1887.] MR. A. G. BUTLER ON WEST-AFRICAN LEPIDOPTERA. 567 



slaty black. The operculum also is, in some instances, almost en- 

 tirely of a fleshy red colour, which in other specimens is considerably 

 replaced, especially on the columellar side, by bluish-black streaks. 

 The form of the young shells is very different from that of the adult, 

 the wing-like expansions at both ends being entirely wanting, so that 

 they have a much rounder appearance. 



3. On two small Collections of African Lepidoptera recently 

 received from Mr. H. H. Johnston. By A. G. Butler, 

 F.L.S., F.Z.S., &c. 



[Received August 15, 1887.] 



Dr. Sclater has recently submitted to me three boxes of Lepi- 

 doptera, chiefly Butterflies, forwarded by Mr. H. H. Johnston, 

 F.Z.S., from the Cameroons and from the Rio del Rey to the west 

 of these mountains. The first of these collections (consisting of 

 thirteen Butterflies and three Moths) contains nothing of great 

 interest, the best specimen being a Moth, possibly unnamed, of the 

 genus Soloe, represented in the Museum collection by one specimen 

 from Ashanti. The other species are : — Myodesis martius and 

 miriam, Fabr. ; Junonia terea, Drury ; Aterica cupavia, Cram. ; 

 Romaleosoma ceres, Fabr. ; Euralia anthedon, Doubl., and E. mima, 

 var., Triaien ; Terias seneyalensis, Boisd.; Nepheronia argia,'P&hv.; 

 Aletis fascelis, Linn., and its variety A. macularia, Fabr. : all well- 

 known species. 



The second collection, which was unset, is far better, and may be 

 dealt with in detail.
