middlp joints is scarcely one-half the breadth of the body of the joint (PI. IV. fi^. 5). 

 The sides of the joints are convex ; the fine liairs about oue-third or one-fourth of (he 

 length of the joints, and all of nearly equal length. The ventral bristles are slicrhtly 

 longer than the joints ; the larger subdorsal bristles are aliout half as long again as 

 the joints, and the dorsal fine bristle.s remain very Ihiii and have nearlv (he lengdi 

 of the joint. 



The antennae of A. versicolor- (Don.) are similar to those of caricae; but all the 

 joints except the terminal one are liroader (vertically) than long, the setae are 

 stronger, and the sides are very faintly flattened in the middle close to the dorsal 

 scaled portion ; the fine hairs are extremely faintly longer at base and apex of the 

 median joints. 



The antennae of A. plaginotn. (Kutl.J are of tlie helicoma-t\\)e, and therefore 

 quite different from those oi cariaie. 



The bulk of the species of Asota — in fact all species exclusive of caricae, 

 versicolor, contorta, and an undescribed species allied to cmitorta — have the antennae 

 of the heiiconia-tyite, and differ from caricae in liaving a lateral impression on 

 each joint (except apical one), and in tlie fine hairs in fi-ont of and behind this 

 impression, or the hairs all along apical and basal edges, being prolonged. 



A. plana (Wlk.) and allies come nearest to A. caricae (F.) and versicolor 

 (Don.). Tlie last ten or twelve joints (except the penultimate one) are longer than 

 broad; the middle joints are about one-fourth broader than long. The impression 

 mentioned before is rather slight, deepest near the large subdorsal bristle, and 

 gradually fades away vent rally ; the edges of the joint are somewhat raised near 

 the impression, and the hairs on these slight ridges are much prolonged, being about 

 of the length of the joint. 



The antennae of A. albiveita (Wlk.) = vitessoides (Snell.) are similar, but all 

 the joints except the apical one are broader than long. 



The impression becomes deeper in A. hdiconia (]>.) (I'l. IV. fig. 10); the edges 

 of the joints are more raised ; the ridges are, however, not on the same level, but 

 the basal one is more dorsal, the apical one more ventral. In consequence of the 

 different position of the ridges, a front view of a detached middle joint from the 

 distal .side shows a dilatation of the joint in the ventral half (PI. IV. fig. 8), while 

 I he joint appears broadest in the dorsal half when it is viewed fi-om the basal side 

 (PI. IV. fig. 9). The hairs on the ridges are longer than in A. plana (Wlk.); when 

 looked at from above, these hairs protrude at each side like brushes; the two 

 brushes nearest to a subdorsal bristle belong to two subsequent joints (PI. IV. fig. II). 

 The large subdorsal bristles are more than three times as long as the joint ; all the 

 joints are broader than long, except tin' terminal one; the middle ones are about 

 half as broad again as long. 



In A. er/ens (Wlk.) and allies the impression is still deeper, the cariniform 

 (ventral) portion of the joints is higher, and the bristles are stronger. 



The (bird chief modification of the male antennae is found in A. contorta 

 (Anriv.) and an undescribed Bornean sjiecies, not in A. toi'tuosa (Moore), to which 

 Snellen puts contorta (Auriv.) as a synonym, by mistake I think. Mere the apical 

 ten joints, inclusive of the penultimate one, are longer than broad. The ventral 

 subcariniform dilatation of the joints as.sumes quite a different aspect from that 

 of the lieiiconia-type, in consequence of its becoming (longitudinally) very .short, 

 being about half the lengt h ol I lie stem of the joint, and being transversely dilated. 

 The two lateral ridges of the hcl icoiua-ty\tc stand here very close together, as the
