and wliich is distinguislied by the hind wings being several 

 times longer than the body, and quite linear, giving the 

 insect the appearance of a Nemoptera, in fact closely 

 resembling the Indian species of that genus, which I de- 

 scribed and figured in my Cabinet of Oriental Entomology, 

 under the name oi Nemoptera Jilipennis. (Plate XXXIV. 

 fig. 6.) The insect appeared, and still appears, to me to 

 be related to the family Arctiidm, and is mentioned under 

 that family in my " Introduction" (vol. ii. p. 389). 



In 1843, Mr. Edward Doubleday published a copy of 

 Wesmael's figure, together with the description aud figure 

 of an allied Indian moth, to which he gave the name of 

 Thymara zoida (Zoologist, i. p. 197), the type of which 

 from Northern India is in the British Museum collection. 

 He thus describes the veins of the fore Avings of this inte- 

 resting species : — 



" The neuration of the wings is very peculiar, especially 

 that of the posterior ; and I am by no means certain that 

 in these I have given the right names to the nervures" 

 which are thus described (see PL X. fig. D. 3). 



" Costal nervure straight, attaining the costa consider- 

 ably beyond the middle; subcostal nearly parallel with 

 the costal nervure, bent downwards beyond the middle, so 

 as partly to close the discoidal cell; from which portion 

 two nervules are thrown off to the outer margin, whilst 

 the third proceeds in a direct course to the costa just 

 before the apex; median nervure four-branched, the ner- 

 vules attaining the outer margin at about equal distances: 

 discoidal cell divided longitudinally by a false nervure 

 which bifurcates at its extremity, one fork striking the 

 discocellular curve of the subcostal, the other the median 

 nervure above and beyond the point where the second 

 nervule from the base is thrown off, thus closing the dis- 

 coidal cell: radial nervure replaced by a very faint, false 

 nervure." 



In 1876, my attention was directed by M, Borre, the 

 distinguished entomologist at the head of the Entomolo- 

 gical Department in the Brussels Museum, to the original 

 type of the former genus Himantopterus, which is now 

 in the collection of that Museum, and I took the oppor- 

 tunity of carefully examining and delineating the veins 

 of the fore wings, my attention having been recently 

 directed to that subject in investigating the typical ar- 

 rangement of these organs in the Heterocerous Lepidop- 

 tera, as partly illustrated in my memoir on the Castnice,
