lOG [October, 



until the 26th of May, wheu I noticed a diminution in size of the caae, 

 and knew I had lost the first moth ; but I secured the second moth, 

 a fine female specimen which appeared on June the 5th. 



On opening the deserted remains of the cases, I found tliat of 

 the first moth fallen to decay, while the one just vacated was oval 

 within, five-eighths of an inch in length, thickly and smoothly lined 

 with whitish silk ; the old blackish cast skin of the larva, and the 

 broken pupa skin, remaining in it ; this pupa skin was a little more 

 than three-eighths of an inch in length, with a large development of 

 the wing-, antenna-, and leg-cases, the latter projecting a little free 

 from the body, which was smooth and shining, the head and thorax 

 rounded off, the abdominal tip rather blunt, and but little produced 

 beyond the last ring, and having on each side a small angular projection ; 

 the circular flat button-like spiracles very slightly raised above the 

 surface : the colour was a warm brown, and shining.

ipiSCEIPTION OF A NEW SPECIES OF MYRINA FROM W. AFRICA. 

 BY W. C. HEWITSOJf, F.L.S. 



A small collection of butterflies brought from tlie Cameroons and 

 very liberally intrusted to my care by Mr. G. B. Medley, though not 

 rich in rare things, contains a very beautiful new species of Myrina, 

 which I characterize as follows : — 



Mteina Gexttba, sp. n. 



TTpfer-side : ultramarine blue. Anterior wing with the costal and 

 outer margins, and an unusually large central discal spot, dark brown. 

 Posterior wing with one tail ; the costal margin brown, the outer 

 margin dentated, black, narrow, the fringe white. 



Under-side : white, with the outer margins broadly brown, traversed 

 inwardly, where it joins the white by a rufous-brown baud bordered 

 on both sides with dark brown. Posterior wing with a black spot at 

 the base of the tail, bordered broadly with orange ; the lobe black 

 crowned with blue, a black spot near it irrorated with blue ; two lunu- 

 lar brown spots towards the apex bordered with white, the outer 

 margin black bordered inwardly with white. 



Exp. Iv/ij inch. Ilab. Cameroons, West Africa.
