AMBIA. — DITOMOPTEEA. 
179 
near the outer angle, not curved round and joined to a large patch near the inner margin, 
this patch being almost completely wanting. Hind wing with the postmedial band obso- 
lescent, narrow, and suffused with black ; the submarginal band narrow. Cilia black below 
the apex of hind wing and at middle of outer margin and apex of fore wing. 
Ambia cceruleata. (Plate CLXXIV. fig. 29.) 
Expanse ^ inch. 
Female black. Fore wing hardly excised below the apex ; an antemedial line of metallic- 
blue scales ; a white spot at end of cell with a few metallic- blue scales round it; some sub- 
marginal patches of metallic-blue scales ; cilia fuscous, white below the apex and above outer 
angle. Hind wing with the excisions strongly marked ; indistinct subbasal and postmedial 
pale lines ; some small submarginal patches of metallic-blue scales. Cilia white at the 
excisions below apex and above anal angle. 
DITOMOPTERA, g. n. 
Male. Antennae simple and annulated. Palpi with the second joint long, porrect, and 
thickly clothed with scales, the third joint short and depressed. Fore wing with a deep 
incision in the outer margin between the subcostals and the upper radial, and a slighter 
incision between the first median and submedian; first subcostal anastomosing with the 
costal, the second given off from just before the end of the cell, the third from the end, the 
fourth wanting, the fifth from below the end ; upper radial from the middle of the disco- 
cellulars ; the lower radial and two medians from close to the end of cell ; the first median 
from below the end ; a submedian nervure. Hind wing with a deep incision in the outer 
margin between the median and submedian nervures ; the cell very oblique ; the subcostals 
from the upper end of the cell, which is very short ; the first subcostal anastomosing strongly 
with the costal ; radial from the middle of the discocellulars ; the three medians from near 
the lower angle of cell ; three internal nervures. Cilia of l)oth wings very long. 
Ditomoptera minutalis. (Plate CLXXIV. fig. 31.) 
Expanse -^^ inch. 
Male ochreous. Fore wing wholly suffused with brown, except the apex, which bears a 
white longitudinal streak; subbasal and antemedial very indistinct dark lines ; an indistinct 
line from the lower angle of the cell, curving up to the costa, then descending to near the 
outer angle and forming a ?-shaped mark; a dark marginal line and two dark lines through 
the cilia. Hind wing pale fuscous, with marginal and cilial lines as on fore wing. 
Female. Fore wing with scarcely any brown suffusion and the markings more distinct; 
the hind wing paler.
