Show 28 MR. R. TRIMEN ON BUTTERFLIES FROM [Jan. 16, between typical A. aglaonice and the variety now under notice, having the transparent .spots and basal fuscous moderately developed in the fore wings ; but the two females differ from the Mineni Valley female only in the much clearer transparent spots. 20. ACRiEA NATALICA, Boisd. Acrcea natcdica, Boisd. App. Voy. Deleg. dans l'Afr. Aust. p. 590. n. 57 (1847). This species is numerous over a wide stretch of Eastern and South-eastern Africa. Mr. Selous's collection contains 36 specimens, 29 of which were captured in Christmas Pass. 21. ACRJEA ANEMOSA, Hewits. Acrcea anemosa, Hewits. Exot. Butt. hi. pi. 8. figs. 14, 15 (1865). The only examples are an unusually small male, captured at the Sikuva Eiver on 4th March, and an ordinary female taken in Christmas Pass on the 16th February. In ' South-African Butterflies ' (i. p. 158) I have described an " Aberration-? § ," from Damaraland, in the Hewitson Collection, in which on the upperside there is white clouding about the extremities of the nervules in the fore wings, and a large white cloud in the hind wings replacing nearly aU the reddish ochre-yellow of the central band. Mr. Selous in 1889 sent m e a male presenting the same peculiarities, and also the distinction of the fore wings being salmon-pink without any tinge of the usual yellow-ochreous ; this very striking example was captured a little south of the junction of the Chobe and Zambesi. 22. AcRiEA ACRITA, Hewits. (Plate IV. fig. 4, var., J.) Acrcea acrita, Hewits. Exot. Butt. hi. pi. 8. fig. 18 (1865); Trimen, op. cit. hi. App. i. p. 381. n. 381 (1889). There are 19 examples of this fine Acrcea from Christmas Pass, 1 from Sikuva Eiver, 3 from Mineni Valley, 1 from Vunduzi Eiver, and 2 (of a larger variety) from Eevue Eiver. With the exception of the two last-named, all may be regarded as belonging to the typical form ; the males expand from 2 in. 2 lin. to 2 in. 5| lin., the females the same. Both sexes show a good deal of variation as regards the width of the apical fuscous border in the fore wings, and in the numbers (7 or 8) and relative sizes of the rounded discal spots in the hind wings; the subbasal black spot in the fore wings is much reduced in several males and females, and is wholly wanting in two of the latter. The males also exhibit on the upperside much instability in respect of the width of the hind-marginal border of the hind wings and the distinctness of its enclosed spots, the border being usually more or less extended internally in a different manner between the third median nervule and the anal angle, and the enclosed spots giving every grade from perfect development to (in one example) complete |
