this disparity there is undoubtedly a close relationship between 
these two and the others, as indicated by similarity of venational 
and certain other body characters, as the presence of but one claw 
on the basal tarsus of hind legs. 
The close similarity between Kirkaldy’s Nesiope and my Car- 
sidaroida did not appear until the latter had been published, 
wherefore it becomes necessary to merge my genus with the 
other. The differences between the species are brought out in 
the following key: 
Key to the species. 
a 1 . Thoracic dorsum conspicuously striped with black (or brown) and 
yellowish (or orange) longitudinal bands; length of insect more than 
5 millimeters. 
b 1 . Forewings scarcely spotted, more or less fumate; insect large, 
usually over 7 millimeters long. (Philippines, Singapore, and A m- 
boina.) N. lieterocephala Crawford (’17: 165). 
b'\ Forewings conspicuously spotted in apical half with many small 
brown and large black spots. Insect about 5 millimeters long. 
(Larat and Java.) N. heterocephala intermedia var. nov. 
a 2 . Thoracic dorsum not as above, but with “a central pale line down 
dorsulum and mesonotum very narrowly bordered with black; sides 
of mesonotum broadly ferruginous, with two pale, curved, very 
narrow lines;” forewings spotted with brown in apical half. (Fiji.) 
N. ornata Kirkaldy (’08: 389). 
Nesiope heterocephala Crawford (’17: 165). 
Celebes and Amboina {Muir) , 5 males and 3 females. Sin- 
gapore {Baker), 1 pair. 
Type locality. — Luzon, Benguet, Baguio {Baker). 
Nesiope heterocephala intermedia var. nov. 
Similar to the species, except body of both sexes distinctly 
smaller and forewings with apical third or half dotted with 
numerous brown spots and several elongate, black spots. In 
some individuals of the species there is a slight spotting as in 
the variety, but this is not nearly so conspicuous. Genitalia of 
both sexes similar to the species but smaller. The maculation 
in this variety appears to be quite distinct from that of N. 
ornata, judging from Kirkaldy’s description and figure of the 
latter. 
Tenimber Islands, Larat {Muir), December, 1907, 4 males 
and 8 females. -Java, Buitenzorg {Muir), 1 male. 
Genus HQMOT0MA Guerin 
Although this genus bears unmistakable resemblance to other 
genera of Carsidarinse, its relationship is not wholly clear yet.
