects disappear for no visible reason, and, as 

 often happens, may reappear as commonly as formerly at some 

 future time. 



Satyrus Semele is to be met with along the rocky faces, at an 

 altitude of 400 feet and upwards, from one end of Moncreiffe 

 Hill to the other. It visits the lower part of the hill occasion- 

 ally, but its habitat is among the bare faces towards the summit. 

 I have not observed any variations in size or markings. 



S. Janira is common everywhere, and although I have taken 

 specimens that vary slightly in the ground colour, I think it is 

 to be attributed more to the eifects of the weather than to any 

 variation in the insect. 



S, HyperaJithics. — Not an uncommon insect, though local. It 

 is to be met with every season in the same localities in about 

 equal numbers, but it varies considerably in size and in the 

 number of the Ocelli on the wings. I have four specimens now 

 before me, varying as follows : — 



I St. Two ocelli on the superior wings and two on the posterior 

 — the latter being slightly the largest. 



2nd. Three on each of the superior wings, two on the 

 posterior. The centre ones on the superior being con- 

 siderably larger than any of the others, and the lowest 

 one of the three being only a small black dot. 



3d. Two distinct very small black dots on the right superior, 

 on the left only one, in the right posterior none, in the 

 left a very minute though perfectly clear ocellus. 



4th. No ocelli on the two superior or on the right posterior, 

 but a distinct though minute one on the left. 



In No. I, three out of four of the ocelli on the front wings 

 have a white central spot, in the 4th it is absent, those on the 

 posterior wings have all distinct white centres. In No. 2, eight 

 of the ocelli have distinct white central spots, in the lower one 

 of the three on each superior wing they are wanting. In Nos. 

 3 and 4, the white central spots are absent. In each case the 

 outer circle is lighter than the ground colour of the wing, the 

 inner one darker, and the central one pure shining white. 



Cceiiojiyinpha Davits has been reported from Moncreiffe Hill, 

 but I have not seen specimens, so shall pass it by unclaimed. 



C. Pamphilus is common in every open space, and requires 

 no comment.
