EUPLOEA. By H. Fruhstorfer. 
Under surface more delicately dotted with blue throughout, the rows of dots on the hindwing not continued 
odmgdensis. to the anal angle even in the ?. Burn. — dodingensis Moore is characterized by the strikingly broad sexual 
stripe of the forewing in the cfcf and the uniform dark brown colouring of the upper surface. Dots on the 
varina. underside even more reduced than in duponcheli. North Moluccas: Halmaheira, Batjan. — As ab. varina form, 
nov. we indroduce an interesting aberration with a row of light brown submarginal patches on the forewing 
above, which beneath are magnificently blue-white. The hindwing bearse long whitish violet intramedian 
moluccana. streaks. Both wings distally tinged with steel-blue. Batjan. — moluccana Swinh. is the darkest of the 
Moluccan races, altogether smaller than dodingensis , ? above sometimes with two or three small median dots. 
Dots of the under surface very delicate, similar to those of dodingensis. No representatives of duponcheli 
are yet known from New Guinea, but two species occur commonly on the Solomons. 
fraudidenta. E. fraudulenta Btlr. cf somewhat larger than anthracina, with dark brown androconia-spot, filling up 
the whole cell, and light brown anal margin on the hindwing. ? above dark brown, with darker marginal 
area, a rather large white cell-spot and two transcellular spots, cf with the sexual stripe on the hindwing 
very long, yet only a third broader than in anthracina. The under surface of the forewing is characterized 
by a long, concave, somewhat sausage-shaped whitish violet spot, bent downwards at the sides, placed between 
the middle and lower median veins before the grey cell-stripe which shines through from beneath. In the ? 
there is further an unusually long band, extending to the base, likewise whitish violet, which occupies the 
inner margin of the forewing behind the submedian. Under surface of the hindwing as in anthracina, but 
with two rows of very large antemarginal dots. Widely distributed on the Solomon Islands: Shortlands, 
Bougainville, Ghoiseul, Ysabel and Rubiana. On Renonga Ribbe captured a specimen with whitish sheen on 
lystra. the upperside of the hindwing. — lystra subsp. nov. Habitually smaller than fraudulenta , with reduced white 
discal dots on the forewing and more uniformly light brown hindwing. Underside of the forewing in addition 
to the usual cell-spot and 2 transcellular patches with a row of 3 thin striae before the apex of the cell, 
which are wanting in the other fraudulenta- forms. Treasury Island. 
nechos. Finally, E. nechos Math., with more rounded wings than the preceding, has the sexual bands of the 
forewing nearly 1 cm. in breadth. Ground-colour somewhat lighter brown, the characteristic intramedian 
stripe on the underside of the forewing shorter than in fraudulenta, distally deeply incised, proximally not 
excurved posteriorly. Antemarginal patches of the hindwing mostly absent. Ribbe met with the species up 
to many thousands on the small Solomon Island Mania, whole swarms were frightened up when anyone passed 
through the thickets; and in some places, where the natives had cut down wood, whole crowds of Euploeids 
were resting on the flower-covered stumps. Even in the dense forests there was not a twig and scarcely a 
leaf of the lower bushes on which a nechos was not settled. Bibbe learned from the natives that such swarms 
occur periodically, about every 10 years. Shortlands Islands, Bougainville. 
megaera. E. megaera Btlr. is only known to me from the description. Ground-colour dark brown, the hindmargin 
lighter. Five subapical spots are placed in an oblique row. ? with a cell- and a costal dot and a row of 
small indistinct submarginal spots, cf with three subapical dots on the paler hindwing, ? with two rows of 
subapical dots. Under surface lighter brown than upper; cf with 7 antemarginal dots. Aru Islands. 
E. morosa (= dalmani Fldr .) is an interesting species, and is the easiest to determine of all the 
Crastia. The sexual spot inserted between the middle and lower median vein is placed quite near to the 
morosina. distal margin of the forewing and moreover is almost rounded instead of elongate and stripe-like. — morosina 
subsp. nov. (82 d). Above deep velvety black, hindwing with whitish grey costal margin and quite narrow 
black androconia-patch. Under surface with a violet cell-dot, two discal dots and an elongate, distally pointed 
intramedian stripe, which is placed exactly over the oval scent-spot. Hindwing besides the cell-spot with 5 
morosa. violet discal and 3 subapical dots. ? somewhat lighter brown, above without a trace of dots. Obi. — morosa 
Btlr., described from Halmaheira, not rare also on Batjan, is somewhat larger than the preceding; scent-spot 
elongate and larger. Under surface with more delicate discal dots than in morosina. 
E. pierreti, described from Dorey (Dutch New Guinea), has the sexual spot likewise very near the distal 
margin of the forewing. It. varies in length in the separate local races, but in all the forms is somewhat 
numantia. curved down distally. -- numantia subsp. nov. (80 b) shows a shorter sexual patch, which in some cfcf is 
somewhat narrower, but in others broader than on the figure, where unfortunately it. could not be brought 
out very distinctly. Under surface of both wings basally dark coffee-brown, the distal margin of the hindwing 
shaded with whitish yellow. Forewing with a cell-dot and 2 or 3 discal dots, hindwing with a cell- and 5 
pierreti. discal dots. Not rare; Waigeu. — pierreti Fldr. is above somewhat lighter brown throughout than numantia ,
