3o8 LLOYD'S NATURAL HISTORY. 



thesub-costal ncrvure is five -branched, with two branches thrown 

 off near together before the end of the cell ; the third and fourth 

 fork half way between the rather pointed cell and the tip, 

 while the fifth forks just beyond the cell. The upper disco- 

 cellular nervule is present, the first discoidal nervule being 

 emitted from the cell. There is a short internal nervure and 

 an oblique cross-nervule connecting the median and sub- 

 median ncrvures near the base. On the hind-wings the pre- 

 costal nervule is present, and curved, and there is a cross- 

 nervure connecting the costal and sub-costal nervures at the 

 base ; the second sub-costal nervule is absent ; the cell is very 

 small, and all the remaining nervures are very long, the upper 

 median nervule running down to the extremity of the tail. 



GENUS LEPTOCIRCUS. 

 Leptocircus, Swainson, Zool. 111. Ins. ii. p. io6 (1832?); 

 Boisduval, Spec. Gen. Lepid. i. p. 380 (1836); Double- 

 day, Gen. Diurn. Lepid. p. 22 (1847); Schatz, Exot. 

 Schmett. ii. p. 47 (1886). 

 This genus includes only a few species, very similar to each 

 other, which have a wide range over the Indo-Malayan Region, 

 but do not appear to extend beyond it, except to Celebes. I 

 have figured the type, which is also one of the commonest 

 species ; it is found in India, Malacca, Java, <S:c. The species 

 of Leptocircus are said to hover over water in company with 

 Dragonflies, which some observers say they resemble on the 

 wing.
