My single specimen ("S ) is in such poor conrlition that I am still 

 doubtful whether it should be placed under this title, or that of (hirius. 

 I located it temporarily under this species, though the other would have 

 answered equally as well, for the purpose of contrasting it with the 

 following new and very distinct species. It may perhaps be L. Corion. 

 (jray, of which, however, 1 have seen neither figure nor description. 



30. Leptocircus Wilsonii, nov. sp. 



Upper surface black; abdominal margin of posterior wings chocolate- 

 brown, fringed with long hairs; apical half of fore wings hyaline, and 

 bordered as in Mcges ; common pale green band on the wings, termi- 

 natin"- on the disc of the secondaries in a white streak as in Mcqea ; but 

 that part on the primaries is, in the nude, simply a narrow pale green 

 line; in the /hnale, it is half the width of the band on the posterior 

 wings; the lower half of which, together with the tail, is irrorated with 

 brilliant white atoms; this last, which is not recurved at its extremity, 

 and the indentations above it, are bordered with white, as in Meges. 

 Expanse 1.50 inches, % ; 1.62 inches, 9 . 



Under surface, the common band is shining, pearly white on both 

 wings ; base greenish-white. In the male, a white lunule on the anal 

 margin, followed by a small dot, and an oblong dash of the same color; 

 in the femaU^ the white luue is followed by two small dots, the last 

 situated anteriorly. 



Body black, with two lateral white lines on each side of the abdo- 

 men; palpi whitish; antennae black, club white at the tip; claws bifid. 



Hah. — Philippines, (In my collection.) 



I have dedicated this pretty little species to Dr. Thos. B. Wilson, of 

 Philadelphia. 



This genus is certainly well represented, and considering its compa- 

 rative rarity, appears to be quite common in the Philippines. It is 

 with regret that I cannot give a diagnosis of the larva, as it would 

 enable us to determine with certainty its position, at present very ano- 

 malous, in the family PapiUonulse.
