first measuring from fio to 70 mm. Qengtli of forewing], whereas the latter measure^ 

 from 76 to 84 mm. 



The forewings of my Java males oi anvphrysMS vary in lengtli from 03 to 78 ram., 

 those of my cuneifer from 64 to 80, and tliose of my Bornean T. amphryam ab. 

 ntficollis (Butl.) from Borneo 57 to 79. 



(2) The iipperside of the forewings is i-ather browner, less black in cuneifer. 

 This is ccitaiuly the case in all my citneifer, though some specimens are blacker 



than other.s. 



(3) The markings of the forewings are less yellow. 



The colour of the streaks on the forewnngs of omphrysus, e.specially of the 

 Bornean form, is often not yellower than in certain cuneifer; but in the latter insect 

 the fourth and fifth subcostal and the upper discoidal veins are black or almost so, 

 and the yellowish white colour is, therefore, more restricted, and forms almost a 

 diagonal band, which crosses the wing at the apex of the cell. 



(4) The black basal pari of the forewing, limited towards the ape.x bv the before- 

 mentioned yellowish white streaks, is horizontally cut off in amphryniis, while in 

 cuneifer it slopes off towards the outer margin. 



This character is very variable, lioth in finiphrystis and cuneifer, owing to the 

 individually different length of the streak which borders the upper median nervule 

 at its hinder side. 



(5) The hindwings have a greener tint in cuneifer. 

 This character seems to be fairly constant. 



(0) The veins of the hindwings are in c?<nej/er heavier black than in nmplirysns. 

 This is indeed the case; and I may add that the black band at the discal side 

 of the abdominal fold is broader in cuneifer. 



(7) T. cuneifer has on the hindwings from 3 to G submarginal black spots. 

 In my series of cuneifer the number of the spots varies from to 5. 



(8) In cuneifer the marginal black spot between the ujijier median nervules of 

 the hindwings is more prominent than the otlier marginal s|;ots. 



In one individual of cuneifer all the marginal spots are equally prominent 

 (exclusive of that between the loirer median nervules); and in some arnjihrysus the 

 spot in question is also more prominent than in the others. 



(9) The costal nervure of the hindwings of cuneifer is much less arched than in 

 amphrysua. 



In most specimens oi amphrysvs the costal vein is indeed more arched, but not 

 in all individuals. 



(10) The '• third and fourth " abdominal segments bear on the upperside a black 

 mark each, w^hich is entirely absent from the abdomen of amjjhrysxis. 



These spots, which stand on the fourth and fifth, not on the third and fourth 

 segments, are sometimes feebly indicated in .Tavan ampkrysus, and rather well 

 marked in many individuals of T. amphrysus flaricoUift (Druce), though never of so 

 deep a brownish black colour as in cuneifer; in the Sumatran representative form 

 of cuneifer — namely, in T. amphrysus sumatramta (Hagen) — the spots are not 

 develojjcd. 



(11) The abdomen ol cuneife)' is deep earth-browu above, greenish yellow at the 

 sides, and yellow below, while in ainphrysits the four basal segments are of a 

 dull ochreous colour above and at the sides, and the remaining segments and the whole 

 underside yellow. 



The abdomen is constant in colour in my e^ineifei; very inconstant in amphrysus.
