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\ 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 Am- 



boina.) N. heterocephala Crawford ('17: 165). 



b 2 . 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*. 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 H0M0T0MA Guerin 



Although this genus bears unmistakable resemblance to other 

 genera of Carsidarinae, its relationship is not wholly clear yet.
