Show 578 MR. H. H. DEUCE ON BORNEAN LYCEENIDEE. [June 18, and spots, whereas the ground-colour is very pale yellowish grey with pale brown fasciae and a double row of black marginal spots to each wing; the two spots nearest to the anal angle sprinkled with blue scales. The upperside is dull violaceous silvery blue. Possibly N. kerriana, Distant, is conspecific with N angusta, but unfortunately I have not a specimen for examination. The underside of the figure given in Ehop. Malay, appears to agree well with that of N. angusta, but the upperside has a broader black outer margin. N. azureus, Eober, as figured by Herr Semper (Eeise Philip. Insel. p. 177, pi. xxxiii. figs. 1, 2), and which we possess from S. Celebes (Doherty), is a closely allied species. Herr Bober's figure and this one, however, do not agree very well. NACADUBA ATRATUS. Lyccena atratus, Horsf. Cat. Lep. E. I. C. p. 78 (1828). Cupido akaba, Druce, P. Z. S. 1873, p. 350. Kina Balu ( Waterstr.) ; Labuan (Low); S.E. Borneo, near Ban-jarmasin ( Wahnes). Kina Balu specimens are slightly darker on the upperside than those from Labuan and S.E. Borneo. I have examined the type of C. akaba, and can find no character to distinguish it. NACADUBA BEROE. Lyccena beroe, Feld. Eeise Nov., Lep. ii. p. 275, pi. xxxiv. fig. 36 (1865). Nacaduba beroe, Distant & Pryer, Ann. Mag. Nat. Hist. ser. 5, vol. xix. p. 267 (1887). Sandakan (Pryer). I include A7", beroe here on the authority of Messrs. Distant and Pryer. Typically, I think it can be distinguished from N. atratus by the paler ground-colour of the underside aud by the fascia being much wider. NACADUBA BHUTEA. Nacaduba bhutea, de Nicev. J. A. S. B. vol. Iii. pt. 2, p. 72, pi. i. fig. 13 (1883). Kina Balu (Waterstr. and Everett) ; Labuan (Low). The ground-colour of the Bornean examples I have examined is ochreous on the underside. NACADUBA ARDATES. Lyccena ardates, Moore, P. Z. S. 1874, p. 574, pi. lxvii. fig. 1. Sandakan (Pryer) ; Labuan (Low). The tailed form only. NACADUBA ALUTA. (Plate XXXII. figs. 13 d , 14 $ .) Cupido aluta, Druce, P. Z. S. 1873, p. 349, pi. xxxii. fig. 8. Sandakan (Pryer) ; Labuan (Low <$f Wahnes). The figure given in the P. Z. S. is a very bad one and bears but slight resemblance to the insect. It is, in m y opinion, although |
