LYCASNID/E. LOGANIA. 33 
of L, ander sonit is in the Calcutta Museum, and was taken by Dr. J. Anderson on Kisseraing 
Island, Mergui Archipelago, on Ist January, 1882. It is obviously not a Zogaia, as it has only 
two subcostal nervules to the forewing, as in 4, /idna, as pointed out by Hewitson in describing 
that species ; neither is ita true Wyfolycena, as it has no tails to the hindwing, and the first sub- 
costal nervule of the forewing just after its origin touches the costal nervure. As the type of 
L. anversonii is still unique, and I have not been able to procure a specimen for dissection and 
correct description of the neuration, I leave the species for the present in the genus Zogania where 
Mr. Moore had placed it, proposing for it provisionally the new generic name Cyaniriodes in 
allusion to the character of the markings of the underside, which resemble those of Cyanéris in 
such a manner as to lead to the suspicion that it is a mimic of some species of that genus, but 
especially on account of the difference in neuration which has been detected by Mr. Doherty.

DESCRIPTION : §* UPPERSIDE, Joth wings pale purplish violet-brown, the traversing veins 
being pale violet-brown. Ci/ia violet-brown. orewing with the basal half, curving obliquely 
from the middle of the costa to the posterior margin near the angle, violaceous-white. A/éndwing 
with the lower basal and discal areas also violaceous-white. UNDERSIDE, doth wings 
densely mottled with purplish violet-brown and violet-white, interspersed with black speckles, | 
which are most prominent in a lunular marginal fascia; a white spot at the end of the 
cells. Body, antenne, and legs violet-brown.” (4Joore, 1. c.) 
There are two specimens of this species in the Indian Museum, Calcutta. taken by 
Dr. J. Anderson, on Elphinstone Island, Mergui Archipelago, on 2nd and gth March, 1882. 
The figure shows both sides of the type specimen in the Indian Museum, Calcutta. 
Logania malayica, Distant, and Z. sriwa, Distant, have been described from the Malay 
Peninsula as below.* 
In the next division, which I call the Poritia group, I have placed three genera. Zaroua, mihi, 
and Poritia, Moore, have all of the first subcostal nervule of the forewing completely anastomosed 
with the costal nervure except a small portion of the base, which alone is free. I have seen no 
specimen of Pseudodipfsas, Felder, and hence am unable to say whether or not it possesses this neural 
character, which is strictly confined to this group of Indian Zycenide, and to the genera 
* Logania malayica, Distant, Rhop. Malay., p. 208, n. 1, pl. xxii, fig. 21, female (1884). Hapirat: 
Sungei Ujong, Malay Peninsula; S.-E. Borneo. ExpaNnsE: Vale, ‘9; Female, ‘gto 1°2 inches. DEscrIPpTION: 
‘“ FEMALE. UPPERSIDE, doth wings white. Forewing with the costal margin narrowly fuscous, and the apical area 
narrowing to outer angle of the same colour. AHindwing with the outer margin very narrowly fuscous. UNDbER- 
SIDE, doth wings white, thickly and irregularly mottled with brown. Body and degs brownish.”? (Distant, |. c.) 
Mr. W. Doherty has taken this species in S.-E. Borneo, and has given me a pair of specimens. The male 
does not differ from the female except in its smaller size. 
Logania sviwa, Distant, Ann. and Mag. of Nat. Hist., fifth series, vol. xvii, p. 531 (1886); idem, id., 
Rhop. Malay., p. 452, n. 2, pl. xliv, fig. 16 (1886). Hasirar: Malacca. ExpANSE: ‘gs inches Descrip- 
TION: ‘“* UPPERSIDE, both wings violaceous-white. Forewing with the costal margin spotted with fuscous, 
and the apical area (not quite reaching to the outer angle) dark fuscous. C7/iaof the hindwing spotted with 
fuscous, UNDERSIDE, doth wings fuscous-brown with darker blotches, and irrorated and speckled with greyish- 
white ; this whitish coloration is most prominent on the forewing at the apex and outer angles, and on the hind- 
wing it appears as an irregular broad subcostal streak. MWindwing also more darkly marked than the forewing. 
Body above brownish, beneath greyish ; Zegs very pale brownish with dark annulations.”’ (Distant, 1. c.) 
Mr. Doherty records this species (Journ. A. S. B., vol. lviii, pt. 2, p. (1889) from Mergui, where the 
types of LZ. marmorata, Moore, were procured. I have seen the single female he obtained ; it appears to differ 
from L. marmorata only by the greater prominence of all the markings of the underside. I am very much 
inclined to think that Z  sy/wa cannot stand as a species distinct from Z. mazmorata, and most likely the 
“ Miletus” lahamius of Kheil (Rhop. Insel Nias, p. 27, n. 77, pl. v, figs. 28, 29 (1884), from the Island of Nias, 
will hereafter be proved to be another synonym of the same species. Mr. Doherty, speaking of this Mergui 
specimen of Z. sriwa, says that : ‘‘ It is very possibly distinct from ZL, »armorata, Moore, but the bad state of the 
types of that species makes it difficult to decide. On account of the short legs, I retain this species in Logania, 
though the tibie are but slightly thickened. Between this form and the true Zogazéas, with the ‘ apices of the 
tibia globosely incrassated,’ I believe every gradation can be found. Of the true Loganras a species [undescribed] 
eccurs at Bassein, Burma; it is one of the smallest and obscurest of Indian butterflies. ‘he type species, L. 
‘malayica, Distant, seems rare in the Malay Peninsula (where a number of other forms occur), but I found it 
rather common in south-eastern Borneo. The genus is also represented in Celebes,”
