Gastnildae, Psychidae, aud certain Noctuidae (Gatocala) as licing provided with 

 " sinus-scales." I find, however, that the sinus-scales are much more widely dis- 

 tributed amongst Heterocera, and that the term " Rhopalocera-scale " for sinus-scale 

 and " Heterocera-scale " for scales without sinus, as applied by Kolbe, Einft'/liruiuj in 

 die Kemdniss der Insecten p. 32 (1893), is misleading, aud cannot be accepted. 

 In Agamddae sinus-scales are present amongst scales without sinus in all species, 

 and in Neochera marmorea and hhdiod/mi, nearly all the scales of the upper layer 

 on both sides of either wing, which scales assume a metallic bluish gloss in certain 

 lights, have a sinus, while the scales of the under layer are, to my knowledge, 

 without sinus. Sinus-scales are also very common on the wings of Agaristidae. The 

 scales with and without sinus are connected by all intergradations. The stridulatory 

 patch of thick scales on the upperside of the hindwing is, in Xeochera as well as in 

 Asoto,, composed of sinus-scales (PI. IV. figs. 44, 45), whereas the fold on the underside 

 of the forewing is clothed with scales without sinus. 



The following Afjanaidae belong to Neochera Hb. : — 



N. dominia (Cram.), eugenia (Cram.), sUbostethia Butl., hasUlss'i, (Meyr.), 

 butleri Swinh., heliconides Snell. = zaria Swinh., niarmorea Wlk., bliatvami JNIoore, 

 inops (Wlk.), privata (Wlk.), and cinerascens Moore. 



The other insects standing in Kirby's Catalogue under Neochera must be 

 referred to Asoia. 



Those eleven names belong to insects of tlu'ee ditferent types, each type repre- 

 senting, in my opinion, one species, so that there would be only three species of 

 Neochera ; for want of intergradations, however, bhaivana and eugenia must at 

 present still be kept separate from marm&rea and dominia respectively, so that 

 the number of species is five. 



1. /ftops-type. Here belong inops (Wlk.), privata (Wlk.), and cinerascens 

 Moore; the latter is a synonym of privata (Wlk.). The antennae are, as in all 

 Aganaidae except Aganais Boisd., com^iressed. In the nude each joint is clothed 

 with long and with short thin hairs ; the long ones are shorter than the joint, and 

 dispersed all over the not-scaled portion of the joint. The two apical joints are of 

 nearly equal length — the apex of the terminal joint is, as in the other Aganaidae, 

 produced into a Ihin cone — and are about one-fifth longer than broad ; the preceding 

 joints are relatively and absolutely longer than the two apical ones; from the apical 

 third of the antennae, towards the middle, the joints become gradually shorter and 

 higher, and are from the middle to the base of the antennae shorter than vertically 

 broad. 



The female antennae are thinner than tiiose of the nude, all the joints except 

 those of the basal fourth are longer than broad, and the hairs and bristles are shorter 

 than in the nude. 



The claspers of the nude (PI. IV. fig. 28) have lost the solelike form usually 

 pi'esent in Aganaidae. They are broad and outwardly convex at the base, and their 

 apical half is transformed into a strongly chitinous hook, furnished at the inside 

 half-way down to the base with a rather broad dilatation from which projects ventrally 

 a sharp tooth. The claspers are without a clothing of hairlike scales at the inside, 

 but are hairy outside. The dorsal, more chitini.sed, portion of the clasper turns at 

 the base round towards the bipartite harpe, which consists of two sticklike pieces, 

 one with nearly its entire length joined to the clasper, the other projecting free. 

 There is little variation in the form of this apparatus, as it seems; the median
