NOTES ON. THE GENERIC NAMES OF INDIAN THECLINA AND 
AMBLYPODIINA (LEP. RHOP.) 
By 
Capt. N. D. RILry, F.E.5., F.Z.S. 
The following is a brief summary of notes made for my own guidance at vari- 
ous times, and may help to stabilise the nomenclature of this group of Indian 
Butterflies. It is only the older names that present any difficulty, the later 
authors having been more careful to fix the types of such generic names as they 
have proposed. I do not consider the fact that a generic name has been, for 
whatever length of time, employed in a wrong sense, is in any way a justification 
for its continued use in that sense. The sooner it is set right the better ; the 
future of Entomology is likely to be of greater duration than its past. 
I have introduced a few names which, though not now applied to the groups 
in question, were formerly so applied, such as LYCAUNA, POLYOMMATUS, 
ete., about which there has been considerable argument in the past, and also 
a few generic names proposed by Tutt, with which one may in the future have to 
reckon. 
For the sake of convenience I have arranged the genera alphabetically stating 
in each ease what I consider is the type. This is solely from the point of view 
of nomenclature : whether the genera are entomologically valid or justifiable or 
not I have not tried to decide. TJ. 9. after a specific name implies that that 
species is the type of the genus because it was designated such by the author of 
the genus at the time he proposed it: S. S. because it was the sole species re- 
ferred to the genus by the author at the time he proposed it. In all other cases 
the reasons for designating any particular species as the type are given.

Beng. p. 41. de N. 
AMBLYPODIA, Horsf. Cat. Lep. E. I. C.  1829., paidanus, 
p. 98. Cramer. 
Horsfield introduced the generic name Ambl; ypodva for a number of species 
which he divided into five subsections, viz., (1) narada, (2) vivarna, (3) apidanus, 
centaurus, helus, ewmolphus, (4) phocides, (5) vulcanus, lohita, syam, timoleon, 
jalindra, longinus, erylus, jangala, vidura, etolus, representing in fact many 
genera.* 
Doubleday (List Brit. Mus., p. 23, 1847) employs it for a number of those 
species enumerated by Horsfield, and others. 
Westwood (Gen. Diurn. Lep. p. 477, 1852), employs it in a similar sense, but 
also expressly states that ‘‘ the types of the genus’ are the large Indian Amb. 
centaurus, apidanus, helus, anthelus, etc., thus limiting the possible type of the 
genus to one of the first three of those species, since anihelus is not mentioned 
by Horsfield. The type was finally specified by Scudder (Hist. Gen. Butt. p. 108, 
1875) as apidanus, which must be accepted. 
It is unfortunate that, following Boisduval (1870), authors should consistently 
have ignored the earlier workers and taken narada as the type. Obviously, 
in view of Westwood’s restriction, it could not be the type under any circums- 
tances.

APHNA US, Hiibner. Verz. bek. Schmett. 1822-3. orcas,

Hiibner gives pene two species, vulcanus and orcas. No action was taken by 
any author in any way to affect the case till Scudder (Hist. Gen. Butt. p. 116, 
' 1875) selected orcas as the type. This he was perfectly at liberty to do, and his 
* He also States (p.111 1. c.) that he oes “ the species of the third section to be typica) 
of the genus.” See also Riley. Entom., 1922 25.
