Imago. — Wings small. Forewing ti'iangular, the anterior and exterior margin 

 nearly equal in length, the posterior margin about half the length of anterior, apex 

 obtuse ; first subcostal veinlet emitted at fully two-thirds before end of the cell, 

 second at one-sixth before the end, third and fourth at fully one-third beyond the 

 end of the cell, fifth from a short distance beyond end of the cell below the latter ; 

 cell extending to about half length of the wing ; upper and middle discocellulnr 

 inwardly oblique, the upper longest, upper radial from their angle, lower discocellular 

 positioned so that the lower radial appears as it were a fourth median branch ; the 

 median and submedian vein with a very slender short cross-veinlet near their base ; 

 submedian vein much recurved from the base and with a lower basal lengthened 

 slender veinlet extending to the posterior margin, Ilindiving short, much prolonged 

 posteriorly, anterior margin straight, the base much lobed, exterior margin 

 scalloped anteriorly and sinuous posteriorly, the middle being gradually produced 

 into a very long slender tail, the anal angle pointed ; abdominal margin long, 

 fringed with fine hairs, and in the male of L. Curius grooved near the base along 

 the submedian, and i\\eve furnished loitli a radiating hift of white androconial hairs ;j- 

 precostal veinlet long, very slender, curved ; interno-basal costal cell distinct ; 

 discoidal cell very short and narrow; second subcostal veinlet emitted at one-half 

 before upper end of the cell ; discocellulars extending very obliquely outward, 

 slightly bent, the radial from their angle ; middle and lower median veinlet emitted 

 from near end of the cell, the upper median extending to end of the tail ; sul)median 

 vein long. II odij stout ; head large, front broad and hairy; e3'es prominent ; palpi 

 very short, clothed -with long loose scales ; antennje rather long, slender, the club 

 short and compressed. Legs rather long, slender; anterior tibia with a stout lateral 

 spur covered with scales; tarsi longer than the tibiae and latei'ally spined, the first 

 joint equal in length to the others combined ; claws simple in both sexes of L. Mege^, 

 bifid in L. Curius. 



Lakva. — According to a figure, kindly drawn for us from memory, by Col. C. T. 

 Bingham, who found and reared it in Burma, the larva is very much like that of the 

 genus Thais. 



Type. — L. Meges. 



Habits of Imago. — The species of Leptncircus, according to the observations of 

 Mr. A. R. Wallace (I.e.) "frequent water, often settling on the edges of rdls, or 



* Lampropteryx, used in 1829 for a genus of Lepidoptera. 



+ This tuft of hairs has only been observed in the miles of the white-handed species. In the numerous 

 males of the green-handed species that we have examined this tuft has not been detected.
