4. Terias vaUivolans. (Tab. XXYI., fig, 17 S .) 



Teriax mffimfam, Butler, Ann, & Mag. Nat, Hist, ser, 6, vol, iL p. 420, n. 71 (18 S3). 



This species or variety appears to differ only from T, hembe by the narrower black marginal borders 

 to the wings.* 



Exp. wni ; _v, If; mill. [in. 



Had, — Malay Peninsula ; Singapore (Kerr— coll. Diet.)- — Philippine Islands ; Mindanao (' Challenger' 

 Exped.). 



Tbe reason why the writer considers it probable that this is but another variety of 

 7\ iiecabe is partly derive tl from the remarks of Mr. Butler himself, who describes T. valHvolans 

 as "in pattern and coloration nearest to Terias martesii, var, e (Trans. Ent. Soc, 1880, ph vn, 

 fig. 5), but with narrower wings, &c." Now as Mr. Pryer has stated that his breeding 

 experiments have proved that IT, mariesii and its varieties are together but seasonal forms of 

 T. hecahet I we must, if we credit Mr. Pryer, as certainly doubt that we are here dealing with 

 specific differences. 



5. Terias pumilaris, var. (Tab. XXYL, fig. 10 ff .) 



Taum pumilaris, Butler, Proc. ZooL Soc. 1875, p, 617, n, 86, t, 67, f. 7 J (1875); Trans, Linn. Soc. ser. 2, 

 Zooh vol, L p. 650, n. 5 (1677). 



This is a species enumerated by Mr. Butler in his list of the Butterflies of Malacca 

 collected by Capt, Pin will, and the specimen here figured has been compared (in company with 

 Mr, Butler) with the type of T. pumilaris, from which it slightly varies. I give a copy of 

 the original description : — 



" Sulphur-yellow ; primaries with the costal margin blackish, outer margin rather broadly and 

 regularly brown -bordered, the border being biainuated within the median interspaces ; secondaries with 

 brown spots at termination of the nervnres, sometimes concurrent ; body blackish : wings below paler 

 yellow; nervnres terminating in black dots; an annular marking at the terminations of the discoidal 

 cells ; secondaries with an annular marking on the subcostal area near the base ; body pale dull yellow : 

 expanse of wings 1 inch to 1 inch 3 lines." 



Has. — Malay Peninsula ; Malacca (Pin will — Brit. Mus.) ; Singapore {Kerr— coll. Disk). — New 

 Hebrides; Tanna, Vate (Brit. Mus.}* 



Mr. Butler adds to his description the following remarks : — " This species belongs to the 

 7. hccahe group, but differs from all its allies in its narrow elongated primaries with more 

 rounded apex : the sinuation of the outer border is also much less marked ; so that the insect 

 has a very different aspect/' 



The specimen here figured, and which has been compared with the type, does not bear 

 out these distinctions, and as Mr. Butler could find no " distinguishing characters" to separate 

 the Malayan form collected by Capt* Pin will from the representative in the New Hebrides," § 

 we can see that it varies in itself. Heretical as it may appear, the writer believes that any 

 Malayan lepidopterist can prove that this also is but a form of T. hecabe. 



The minute dark outer marginal apots exist as m T* hzcahc, but have unfortunately been overlooked hj our artist, 

 1 Trans. EnU Soc. 1882, p. -188 -'J. } This figure is very indifferent and confusing.
